CO2, Cold Chain

Following the successful delivery of numerous natural refrigeration projects within the health sector, Green Cooling recently provided a Panasonic CO2 Condenser unit supplying a walk-in freezer at an M&S Simply Food franchise located within a large NHS Hospital. For this project Green Cooling provided a system that included a Panasonic 2kW CO2 Condenser unit (2kW at -30C) with RDM control incorporating remote monitoring, along with the cold room structure and associated services. The project was of a significant size and involved the refurbishment of existing areas within the hospitals main entrance to provide an increased level of service for the hospital visitors. Garry Broadbent of Green Cooling commented, “Alongside providing a retail environment that delivers the highest level of service to the hospital, a project of this nature also calls for the most practical, efficient and sustainable refrigeration solution, which is why Green Cooling selected the Panasonic CO2 system to provide real benefits”. Delivering class-leading low temperature efficiency (over 25% more efficient than the previously used F-Gas HFC refrigerant) the Panasonic Condenser units also achieve the lowest noise levels and are importantly provided with a 5-year compressor warranty.
In terms of sustainability, the projects natural refrigerant CO2 credentials mean that the installation sits outside the F-Gas refrigerant phase out legislation and regulations. This means from a-users perspective, the installed Panasonic CO2 refrigeration system not only provides the highest levels of efficiency but also future proofs the site against any cost or availability implications resulting from current or future F-Gas legislation.
Since its European launch in late 2017, the Panasonic CO2 Condenser range has proven to be attractive to specifiers, with over 250 units now being installed across Western Europe and where a modular approach to medium and lower duty applications is required, as was the case in this application. Neil Bilton, Head of Key Accounts at Panasonic UK further explains more about the benefits, “The Panasonic range has been specifically developed for small to medium capacity applications within the retail and food service sectors and is particularly suited for installations in small supermarkets, convenience stores and garage forecourt retail operations. Furthermore, the range is also ideally suited to provide refrigeration within the restaurant and hotel sectors.” The units are compact, lightweight, have low noise levels (a range of 35.5 dB(A) to 36dB(A)) and designed to fit into smaller spaces with dimensions of (HWD) 930mm x 800mm x 350mm and weighs only 67kg. Panasonic is not new to this product range, having developed the latest version of the Panasonic CO2 Condensing units over time, with over 8,500 units being installed in Japan in approx. 3,700 stores since its launch in 2010 and thus building up essential knowledge and understanding of the end user experience and challenges.  This solution helps to overcome some of the major hurdles that small retail outlets encounter with previous solutions that are currently on the market. The Panasonic units offer a stable and reliable system that helps to maximise energy efficiency with a low carbon footprint. Furthermore, the units can be set to run at low and medium temperatures with four initial settings which can be modified by turning a simple and user-friendly rotary switch to further enhance energy savings. Project summary: This project successfully delivered a natural refrigeration solution to meet the clients’ sustainability and efficiency requirements.
Garry Broadbent of Green Cooling further added “This type of modular installation is typical in terms of the direction that food retail stores and catering facilities are heading. Sustainable food retail refrigeration solutions are now required to future proof the operation of a site and remove any operational risks, resulting from the F-Gas HFC refrigerant phase out legislation, in terms of both refrigerant costs and quota restrictions.”
From a legislation and compliance perspective, the use of CO2 in the above installation removed the need on this site for F-Gas reporting and hence there is also no inclusion required within the operators Green House Gas (GHG) report, as no F-Gas refrigerants are utilised.
In summary, within this application, the Panasonic CO2 units provided a practical solution which combined the highest levels of efficiency and practicality along with a value-based focus with regards to both capital and whole of life costs.

Smart Neo-Georgian Home Kitted with Panasonic Heat Pumps

Cambridgeshire, UK

Aquarea air to water heat pump, Domestic air to air heat pump, Residential


Energy conscious homeowners, Vincent and Jacqueline Haines wanted to create an eco-friendly home for their outstanding Georgian style, 570sqft self-build project in Cambridgeshire. Amongst several sustainable elements to the three-storey residential property, such as triple glazing throughout and 43 solar photovoltaic panels, this high-spec 6-bedroom home is heated via two Panasonic Aquarea T-Cap Air-to-Water Heat Pumps. The family was looking for a reliable and renewable heating source to connect to two floors of underfloor heating for the property, in addition to a cost-effective supply of hot water for the kitchen and bathrooms. The property is in a moderately remote location, and with potential piping issues at the site, the family’s heating specialist, Roland Gurner from Eco Installer investigated various renewable options and recommended two Panasonic Aquarea T-Cap Air to Water Heat Pumps for the property.  The heat pumps were supplied from authorised UK distributor for Panasonic, Oceanair. Homeowner, Vincent Haines comments “Panasonic is a well-known, reliable efficient brand and proved excellent value for money. As an IT Consultant working from home, we opted to have smart remote controllers throughout the property, thus allowing us to monitor usage in each room. Our installation was completed 2.5 years ago, and since its installation, we have found the system to be reliable and energy efficient with the added benefit of a constant supply of free hot water.”
It has always been a dream of trained architect, Jacqueline Jiang-Haines, to design and construct her own home. The original purchase of the site was some ten years prior to the build. The 2.4-acre plot of land has far-reaching views and offered plenty of scope for the couples’ ambitious self-build to take place. The site also had an existing property on the land where the couple lived for ten years and when the time was right, put fencing around their existing home, which left them with 2.1 acres with a driveway leading down to where the new dwelling would be, at the back of the plot. The couple were able to live in the original property during the 12-month construction phase, which meant they were able to keep a close eye on progress.
The couple went through several design styles for the house before settling on a neo-Georgian style design, this was partly due to a nearby property being of a similar design and with the couple preferring a more traditional brick and block construction, which suits the style. “We both like the solidity it offers, and we felt that ultimately it would give us more control over the layout we wanted to create.”
Roland Gurner of Eco Installer adds “It was beneficial to be involved early on in this project, allowing us to look at the optimum space available for the units and advise on the best renewable solution. Two Panasonic Aquarea T-Caps were specified, partly because of the size of the property, plus it also means that when demand in the summer is lower and only the hot water is required, only one of the units is needed – of course this is also beneficial for the long-term impact and longevity of the system.”
“The Panasonic Aquarea T-Cap Air to Water Heat Pumps are very quiet compared to its competitors, aesthetically pleasing and highly energy efficient (COP of 5,08)” explained Tony Holland from Oceanair. “The T-Cap stands for Total Capacity and ideal for maintaining the heating capacity even at very low temperatures. The T-Cap range is an ideal solution for this project as it can also be connected to a solar kit and smart controls in order to further increase efficiency and minimise the impact on the environment which is precisely what the Haines family were looking for.”
The Panasonic Aquarea range is renowned for delivering major energy savings for residential homes thanks to its incredible efficiency levels. The Aquarea system operates by transferring heat instead of generating it. The range uses a renewable, free energy source (the air) to heat or cool the home in addition to producing hot water. The T-Cap line-up can maintain the heat pump output capacity until -20oC outdoor temperature without the help of an electrical booster heater.
The range is designed and produced by Panasonic and among the technologies listed on the International Energy Agency (IEA) Blue Map, whose goal is to reduce CO2 emissions to half the levels emitted in 2005, by the year 2050.
The Haines family enjoyed their self-build journey are now looking forward to their next renewable and eco-friendly project.

20 New Homes Installed with Panasonic Aquarea Air Source Heat Pumps

Spire View, Cambridgeshire, UK

Aquarea air to water heat pump, Residential


Spire View, a development of 20 new executive four and five-bedroom homes in the market town of March in Cambridgeshire by James Development Co Ltd, has been equipped by Panasonic distributor Oceanair with renewable Panasonic Aquarea Monobloc air to water heat pumps to supply heating and domestic hot water to each home. With sustainability and quality high on the agenda for this new modern development in popular March, Cambridgeshire, making the right choices through intensive research for all elements in the specification throughout the properties, was very important to the developer.
Marcel Cooper, Construction Director of James Developments commented, “We  find that today’s prospective purchasers are far more aware of environmental issues, emissions and the need for their homes to be sustainable. Purchasers increasingly  look for cleaner, greener homes and are far more mindful of potential running costs. By comparison, we installed air source heat pumps in a development of 36 homes about ten years ago but then, purchasers were not aware of the benefits and economies that air source heat pumps offered although they were all very pleased with the way the homes functioned once they had moved in. Now, information online and in the media has made the average purchaser visiting site today more aware that air source heat pumps are a desirable way to provide renewable heating.”
Tony Holland - Southern Area Account Manager for Oceanair added, “Following the initial decision to go with the Panasonic systems, we had various meetings with all parties to agree on all aspects of choosing the correctly sized system and position of each individual install at Spire View, deliveries to suit the progress of the development and full training for all the engineers working on this side of the project. This has been a team effort between Oceanair and Panasonic from day one when we witnessed the archaeological dig on site through to the installation of each system in the fully built residential estate and the final result of a very satisfied customer which we always strive to achieve and gives the most satisfaction”.
Spire View consists of 20 new high end executive four and five bedroom homes, with the four bedroom homes having one en-suite and a family bathroom while the five bedroom homes have three en-suites and a family bathroom so the adoption of  large, high efficiency Panasonic Aquarea hot water storage tanks is the ideal way to provide a constant and abundant supply of domestic hot water for the occupants.
The Aquarea Monobloc is extremely energy efficient with a COP of 5.08 for the new 5kW range, is very quiet in operation and offers a superb and sustainable alternative to traditional boilers with zero emissions at point of use and a lower carbon cost than  mains gas, oil, LPG and direct electric. Furthermore, all residents will benefit from reduced heating and hot water bills.
Marcel further went on to explain “after comparing the benefits and costs of air source heat pumps with a traditional gas boiler solution and the attendant cost of bringing a gas main into the site and installing all the service ducts and meter boxes etc., we came to the conclusion that air sourced heat pumps were more cost effective and beneficial for us, as the developer, for our purchasers and most importantly, for the environment.
Furthermore, we researched air sourced heat pumps currently available, often dealing with manufacturers directly but ultimately we were guided by Tony Holland at Oceanair, whose personal and attentive service, market knowledge and in depth product awareness led us to specify the Panasonic system which offered the optimum balance of high energy performance, perceived quality, an internationally trusted brand, good and approachable technical back up, advanced technology and a fair price.
Tony Holland of Oceanair further commented, “It is important, when buying a heat pump, to choose a reputable manufacturer who will provide a quality service, a comprehensive warranty and provide proper guidance about the buying and installation of heat pumps. The initial outlay of a sustainable heating system may be slightly higher, however buying from a reputable manufacturer will ensure a high-quality, long life product, low maintenance costs and the peace of mind that you’ve made an optimised investment. A reputable manufacturer will also have the confidence in their products to offer a comprehensive warranty, such as Panasonic’s seven-year warranty*1.”
Tony Lathey, Panasonic’s UK Air to Water Pre-Sales Manager further added “Up to 80%*2 of the energy generated by air source heat pump comes from the air, with electricity making up the remaining 20%, so not only is this an extremely cost-effective alternative, but it is also environmentally friendly. With increasingly volatile energy prices, an air source heat pump is a great option to reduce overall energy bills by up to 60% (when compared to fossil fuel alternatives).”
The Aquarea Mono-bloc line-up can maintain the heat pump output capacity until -15oC outdoor temperature without the help of an electrical booster heater. The range is designed and produced by Panasonic and among the technologies listed on the International Energy Agency (IEA) Blue Map, whose goal is to reduce CO2 emissions to half the levels emitted in 2005, by the year 2050.The Spire View Development is nearing completion (July 2019) with many of the homes now ready to move into.

Panasonic Provide First CO2 Solution for Refrigerated Trailer Rental


Commercial, Others

CO2, Cold Chain

The Panasonic CO2 Cold Chain Condenser units provided the perfect mobile refrigeration solution for cooling specialists, Greencold. A reliable, efficient and eco-friendly solution to cool and freeze a mobile trailer was required and where the Panasonic CO2 units have now been installed. Simon Andrew, Director of Greencold commented “We had always wanted a large cold-room test facility in our premises to enable us to carry out product testing for our customers for both chill and freeze temperatures. However, due to limited space inside our workshop we decided that it would be a better idea to construct a mobile CO2 cooling system in a refrigerated box trailer. This could then be parked both on our premises and also taken to our customers site to test their products locally or demonstrate the technology. Panasonic worked with us to develop a perfect solution”.
The Panasonic CO2 units are compact, lightweight, have low noise levels (a range of 35.5 dB(A) to 36dB(A)) and designed to fit into smaller spaces with dimensions of (HWD) 930mm x 800mm x 350mm and weighs only 67kg.
The condensing units use a natural refrigerant that has a GWP (Global Warming Potential) equal to 1 as opposed to the current refrigerant typically used such as R404A having a GWP equal to 3,800. With refrigeration legislation increasing over the coming years, HFC R404A will be out of circulation by 2020. Paul Taylor, UK Sales Manager for Panasonic UK further explains more about the benefits, “The Panasonic range has been specifically developed for small to medium capacity applications within the refrigerated retail and food service sectors. Furthermore, by combining reliability and efficiency with the natural refrigerant CO2, the range removes any risk of future costs associated with the F-Gas refrigerant phase out whilst also minimising energy use and operating costs.”
With the Panasonic CO2 units already having a proven track record for reliability and efficiency with a clever single two stage temperature compression condensing unit and of compact size, Simon Andrew went on to explain, “We were able to combine the Panasonic units with a suitable air cooler of sufficiently high working pressure from a cooler manufacturer, we knew we had a great solution”.
Greencold have also since identified their refrigerated trailer as an educational tool where they take it out to customers and prove the eco-friendly CO2 cooling system is nothing to be frightened about.
With changes to the F-Gas regulations coming into force, alongside reducing carbon emissions and energy costs becoming key drivers for change in refrigeration systems, both specifiers and end users are recognising the need to consider CO2 as a refrigerant.
Greencold have also identified a further revenue stream and use for the Panasonic CO2 trailer and set up a sister company called ‘QuickFreeze’, whereby they are successfully renting out the branded trailer to a variety of customers in the food manufacturing business for events and storage logistic sectors such as smaller catering, hotels and restaurants, corporate hospitality events, weddings, pop-up stalls and emergency back-up for food and medical pharmaceutical companies with refrigeration needs.
One recent use case was where QuickFreeze were contacted by a youth football club for a large team tournament event where the refrigerated trailer was required for a three-day event. The Trailer was parked in a convenient onsite location and placed next to a portacabin where food was being prepared.
Chris Terry, Team Chairman of FC Aztec Youth commented, “We commissioned Quickfreeze to set up the trailer for chilled conditions which enabled us to serve the food and replenish the stocks quickly, allowing us to store all our products in the vast amount of space and all kitted out with convenient shelving. The event ran trouble free for the whole of the tournament from Friday to Saturday evening and made our life a lot easier. The CO2 branding on the trailer also caused a few heads to turn and brought attention to the visiting public and showed the importance of green refrigerant technology”. The Quickfreeze trailer is helping to avoid the logistical challenges faced when delivering refrigerated solutions in an articulated HGV lorry, which is not always convenient for many smaller drop-off locations.
The Panasonic CO2 units offer a practical and straightforward method of installation with complete design support available through the distributor network. The units are compact, lightweight and have very low noise levels. Based on Panasonic monitored data, 16% energy savings for chilled refrigeration and 25% energy savings for lower temperature freezer applications have been achieved in comparison to R404A.*” Simon Andrew further added “We are happy to be collaborating with Panasonic and assisting them in spreading the word about the benefits of CO2 and demonstrating its technology”.

UK Based Food Factory Installs Panasonic CO2 Commercial Refrigeration to Cool and Freeze Sushi


Commercial, Restaurants

CO2, Cold Chain

Tanpopo Japanese Food, a UK-based food wholesaler, has recently equipped its warehouse in Feltham, West London, with condensing units from the Panasonic CO2 Cold Chain range. The units were installed by Versan Ltd of Chertsey, Surrey, a company that specialises in the installation of refrigeration technology.   For over 20 years, Tanpopo has been making and supplying sushi to catering companies, supermarkets, hotels, stadia and event organisers across the UK. With the use of renewable technology and reliability high on the agenda for Tanpopo, Panasonic’s Cold Chain Commercial Refrigeration range, which uses environmentally-friendly CO2, was the ideal choice for all their frozen and chilled food storage refrigeration requirements when the business moved to its new premises in Feltham.   Peter Bigmore, Owner of Tanpopo Japanese Food Ltd, commented, “After extensive trialling of another competing product, we chose the Panasonic solution because of its environmentally-friendly credentials.  Other key factors were the range’s reliability, the fact the units are compatible with a range of control systems and due to the low charge of CO2 required by the units, no additional leak detection equipment was necessary for this application.”   A further challenge for this installation was that the cooking and manufacturing process in the factory results in ambient temperatures of up to 43oC, so any refrigeration units chosen must be able to operate efficiently even in these extreme conditions. Fortunately, this is one of the unique benefits of the Panasonic units, which can operate efficiently at this temperature, and thus provides additional confidence in the technology of the product.   The Panasonic CO2 Cold Chain units are suitable for both refrigerated and freezer showcases, as well as walk-in freezers and cold rooms – offering a solution for all commercial refrigeration needs. The technology has been specifically developed for small to medium capacity applications within the retail and food service sectors. The range available in the UK features units for medium temperature (4kW to 16kW) and low temperature (2kW to 8kW) condensing units.  Additionally, the 16kW (10HP) units can be connected to provide up to 32kW cooling capacity at medium temperature.   Launched in Japan in 2010, the range has 10 years’ experience in projects within Japan and was first launched in the UK in 2018. The key benefits and factors to the success of the units is due to the reliability, the compact size, the unique two stage compressor, the easy installation and the use of the natural refrigerant CO2. Furthermore, the units are compatible with a range of different control systems.   In July 2019, Versan Ltd commissioned and has currently installed four Panasonic 2kW CO2 units at Tanpopo Japanese Food Ltd’s premises in Feltham that replaced four of the R404 systems, two in the low temperature cold rooms at -30°C and two serving as medium temperature chillers at -4°C.  Due to the advice from Versan Ltd and their experience of CO2, further units are due to be installed to replace all the current R404 systems at the premises.  Each of the Panasonic units is used to either freeze or chill the products produced in the sushi factory, that are then stored prior to them being shipped to supermarkets around the UK.   Xavier Debray, Managing Director of Versan Ltd commented, “One of the pre-requisites for many supermarket chains now is to review their supply chain and their green credentials, such as the use of renewable technology during their processes. The Panasonic units use CO2, a very attractive natural alternative to conventional refrigerant gases.   CO2 has a zero ODP (Ozone Depletion Potential) and a GWP (Global Warming Potential) equal to 1 (compared to a refrigerant like R404A with a GWP of 3922).”   Xavier has a keen interest in renewable and sustainable technology and in particular the use of CO2 and adds, “I studied the use of CO2 as a refrigerant some years ago when at University and was thrilled after recent research that manufacturers such as Panasonic are now embracing this technology and have developed a reliable commercial refrigeration range that uses CO2.  Some of Tanpopo’s partners are also Japanese and really liked the fact that the technology from Panasonic has originated and been proven in projects for over a decade in Japan. Furthermore, the unique benefit of the Panasonic range is being able to easily switch from either freeze or chill mode.”   Indy Tharnvithian, Technical Specialist for CO2 at Panasonic added “When installing the Panasonic CO2 range, just two settings are required – vacuum mode and evaporating setting – everything else is pre-set. Obviously if need be, settings can easily be modified with alarms that will indicate any wrong settings. If installers register on the Panasonic Pro-Club website, they will have access to free commissioning tools that includes a cooling capacity calculator, pipe calculator and EEV quick selection tool.”   Xavier further explained that, “As Versan Ltd were one of the first to commission and install the Panasonic units in the UK, we were originally a little bit apprehensive, but found that by working with Indy, Technical Specialist at Panasonic, onsite during the design and commissioning stage, plus throughout the process, helped to make the process easier. In fact, we were pleasantly surprised by how easy the units were to install and how reliable the units have been since installation. So much so that Tanpopo are looking to install further units.”

Burger and Lobster


Aquarea air to water heat pump, Restaurants



Panasonic’s air-to-water Aquarea system has been installed in the latest glamorous Burger & Lobster restaurant in Bath. The Octagon Chapel, a large listed building in the city centre, was converted to accommodate the restaurant, and Panasonic’s Aquarea system provided an extensive, energy efficient and unobtrusive heating and cooling solution.

Burger and Lobster has strict interior design guidelines to create an atmosphere that is relaxed yet luxurious, a comfortable environment for staff and diners. These guidelines do not allow systems such as the heating and cooling system to be obviously on show. With the added challenge of working in a listed building, Panasonic worked with distributor Oceanair and design and install specialists FWP to deliver an HVAC system that was not only powerful and efficient, but was also easy to install and could be concealed easily.  

The Octagon Chapel is a large, open space that has a high-ceilinged central area, which has been converted into the bar of the restaurant. It required a powerful heating and cooling solution to create a comfortable environment for staff and diners. Oceanair supplied the Panasonic Aquarea Monobloc air-to-water system, which offers high levels of efficiency and requires very little installation space, making it much easier to install than equivalent systems. The Aquarea heat pump was also chosen for its flexibility, as it can work well with a number of heating systems including floor standing units, low temperature radiators and even fan coil heaters.  

FWP used a range of units from Panasonic to subtly deliver heating and cooling into the restaurant. Floor standing chassis units were concealed behind partitions to avoid being seen, and ducted units and ceiling cassettes were discreetly installed above ceiling voids, to minimise the visual impact. Every component of the system was optimised to provide maximum efficiency and ensure that it did not impact on the interior design. This included the piping, which had to be designed and laid out very carefully so that it did not negatively affect the aesthetic.  

FWP were also able to use heat generated in the kitchen from cooking, to dramatically increase the efficiency of the system and generate huge energy savings for Burger and Lobster. The hot air captured by the kitchen extractor fan was used to pre-heat the water before it entered the Panasonic Aquarea air-to-water system, meaning the heat pump did not have to use as much energy to heat the water. The efficiency of the heat pump was further increased because of its positioning near the ice machine, as in winter it is able to use the warm air generated by the ice machine to heat water and provide heating in the restaurant.  

Control of the heating system is crucial in a restaurant environment, to ensure diners and staff are comfortable and neither too hot nor too cold. FWP specified Panasonic’s CZ-RTC2* controller, which enables sophisticated yet simple local control, so that restaurant staff without much expertise in heating and cooling systems can use it easily. The CZ-RTC2* allows employees to change the temperature, fan speed and air flow, as well as the operation mode. Straightforward control is essential to creating a comfortable environment in the restaurant, and ensuring that diners enjoy their experience.  

*Panasonic has recently launched its latest controller, the CZ-RTC4, which has a brand new interface and a wide range of features, making it easier than ever to create the perfect atmosphere.

Le Dolcezze Patisserie


VRF, Shops, Restaurants


The Panasonic PACi Elite range of semi-industrial systems has been developed to lead the way in quality air conditioning for commercial environments. The Elite line is prevalent in low temperature applications, including wine cellars, server rooms and food storage areas, thanks to its ErP-approved units, which boasts a SCOP A++ rating and exceptional cooling capabilities.   

It is thanks to this technology that the Panasonic PACi Elite range has been installed “Le Dolcezze", a patisserie in San Lazzaro, Italy.

Famous for its Neapolitan pastry, "Le Dolcezze" required a robust, high quality and reliable solution that would provide consistent heating and cooling on the shop floor, storage room and in the kitchen, where fresh pastries are prepared.  

The building previously featured a residential air conditioning system. This unit was unable to meet and maintain the required internal temperature of 15°C, which is vital to the storage and preservation of raw ingredients. As a result, during an exceptionally hot summer in 2015, the owner suffered major losses due to the deterioration of the quality of his products, in particular the chocolate, which was to be used in the preparation of fresh cakes.  

Installer, Mariani SRL, specified and installed the Panasonic PACi Elite range to provide a reliable, high efficiency and energy saving air conditioning solution.  

The existing interior unit was replaced with the Panasonic PACi Elite single split system, the ideal solution where there is a requirement for temperatures ranging between 8°C and 24°C. The single outdoor units offer cooling capacities from 4.9kW to 18.5kW and incorporate a dedicated “wine cellar” function. This feature has been developed especially for commercial or industrial applications, such as "Le Dolcezze", where maintaining a consistent, cool temperature is key.  

Additionally, the units incorporate DC inverter technology, minimising energy waste, and R410A refrigerant to reduce the unit’s CO2 emissions. The units are controlled via a Panasonic CZ-RTC5 remote control, enabling the user to monitor and maintain consistent air temperatures. This feature ensures that the owner is able to achieve the required indoor temperature to preserve the raw ingredients.  

Panasonic PACi Solutions

The Panasonic
PACi Elite range boasts a wide range of features that make it the perfect solution to the needs of challenging commercial and seasonal demands. Not only can the units provide continuous cooling, even when outside temperatures are as high as 46°C, they also provide heating when external conditions are as low as -20°C, and cooling when conditions are down to -15°C outside.  

Boasting exceptional energy performance, the system ranks among the best in its class (SEER A++ / SCOP A+) and its inverter technology reduces power consumption and operating costs by 20%. This, combined with the use of R410A gas to reduce the unit CO2 emissions, ensures Panasonic PACi solutions offer market-leading efficiency.  

The latest models in the series are not only built to the highest industry standards to ensure optimum efficiency, they are also lightweight. With a slim and compact design, these units are easy to install.  

CZ-RTC5 Control
The Panasonic CZ-RTC5 wired remote control is unique, due to its elegant design, its control of operation on demand and its display of live energy consumption. Operational information is shown on the built-in screen as images to facilitate the immediate understanding of energy usage. The text is available in five languages (Italian, English, German, French and Spanish), and the backlit display also makes it easily visible, even in the dark or in poor lighting. The main features of the CZ-RTC5 include the capabilities of timer programming, the selection of indoor settings, and the display of the energy consumption.

Monument Hotel

Barcelona, Spain

VRF, Hotels


Situated in a historic building on the elegant Paseo de Gracia in Barcelona, the 5-star Monument Hotel recently re-opened after an extensive renovation. This prestigious hotel had exacting standards when it came to the refit programme, including specific requirements for the building’s air conditioning system which needed to complement the impressive interior design.  

Barcelona-based installer,
IJT Instalaciones selected Panasonic’s ECOi VRF recovery solution thanks to its high performance heating and cooling, discreet installation and energy-efficient capabilities. 

The spectacular Monument Hotel, part of the Preferred Hotels & Resorts Collection, is housed in a neo-Gothic palace dating back to 1896. The hotel is situated in the heart of the city’s commercial, tourist, cultural and business hub, on the Paseo de Gracia – one of the most exclusive avenues in Barcelona.  

Its exterior boasts a colourful polychrome facade, one of the most artistic and impressive on Paseo de Gracia, created from a combination of materials including exposed brick, stone, ceramics and wrought iron. Inside, the blend of space and modernist elements, with an emphasis on light and texture, creates a fascinating interior, crafted by architects Oscar Tusquets, Carles Bassó and Tote Moreno in collaboration with interior designer Mercè Borrell.

The Monument has 84 exclusive rooms and suites, which vary in size from 24m² to 85m², designed to showcase the building’s breadth and luminosity thanks to high ceilings and large windows. The interior design of each room includes details of brickwork on the walls, oak flooring and furniture made with natural materials that provide great warmth, harmony and visual comfort.  

For the renovation project, it was vital that the air conditioning system could work in harmony with the hotel’s considered design, with fittings being discreetly disguised within the fabric of the interior.  

Luxurious comfort with maximum efficiency
IJT Instalaciones worked closely with engineer, RF2 Enginyers, to install Panasonic’s ECOi VRF air conditioning system to service all of the hotel bedrooms across five floors. Designed to offer total comfort for guests, the ECOi VRF system is ideal for large commercial projects thanks to its adaptable design and energy saving attributes. The ECOi VRF also offers simultaneous heating and cooling capabilities, which saves both energy and costs, as warm air generated during operation can be extracted and distributed to other areas of the hotel for heating. This eco-friendly transfer of heat also supports the hotel’s overall sustainability objectives.  

Moreover, the
ECOi VRF outdoor units are very compact at just 1m² per unit and requiring only 10cm between each unit, taking up just a third of the space of a conventional hydraulic system. This is especially beneficial for a hotel such as the Monument, which is located in a busy city centre location where external space is at a minimum. The total exterior installation included four ECOi outdoor heat pump units and 12 ECOi VRF outdoor units with heat recovery.  

Internally, each hotel room has been installed with ultra-slim M1 variable static pressure units, which have an extremely quiet sound level of just 25dB. These thin and discreet units have been installed within the very narrow false ceilings, so as not to interfere with the interior.  

In the rest of the building, where the ceilings are quite low, concealed floor-standing R1 units have been installed within perimeter areas to provide powerful and effective air conditioning. The R1 units have been fitted without enclosures, so that they are completely concealed within the existing decor.  

Intelligent control system
The hotel’s air conditioning is managed with Panasonic’s intelligent hotel controller system, which allows independent in-room temperature regulation, while also being connected to the hotel’s reception for greater efficiency and control.  

A single digital thermostat located in each room allows guests to manage both the indoor air-conditioning unit and bathroom floor heating. The controller can also be pre-set with minimum and maximum temperature levels and specific scenarios such as ‘vacant’, ‘occupied’ or ‘day’ and ‘night’.  

While the hotel rooms appear to be controlled by a simple, conventional digital thermostat, the complete system is much more complex. The in-room thermostats link to a KNX internet cloud control system via a Panasonic CZ-CFUNC2 adaptor, centralising overall control of every thermostat. With this centralised management system, facilities and building managers can monitor energy usage throughout the hotel and maximise efficiency and cost-savings.

Another element that can be integrated into the KNX cloud control system is the room reservation system. With this feature users can define different room statuses, for example "quiet room" and "room not booked". Combining this information with the status of "room occupied" and "unoccupied room" through key card intelligence, users can define a table of settings for each of the situations allowing them to further optimise comfort and savings.  

At the Monument Hotel, Panasonic has delivered a sustainable and cost-effective solution through a winning combination of high-performance air conditioning and intelligent cloud control. The complete installation not only provides long-term cost and energy savings, but also discreet fittings that blend seamlessly into the hotel’s beautiful interior design.

Distributor Logicool provided the Panasonic ECOi and ECO G systems to IKEA and worked with Wolverhampton-based TSG Electrical Services to ensure an efficient, cost effective installation that met the client’s objectives.  

“The IKEA project in Birmingham was a very exciting opportunity for us,” says Karl Richardson, MD at Logicool. “The store needed a heating and cooling solution delivered on a tight budget. Panasonic’s ECOi VRF and ECO G systems were essential to the success of the project due to their reliability and efficiency; reflecting the high standard of quality held by IKEA and their suppliers. It was particularly refreshing that - despite the tight project budget - IKEA worked with us and TSG Electrical Services to ensure that the quality of the solution remained high, rather than making cuts to the specification, which happens all too often on projects both large and small.”  

The “Click and Collect” store is a new concept that IKEA is rolling out across the country. The Birmingham Central store is the second example of the new format, located on the former site of Toys R Us in Dale End. The building was approaching the end of its practical life, and is expected to be demolished in the next four years to make way for improvements to Birmingham city centre. Such a short term lease was ideal for IKEA to trial a new store concept, however it meant that the budget was restricted. The additional challenge of working in a city centre environment was the limited electrical power supply, meaning the site did not have sufficient power to deliver heating and cooling - via an electric VRF system - to both the front-of-house retail area and the back-of-house office.  

Panasonic’s ECO G technology was crucial to the success of the project. Logicool supplied two of Panasonic’s gas fired ECO G heat pumps to provide heating and cooling to the front of house retail areas. With a COP of 1.25 and EER of 1.15, Panasonic’s ECO G heat pump delivers a greater efficiency than traditional gas-fired systems. The ECO G’s utilise the on-site gas supply which meant Logicool were able to deliver the ideal environment for shoppers with minimal additional demand to the electrical power supply.  

Logicool supplied 16 of Panasonic’s innovative U1 type 4-way 90x90 cassettes. These units boast an improved noise performance, providing a more comfortable and relaxing atmosphere for staff and shoppers. The shallow and unobtrusive profile of the cassettes ensures that they can be installed discreetly into the retail area and do not distract customers from the products on the shop floor. Logicool and TSG Electrical Services reduced the number of indoor cassettes but increased the size of the fan coils. This ensured that the system provided a consistent and comprehensive heating and cooling solution without exceeding IKEA’s budget.   
In the staff offices and the collection & returns areas, Logicool used Panasonic’s ECOi VRF system to supply heating and cooling, to create a comfortable, climate-controlled environment. The electric-powered VRF system is extremely efficient, achieving a SCOP 6.33 and SEER of 8.06. In the back of house areas TSG Electrical Services also installed the reliable U1 type 4-way 90x90 cassettes to provide heating and cooling. Panasonic’s new Heat Recovery Control Box was used to further increase the efficiency of the system, accompanied with the CZ-RTC4 controllers to give staff the ability to fine-tune their environment and ensure that energy is not wasted through unnecessary operation.  

Panasonic’s advanced heating and cooling technology was an essential component to the project. Panasonic allowed for an innovative, comfortable environment for shoppers and staff, while overcoming technical challenges and budget restrictions through close collaboration with Logicool and TSG Electrical Services.

Marina Village Greystones - Ireland

Aquarea air to water heat pump, Residential


Marina Village Greystones in Ireland is a new development by Bridgedale Homes that features 358 architecturally designed A-rated homes (205 apartments and 153 houses) in a stunning seaside location. Bridgedale Homes tasked Heat Merchants, the national heating, plumbing & renewable energy specialist with designing and supplying an energy efficient heating and hot water solution to each home. The Panasonic High Temperature Monobloc Aquarea air source heat pump was specified because of its phenomenal A++ energy efficiency rating, low running costs and ease of installation.   

This project has resulted in Heat Merchants winning a Panasonic PRO Award for the second time in a row, as it was recently awarded Best Residential Project, alongside Bridgedale Homes.

Shane Duffy, National Commercial Heating Manager for Heat Merchants commented “we are delighted that the Marina Village project has been selected for this award. The Heat Merchants technical team worked closely with our clients Bridgedale and Delap & Waller consultants, to provide an excellent heating solution that will be efficient, low maintenance and provide high levels of comfort for the residents of these fantastic houses.

This project showcases excellence in overall heating system design using the latest technology from Panasonic to achieve A rated homes.” “Our vision for the Marina Village Greystones development was to provide the very highest quality of living,” says Tony McLoughlin of Bridgedale Homes.

“Energy efficiency was a key part of this. We wanted the most advanced heating and hot water technology that would ensure low energy bills for our residents while providing the very best solution to deliver maximum comfort. Panasonic’s Aquarea air source heat pumps exceeded every requirement that we set, and we know that homeowners who have already moved in are delighted with the solution.”  

The Panasonic High Temperature (HT) Aquarea heat pump was paired with a pre-plumbed, combined 200 litre cylinder and 70 litre buffer tank for hot water storage, providing the residents of the Greystones development with constant heating and hot water all year round.

The system was chosen by the designer because of the expertise and technical support that Panasonic provides, as well as the reassurance that the Aquarea system delivers hot water at a constant temperature of up to 65°C without the need for a back-up system.  

Due to the close proximity to the Irish Sea, and the unique environment of its beautiful coastal setting, Panasonic’s heat pumps needed to be protected against the corrosive effects of the high levels of salt in the air. Each system was therefore treated with a special coating developed by Bronz-Glow that provides corrosion protection and can reduce energy consumption to ensure longevity in terms of performance, maintenance and aesthetics.  

The heat pumps were sized using a combination of Panasonic Aquarea Designer software and Heat Merchants Technical Design software to help achieve the overall A-rated Building Energy Rating certificate. The Aquarea system features a multiple zone heating and thermostatic valve control system for all radiators in the homes to help provide ultimate comfort, ease of controls and exceptional energy efficiency for its residents.  

A resident on the Greystones development, Stephen Kavannah commented: “We have found at least a 50% decrease in our overall fuel bills since moving into the Greystones property and found the system to be efficient and reliable.  We would highly recommend the Panasonic Aquarea air source heat pump.”  To watch a video on this project, visit the Panasonic Aquarea profile on

When online fashion brand Zalando required a sustainable, energy-efficient cooling solution for its 19th century warehouse office conversion at Grand Canal Quay, Dublin, FKM Group selected the Panasonic 3-pipe ECOi MF2 AC solution to be installed by Crystal Air. The project needed to be completed with minimal changes to the fabric of the building, with fresh air delivered using ERVs located in the roof space of the building. FKM Group selected Panasonic because they could provide “a highly efficient integrated fresh air and AC system, coupled with the high standards of Crystal Air for the installation”, commented Bob Gallagher, Operations Director of FKM Group, “especially important as all the components are visible”.
The project resulted in Crystal Air obtaining the ‘Special Recognition’ award in Panasonic’s prestigious PRO Awards.
The Panasonic VRF ECOi MF2 solution offers a compact space-saving design and low noise levels thanks to a uniquely constructed casing comprising of two compartments; the upper chamber which contains the heat exchange and the lower chamber to store the compressors.  Additionally, the system allows for a non-stop operation during maintenance.
Ducted units have sufficient fan power to drive warm air from the roof of the warehouse building to the floor, with minimum noise disruption for this large open plan office environment. “The Panasonic MF2 range coped brilliantly” added Domnick Ward of Crystal Air.
The Energy Recovery Ventilator (ERV) of the MF2 system recovers 77% of the heat in the outgoing air, to deliver a more ecological and energy efficient building with the air conditioning load being reduced by approximately 20%, thus resulting in significant energy savings overall.
During the summer months the system allows for a purge during the night, allowing the cooler night air to be present for a fresh start to the day. Adding to the efficiency of the system, the number of ERVs running at any one time can be reduced depending on the number of people occupying the space, for example, during lunch times.
The system has a centralised controller that acts as a master scheduler, allowing full management of the entire space. In addition, each area within the space is fitted with ECO NAVI detectors to automatically reduce the energy consumption when rooms are unoccupied.  User -friendly remote controls have also been fitted to give individuals the option to instantly adapt settings to suit.
Bob Gallagher further mentioned “We have been delighted with the level of support provided by both Panasonic and Crystal Air prior, during and after the project with our client Zalando being delighted with the end result”.

Hotel Atocha

Madrid, Spain


The ‘Only You Atocha’ features an original interior design, created by Lázaro Rosa Violán, creating a modern and comfortable space for travellers and locals, in the Atocha Square, Madrid. To provide air-conditioning to this iconic hotel, Panasonic has installed 7-unit ECO-G systems and a wall-mounted PACi Standard and Elite Inverter+ Kit in the basement. This project was recently awarded Best Innovative GHP Technology Project in the Panasonic PRO AWARDS. Madrid’s new hotel ‘Only You Atocha’, recently opened by the Palladium group, is benefitting from Panasonic's efficient solutions for its air conditioning.  The hotel has 206 rooms and a team of more than 60 people, and the system installed comprises seven Panasonic ECO-G U-30GE2E5 systems and a Kit KIT-60PKY1E5A for the basement.
The interior of the ‘Only You Atocha’, located in front of the Atocha station in Paseo Infanta Isabel, is an installation by Lázaro Rosa Violán of a modest aesthetic mix, featuring cultural influences from around the world but creating the perfect balance between form and function.  This unique hotel’s iconic style has been created by the interior designer by strategically placed scenarios featuring furniture from different eras and styles throughout.
As well as being a stylish setting, the hotel’s ambience is so comfortable thanks to the Panasonic air conditioning system.  So much so, that this beautiful project has resulted in Lázaro Rosa Violán winning a Panasonic PRO Award for Best Panasonic Innovative GHP Technology Project.
The ‘Only You Hotel Atocha’ has 206 rooms distributed over seven floors: 114 Deluxe, 78 Premium, 12 junior suites and 2 suites, as well as a terrace completely designed and equipped to surprise and relax.
Additionally, the hotel has several inspiring spaces such as the ‘Mama Framboise bakery’, a bakery in the purest New York style along with the restaurant ‘Trotamundos’, offering fusion cuisine in a cosmopolitan decor that follows the influence of the Big Apple.  And finally, ‘You Universe’ located on the seventh floor of the hotel has a large terrace and panoramic views of the city where guests can have a drink and enjoy the DJ’s live music sessions.
A project adapted to the needs and layout of a building that also sought to achieve maximum energy efficiency
This building with 13 floors (4 basements, ground floor, 1st to 7th floors and roof terrace) required a power solution of 838kW in cooling and 698kW in heating set by the engineer’s calculations. These values ​​correspond to the hotel’s demand peaks, which can occur on certain summer and winter days respectively.  For intermediate periods (such as March-May and September-November), demand was anticipated to be perhaps 70% lower than the summer and winter maximums. The engineer responsible for the project, the engineering department of El Corte Inglés, opted for a base solution of seven Panasonic GHP units, fed by natural gas with each connected to a hydrokit for production of hot and cold water at temperatures of 7°C / 12°C and 48°C / 43°C respectively, since the air conditioning is performed by indoor fan coil type units.
The demand for cooling by the GHP units is 469kW and heating of 560kW. The remaining power to cover the total demand of the building is realised with a traditional system of chiller and boiler respectively.
The production of hot and cold water for cooling and heating is turned into separate heat and cold collectors, completing the installation to four pipes with their corresponding hydraulic system, pumping groups, valves and fan coil elements.
The building control system determines whether heating / cooling must be covered by the gas, chiller or boiler heat pumps. The above is dependent on a series of external conditions so that the performance of the installation is optimised, controlling the cascade entry of the gas heat pump units, thus ensuring maximum energy efficiency for the hotel.  In spring and autumn, half of the units will easily work in cold mode (with the subsequent use of a large amount of residual heat), while the other units work in heat mode.
Waste heat utilisation for free ACS generation
Thanks to the Panasonic GHP equipment, the recovery of residual energy from the exhaust gases and the cooling of the engine to preheat the ACS deposits of the hotel are used.  Peak energy recovery occurs when all gas heat pumps work at 100% demand in cold mode. The energy recovered at that moment reaches 30kw per unit, delivering hot water to temperatures between 70ºC and 75ºC. Panasonic’s extremely efficient system is capable of delivering very good results for ‘Only You Atocha’ hotel.  It has been estimated that the residual energy of the equipment can recover up to 82% of the energy needed to meet the hotel's demand for ACS. In principle, water is preheated with residual energy.

NHS Canford House Clinic

Bournemouth, UK

Domestic air to air heat pump, Commercial, VRF, Public buildings


Located in Bournemouth, Canford House is a fully managed office space, leased by the Dorset Clinical Commissioning Group (CCG). The building owners, St Modwens PLC (recently sold to Biz Space), were in desperate need of an updated air conditioning and heating solution that was cost effective. The building utilised an old chilled water system, operating on R22 refrigerent that was at the end of its life, paired with an old boiler, both working 16 hour days, in addition to the inconvenience of one of the two compressors failing on a regular basis and proving very costly. The building was in urgent need of a long term solution.
To fullfill Canford House requirements, a Panasonic VRF 2-Pipe Mini ECOi 6 series in addition to a Panasonic Aquarea-Pro 50 kW was installed by Woodhouse Environmental Services to provide precise temperature control, low energy consumption and the inverter range for greater overall efficiency. The Panasonic Aquarea-Pro 50 kW was installed to work with extreme temperatures and provide a clean, safe, economical and environmentally friendly solution.
Trevor Woodhouse of Woodhouse Environmental Services Ltd, commented “As the CCG had to stay operational during any work, it was important for the installation of a new system to have minimum impact on the day to day running of the property, to fit into a specific small space, be energy efficient, work with existing units and be installed quickly.“
The NHS CCG is one of four organisations occupying the building, which  at the time was owned by St Modwens PLC who contacted installer, Woodhouse Environmental Services Ltd, who had previously installed 12 Panasonic VRF systems onsite, to other parts of the building, five years previously. St Modwens were more than happy with the energy effiency and cost savings that these now provided and wanted an integrated system to help reduce the cost of servicing and maintenance.
Given the many challenges outlined above, as well as 75% of the building having been previously redeveloped in 2011, this effectively leaving a 200 kW chiller servicing 40 kW of cooling. The original heating system was also from an existing inefficient boiler connected to perimeter radiators.
It was decided to avoid simultaneous use of the system for heating and coooling as previously this had caused large energy inefficiencies. The solution needed to allow heating and cooling as and when required, but not opearable at the same time.
The new solution included a Panasonic Aquarea-Pro 50kW and a Panasonic VRF 2-pipe ECOi system which provided the building with very high SEER and SCOP figures to minimise the energy bills for Canford House with the help of Panasonic distributor ESS.
The Panasonic VRF 2-Pipe Mini ECOi 6 series is an outdoor unit specifically designed for demanding applications. This unit also utilises R401A and DC inverter technology.

Grade II 17th Century Barn renovation

Essex, UK

Aquarea air to water heat pump, Residential


Panasonic Air Source Heat Pump efficiently heats Grade II 17th Century Barn renovation   The restoration of a Grade II listed 17th Century barn in Broxted, Essex ably demonstrates the strengths of Panasonic’s Aquarea air source heat pump by   supplying hot water and heating to the stunning property via under floor heating. Energy specialists, Eco Installer, completed the installation of two 16kW Panasonic Aquarea T-Cap three-phase heat pumps.   Featured on Channel 4’s “The Restoration Man with George Clark” programme, this 17th Century barn that was originally used for storing and threshing of crops and now renovated to a residential family home was a complex project, as Roland Gurner of Eco Installer explains: “This was a major restoration project, with the client looking for an alternative to an oil or fossil-fuel based system, a 4,000m² agricultural barn featuring high ceilings with performance and efficiency being key to a successful specification.  The two 16kW Panasonic T-Cap heat pumps were chosen as a perfect solution for the large internal areas and to provide a reliable and efficient source of heating. The property already had three-phase power installed with the units working well as a cascaded system, being highly efficient and providing energy when needed. Not only that, but we had to accommodate the filming crew, and work around their schedules.” The Channel 4 programme highlighting the initial build was first aired in Autumn 2017.   Barn-storming challenges… The Barn was originally owned by and part of the nearby St Mary’s Church Estate and built in the 17th Century for storing and threshing of crops such as wheat, which required very high ceilings and sloping floors for drainage, with large, tall doorways to accommodate stacked horse drawn carriages riding into the building. The property had not been used for some time prior to the current owner Jude McKelvey purchasing it in 2014 with the aim to renovate the property to a residential family home.    The roof structure needed repairing and the original beams required strengthening with some of the old timber having to be replaced – after a long planning and approval process, work finally began in March 2016 and the roof installed – it took eight weeks, four roofers and 44,000 roof tiles (many being reused from the original building).  It took a further 16 months before the heating system was installed and the Barn ready for occupation.   The new owner, Jude McKelvey, had a dream to renovate and convert the abandoned barn into a domestic dwelling for herself and her two sons to live in. She was heavily involved in all decisions, including the provision of heating and hot water, as Jude comments: “I was looking for a reliable, efficient and cost-effective heating solution for the barn, but one that also didn’t detract from the beauty of the amazing building.  Also, we wanted to avoid having to install an oil tank, and therefore looked for a system based on renewable technologies that would also keep our running costs down for heating such a large space. We were pleased to work with the team at Eco Installer to advise on the most appropriate solution and then design and install the air source heat pump system.”   Renewable energy, plumbing and heating specialist, Eco Installer, provide plumbing, heating, renewable energy and ventilation services in Cambridgeshire. The team headed up by Roland Gurner includes heating and plumbing professionals with extensive knowledge and experience of mechanical and electrical engineering, renewable energy and technical consulting services.  As such, they were able to take on this demanding project and devise a system to deliver its complex requirements.  The challenges for the installation of the heat pumps was that the structure was large with the beams of the whole building exposed and open plan, everything was visible, (beams/structure etc), therefore the neatness of the installation was critical to the project. Sizing the heat pumps, carrying out heat-loss calculations were all a challenge as the barn was very large, old, and ventilation changes were unknown.    Tony Holland from Oceanair, the distributor of the Panasonic system commented, The Panasonic Aquarea T-Cap was the ideal solution for such a large renovation project, as the system provides a reliable and constant nominal capacity output and excellent energy rating with a COP of 5.08. The quietness of this system was also a deciding factor on selecting this product. As well as being a reliable and efficient heating and hot water solution against alternatives such as boilers and oil burners, this Total Capacity system maintains heating capacity, even with cold outdoor temperatures, maintaining 16kW of heating, even when outside is as low as -15oC.”   Tony further mentioned “This project also gave us the chance to continue our excellent and important business relationship with Eco Installer on such a unique and iconic property and we are delighted with the result.”   Panasonic’s Aquarea is a reliable, sustainable, intelligent and extremely efficient heating and hot water solution compared to alternatives such oil-fired burners or gas boilers.  The Aquarea T-CAP (Total Capacity) maintains heating capacity, even when the outdoor ambient temperature is cold – maintaining 16kW of heating down to -15°C outdoor temperatures.   Sean Graham – Area Sales Manager at Panasonic further added “The Panasonic Aquarea T-Cap system was selected for this project because of its ability to operate down to low temperatures and still maintain full capacity, even at -20°C”.   Jude concludes: “Working with Roland at Eco Installer, we were delighted to find the Panasonic Aquarea T-Cap.  Having now experienced our first cold winter we found that the heating solution installed kept the barn at a comfortable temperature throughout – and we had no surprises when it came to the fuel bills.”

Suffolk, UK

Domestic air to air heat pump, Commercial, VRF, Public buildings, Others


Skyliner Sports Centre, located in the Moreton Hall area of Bury St Edmunds in Suffolk, required an energy efficient and cost-effective air conditioning solution to be installed into their new building that houses their busy gym and fitness studios. There is a limited supply of power to the building which is why three Panasonic GHP (Gas Driven) VRF units were chosen as the ideal energy efficient heating & cooling solution for this project by installers Pitkin & Ruddock and distributor Oceanair. Damian Nunn, Director of Pitkin & Ruddock went on to explain, “The main challenge for this project was the restricted amount of power allocated to the building, in this case on 200A TPN, which is not enough to accommodate a conventional VRF air conditioning system, as well as to maintain the other essential building services such as IT and lighting etc. The Panasonic GHP VRF units overcome this problem as they can operate on a lot less power, as it is only the fans and control circuits which draw on the power supply.  The technology also ensures the system is also highly energy efficient.”  The gym area and each fitness studios on site has a separate Panasonic GHP VRF system installed complete with four to six Panasonic ceiling cassette units. Whilst the cassette units are in use, fresh air is brought into the areas and stale air is removed via Panasonic heat recovery ventilation units. Damian added, “The heat recovery ventilation units recover up to 77% of the heat in the outgoing air making for an ecological and energy efficient solution for this project.” The gas engine within the Panasonic GHP VRF units is used as a driving source of the compressor instead of the usual electric motor, this provides the advantage of waste heat being produced from the gas engine and being available to use elsewhere, thus freeing up the electricity supply for other uses. Furthermore, the system provides advanced all-round energy efficiency and is a very cost-effective solution for simultaneous heating and cooling. Tony Holland, Account Manager from Panasonic distributor Oceanair added, “The unique Panasonic GHP VRF units are a natural choice for commercial projects with a limited supply of electric power, in addition to being able to meet and deliver high demands quickly and efficiently. This product suited this project perfectly. Furthermore, this project also gave us the opportunity to continue our excellent business relationship with Pitkin & Ruddock, and as a Suffolk resident myself, it was a pleasure to work on a local project of this nature with such a respected local company.”   The Skyliner Sports Centre is located within the grounds of a busy school, with the gym and studios being in constant use. The gym has been designed with comfortable spacious areas to accommodate the high quality 45 stations of equipment and overlooks the swimming pool. The equipment includes cardiovascular, resistance, functional training equipment and free weights. Kate Crouch, Centre Manager of Skyliner Sports Centre added, “Our Studios and large gym with 45 stations at the Skyliner Sports Centre are incredibly busy with our members being very appreciative of the new air conditioning system to keep them cool whilst using the facilities. Members are consistently satisfied and enjoy the perks of a great air-con system. Communication with Pitkin & Ruddock has been really easy, in addition to them providing a great service throughout our first 12 months.”

One of the main challenges for data centres is coping with cooling and humidity control demands within the building because of the enormous heat gains generated by the large volume of computers and lighting systems – often in operation 24 hours a day, seven days a week.   In the case of Concentrix Customer Engagement Centre in Belfast, there was also the added complication of the number of employees on site approaching close to 1500 people. Belfast-based Aircon Sales and Service, which designs, supplies, installs and maintains various air conditioning solutions, recently installed a combination of Panasonic GHP VRF 3-pipe, 2-pipe and Split Hi Wall type units to heat and cool the 130,000 sq ft, three storey property at the Concentrix Call Centre in Belfast.  The installation at Concentrix was a very complex and challenging project due to the building’s design and lack of available electrical supply to the site. In addition to the nature of Concentrix’s business, which requires a significant power load for the operations of the building including lighting, computers and servers, the property also needed to provide comfortable conditions for the 1500 employees on site. The team at Aircon’s contracts department, headed up by Manager, Stephen McGarry, worked closely with consultants Beattie Flannigan and mechanical contractors, Harvey Group, to deliver the best possible solution that site conditions would allow.  Ian McFerran, Aircon’s Managing Director explains, “Quality underpins our entire delivery model, with professionalism and attention to detail being the primary focus.  Coupled with competitive and cost-effective pricing, the overall package we deliver sets us apart from other market players.” Due to the design of the building which features low ceiling heights on each floor, the team devised a solution based on a larger quantity of indoor units operating at lower capacities. Not only that, the Panasonic DX gas-fired system provides close to 1.2MW of cooling, using between 20kW and 25kW of electrical input, thus efficiently providing optimum cooling for the building whilst only drawing a minimal load from the buildings electrical power supply.  The equipment specified included the following: ·         13 Panasonic GHP gas heat pump 3-pipe outdoor units ·         5 Panasonic GHP 2-pipe VRF outdoor units to service AHU DX Systems ·         155 Panasonic VRF cassette indoor units to serve all call centre and meeting room areas ·         19 Panasonic Split Hi Wall systems to serve various small UPS and comms rooms ·         Panasonic centralised and full Modbus BMS control ·       Panasonic Air Off Control employed in all call centre area’s to provide a very high sensible heat      ratio, 90%+ ·         All indoor units were sized to meet duties at medium to low fan speeds This project benefits from a sophisticated solution offering high performance, is cost-effective, energy efficient and 100% reliable.  The team involved worked collectively to supply, design and deliver the perfect solution which saw a seamless installation and subsequent commissioning.

Panasonic provides quiet efficiency to luxury homes

Chorley, UK

Aquarea air to water heat pump, Residential


A team from The Energy Centre North West has installed Panasonic Aquarea T-Cap heat pumps to provide energy efficient and cost-effective heating and hot water for The Kem Mill, Primrose Development of nine high quality homes in Whittle-Le-Woods near Chorley. The new Primrose Development at Kem Mill comprises nine luxury four to six-bedroom residential homes. The properties required a suitable solution to heat the homes as well as provide hot water. The specified requirements for the solution needed to be from a renewable energy source, yet also reliable, aesthetically pleasing, quiet, energy efficient and cost effective for its residents. The Panasonic Aquarea T-Cap air to water heat pumps was recommended as the best solution to meet all the above criteria.
Each home has been installed with underfloor heating on the ground floor and radiators in the upper floors and all are powered by Panasonic Aquarea T-Cap renewable heat pumps.
Mike Critchley, resident of one of the four-bedroom homes on the development commented “Over the last 12 months we have seen a 35% decrease in our energy bills compared to our previous similar size four-bedroom home but with less bathrooms and a combi gas boiler. We were one of the first to move into the new homes at Kem Mill and have now been resident for 12 months. I was dubious at the beginning about the air to water heat pumps but have been very impressed. We have underfloor heating in all areas of the ground floor and radiators on the upper floor with four en-suite full size bathrooms plus a downstairs toilet – there is always hot water in each with no complaints when more than one bath or shower is in use at the same time.”
The Panasonic T-CAP air-to-water heat pumps are part of the Aquarea H Generation range and benefit from the latest Panasonic heat pump technology. The units are controlled via the new Panasonic H Generation controllers. During operation, the controller provides time-switch programs for comfortable all year-round heating. In addition, thanks to the display of the current COP, the residents can always see how effective the system is in real-time.
Mike further added “Having seen extreme temperatures in March 2018 of -6oC, the system coped very well. The house is set up into seven zones, each with its own digitally operated thermostat controller within the room where we have set an indoor temperature to be 21.5oC, this was maintained during the cold season.”
Ivor Farnworth, Managing Director of Primrose Developments further explains “This is not the first time we have installed the Panasonic Aquarea T-Cap heat pumps into one of our developments. We first came across the Panasonic air to water heat pumps when we were converting four high end barn conversations during 2017 and researching energy efficient renewable solutions. We looked into several systems but found the Panasonic Aquarea T-Cap heat pumps to be very quiet compared to its competitors, aesthetically pleasing and have been impressed with the performance of the product in addition to the level of service and maintenance provided from the Installers at The Energy Centre.”
Chris Ingram, Director of The Energy Centre North West comments on the main benefits of the Panasonic Aquarea T-Cap “the units are super quiet which was a high priority during this project and thus allows them to be closely positioned to the properties where sound levels as low as 50 dB(A) are retained. The sound reduction in the units has been achieved with sound-absorbing materials that are commonly used in vehicles and computer systems. Panasonic’s three-blade fans also contribute to the model being particularly quiet. Furthermore, the units have an energy COP rating of 5.03* and can operate in temperatures as low as -20oC.  Additionally, as a specialist trained installer for Panasonic, we can also provide customers with a seven-year warranty on the units”.
Mike Critchley added “the outside units are placed behind the garage, are unobtrusive and very quiet. We have been very impressed with the unprecedented attention to every detail of the Primrose development. The installers at The Energy Centre have been approachable and amenable during the installation process and for on-going maintenance of the system”.

Stay Close and Cosy to Nature with Panasonic & the Dome Experience

Belfast, Ireland

Aquarea air to water heat pump, Others


The team at Panasonic have been working in collaboration with architects, engineers and local crafts people to create an unfiltered, unique and comfortable luxury living experience in bubble style Domes to bring a 180-degree transparent window to the world of nature. Michael Beare of Finn Lough Resort is the visionary behind this unique holiday experience.  He explains: “Our aim was to be able to offer holidaymakers a truly unique experience in this glorious setting, yet with minimal impact on these wonderful surroundings.  We aimed to minimise the footprint of the domes, offering off grid power and heating solutions, minimal construction requirements and a design that blends into the landscape.” Each Dome is kitted out with Panasonic Aquarea Fan Coils which are connected to air to water Panasonic Aquarea Monobloc heat pumps for quick reaction heating and cooling as well as domestic hot water.  Panasonic additionally supply DX ERV units to maintain a constant air flow rate. Furthermore, each Dome can be monitored via the Panasonic Aquarea Smart Cloud technology to maintain the optimal environment for each guest. Michael shared his original dream for the Domes: “I wanted to create a unique environmental experience where people can enjoy all the different elements of nature from a safe environment in a bubble of peace and tranquillity – I believe we have now achieved this.” The first Domes were created in 2015 but had several challenges such as misting up, being cold in winter and too hot in the summer months. Michael then started discussions with Panasonic to understand and solve these issues.  With continuous prototyping and testing, the team has since adapted and improved the Dome’s comfort and experience for guests.  Walter Stephens of Panasonic Ireland added “We are delighted to be part of this exciting and innovative project. The Panasonic Aquarea Mono-bloc air to water heat pump is an ideal, energy efficient solution, to heat or cool the Domes. The units have the added benefit of using the outside air and passing the air over refrigerant-filled coils (like a refrigerator). The then captured heat is automatically transferred to water, which is then ready for use in the heating or cooling system within the domes and for supplying hot water.  Furthermore, the units do not require access to mains gas.” The Panasonic Aquarea heat pump technology was chosen for this project as the units easily adapt to extreme low temperatures (-20oC) and high temperatures, whatever the climate.  The units are highly energy efficient (COP of 5.08), are compact, positioned externally to save on internal living space, quick and straightforward to install. The Domes are proving popular, with seven initially installed at the Finn Lough Resort in Northern Ireland which has recently increased to 14 Domes due to the high demand. Visitors’ feedback is highly positive, so much so that the resort now has an ever-growing waiting list. Each dome has a unique four poster bed, ensuite bathroom, nespresso coffee machine, fluffy robe and daily breakfast included and reside in the middle of a private forest. Visiting guest, Ainhoa Barcelona from Hello Magazine commented “Each dome has been fitted with underfloor heating and a boost button by the bed that can give you a blast of heat at intervals. This is glamping taken to the next level.” Another recent guest commented on trip advisor “I don't know where to start, Finn Lough was incredible! We stayed in one of the Bubble Domes and it was the most amazing experience. Before going I was slightly worried it would be cold, however, it looks like they have fully listened to feedback as it has heated floors, a heater and a heated mattress. Privacy never felt like an issue and we were blessed with a clear night with an incredible view of the stars.” Enthusiasm for the Dome experience has now reached a global level with orders for more Domes in remote locations coming from Australia, North America, Italy and France to name a few.

Lingfield Point


Commercial, VRF, Offices



When Capita, the business process management and outsourcing giant, decided to establish their new call centre in the Lingfield Point business park, it was important sustainability play a key role in the refurbishment. This included the heating and cooling system, for which M&E consultants Quinnross specified an energy efficient Panasonic system with advanced control technology.

Lingfield Point was originally constructed in 1946 as a wool production facility and now serves as a centre of business and innovation in the North West, with over 30 companies and organisations based there. Capita opted to convert one of the original large warehouses to a modern, high-tech call centre accommodating 500 staff.  Quinnross had already installed a GHP system in another project at Lingfield Point with great success, winning a number of regional and national awards, so when it came to designing a heating and cooling system for the Capita call centre the choice was easy. Working with distributor ESS, Quinnross specified the Panasonic ECO G 3 way system, which would take advantage of the abundant gas supply on the site, and is renowned for its energy efficiency and ease of installation.    

We completed a fantastic project with the Panasonic GHP system a few years ago and, with Capita’s focus on sustainability, we thought this was a great opportunity to use the technology again,” says Derek Quinlan of Quinnross. “Panasonic’s ECO G gas heat pump really ticks all the boxes for us, it’s easy to install, very powerful and is also really efficient.”  

Panasonic’s ECO G 3 way system uses gas, instead of electricity, to provide the power to draw in air and generate heat. This greatly decreased the load on the electricity supply at the Capita site, allowing it to be used for other essential systems that had to be installed to make the call centre a modern, technologically advanced facility. The ECO G 3 way can also be powered using LPG, meaning that if there were ever an interruption to the main gas supply, the units could still function. The demand for electricity for heating and cooling is reduced further by the ECO G 3 way’s use of a DC motor, which lowers the power consumption of the unit.

Capita is planning for 500 staff in their call centre so they required a system that could accommodate several different requirements at the same time, and also cope with a high level of demand for heating and cooling. Quinnross therefore specified 11 of the Panasonic ECO G 3 way units, which can provide heating and cooling simultaneously, to be installed to ensure the required system capacity and to connect to as many indoor units as possible. By installing over 150 indoor units in meeting rooms and open-plan areas Quinnross enabled accurate local heating and cooling, because groups of the units can be controlled individually, which creates a more comfortable environment for employees by adapting the system to their requirements.

Quinnross specified a comprehensive control system to increase the efficiency of the heating and cooling system. 11 wired timer remote controllers were installed to regulate operations of the ECO G 3 way units, and control air flow direction, temperature and fan speed. Panasonic’s intelligent touch screen controller, the CZ-256ESMC2, was also installed to interface with the site’s BMS. It combines the functionality to programme a schedule of operations, control factors such as fan speed, temperature and operation with the ability to control 256 units, which was absolutely vital in a project of this scale. The CZ-256ESMC2 also allows different levels of prohibition so employees can be given permission to change certain settings, such as temperature, but not others, like operation mode, preventing the system from being tampered with resulting in inefficient operation.  

With the Panasonic ECO G 3 Way system installed, Capita have ensured a low energy heating, cooling and solution that reduces demand on the electricity supply and provides a comfortable, well-controlled environment for their employees.

Hotel Europa

Rust, Freiburg



Germany’s Europa Park resort based in Rust, Freiburg, has recently undergone a major renovation within its ‘El Andaluz‘ and ‘Castillo Alcazar‘ hotels, where 300 rooms now benefit from Panasonic’s innovative VRF air conditioning systems.   

The Europa Park resort is one of the most prestigious leisure parks in the world, boasting five 4-star themed hotels and over one hundred attractions, drawing more than five million visitors through its doors each year. The family owned resort, voted best theme park worldwide for two consecutive years, prides itself in its commitment to consistent, high quality standards surrounding its attractions, food and beverage, shows, gardens and, its themed hotels.   

181 rooms of Europa Park’s ‘Spanish summer residence‘ themed hotel, "El Andaluz" required two phases of a complete renovation, and equipping the rooms with the latest air conditioning technology was high on the hotels brief. Similarly, 112 rooms of the ‘Castillo Alcazar‘ hotel, themed around a Spanish knight's castle also required a smart air conditioning system that would lower the overall bills of the hotel whilst ensuring guests comfort at all times.   

Freiburg based Installer, BS-Air GmbH, was tasked with providing a reliable and sustainable heating and air conditioning system. The technologies needed to be of high quality, quiet when in use and as inconspicuous as possible. This was a major challenge as no two rooms across either of the hotels were the same. The hotels high volume of occupants meant it was imperative for a quick and easy installation to minimise the disruption and down time of the building whilst the rooms under-went its HVAC revamp.    

The installation was implemented in two phases. Initial planning and design began in 2012, where detailed CAD drawings and air conditioning load calculations according to VDI2078 were first established. Between 2012 and 2013, 3,500 meter copper cables were laid within Hotel El Andaluz, whilst and 82 rooms were appointed with a new Panasonic air conditioning system within just eight weeks. The second phase commenced between 2013 and 2014 where 211 rooms between ‘Castillo Alcazar‘ hotel and "El Andaluz" hotel were commissioned within just nine weeks.   

"The biggest challenge in the two hotels at Europa-Park was probably the strict time limits we were restricted to, “explains Peter Scheidthauer, Managing Director of BS-Klima GmbH. “We are proud that we were able to implement all systems throughout both hotels in such a timely manner, all thanks to our dedicated employees. We would also like to thank the management of Europa-Park for putting this trust into us to create a fully integrated and reliable heating and cooling system for two of its 4-star hotels".   

Panasonic’s ECOi range of VRF systems were selected thanks to its impressive performance, new DC inverter compressor, new DC fan motors, a newly designed heat exchanger and its low power consumption which is achieved through the use of the high-performance refrigerant, R410A.   

A total of 14 outdoor units were installed between both hotels, ranging in output sizes from 22.40 kW to 45 kW*. ‘El Andaluz‘ homes nine of Panasonic’s ECOi VRF systems whilst the ‘Castillo Alcazar‘ boasts five units, producing a total refrigerating capacity of 500.80 kW.  

Once the outdoor systems had been fully installed, BS-Air moved into the indoor units of the hotels. In order to camouflage the systems against the low ceiling and interior design of each room, the installer decided Panasonic‘s MM1 series would be the ideal solution for indoor heating and cooling, thanks to its shallow channel devices. With a height of just 200mm, Panasonic’s MM1 Superflat channel devices offer the ultimate flexibility and are suitable for installation narrow, false ceilings. With its high energy efficiency and extremely low noise levels, this was the perfect solution for Europa Park’s indoor heating and cooling requirements.   

For accurate and flexible control of Panasonic VRF systems, an interface designed and programmed specially by wholesaler Alfred Kaut GmbH + Co. integrates the VRF system into the hotels in-house building management system. This enables quick and easy central control and the detection of faults. Three heating and cooling settings are controlled via the building management system, which is set depending on whether the room is occupied, how many people are straying in the room, and also allows for a basic temperature set point. Each individual hotel room was also equipped with Panasonics CZ-RE2C2 Hotel Remote Controller for guests to adjust the temperatures at the touch of a button. This remote makes increasing or decreasing the temperature, fan speed or shutting off the system completely a hassle-free process.   

"We could not close our hotels for more than a few weeks for renovation, therefore it was important that we put our trust into companies that we could rely on and that we could trust to not neglect the quality of equipment that was specified, and the implementation of these systems. BS-Air GmbH provided us with the best advice in recommending Panasonic air conditioning systems, and our high quality standard has remained firmly intact," says Roland Mack, owner of Europa Park.   

The project has been such a success that it was awarded a Panasonic PRO Award for Best Hotel Installation.

Oil Burner Alternative

Cambridge, UK

Aquarea air to water heat pump, Residential



As public awareness and new technology continues to progress, homeowners are constantly striving for a way to lower their bills and establish a ‘greener’ way of living. For one homeowner, Panasonic’s Aquarea heating and cooling system was the perfect match when looking for an alternative, environmental solution to the existing oil fired burner.

The homeowner’s four bedroom family home in Comberton, Cambridge was previously heated by an old oil fired burner. Although at the time of renovation oil prices were low, the homeowner also understood these prices could rise. The volatility in the price of oil, alongside the high maintenance cost of the tank as well as being reliant on the delivery of the oil led to the search for a new heating and hot water system.  

Local energy efficiency specialist and installer, Eco Installer, was tasked with proposing a sustainable alternative. Not only did the homeowner want to run an environmentally friendly property, but she also wanted to reduce her energy bills.   After considering the available options, it was agreed that a modern air source heat pump was the only reliable solution. With a guaranteed saving against oil heating, a heat pump also allowed the homeowner to cut her carbon emissions down significantly.  

Panasonic’s 12kW split system T-Cap air source heat pump was specified for the project. Replacing the current oil burner, the Panasonic system was teamed with both a Panasonic Aquarea indoor cylinder unit and DHW buffer tank to tend for the families heating and hot water needs. Panasonic’s DHW hot water tanks offer impressive efficiency, with a large surface exchange area and high insulation levels to minimise energy losses.  

“Once we had established our client’s desire for a super-efficient, environmentally friendly heating and hot water system with low running costs and minimum maintenance, Panasonic was our first choice,” explains Shane Freeland, Director at Eco Installer. “Panasonic’s impressive Aquarea T-Cap range stood out as the perfect solution. Its ability to maintain the same nominal capacity even at -15C without the help of an electrical booster heater, alongside its reputation for the best efficiency compared to other heating systems meant we could guarantee our client a reliable and sustainable source.”  

Panasonic Aquarea heat pumps have a maximum COP of 5.08 at + 7C, making them more efficient than fossil fuel, oil fired burners, gas boilers and electrical heaters.  Alongside being very quiet when in use, the systems also have a night mode program for even lower noise. This is controlled via its accompanying remote control which also features an auto mode, holiday mode and a special concrete speed drying mode to ease installation.  

For the ultimate sustainable solution Eco Installer connected the Aquarea heat pump to a solar kit and iBoost system to increase the overall system efficiency and minimize the impact on the environment as requested by the homeowner.  

Within one week, Eco Installer had replaced a dated and costly heating and hot water system with Panasonic’s efficient heat pump, buffer tank and indoor cylinder, replaced all radiators and installed solar technology.

Lees House, Brighton


VRF, Offices



Panasonic has supplied an efficient and easy-to-install heating and cooling system to a refurbished office building in the centre of Brighton. Hastings-based installer, Coolerway specified Panasonic’s innovative 3-way Multi Heat Recovery Control Boxes and VRF ECOi system to provide a solution that not only offers simultaneous heating and cooling, but is also easy for staff to control.   

The new tenants of the ground floor of Lees House, leading digital marketing agency Net Natives, carried out a significant refurbishment to their two office spaces, creating a trendy, industrial-chic style. The architect, Jeremy Diaper of Chalk Architecture, was keen to leave the original terracotta ceiling tiles exposed, which meant that the heating and cooling system wouldn’t be hidden above a false ceiling. This stripped-back style helped to cultivate the industrial aesthetic, so that the piping and units of the heating and cooling system became architectural features, rather than simply functional pieces of technology.     

With Panasonic launching its new 3-way multi HR control boxes towards the end of 2015, Coolerway saw the benefits of the new product, and quickly identified that this project would profit from having these systems installed. Supplied via Panasonic distributor, TF Solutions, Coolerway installed two HR control boxes, one in each part of the office, and linked the system to 8 Panasonic 4-way cassette units.   

For the installer, this new system cut down the project time significantly, as the new 3-way Multi HR Control Box removes the need for installing individual 3-way PCB and solenoid valve kits for each indoor unit. It also simplifies and reduces costs and timing in installation and designing processes. For the end user, the benefit is that each cassette can be controlled individually, allowing one to be in cooling mode while the other is in heating mode.   

“Using Panasonic’s Multi HR Box, we were able to drastically cut down the installation time on site, as we just put the box up and attached each unit, it was really that simple,” said Greg Smith of Coolerway. “It also makes piping design and installation much easier, because its features connection tubes for the main refrigerant circuit lines on both sides of the unit, which is another fantastic innovation. We are looking forward to using it on many more projects.”   

Coolerway installed 3 Panasonic VRF ECOi outdoor units to provide simultaneous heating and cooling to the refurbished ground floor office. Due to limited roof space, the installer required a space-saving solution. The Panasonic units are among the most compact on the market and take up very little installation space, so were the ideal choice for this project.     

To enable local control of each cassette, Coolerway linked a Panasonic CZ-RTC4 controller to each unit. This offered employees a wide range of options for controlling their environment, including changing the temperature, the fan speed and air flow direction, as well as programming a weekly function. The CZ-RTC4 is very straightforward to use, allowing employees with no experience of heating and cooling solutions to easily adjust the temperature to suit their needs, creating a comfortable environment for all staff members.   

Panasonic’s efficient and flexible heating and cooling solution has proved a huge success in the refurbished Brighton office, providing a comfortable working environment for staff, and contributing to the stripped-back, industrial aesthetic of the trendy office. Its market-leading technology, including the 3-way heat recovery control boxes, ensured that project was completed quickly and simply by Coolerway.

K Club, Co. Kildare


VRF, Hotels



Panasonic has installed a comprehensive heating and cooling system in the new 70-bedroom extension to the prestigious and internationally-renowned golf resort, the K Club in Ireland. Working with installer Crystal Air and O'Connor Sutton Cronin Consultant Engineers, Panasonic supplied an energy efficient VRF system that both blended into the interior design of the hotel and provided a quiet and subtle heating and cooling solution.

Host to the 2006 Ryder Cup and 13 European Opens, the K Club attracts golf aficionados from across the world, with 2 courses designed by golfing legend Arnold Palmer. Guests staying in the hotel and spa expect the very best, to which the heating and cooling solution could be no exception. The system needed to be quiet, so it wouldn’t disturb guests sleeping in the bedrooms, and discreet, so as not to negatively impact on the luxurious look and feel of the elegant, exclusive hotel. It also needed to be flexible and easy to control, to cater for the varying requirements of golf fans from across the world.  

“We are very proud of the work we did at the K Club,” commented Vincent Mahony, National Account Manager at Panasonic Ireland. “To be involved in such a prestigious project and provide a solution that exceeded the hotel’s expectations was fantastic. We focus on creating heating and cooling systems that are not only energy efficient and effective, but offer real comfort and control to the end user, and the project at the K Club is a great example of this.”  

Panasonic’s VRF ECOi system provided the perfect solution for the K Club’s exacting requirements. The extremely quiet MM Ducted Indoor Units, designed specifically for the hotel market, ensured minimal noise disturbance, and the ultra-slim space-saving design offered an unobtrusive way to deliver hot and cold air into the bedrooms without interfering with the aesthetic of the interior. Panasonic also provided an easy–to-use control panel in each room, so that guests had complete control over the operation of their air conditioning, allowing them to create the conditions that were comfortable for them.  

Panasonic’s unique off-coil temperature control facility of its VRF system was crucial to the success of the project. Not only does it allow each unit to be controlled individually to enable personalised cooling for each room, but it ensures that the temperature of the air leaving the unit can be raised, and can be set at any temperature between 7 and 22°C. With warmer air leaving the unit, it eliminates cold air dumping and drafts, and ensures that overnight rooms don’t become too cold.  

The K Club was keen to boost its sustainability credentials, and a key part of the project specification was that the cooling system must be very energy efficient. The Panasonic VRF 3-Pipe ECOi MF2 system, installed in the K Club, is optimised to provide maximum output with low consumption, with a market-leading COP rating of 4.76 and can offer simultaneous heating and cooling for up to 52 indoor units. The MF2 also takes up very little installation space, making it much easier for Crystal Air to complete the project.  

Installation at the K Club was a significant challenge due to tight time constraints, and the Club’s desire for the building works not to intrude on the luxurious ambience. Walsh Mechanical, the contractors who carried out the project, were given 5 months to complete the installation in 70 rooms that formed the new extension to the hotel, a very short timeframe which they nevertheless achieved.  

In order to avoid disturbing guests and maintain the peaceful atmosphere of the hotel, spa and golf course, Crystal Air and Walsh Mechanical were limited to certain areas at specific times and had to keep noise pollution to a minimum. To ensure that guests still enjoyed the 5-star experience while the construction was going on, contractors were kept out of eyeshot of the hotel guests. With all these restrictions on installation, it was essential that the heating and cooling system was simple and easy to install.   Panasonic’s VRF ECOi system provided the perfect solution to meet the K Club’s exacting requirements for the hotel’s heating and cooling needs: energy efficient, quiet and discreet, and offering comfortable conditions for guests. Crucially, the Panasonic system is easy to control, with a very user-friendly control panel, so that guests are able to select their preferred climate easily.

Panasonic Provides Air-Conditioning Solution for Historic CHQ Vaults  

When looking for the ideal air conditioning system for an eco-friendly office refit at the listed CHQ Vaults in Dublin, the developers selected a Panasonic VRF system.  The unusual architecture and historical importance of the vaults presented some interesting challenges for this installation, which were overcome thanks to the flexibility of Panasonic’s system.

The CHQ Vaults, situated in Dublin’s historical docklands, were originally used to store tobacco and whiskey in the 1800’s. Many years later, during the 2000’s, the building was refitted to accommodate retail units, when the space became a shopping haven. Now, in its most recent transformation, the vaults have regenerated into a buzzing commercial hub of offices, restaurants and bars.  

The client, Dogpatch Labs, wanted to create an innovative, tech co-working space utilising a 13,500 sq ft area within the vaults. The interior design needed to incorporate the original features within the space for an eclectic and unique working environment. Dogpatch worked with CEL Consultants to bring the vision to life. When it came to heating and cooling, they called in specialist air conditioning and ventilation experts Crystal Air Ltd to install a system that would both work with the structure of the building and effectively ventilate this old, underground space.  

“Panasonic provided the best solution for us to overcome the several unique challenges that the installation at Dogpatch Labs presented,” said Don Hoban, Business Development Manager, Crystal Air Ltd. “The flexibility of their VRF ECOi MF2 series and floor-standing units allowed us to overcome every roadblock within one system. The installation took six weeks and the finished result not only looks great but will also provide an economical and sustainable solution for the client.”  

The vaulted brickwork structure of the building combined with its listed status meant that Crystal Air already had several challenges to overcome. Firstly, the air conditioning system had to be easily removable in case future tenants wanted to fit an alternative solution. Secondly, none of the installation work could damage the bricks and mortar of the original vaults, and nothing could be attached to the historical vaulted ceiling. The system also needed to provide consistent cool, clean air throughout a large office space of over 150 desks, to counteract the underground atmosphere for a comfortable environment.  

The Panasonic 3-Pipe ECOi MF2 Series overcame each of these challenges, whilst providing an energy efficient and economical solution. The sophisticated design of the floor-standing units meant that they could be easily removed and did not need to be attached to the fabric of the building, leaving the vaulted ceiling free from any fittings. To save energy, the system, which can provide simultaneous heating and cooling, can also extract warm air and redistribute it to cooler areas of the working space.  

Ease of control is crucial to a heating and cooling system, particularly where staff may not have the expertise required to operate a complex control system. Crystal Air installed 12 Panasonic CZ-RTC2* controllers, to enable sophisticated yet simple local control of each floor-standing unit. The CZ-RTC2* allows employees to change the temperature, fan speed and air flow, as well as the operation mode. Local control is essential to creating a comfortable space for staff, as it means that everyone’s preferences can be catered for.  

The Panasonic system, installed by Crystal Air, more than met every expectation of CHQ Vaults. It not only provided an efficient and effective heating and cooling solution, but also preserved the beautiful interior of the historic building.  

*Panasonic has recently launched its latest controller, the CZ-RTC4, which has a brand new interface and a wide range of features, making it easier than ever to create the perfect atmosphere.

Salford, Manchester

VRF, Offices


When looking for a suitable air conditioning system for the sustainable and low carbon regeneration of Soapworks in Manchester, the developer selected a Panasonic VRF system.  The site, owned by global asset management company The Carlyle Group and joint venture partners Nikal and Abstract Securities Ltd, is of significant historical importance, so any installation had to be sensitively and sympathetically handled.   

Soapworks, originally home to Colgate-Palmolive in the 1800’s, is situated in Salford Quays, Manchester. This landmark development to turn the former factory into a modern office space spanning a massive 400,000 sq ft has been divided into three-phases due to its vast scale; phases one and two totalling around 230,000 sq ft, and up to 160,000 sq ft in phase three which is still to be developed. High profile organisations already confirmed to occupy the building include communication giants TalkTalk, MWH Global and The Home Office.  

When the developer put the heating and cooling contract out to tender almost three years ago, they had very clear objectives of what the system would need to achieve. Due to the structure and historic features within the building, including a vaulted ceiling, the developer didn’t want to install conventional building services hidden above a false ceiling; therefore they needed a system that could be seamlessly installed under the floor. The system needed to be energy efficient to meet modern office standards but also to support Soapworks’ sustainability goals, which include scoring a ‘B’ for its Environmental Performance Certificate. The Intelligent Comfort Group (ICG) won the contract after a competitive selection process, thanks in part to Panasonic’s unique and flexible offering.  

The Panasonic 3-Pipe ECOi MF2 Series provided the ideal solution for the Soapworks installation, thanks to its adaptable design, energy saving attributes and simultaneous heating and cooling capabilities. “Due to the scope and prestige of this project, all of the fittings needed to be reliable, sustainable and of the highest quality. ICG presented the ideal air-conditioning solution that met all of our objectives, and we are very pleased with the results. With a huge space of over 230, 000 sq ft to manage, the Panasonic system provides consistent and comfortable temperature control of the entire building.” Says Jennifer Bamber, Manager of Soapworks.  

Design flexibility coupled with sustainable heating and cooling

Soapworks required a system that could operate impeccably underfloor to suit the interior design of the building. With adequate underfloor space available, MF2 variable static pressure units, which would usually be fitted into the ceiling, were instead installed underfloor to meet the design criteria. Bespoke grills, which have been evenly distributed throughout the floor space, allow the warm air to be dispersed around the room.  

Another key requirement was energy efficiency. The Panasonic system was selected for this project because it could guarantee consistent leaving-air control of 16 degrees, 4 or more degrees higher than other manufacturers. This is the ideal temperature for warm air to rise and effectively distribute for a comfortable environment, without the need for additional energy being used.  

In addition, EVR units offer variable heating and cooling at the same time, which further saves energy as warm air can be extracted and distributed to other areas of the building. This ecological transfer of heat supports the project’s sustainability objectives and modern office standards for energy efficiency.  

Simon Kirk from ICG explains; “The 3-Pipe ECOi MF2 gave us the armour we needed to win this contract. Leaving air temperature was an important factor for the client to ensure they were being as energy efficient as possible. The 16 degrees offered by the Panasonic system is unique to the brand, and offers the best available option for a project such as this.”

Wealden District Council


Aquarea air to water heat pump, Residential


For many years, the search for a reliable, efficient and long-standing renewable energy solution has been at the top of the agenda for social housing providers, councils and communities alike. Renewable technologies not only provide a cleaner, safer and more efficient heating and hot water solution, but these technologies are above all cost effective.  

Whilst all renewable technologies can protect tenants from the growing risk of fuel poverty, certain systems are better suited to different properties. It is crucial for installers to specify the right system for each project, allowing the tenants to enjoy maximum benefits.   

A great example can be found at the Wealden District Council.  In fact, Ecosphere Renewables has just been awarded a top prize in Panasonic’s PRO Awards, winning the Best Residential Project in the Social Housing category for its ambitious project with Wealden District Council. This project has already seen 110 Panasonic Aquarea air source heat pumps and tanks successfully installed, delivering significant benefits to both the council and the tenants.    

The Brief
In August 2013, Wealden District Council launched a £291,000 pilot scheme, grant-funded by the Department of Energy and Climate Change (DECC). The aim was to update the heating systems of 110 village properties to fall in-line with the Government’s energy efficiency targets by 2015.    

Led by Abdul Hussain, the Wealden Home Energy Efficiency Officer, East Sussex based installer Ecosphere Renewables, signed a ten year contract to replace the solid fuel heating and electric storage heaters with a reliable, efficient and durable renewable technology solution within these properties.      

“Despite using other large manufacturer-branded air source heat pumps in the past, it was obvious that switching to Panasonic’s Aquarea Mono-Bloc units would be more beneficial to our customers and the environment,” explains Abdubl Hussain. “At the end of the day, cost, reliability and COP performance is essential for meeting council objectives and ensuring that our residents are in a well-heated, happy environment. Panasonic’s Aquarea heat pumps offer just that, and are fully compatible with solar PV panels.  Heat pump technology is also eligible for payments through the Government’s Renewable Heat Incentive (RHI).”  

Originally, 60 units from another manufacturer were trialed alongside two Panasonic Aquarea units. After extensive comparisons, the Panasonic units delivered better value and higher efficiencies. With an impressive co-efficiency performance rating of 5.08 and compatibility with solar PV panel technology, switching to the Aquarea air source heat pumps improves performance for the Council’s tenants – as well as the surrounding environment.
This project had major challenges as there was a significant variety in the types of properties requiring new systems. The houses were mainly rural buildings, built from the 1900’s to 1990’s, with differing construction materials, insulation and existing heating systems.  An additional challenge to be addressed was the variety in the tenants themselves, from families with small children to persons of an elderly age. With little knowledge of renewable technologies, a number of tenants were unsure about replacing their existing, traditional heating system with a new renewable technology.

Therefore, over a series of days, Panasonic took its fully working Aquarea air-to-water demonstration trailer to the Wealden district, allowing visitors to see the system first hand, hear how quiet it is, and appreciate its compact size. Representatives from Panasonic, Wealden District Council and Ecosphere were on hand to answer any questions and explain the benefits of having a heat pump installed. That same day, over 40 residents signed up to the Wealden District Council’s programme.   

The Panasonic Solution 
Now, 110 Panasonic Aquarea air source heat pumps and Panasonic tanks have been installed, with the project continuing for a further eight years. The systems specified include the Aquarea Mono-Bloc in 6, 9 and 12kW, along with ten Bi-Bloc units, which are installed across a block of ten flats.   

“This is one of the largest projects we have ever worked on - with strict budgets, hundreds of tenants relying on our install and tight deadlines to work to, we had no room for fault when specifying our choice of technology. We have installed Panasonic’s heat pumps for many years and have always found its systems to be one of the most reliable and efficient technologies on the market today,” says Sam Phyall, Renewable Energy Manager at Ecosphere.  “We are proud of the impact our installs have had on the community already. One family of five had their solid fuel back boiler with separate immersion heater replaced with an Aquarea unit; they are now saving £150 a month on their heating bills compared to before.”                   

Panasonic’s Aquarea air source heat pumps have a COP of 5.08, meaning for every one unit of heat the pump consumes, a further 5.08  units of heat is created.  This will reduce the Wealden District’s carbon footprint by an impressive 5000 tonnes over the next seven years and, on average, will save tenants £500 a year on heating bills. By replacing oil boilers and inefficient storage heaters, Wealden District Council has also seen a significant reduction in maintenance costs and breakdown call outs.                     

Panasonic’s heat pump technology qualifies for the governments RHI scheme, meaning the council will   benefit from an average payment of £500 per property per year over seven years.                    

As a result, Ecosphere Renewables has helped Wealden District Council reach its targets under the Home Energy Conservation act. The council are now considering heat pumps for all their off gas small   properties and flats within the Wealden District.

Renault-Nissan Dealership


Commercial, VRF, Others


Gennevilliers, 26 January 2015 – Panasonic Heating and Cooling has just fitted out the Renault-Nissan dealership in Romans-sur-Isère (southern France) with two ECO G VRFs.

Heating in the Renault-Nissan dealership in Romans-sur-Isère was originally provided by a gas-fired air heater. The dealer wanted to change the system so it would provide both heating and air conditioning. Using a 100 % electric VRF presented some problems. Considering the footprint of the building (1450 m²), such a solution would have consumed too much electricity, so much it would have required increasing the power supply to the site. This is why the dealer preferred the Panasonic Gas VRF solution, a system capable of providing heating and air conditioning without causing an increase in energy costs.  

An air ventilation system combining aesthetics, efficiency and innovation
The heating and air conditioning system had to meet strict criteria. It had to respect the design of the site and the Renault-Nissan visual identity while providing maximum comfort to customers and employees and limiting the site’s electrical consumption. Particular care was taken with the aesthetics. Panasonic preferred interior units that were as discreet as possible (ductable), and customized the housings to the colours of the dealership so as to integrate them harmoniously with the decor.  

Panasonic VRF, combining simplicity and effectiveness

Split into two buildings, the Romans-sur-Isère dealership’s footprint exceeds 1450 m² with offices, sales areas, delivery areas, and a computer room.   No fewer than 30 interior units were installed (high-pressure ductable units for the sales areas, housings and wall units from the offices, two mini splits for the computer room and is the after-sales area) and two ECO G VRF units placed on the roof of the building. The reversible system can provide either heat or cooling in optimal conditions of comfort: each room is independent with a temperature control by thermostat. “This dealership is the perfect demonstration of the advantage of a gas VRF solution, especially when the site to be air-conditioned is subject to severe energy constraints,” highlights Hervé Guillard, manager at Panasonic Heating and Cooling in France.  

Focus on the Panasonic Gas VRF

A professional solution, the Panasonic GHP VRF range is a market leader. This range has been specifically designed to save energy, especially for projects subject to restrictions in electrical power. These systems offer high effectiveness and performance with maximum relia bility. They enable considerable energy savings. Using Panasonic Gas VRF limits maintenance costs and is the perfect solution to heating, air-conditioning and cooling needs. The noise level is considerably reduced, which is particularly important to guarantee the acoustic comfort of users and the surrounding neighbourhood.

Mead's Business Centre


VRF, Offices


Panasonic’s market leading heat pumps have been installed in the Meads Business Centre in Farnborough, Hampshire, to provide heating and air conditioning to the centre owner, London-based property development company St Modwen.  

The Meads Business Centre is a fully furnished office building set in the heart of Farnborough’s Meads district, surrounded by major retailers and leisure destinations. Installers Woodhouse Environmental Services were tasked with designing and installing a heating and air conditioning system that would be energy efficient and fast to install, without interfering with the design aesthetic of the interiors. St Modwen, the centre’s owners, also needed the system to be flexible enough so that it could be used by a future tenant without requiring any further changes.  

“The key concern was to select a system that was energy efficient, quick and easy to install and flexible enough for us to adapt the design to the needs of the site,” said Trevor Woodhouse, MD of Woodhouse Environmental Services. “Panasonic’s system was ideal for this project so for us it was really a simple decision. The tenant’s own facilities team agreed when they came over for a final inspection from the USA, they thought it was fantastic.”  

The architect working on behalf of the tenants, sustainability consultancy Hurley Palmer Flatt, had decided to have all the services on show with a flat concrete ceiling above and large vaulted areas in between. This presented a particular challenge to the design of the heating and air conditioning system, as it meant that the positioning of all the components of the system had to be carefully planned, including the units, ductwork, cable tray pipe runs and drain services. The components also had to be meticulously laid out to ensure that the system looked completely uniform to retain the aesthetic of the interior, which again presented a challenge to the installers from Woodhouse.  

These challenges required Woodhouse to design a system that was quick and easy to install, but that also provided functionality and control to the end user. Working with distributor Environmental Site Supplies (ESS), they specified a Panasonic system, which allowed them to create a flexible design with a high energy efficiency rating. Panasonic air conditioning systems also lead the industry with their low levels of noise, which enhance their value for use in such office projects because they don’t disrupt a peaceful and productive atmosphere. Woodhouse installed two Panasonic 3-Pipe ECOi MF2 VRF systems, an extremely efficient outdoor unit that can heat and cool simultaneously and is easy to install and maintain.  To meet the architect’s specified design style, inside the office they fitted multiple concealed ducted units, the Panasonic S-36MF2E5, and a wall-mounted unit, the S-36MK1E5.  

To ensure accurate zonal heating and air conditioning Woodhouse installed the CZ-256ESMC2, a web enhanced touch screen controller that gives central control to a designated user. This function also ensures that unauthorised individuals cannot interfere with the system by changing the temperature settings. The company also installed a range of energy recovery ventilation units, which improve running costs by reducing the load on the air conditioning units by about 20% and also ensure cleaner air coming into the building.  

Panasonic’s system installed on this project was comprised of a range of their most advanced products. The indoor units specified by Woodhouse are easy to install and maintain and, crucially for an office environment, have industry leading low sound levels, meaning disturbance is kept to a minimum. The intelligent controller allows flexibility in how much control is given to individuals, limiting their influence on factors such as temperature and timings of operation. The heat recovery units recover up to 77% of the heat in the outgoing air and also have very low sound levels.

Heal's Building, London


VRF, Offices


The Heal’s Building on London’s Tottenham Court Road has long been a home of innovation and high quality design. This creative spirit lives on in the newly refurbished building, with a cutting edge heating and cooling system from Panasonic that provides a comfortable environment for the staff of companies such as Netflix and Deliveroo.  

Consultants Cundall worked with Easy Air Conditioning to design and install a heating and cooling system flexible enough to meet the demands of a variety of office spaces spread over five storeys. The scale of the project demanded a powerful, efficient system, so Easy Air Conditioning and Cundall specified the Panasonic ECOi VRF system. During three phases of delivery Easy Air Conditioning installed 24 VRF systems comprised of 42 of Panasonic’s heat recovery and heat pump condensing units. Each VRF system is controlled by a Panasonic CZ-256ESMC2 touchscreen controller and is integrated into the building management system of the site, to provide a flexible and user-friendly heating and cooling solution.  

“When we worked out the scale of the project and how many units we would have to install, Panasonic’s VRF system became the obvious choice,” said Andy Wootton of Easy Air Conditioning. “We wanted to give the client a heating and cooling system that was easy to use and provided the capacity they needed, and Panasonic ticked all the boxes. They offer great products which are easy to install and very energy efficient.”

Panasonic heat recovery and heat pump condensing units lead the market in their ease of installation and maintenance, which were key factors on this project as the units were to be installed on the roof of the building where space was limited. The ECOi VRF system also puts energy efficiency at the forefront, while able to offer heating and cooling simultaneously at high performance, making it the perfect solution for a large office building with hundreds of staff.  

The floor to ceiling heights in the Heal’s Building are lower than one might typically find in a modern office building, due to its heritage as a furniture manufacturing facility. Easy Air Conditioning therefore selected and installed Panasonic’s MM range of horizontal ‘slimline’ ceiling-mounted units, designed for spaces with low ceilings. These units are specifically designed for applications where there is limited height above a false ceiling. However, as the architect did not want to fit a false ceiling in the space, due to the lack of height, this meant that the cold air supply from the outlet diffusers could potentially flow straight down onto the people who worked below them, causing pockets of cold air around the office.  

Easy Air Conditioning also took advantage of the off coil temperature control facility of the Panasonic units, to maintain an ‘off coil’ temperature above 12 degrees. This meant that the air emitted from the units was already slightly warmer than a regular cooling system, minimising the risk of draughts. It was also decided to have metal plates installed under the units, around the outlet diffusers, to assist in creating a Coandă effect, where the cool air, on leaving the diffuser, flows out horizontally along the underside of the plates, and reduces the risk of the air falling straight down onto the people below. It also helped in providing a consistent cooling effect across the office. 

Easy Air Conditioning supplemented the ceiling-mounted units with a large number of Panasonic’s MR1 series floor standing units, concealed discreetly in cabinets beneath windows. These units, specifically designed to be concealed in perimeter enclosures, enable flexible installation as supply pipes can be connected to either side of the unit from the bottom or the rear. This flexibility ensured that areas of offices nearer the windows, which can be warmer in the summer due to the sun, were cooled to a temperature consistent with the rest of the office. Without a false ceiling, the units, trunking and pipes of the air conditioning system were exposed, so the interior designers decided to embrace this and incorporate it into the stripped back, industrial-chic design aesthetic of the iconic Heal’s Building.

Munich Municipal Hospital


Commercial, Public buildings


Server rooms containing elaborate technology become very hot, very quickly due to the heat emitted by the equipment. To ensure everything runs safely and reliably, temperature limits must be guaranteed. High internal demands however, do arise, not only because of technical equipment such as server racks, UPS (Uninterruptable power supply) systems or medical devices, but also because of the increasing density of upgraded or newly constructed buildings. All these factors mean the installation of air-conditioning units is indispensable.

An example can be seen at the Munich Municipal Hospital, one of Bavaria’s largest hospital associations.  The organisation has relied on air conditioning units to keep its UPS and server rooms cool for some time now. This prestigious medical establishment focuses on surgical procedures, among other specialities, and is one of the world’s leading hospitals in the field of hand surgery.

When the use of R22 coolant was banned completely at the start of 2015, the hospital had to renew its air conditioning system. The R22 ban means maintenance of the old equipment is no longer permitted where the coolant is concerned and the installation of a new air conditioning system was necessary on short notice, during operation, to prevent damage to the servers.  Also, improved energy efficiency was another benefit, as the new system offers the advantage of requiring at least 30% less electrical power to generate the same level of cooling capacity. The more units are replaced, the better the savings in running costs are.

This vision was pursued as early as autumn 2013. To that end, the hospital association’s planning department brought Elektro-Kälte-Wärme Forster, an electric heating and cooling firm from Schongau, into the preliminary planning stage for renewing the system. The contract was awarded and work began in March 2014. The most important points in the preliminary planning were the removal of the outdated R22 systems, the installation of the new systems and adapting them to the power requirements they had. In addition, the new air conditioning systems had to be integrated into the existing building management system (BMS).

By specifying Panasonic’s conversion solution, the existing R22 piping and electricity supply can still be utilised to install a new system which uses the R410A high-performance coolant. There are almost no manufacturer-specific restrictions apart from a clearly structured test procedure.

No interruptions to server
Furthermore, a redundancy switchover is provided to ensure the server runs without interruptions while adhering to the temperature limits. This was achieved by implementing Panasonic’s PAW-SERVER-PKEA interface, which ensures a redundant operation of two air conditioning systems. In this way, the interconnected systems can be controlled in redundancy or alternative operation, depending on the desired setting. As soon as one system switches to ‘failure’, the second immediately kicks in. The same is true if the ambient temperature exceeds the set point. Additionally, isolated contacts for switching on / off and an external failure report offer the possibility of external integration.

Already armed with the end-customer’s project specifications, Elektro-Kälte-Wärme Forster, who worked closely with Kaut in Munich, who offered constant help and advice from the initial concept right through to activation. As various modernisation measures were taking place in the hospital at the time, the project was divided into three phases and completed in 2014. It was, of course, necessary to respect the rest times in the hospital, as well as the fire protection conditions on-site.

Managing Director Lorenz Forster explains: “We chose Panasonic because we have successfully installed machines from the PKEA series in server rooms many times before. This particular product range, which is optimised for use in utility rooms was perfect for our end client.  It has special connectivity and runs very smoothly and very efficiently. These were decisive factors in the selection of this concept.”

Burger & Lobster, London


VRF, Restaurants



Burger and Lobster, the popular chain of restaurants, recently opened its latest eatery in a Grade II listed building on London’s Threadneedle Street. To provide the best possible guest experience, installers FWP and distributors Oceanair specified Panasonic’s ECOi VRF system to provide a subtle and unobtrusive heating and cooling system.

Oceanair and FWP faced a number of challenges when designing the heating and cooling system for this particular Burger and Lobster location. The restaurant is in a Grade II listed building, which meant that they were unable to make any major alterations to the property. The restaurant also features a beautiful period ceiling that Burger and Lobster were keen to leave free of obstructions, so FWP had to design a solution that made use of other architectural features and could be installed in a listed building.  

Burger and Lobster is open six days a week, from breakfast at 7am until late in the evening, and that restricted the amount of time FWP could spend on site installing the system. They therefore required a solution that would be quick and easy to install, occupy minimal space but still able to provide a powerful heating and cooling solution.  Working with Oceanair to define the final solution, FWP specified and installed the Panasonic ECOi 2-way VRF system, which is renowned both for its ease of installation and its capacity.  

In order to adhere to the restrictions imposed by the Grade II listing and Burger and Lobster’s strict interior design aesthetic, including keeping the ceiling free of air conditioning units, FWP had to devise a creative solution to ensure that the restaurant was perfectly climate controlled. They specified Panasonic’s concealed ducted units to be installed behind the banquette seating to provide a totally hidden, yet effective, air conditioning solution. Panasonic’s ducted units are also renowned for their near-silent operation, in keeping with the high-end but relaxing ambience of the restaurant.  

The busy location and long opening hours of the Burger and Lobster restaurant on Threadneedle Street were major factors in their specification of the Panasonic ECOi 2-way system, because it is quick and easy to install, so it minimised disruption to the restaurant. Just as FWP were restricted with what they could install in the public areas, there was also very limited space in the back-of-house area of the restaurant to position the VRF units. Panasonic’s ECOi 2-way units take up very little installation space, so were comparatively easy to install and meant that the design for the whole system was simple to achieve.  

London is famous for its unpredictable weather, so a restaurant needs to be able to adjust the temperature easily and quickly. FWP installed hard-wired controllers with the Panasonic ECOi system to give staff at Burger and Lobster total control over temperature, and the controller itself is easy to use, even for those with no experience of heating and cooling systems.  

Panasonic’s ECOi VRF system installed in the new Burger and Lobster restaurant on Threadneedle Street, London, suited the high-end ambience perfectly. The concealed ducted units provide a subtle, effective heating and cooling solution and the easy-to-install, compact VRF units ensured that the project was completed quickly and simply.

Pannal Water Tower


Aquarea air to water heat pump, Residential

Aquarea T-CAP


An abandoned water tower on the outskirts of Harrogate, Yorkshire, has been converted into a stunning family home by Carol and Majid Nadry from Bradford. Sustainability and energy efficiency were at the heart of the project, so they chose an air source heat pump from Panasonic to provide a low-Carbon heating and hot water solution.

The four-storey water tower, which was built in the 1940s to supply a nearby village, was in need of significant refurbishment, as it had lain derelict for several years. However, this offered the Nadrys a blank canvas on which they could design their home - and exactly the way they wanted it. Energy efficiency was one of the core principles of their restoration project, and this presented a number of challenges to Cumbria-based renewable heating firm Heacol, who were asked to design and install the heating and hot water system.  

System design has a significant impact on how efficiently it runs, as a heating system that is not designed and installed correctly will not deliver optimum performance. As a large four storey building, it was crucial that the property had a powerful water flow to provide an even capacity around the building, and that all this was achieved with energy efficient technology. As the water tower was so old and run down, the installation had more in common with a new build project than a retrofit. Heacol were therefore able to design the whole system themselves, rather than adapt it to existing infrastructure, which appealed to the Nadrys as it meant that they could ensure it was as efficient as possible.  

Heacol specified a Panasonic Aquarea T-CAP heat pump, which was integral to delivering the efficient solution and capacity they needed to heat a large home like the converted water tower. The T-CAP was the ideal solution as it is not just efficient and powerful, but also extremely reliable and provides advanced control options to make the system more efficient. The T-CAP also works well with underfloor heating, which was chosen as the primary method of delivering heating to the building, to increase the efficiency of the system.  

“We never have any problems with the Panasonic T-CAP” says Brendon Uys of Heacol. “It is one of the most reliable heating systems I’ve ever come across, in three years of installing it I haven’t had to do one repair job, I would go so far as to say it’s bulletproof. Another really important feature for me is how simple it is to install, it makes completing a project so much easier. It provides a really efficient solution as well, which is great for a family like the Nadrys who were keen to reduce their energy bills and be environmentally friendly.”  

Heacol installed two Panasonic Aquarea T-CAP heat pumps to provide the necessary capacity for the house. The T-CAP includes weather compensation controls as standard, so that when the outside temperature falls, the water temperature rises, meaning the system is always running at peak efficiency. Heacol also installed proportional thermostats so that when the outside temperature drops below 17°C the system will run 24 hours a day. This enables the system to run at a much lower flow temperature when providing heating and hot water, and therefore it consumes significantly less energy while still performing at peak efficiency. Heacol also installed a thermal store, which heats the water as it flows through a pipe rather than in a tank, which not only reduces the risk of legionella but also lowers the running costs of the system.  

Completely restored, the Pannal Water Tower is equipped with an efficient, fully-controllable heating and hot water system. With monitoring equipment recently installed, Carol and Majid Nadry will soon be able to see the significant savings on their energy bills generated the Panasonic Aquarea T-CAP.

Bochum University


VRF, Offices


A breath of fresh air for an old building - That was the brief for the conversion of a downtown office and commercial building in the centre of German city of Bochum into a university building complete with lecture halls and conference centre, the "blue square”.

The most important parameters for the project were:
·         Enough fresh air for 100 people on each floor
·         Use of the existing district heating system due to current contractual obligations
·         Air conditioning for secondary rooms
·         Limited space due to the inner-city location
·         Compliance with the Energy Saving Ordinance currently in force
·         Air temperature control, i.e. cooling and heating
·         Building data: Use of the first to fifth floors, each measuring 240 m², including lecture halls each measuring 130 m².

The requirements in the guidelines for places of public assembly meant each floor of the building would require approx. 3,000 m³/hr of fresh air. Early on in the planning phase, the decision was taken to use a central ventilation unit with a total of 15,000 m³/hr of fresh air and an integrated heat recovery element. The heat recovery rate is 75 % (depending on the operating condition). The air is distributed to each floor via an outdoor duct.

The integrated underfloor heating system covers the base load for heating, meaning the district heating is suitable for use here.

The only issue left to resolve was that of the air conditioning. This had to be done as much as possible on an individual floor basis depending on the layout of each lecture hall, as it was not always the same on every floor.

A VRF system (variable refrigerant flow) from Panasonic's ECOi series, which allows for individual temperature control for each cooling point, was therefore the obvious solution. Due to the wide-branching duct system however, it was not possible to use standard Panasonic components, as these do not have enough static pressure.

The ingenious approach of Bochum-based Climatic was to combine standard ventilation equipment from GEA with DX kits from Panasonic's VRF range. Each duct unit can heat or cool the air as appropriate, so temperatures do not fall below 14 °C in cooling mode or exceed 28 °C when heating. In addition, the air speeds had to be no greater than 1.5 m/s, to ensure comfort.

The cooling requirement for each lecture hall was estimated at 16kW and for the secondary rooms at 18 kW. The total cooling power required was calculated at 90 kW.

In order to minimise both the quantity of coolant in the entire system and the length of piping, two separate coolant circuits were selected, each with 14 hp / 45kW of cooling power.

The positioning of the two external components was also a problem, due to both the inner-city location and the building's listed status. The central air conditioning unit's position already took up the available roof space, both physically and with regards to the forces exerted on the building.

The solution was to set aside a room on the fourth floor as a plant room, which offered space for the control cabinet and the two external components. The air for both external components is drawn in via grills that were installed in the listed facade in place of windows. The air is then blown out again via two exhaust spouts over the roof of the plant room.
This solution also leads to reduced noise emissions.

For control, the team selected the central operating station from Panasonic's ECOi VRF range. This fulfilled the following requirements:
·         Free timer programming depending on the layout of the individual lecture halls
·         The ability to calculate energy costs individually in the event the building is rented to separate tenants
·         Web-based remote monitoring for service and elimination of faults, which ideally can be reset as they accumulate; otherwise, they can be analysed beforehand, allowing for better service planning.

The building started hosting lectures, ranging from business and law studies to cultural events, a year ago. Thanks to the outstanding energy efficiency ratio of 3.36 and the coefficient of performance of 3.85, the VRF system ensures energy efficient operation for both cooling and heating.

Family Home Warwickshire


Aquarea air to water heat pump, Residential


Many homeowners are looking at ways to utilise renewable energy to power and heat their homes, be it a heat pump or solar panels.  Panasonic has recently been involved in a unique residential property where both solutions have been installed and are working together to provide maximum energy savings.  

Originally a four-bedroom residential property situated in a village in Warwickshire, the homeowners invested the help of Nexus Building Solutions for a complete refurbishment and extra two-bedroom extension. The family were looking for a heating solution that would not only fit in well with the existing oil burner and radiators, but also provide reliable and superb-quality performance.  

Specifying 4kW Panasonic 250W HIC panels to accompany Panasonic’s T-CAP Monobloc Aquarea heat pump, PRO Partner Premium Installers of the month, Nexus Building Solutions has helped the property to benefit from extremely energy-efficient and cost-effective underfloor heating, which runs through six different zones within the house. Supplying heat to an extension for an elderly relative, the bedroom, living room and downstairs bathroom, as well as a two-storey bedroom and living room for the rest of the family, now all benefit from Panasonic’s renewable technology.  

There were two key motivators which lead them to decide on a new Panasonic Aquarea air source heat pump. Firstly the cost benefits; having a new large six-bedroom room property meant that their heating costs were significant and they were keen to find a solution that kept them warm while reducing their energy bills. Secondly the heat pump’s compatibility with solar thermal technology meant that the family could qualify for Government rewards from the FiT scheme and any surplus would go straight back into the pump. The family are now saving money every month compared to their previous fuel bills.    

“Since fuel prices continue to rise, we have seen a change in our customer’s heating needs, requirements and priorities,” says Avnash Jhita, Operations Manager at Nexus Building Solutions. “Faced with an economic climate that stretches outgoings, homeowners want energy-efficient heating and hot water on demand. Offering a heating solution that is affordable, reliable and offers an attractive return on investment, is vital for stimulating business.”  

Panasonic’s Aquarea heat pump does just this. With an impressive COP of 4.75 and option to add on a Panasonic PV panel, consumers are provided with a completely renewable and cost-effective energy solution, which sits in perfectly with current government incentives.   “We are delighted with the results from installing Panasonic’s Aquarea heat pump and PV solar panels,” says the homeowner. “Not only is the house warm and cosy, but the extra energy generated from the solar panels is transferred straight back into the pump. We’re so impressed that we’re currently in discussions with Nexus Building Solutions to install another Aquarea heat pump that will replace our oil system in the main house when a retrofit is required.”  

“Panasonic’s Aquarea heat pumps are very straight forward to use and easily controlled, just like a normal boiler - you flip down the lid, you select what sort of temperatures you want in the house for your hot water and what times you want it. It’s easy.”  

An extremely compact and versatile heating system – the Aquarea heat pump will be able to fulfil heating demands even in temperatures as low as -20°C. Independent tests have also shown that Panasonic’s air-to-water heat pump is capable of saving up to 78% on heating expenses, and far more efficient than fuel-fired boilers, gas boilers and electric heaters.  

Panasonic’s Aquarea is the most comprehensive, versatile and cost-effective range of air-to-water heat pumps on the market. It features heat pumps from 7 to 16 kW, single and three-phase alongside stand-alone and split-units.

Straffan Manor, Ireland


Aquarea air to water heat pump, Residential


Straffan Manor has recently been announced as an award winning development in the Panasonic PRO Awards 2014. A Panasonic Aquarea heating and hot water system was installed in all 21 of the 5-6 bedroom luxury homes in Straffan Co.Kildare, Ireland.  

The Straffan Manor development was constructed by Mulberry Properties Ltd – a second generation family business, renowned for building prestigious homes in Ireland. Panasonic PRO Partner Mick O’Shea Heating and Plumbing Ltd and Panasonic distributor Heat Merchants completed the team to bring this solution to life.  

The Brief

The client, Mulberry Properties Ltd was dedicated to not only comply with building regulations but aspired to surpass them to set a new standard. “The building industry has evolved dramatically over the past 2 years, with major emphasis on several aspects of design and construction. This includes a whole new approach to insulation quality, air-tightness and highly efficient renewable heat and energy sources” explains Fergal Flattery of Mulberry Properties Ltd. The key objectives in the construction of these new homes were to ensure that they achieved an A2 building energy rating utilising renewable energy sources and exceed the requirements to reduce the carbon emissions outlined in Part L. In addition to building homes with the best possible infrastructure, the comfort of the future occupants was also of paramount importance. Mulberry Properties Ltd wanted to install a user friendly heating system that would be easy to operate and maintain now and in the future, as well as complement the overall aesthetics of the development. Other key features taken into consideration were energy efficiency, low running costs and minimal disruption or excessive ground works during the construction phase.


Requirements for high efficiency in low ambient conditions and aesthetically pleasing units located away from the dwelling with a small footprint and no pipe work heat-losses were a challenge to the team. Mick O’Shea explained, “The utilisation of solar thermal technology combined with gas fired appliances in this project were briefly considered, but not selected in the final design of the heating system as it was determined that the changes to the fabric of the building and the required roof space for an adequately sized solar thermal installation were prohibitive”. In addition, the risk of Legionella in tanks for stored hot water was a concern, with the additional costs and adverse effects on energy efficiency of heating this water.  

The Panasonic Solution

After extensive consideration between Shane Duffy of Heat Merchants, Mick O’ Shea and Mulberry Properties Ltd, it was decided that a system featuring a heat pump was the best option with the Panasonic Aquarea T-Cap heat pump being the preferred option for the Straffan Manor homes. This option offered the capability to integrate the heat pump with other additional renewable energy solutions, thus delivering high performance whilst remaining energy efficient and affording the added bonus of low running costs. The excellent build quality of the Aquarea units coupled with the availability of a local Panasonic service engineer sealed the deal.  

The new homes now benefit from the Panasonic Aquarea T-CAP 12kW split system, which generates 100% of the domestic hot water and heating needed for the homes all year round, without the need for back up from a supplementary system. With energy saving being a priority, the energy consumption of the heat pump was offset through pairing it with a thermal store and photovoltaic panels.  

The requirement of heating stored hot water to eliminate the risk of Legionella and the associated increase in costs and decrease in energy efficiency was addressed by installing a Kingspan 540 Litre thermal store with domestic hot water coil.   Unlike conventional systems, there is no need to prioritise between heating and hot water. Due to the large volume of the thermal store there is never a dramatic drop in the temperature, allowing the Aquarea heat pump to comfortably recover the temperature. This solution maintains the efficiency of the heat pump keeping both energy consumption and costs to a minimum.   

In-roof solar photovoltaic panels were installed on the houses in Straffan Manor to complement the Panasonic heat pump. This will yield approx 1530 kWh of energy per annum and avoid CO2 emissions of 1,356 kg per annum. (See attached support document). Photovoltaic technology was selected over solar thermal systems as the heat pump has already satisfied the thermal requirements and was deemed to already deliver both value and return on investment. The solar PV system delivers total carbon neutral energy with minimal maintenance required. It was also easily integrated with the architects design and allows for future expansion.   

“As the heat pump relies on electricity, the client felt that having the capability of generating electricity would add to the value that the heat pump delivers. The client also decided to use underfloor heating on the ground floor which is ideally suited for use with a heat pump and thermal store. The houses in this development are air tight and as a result when the ground floor slab is heated this will, in turn, heat the whole building. Underfloor heating achieves optimal results and efficiencies from the heat pump,” concluded Martin Flattery of Mulberry Properties.  


Panasonic’s heat pump technology was a key component in the team being able to offer a first class heating system for the Straffan Manor residents. The Aquarea T-Cap split system exceeded all expectations and gained the properties A2 energy ratings, just 1 step below Passive house status. These new award winning houses will provide families with comfortable homes that are efficient and economical to run and easy to maintain for many years to come. Martin Flattery of Mulberry Properties Ltd concludes, “We are thrilled that Straffan Manor has received this prestigious Panasonic PRO Award and it is a credit to everybody involved”

Savills Head Office


Commercial, VRF, Offices


Ireland’s leading real estate organisation, Savills, recently acquired additional office space in Dublin’s city centre, at a location where power supply was extremely challenging with a grid operating at capacity.  Coupled with this, the property itself is a famous listed building, housing the company’s 170 Dublin-based staff and provides state of the art hospitality and leisure facilities for the Savills employees.  

Ethos Engineering was employed as the M&E consultant with L Lynch and Co working as the mechanical contractor, and Tech Refrigeration installing the solution. This team was tasked with providing a heating and cooling solution fit for such an iconic building that would cope with the demands that would inevitably be placed upon it, keep running costs low and provide a good payback period.  


The main challenge with this project was the lack of available power as the City Centre grid location was overloaded. When appraising the options available for Air Conditioning, Tech Refrigeration suggested Panasonic’s revolutionary gas-powered GHP technology. Jim Weldon, Director at Tech Refrigeration explains, “There would be a huge cost involved in upgrading the electricity grid with other solutions so Panasonic’s GHP VRF range was the ideal solution for this type of commercial application, especially due to the power restriction.  The consultants were also looking for a system capable of providing controllable comfort to the client's employees, offering flexible and efficient temperature and air flow management.”  

The Panasonic Solution

A complete installation of a Panasonic GHP VRF system capable of coping with a 243 kW Load was carried out, utilising the ECO G 3-way units. These outdoor units require only a single phase supply and as such allow the building’s electrical power to be used for other critical electricity demands which is vital in a large office space. The excess heat from the engine means that the gas heat pump air conditioner has no need for a defrost cycle, meaning lower running costs and a reduction in Carbon emissions. Heating outputs are also maintained even at ambient conditions as low as -20°C.     

Ethos Engineering commented, “The deciding factor for choosing a Panasonic Solution was the ability of the GHP system to use off-coil temperature-control. This enabled us to ensure the air condition would never reach a temperature that would be too cold for the occupants and instead, would be controlled to remain at a neutral, comfortable temperature. Each indoor unit has a built-in air temperature sensor which adjusts temperature automatically, something which other systems on the market just could not provide.”  

Ethos Engineering, L Lynch and Co and Tech Refrigeration worked closely with excellent support from Panasonic in Ireland to commission this system in such a prestigious location. The capability of the ECO G 3 way system to optimally cool and heat simultaneously with individual operation of each indoor unit from only one outdoor unit offers a flexible system to meet the demands of a busy office environment. The reduction of power loadings, especially during peak periods saves money and means the system’s payback period is noticeably shorter.

The project has been such a success that it has recently been awarded a Panasonic PRO Award for Best Contribution of efficient projects within Europe.

Smurfit Kappa

Dublin, Ireland

Commercial, VRF, Offices


Europe’s leading corrugated packaging company, Smurfit Kappa Group, has recently refurbished its headquarters in Dublin.  Alongside a new, modern and stylish interior, the building also benefits from heating and cooling solutions by Panasonic.  

Smurfit Kappa Group decided to undertake a major refurbishment of the property and wanted to fully upgrade the interior as well as the building services for this unique 1970s built office block.

Local installer, Tech Refrigeration & Air Conditioning, alongside consultant Ethos Engineering, have created a comprehensive, energy efficient and cost effective heating and cooling solution that features 81 indoor concealed ducted units, four GHP (gas heat pump) outdoor units, and 6 PACi systems from Panasonic.  

One of the key air conditioning design issues that the project team had to face was the lack of mains power available on site. This presented some challenges, but an innovative solution was agreed: the project would use Panasonic’s innovative GHP system. Being mainly powered by gas, a GHP system will deliver low running costs, reduce CO2 emissions and equally important for this particular project, eliminate the need for an expensive electricity supply upgrade that an alternative solution would require.  

Panasonic’s GHP range is extensive and leads the way in efficiency and versatility, being especially suitable for those commercial projects where power restrictions apply.

Jim Weldon of Tech Refrigeration & Air Conditioning was delighted with how the project team worked together to deliver a first class, innovative solution for a blue chip client:  “This was a prestigious project to be involved in, as Smurfit Kappa is an internationally renowned brand. As such, the challenge for the whole team was to make sure a suitably high spec system was created,” he comments. “I think we achieved that with everyone playing their part, all topped off by the advanced Panasonic GHP technology which ensured all our project goals and challenges were met.”  

While there was the mains power issue, the urban location of the Smurfit Kappa building also meant that any noise produced by the system condensers would need to be kept to a minimum.  Tech Refrigeration & Air Conditioning was able to reassure the client that Panasonic GHP runs as quietly as any equivalent system that is powered by electricity. Furthermore, running cost comparisons were drawn up by Panasonic Ireland and the favourable results were a critical factor in the specification process.  

Smurfit Kappa, alongside many forward-thinking businesses, wanted to ensure that carbon emissions would be tackled in a positive way. The project team was able to highlight how much energy would be saved using GHP, with a resulting 30% less carbon emissions into the atmosphere.  

The system is also extremely user-friendly and on-site staff take advantage of the Panasonic centralised controller to closely monitor use and management of the system around the building. Functionality includes a diagnostic health check of all systems and associated controllers.  In fact, the intuitive, user friendly nature of the controller, has been remarked upon by the client.  

The project has been such a success that it has recently been awarded a Panasonic PRO Award for Best Contribution of Efficient Projects within Europe.

The Brief
Nestled between The International Financial Services Centre, The Convention Centre Dublin and The 3Arena, Dublin’s 40-acre EastPoint Business Park provides state-of-the-art cost effective, flexible and well serviced office buildings to a thriving business community of 50+ companies and 6,000+ employees. The Business Park is set in beautiful landscaped surroundings alongside the Tolka Estuary and Dublin Bay.  

Easily accessible, EastPoint is home to Irish and International ‘Blue Chip’ companies, including one major, internet search giant. This particular company occupies 50,000ft² of office space in this prime location, which required a sustainable and energy friendly heating and cooling solution.  Dublin-based Panasonic PRO Partner, Tech Refrigeration was the installer for the Panasonic-specified VRF solution.    


The first challenge was the size and design of the building. System Installer Jim Weldon from Tech Refrigeration says, “This search engine giant needed to find a system that would more than comfortably cope with the 50,000ft² office footprint. The open atrium in the centre of the building was an aesthetic feature, however, cooling such a large space covered in glass in the height of summer and then heating it during the winter was a major potential issue.” This company employs over 280 staff from over 24 nationalities and keeping everyone comfortable was a real challenge.  However this was overcome thanks to the performance and flexibility of Panasonic’s heating and cooling technology.  

The Panasonic Solution

Panasonic’s 3-Pipe ECOi MF2 6N Series VRF solution was specified as a result of an excellent recommendation from the consultant Ethos Engineering, as it offers the best solution for this most demanding of applications.  

In a bid to ensure the comfort of the staff, the Panasonic system has a wide temperature setting range from 16-30⁰C. The large floor plan of the office space proved no problem for the ECOi MF2 range, as it is adaptable to various building types and sizes due to the options to select the best fitted airflow / static curve. In total, the installation covered four floors.  

“A major advantage of the Panasonic system over the competition was the ability for off-coil temperature control” continues Jim. “A sensor within the indoor units allows the overall system to adjust the supply-air temperature to a pre-set minimum temperature. This temperature is adjustable during commissioning to between 7 and 22⁰C.  This not only increases comfort, but saves energy and running-costs.”  

With any large scale system, maintenance will always be a factor. The benefit of using this Panasonic range is that even when an indoor unit requires maintenance, other units continue to function to decrease down-time and provide optimum system performance. Aside from the technical ability of the Panasonic hardware, the support of a local Panasonic installer with extensive experience, and the knowledge of the consultant, added to the confidence in this system.  


A key feature of this system was the ability of the Panasonic ECOi MF2 system to offer various comfort levels over different areas – and on such a large scale. The benefit of using this 3-pipe Panasonic VRF solution over a water-chilled system is the ability to offer efficient, demand based control, localised to each unit to provide either heating or cooling, offering maximum comfort and efficiency. With one outdoor unit chassis size offering economical dimensions, this solution offers maximum benefits and output with market leading COP as well as noise reduction.  

The project has been such a success that it has recently been awarded a Panasonic PRO Award for Best Contribution of efficient projects within Europe.

Family Home, Essex


Aquarea air to water heat pump, Residential


Rising energy prices coupled with the desire to be more environmentally friendly, lead an Essex family to make the switch to a more sustainable heating solution - Panasonic’s Aquarea air source heat pump.  

The Peters family were keen to make the change from their large and out-dated oil boiler in their Victorian home, The Old Rectory, to a more compact, energy efficient and economical system.  

There were two key motivators which lead them to choose the new Panasonic Aquarea air source heat pump. Firstly the cost benefits - having a large twenty room property meant that their heating costs were significant and they were keen to find a solution that kept them warm, whilst reducing their energy bills. The family are now saving approximately £200 per month compared to their past oil fuel bills - a considerable saving.  

The other significant reason for the install was the family’s wish to reduce their carbon foot-print and choose a system that was environmentally friendly. This follows a growing trend and greater demand for more sustainable energy and heating solutions.  

This particular installation was first approached by conducting an energy efficiency study – vital for a period property with over twenty rooms. Due to the house size the installers decided to fit two Aquarea units, in order to deliver the heat the house needs. Fortunately no changes were needed to the house itself, even the existing radiators were able to be retained. The house also had adequate existing roof insulation.    

“We are delighted with the results from installing the Panasonic Aquarea Heat Pump and the house always seems warm and cosy, despite such a cold winter” said the homeowner. “We are finding that heat pumps are a reliable system for our home, they don’t need any more maintenance than a gas or oil boiler and they deliver the hot water and heating that we need in our house, whilst saving money compared to our previous heating system.”  

“…We also like the fact that the Aquarea heat pumps are very straight forward to use and easily controlled, just like a normal boiler - you flip down the lid, you select what sort of temperatures you want in the house for your hot water and what times you want it. It’s easy.”  

Jonathan Evans of IME Systems Ltd, the installation company for this project commented: “We get asked sometimes what the benefits of the Aquarea heat pump systems are, so we tell our customers that Panasonic consistently produces reliable and good quality pieces of kit, and from our point of view as installers, they’re straight forward to install. Like any good quality air source heat pump they’re quiet and not intrusive, they don’t keep you awake at night with spinning motors and they don’t irritate your neighbours.”  

An extremely compact and versatile heating system – the Aquarea heat pump will be able to fulfil heating demands even in temperatures as low as -20°C. Independent tests have also shown that Panasonic’s air-to-water heat pump is capable of saving up to 78% on heating expenses, being far more efficient than fuel-fired boilers, gas boilers and electric heaters.  

Panasonic’s Aquarea is the most comprehensive, versatile and cost-effective range of air-to-water heat pumps on the market. It features heat pumps from 7 to 16 kW, single and three-phase, alongside stand-alone and split-units.

Family Home, Jersey

St Saviour, Jersey

Aquarea air to water heat pump, Residential


Panasonic’s market-leading Aquarea heat pumps have been installed in a large property in St. Saviour, Jersey, to provide heating and hot water to the family house and home-based business.  Switching from an old and expensive heating system, the owners are now benefitting from substantial cost savings.  

In 2014, Jersey-based installer, Plumbing & Heating Services (PHS) Limited, was tasked with removing an existing heating system, and specifying and installing a new energy efficient solution for a large property in St. Saviour, Jersey.  With five bedrooms, three reception rooms, three bathrooms and adjoining chalet space, the property, which is used as both a family home and the premises for the homeowner’s business, required a system which could cope with the high heating demands.  

The original system was a dated oil fired boiler. Not only was the system inefficient, noisy and took up a lot of space, it was also causing condensation and dampness, due to the flue passing through the inside of the property. The brief from the client was for a quiet and compact system which would heat the entire home and outhouses efficiently, whilst also providing cost and energy savings.  

Due to the sheer size of the property, PHS required a highly efficient and reliable solution, which would be capable of working to the properties substantial requirements. Additionally, to ensure minimum disruption to family and office life, PHS Ltd sought a solution which would utilise the existing radiator and hot water cylinders already in place. As a result, the heating installer specified two Panasonic 12kW Aquarea Air Source Heat Pumps.  

PHS removed the oil fired boiler and a large 600 gallon oil tank, located in the outhouse, freeing up valuable storage space and negating the risk of oil pollution from the property. The two Aquarea heat pumps were then installed in a convenient location adjacent to the garage.  

“Our client is delighted with how quiet and efficient the Panasonic heat pumps have proved to be. Within the first year, the homeowner has made a 100%* saving on oil bills, and a noticeable reduction in running costs,” says Allan Lawson, General Manager at PHS. “We have worked with Panasonic many times in the past and have always found fitting the Aquarea range of heat pumps to be a fast and efficient process. Following the install, the results and payback our client is receiving makes Panasonic the ideal choice for both the installer and the homeowner every time.”  

Panasonic 12kW Air Source Heat Pumps form part of its popular Aquarea range. Boasting an impressive COP of 5.08, the Aquarea range of heat pumps are one of the most compact, versatile, silent, and cost-effective units available in the UK. The range features heat pumps from 3 to 16kW which have proven to make savings of up to 80% on heating expenses. Not only is Panasonic’s Aquarea range of heat pumps completely renewable and a cost-effective energy solution, but it also complies with current government incentives in the UK and Channel Islands, such as the Green Deal.

*100% savings were made in fuel and oil costs only.

Passive House, Poland


Aquarea air to water heat pump, Residential


A Panasonic Aquarea heat pump has been installed in a Procyon H1 passive house in Tychowo near Stargard Szczecinski, Poland. With an Aquarea heat pump, analysis has shown that energy consumption and heating bills can be reduced, often by between 50% and 80% in comparison to heating systems fuelled by LPG or oil. The environmentally-friendly Aquarea helps the building adhere to the rigorous, voluntary standard of passive house status, where energy efficiency is maximized and the building’s carbon footprint is minimised. This building in Tychowo is the only certified passive house in West Pomeranian Voivodship.

Tomasz Lenarczyk, Sales Manager for Panasonic, Poland, said: “Aquarea heat pumps are perfect solutions for detached houses (and in this case a passive house). They are fuss-free and residents do not need to invest in other infrastructure. Our products are easy to install and non-disruptive. More and more people are opting for ecological and energy efficient homes – rightly so. It’s the way society is moving, and for that reason, Panasonic has designed new models of Aquarea heat pump, which meet the requirements of low-energy buildings. Not only is this solution seen here environmentally-friendly, but from the owners’ point of view, it’s also a much more flexible and cheaper than a traditional gas boiler”.

About the building

H1 is a model of detached house designed by innovative construction company, Procyon. The building covers an area of 147m2 and consists of four rooms and a kitchen. The simple, clean design of the building is complemented with a gable roof.

The property in Tychowo, built in summer 2013 according to the passive house standard, is the first building in West Pomeranian Voivodship to be passive-house-certified by the Passive House Institute (PHI) in Darmstadt. This certification means that the building fulfils numerous requirements relating to construction processes, implemented solutions and energy consumption. For example,
passive houses must have good levels of insulation, an excellent level of airtightness, good indoor air quality and passive solar gains and internal heat sources.

According to the definition adopted by PHI, a passive house is a structure with a very low annual heating demand of approximately 15 kW/m2. Thermal comfort should be guaranteed by passive heat sources such as occupants, electrical appliances and incoming sunlight, and by significantly reducing the heat loss in a property.

The energy balance of the building is affected by many factors. For example, passive houses are compact in shape to minimize heat loss; windows should be south-facing or oriented toward the sunny side of the property; and interiors that require heat should be located in the central part of the building. It is also essential to use proper insulation materials of sufficient thickness for walls and roof.

Why is Aquarea a brilliant choice for passive houses?

The project team had to select the most energy-efficient and cost-effective home technologies in order to comply with passive house requirements and to complement the energy-conscious design of the building. Therefore, the characteristics of passive houses inevitably affect the choice of heating and cooling solutions. The objective is to maintain an optimal temperature for residents by heating the fresh air supplied to the premises via a mechanical ventilation system. Typically, project managers choose between a condensing boiler, heat pump and solar panels for the simultaneous provision of heating, ventilation and hot water.

The team selected a Panasonic Aquarea heat pump for the production of heating and hot water, thus maintaining the building’s energy-saving ethos. The heat pump is connected to a ventilation system and underfloor heating for maximum comfort and energy-efficiency.

An Aquarea heat pump specifically designed for passive houses

 This H1 property is the first of its kind in Poland, comprising an Aquarea heat pump and water tank with a capacity of 200 litres. The temperature of each room is individually controlled using an IntesisHome remote control system (via a PC or smart device), making the system flexible and able to adapt to residents’ needs and preferences. Residents can control the system from anywhere in the world, as long as they’re connected to the internet.

This Aquarea heat pump (KIT-SDF05E3E5), specifically designed for energy-conscious houses, has a capacity of 5kW (A7/W35) and high COP of 4.63 (at nominal condition 7°C outdoor temperature, heating water at 35°C). Thanks to the A-class circulating pump with an inverter+ compressor, the system helps to reduce energy consumption and heating costs, in comparison to traditional heating systems. The unit belongs to the Aquarea T-CAP series and is able to provide hot water up to 55°C. It is effective even in extreme temperatures (-20°C to 35°C), and if the outside temperature falls below -15°C, the efficiency of the heat pump reduces by 0.8kW only, making it an extremely reliable product.

How can Aquarea heat pumps reduce heating bills?

Procyon recently carried out some research to analyse how heat pumps could help save on heating costs. According to the findings, the annual cost to heat a square-metre to 20°C is approximately 3.7 PLN. Please see how this compares with other heating systems in the chart above. The chart shows that biomass-pellet is the only heat source cheaper than Panasonic Aquarea heat pumps. However, biomass systems are more complex and require a customer to buy and store fuel, replenish the tank, and regularly clean the furnace. Biomass systems also emit by-products of combustion into the atmosphere. In contrast, heat pumps are a hassle-free alternative which require nominal supervision.

Aleksandra Szejny, R&D Specialist at Procyon said: “As the calculations clearly show, by heating a 145 square metre house with natural gas, approximately 4500 kg of CO2 is produced a year. However, with a heat pump, no products of combustion are released into the atmosphere and electricity consumption is low. Panasonic Aquarea heat pumps are a high performing, energy-efficient and low cost heating alternative”.

Aquarea T-CAP

The attraction of a self-build project is that the owner can put more consideration into the products they specify, and explore how these solutions can benefit them in the future. It comes as no surprise that renewable technology is a high priority for self-build projects, and heating installers are seeing the attention turn from traditional heating systems, to solutions such as air source heat pumps and photovoltaic (PV) solar panels.  

Renewable technology has been a buzz word with end users for a number of years now. Thanks to the vast amount of information available online, and the various Government schemes available, consumers are becoming more knowledgeable on what renewable technology is.  This is an interesting development for installers, as it means that they are receiving more descriptive client briefs.  

For one forward-thinking family in Waterbeach, near Cambridge, building a modern family home from scratch enabled the design and specification of an all-encompassing heating and hot water system. Having investigated what the Renewable Heat Incentive entailed, the family opted to have an air source heat pump installed, and enlisted the help of MCS Accredited Installer, Eco Installer, who suggested a Panasonic Aquarea system.   

Eco Installer worked closely with local Architect, Freeman Brear, building contractor, Salmon Brothers, and the homeowner, to build and establish the ultimate eco-house.  The main necessities outlined by the client for a renewable heating solution were reliability, automation and ease of use.  

Renowned for its compact build, easy integration with other renewable technologies and consistent energy saving capabilities, Eco Installer chose Panasonic as the main heating and hot water provider for this new build property. Panasonic’s Aquarea T-Cap system is known for its constant capacity output, ensuring working noise levels are at a minimum. This was crucial to the homeowner, whose development was taking place in a built-up area where loud noises and disturbances would not have been greatly received.  

A 9kW Panasonic T-Cap Air Source Heat Pump was placed against the side of the house in the garden, along with a High Gain Cylinder and Buffer Tank hidden at the back of the garage. Once the Air Source Heat Pump was firmly in place, Eco Installer was able to integrate the system to enhance the capabilities of the properties newly installed under-floor heating, radiators, towel rails and hot water. This eco-conscious family also opted for Solar Photovoltaic (PV) Panels on the roof of the property, providing electricity with Solar iBoost and feeding excess heat energy from the PV array into the water tank for free.  

The project completed in January 2015, a mere five months after it began. The family has now moved into the property and is now benefitting from constant heating and hot water. As the Aquarea heat pump is MCS accredited, the homeowner is also reaping the benefits from the Renewable Heat Incentive (RHI), and every kWh of renewable energy produced.    

“For us, Panasonic’s Air Source Heat Pumps have always proved extremely reliable with little to no maintenance required once they have been installed,” explains Roland Gurner, Managing Director at Eco Installer. “The install itself is made quick and easy with its compact frame. This is a benefit to both us and the homeowner as it saves us both time and money. For a project which includes a number of renewable technologies, it is important to have a heat pump that works efficiently with other solutions. The Aquarea unit does just that. The end result is a fully functioning and intelligent heating and hot water solution.”

Make the most of RHI

Fife, Scotland

Aquarea air to water heat pump, Residential



In April 2014, the government placed a £650,000 fund into the Renewable Heat Incentive (RHI).

Already, almost 25,000 households across the UK alone have applied and started to benefit from the RHI. Thanks to the install of Panasonic’s reliable Aquarea 12kW Mono Bloc system, one family in Fife, Scotland, is now saving over £2,300 on annual heating costs.

Based in the small village of Balmullo in Fife, Scotland, an off-grid, medium-sized property relied on an old air source heat pump for an entire family’s heating and hot water requirements. This unique home had originally had all building materials imported from across Europe, in hope of producing the most energy efficient and sustainable home in the area. However, a combination of an old heating system, poor installation and product inefficiency, the homeowner had previously spent a costly £3,500 per year in running costs alone. This was reduced to £1,179 once Panasonics air source heat pump had been installed.  

The family wanted a system which was both energy efficient and environmentally friendly, enhancing their unique eco-home which had been built with a view of saving money and reducing their carbon footprint. It was also important for the client to make use of available government grants, such as the RHI. Therefore, heating technology needed to be eligible and MCS accredited.    

Local Panasonic PRO Partner and expert in renewable technologies, Eco Heat Renewables Ltd, chose Panasonic to facilitate the process of the RHI, supplying a “next generation”, sustainable and MCS Accredited Aquarea Air Source Heat Pump. This environmentally friendly domestic heating system from Panasonic offered a substantially improved performance in comparison to the previous system.    

After a site survey was carried out and detailed heat loss calculations were completed Panasonic’s high performance 12 kW Aquarea Mono Bloc (single phase heat pump) was selected to meet the demand of the property.  

Panasonic’s Aquarea range of air source heat pumps deliver tangible results for homeowners thanks to its quick payback in purchase and installation costs, along with enduring savings in energy and heating bills. Meanwhile, the Aquarea is popular with Installers due to its ease in installation and maintenance. Additionally, Panasonic’s Aquarea Mono Bloc adapts well in an existing installation with a boiler backup, and in new applications with under floor heating, low temperature radiators or even fan-coil heaters. This range holds many energy saving qualities such as an optional smartphone control for better heating and cooling management, and the ability to produce up to four times the amount of energy per kW consumed in comparison to conventional heating methods. For these reasons, Panasonic’s 12kW MonoBloc Aquarea system was the clear choice for all heating and hot water requirements for this property.  

“Our client wanted a Panasonic heat pump as they felt that this was a strong, globally recognised brand, renowned for innovation, ease of use and reliability.  They also wanted the system to be installed by a local company that was recognised as a Panasonic Pro Partner.” says Jim Russell, Company Director at Eco Heat Renewables. “We installed Panasonic’s Monobloc unit in June 2014.  Feedback from the customer has been extremely positive and the family is delighted with the savings that were made immediately upon installation, and then continued in the following year.”  

Within six weeks of the installation, the homeowner started to receive payments of £850 annually from the RHI. This would then continue for a period of seven years. In total, the £6,000 received from the RHI payments will cover 70% of the total install cost by itself.  

As a result, Eco Heat Renewables successfully matched the clients brief and expectations. The family have lowered their original, daily running costs from £10 per day to just under £4, making savings of a massive 65% (£2,300 per year) and there has also been a substantial decline in carbon emissions.

French Winery


VRF, Others


Gennevilliers, France, 30th April 2014 – A winery based in the small village Boutiers-Saint-Trojan, France, is benefitting from a Panasonic VRF system which supplies exact temperature requirements for the wine making process and is achieving outstanding results.

As many wine connoisseurs will already be aware, the winemaking process is a delicate and controlled art. The pressures, pumps and presses, and most importantly, the heat, must all work to precise figures in order for a high quality product to be made.  

The winery owners had been using electricity to power the coolers required for the important fermentation process. This traditional method proved inadequate with fluctuating power supplies that provoked power cuts and affected the smooth running of the harvest.  

A temporary solution was found with the rental of a generator, but this was an expensive and short term solution. A group study was conducted, to compare gas and electricity sources for the most efficient units in terms of power and cost.  

With the results landing in gas-powered favour and with a pre-existing gas supply on the winery site, winery consulting firm, Vinithermo Consulting, specified Panasonic’s ECO G High Performance VRF System as the ideal solution.  

Panasonics VRF range is the market leader in the professional heating and cooling market. All models are noticeably easy to install and quiet to run, whilst maintaining good thermal control and a particularly high level of performance. Its annual operating costs are particularly low, suggesting a real alternative to systems running on electricity.  

Panasonics ECO G System not only works as a power supply to the wine chiller, but the engine, which is fuelled by natural gas or LPG, is also used as a heat generator for this project. The heat generated by the operation of the engine is retrieved using a specific exchanger. This is then used to preheat the domestic hot water used by the winery owners.  

"The transition from cooling to heating is performed quickly and without complication,” says winery owners, Serge Renaud and Damien. “The installation has worked throughout the harvest period of 2013 to the highest levels we have achieved and offered a good level of performance. Huge gas and energy savings have already been made in our first harvest since installing this unit with an expected return on investment being achieved within a short three years. ”

Cornella de Llobregat

Barcelona, Spain

Aquarea air to water heat pump, Residential, Public buildings


A new building, housing 84 apartments in the municipal city of Cornella de Llobregat, Barcelona, has seen each home individually fitted with Panasonic’s Aquarea air to water heat pump system to achieve a ‘B-class’ energy rating for the entire building.  

The new housing development compromises 84 homes covering six floors, one commercial property, parking and storage space on the ground and second floor.  

For each of the six floors, 14 apartments have been built around a central courtyard, with access to a perimeter corridor. Behind the exterior, modern architecture and colourful design of the building, the developers required the building to incorporate the parameters to achieve a high ‘B’ energy rating.

 The project developer was ‘IMPSOL’, a public entity that economically depend on the metropolitan area of Barcelona.  

In order achieve this particular energy rating, the heating, ventilation, air conditioning hot water systems needed to be cost and energy efficient enough to run an entire residential building complex. Initially, a centralised gas boiler and a cogeneration system were envisaged for this project.  

However, after careful thought, it was decided a system which implemented renewable technology would be better suited. An individualised heating and Domestic Hot Water (DHW) system that would use the latest heat pump technology to heat water was required. Choosing this second option meant that, due to the aero thermal renewable energy technology offered, the developer would not have to install solar panels for hot water production which requires the Spanish legislation.

There were several reasons why IMPSOL specified a DHW system instead of the original idea of a centralised gas boiler. These included:
• The performance improvement by an air to water system, particularly for cold climate housing
• Centralised boilers require numerous adjustments and tuning which involves extensive occupation of the dwellings
• A centralised community facility requires consistent and expensive maintenance  

For a system that would achieve all renewable technology and DHW requirements, whilst ensuring an energy rating of ‘B’ would be reached, the developer looked to Panasonic’s Aquarea system. Not only are these units infamous for energy efficiency, high COP levels and working to ideal temperatures, but it produces aero thermal, renewable technology, widely recognised by European Directive 2009/28/EC.  

Meeting the strict criteria set by IMPSOL, Panasonic’s Aquarea systems allowed each home to benefit from excellent heating and cooling aspects. At the same time, these systems were affordable and met the regulatory Spanish requirements for renewable energy inputs in the production of DHW and CO2 emissions.

Panasonics Technical Services and Project Managers from the City of Cornella de Llobregat organised a clever system to integrate energy saving measures across the residential complex. This included: implementing a Panasonic Aquarea System, increasing insulation and executing cross ventilation in all apartments.    

As a result, the desired energy rating was obtained, with a system that offers even more comfort to homes and, in turn, reduces maintenance costs. This clever system has also proved valuable for IMPSOL. The properties are of a higher value than anticipated, as homeowners enjoy the high energy efficiency and full air conditioning and heating system within each property.

Based around the concept of a townhouse, the Reciprocity house adapted seamlessly into the context of an urban-French home offering the space and ability to perform as a fully functioning house on either one level or up to four floors.  

The envelope of the house was designed to provide thermal insulation, whilst a passive standard "sun shading" provided simultaneous climate protection and energy production. Other energy saving facilities applied to this property included 20 mono-crystalline modules on the roof-terrace, with a total capacity of 4.8 kWp, which were attached to a galvanized steel chassis at an inclination of 18°.  

"When we were contacted by the team, while the house existed only on paper, we did not hesitate to join them in this adventure,” comments Marie Giraud, from Panasonic Heating and Air Conditioning France. "We are very proud of this award and offer our congratulations to the entire team involved in The Reciprocity House."  

Inspired by the original American Solar Decathlon, the Solar Decathlon Europe was an international competition that united universities and colleges from around the world to design, build and develop full-scale, fully-functional and affordable solar homes.  

The international judging panel inspected each entry on its energy-saving aspects, environmental transition density, simplicity, cost, mobility, innovation and contextualisation.

WDS Call Centre

Bournemouth, UK

VRF, Offices


Panasonic was called upon by Woodhouse Environmental Services Ltd to provide equipment for call centre giant, WDS, to retrofit its busy offices with an energy-efficient Heating, Ventilating and Air Conditioning (HVAC) system. Working against strict time and space constraints, Panasonic’s VRF systems coupled with large ducted and wall mounted indoor units were specified for a quick, simple and energy efficient install.  

WDS negotiated with the building owners, St Modwen Properties PLC, a multi-million pound property development and investment company, to redevelop one of three buildings at the Discovery Court Business Centre in Bournemouth.  

With the brief to remove and replace the old, existing system with a high-performance, easy-to-install HVAC system, the design and build contractor, Woodhouse Environmental Services Ltd, required a product that offered a large selection of different units, providing a maximum performance system to cater for this large building.  

WDS Call Centre (a part of the Xerox group) provides customer service solutions to some of the world’s best known technology and communications brands including Tesco mobile, Google and many other blue-chip brands.  

This complete system would need to cater for the high density office, providing exceptional heating and cooling efficiencies whilst maintaining close conditions, introducing continuous fresh air and removing stale exhaust air, ensuring a comfortable work environment at ideal temperatures. The install was to be undertaken whilst the tenants were still in residence.  This meant that it was imperative for staff disruption levels to be kept to an absolute minimum.  

Woodhouse Environmental Services initiated a fast track install programme between June 2013 and October 2013, splitting the renovation into three phases to cover each ‘zone’ of the building, satisfying a tight budget, and remaining within the allocated time.  

In the first phase, Panasonic’s integrated VRF and heat recovery ventilation systems were installed to replace the existing air cooled chilled water system operating on R22 along with a ducted fan coil system, which no longer provided the efficient and reliable service in this demanding application. Specifying Panasonic’s VRF unit made for an all-round easy-to-use system, whilst it’s clever, innovative integrated technologies meant wasted energy was avoided and significant savings could be made on the buildings annual energy bills. Additional extras including an energy monitoring touch screen control with multi-zone temperature adjustment, making this Panasonic system the efficient, ideal replacement that was so desired.  

As part of the second and third phases, Panasonic’s ducted indoor and wall mounted units were also incorporated in the building refurbishment. Not only were these systems integrated to provide fresh air input and stale air removal, but they also fitted the outlined noise criteria. Panasonic was able to supply all of this equipment on short notice so as not to delay the project.  

As a result, Panasonic proved to provide the most energy efficient units on the market, suitable for this large-scale project. With approximately 250 members of staff based in each zone, the quick turn-around, replacing the old systems and fitting brand new Panasonic equipment, meant staff were able to move straight back into the refurbished offices immediately on completion.

Sunprime Atlantic View

Canary Islands, Spain

VRF, Hotels


Specifying a system which can provide heat and hot water, supply sufficient air conditioning to cool hotel rooms, spa facilities and communal areas, whilst still keeping energy costs low, is a regular challenge confronted by hotel chains across the Canary Islands.

The exclusive Sunprime Atlantic View resort, owned by Thomas Cook, has 229 rooms plus full spa and swimming pool facilities.  Holding an EU-Eco Label as testament to its commitment to the environment, Sunprime had set a goal to reduce its energy bills by 25%.  

Its current heating and cooling system had proved to be extremely costly.  Seven years ago, two large chillers had been installed to cool the rooms, whilst a gas boiler system heated the water, swimming pools and spa centre. Both systems were proving to be inadequate, with high running costs for the hotel plus customer satisfaction, claims about the fluctuations in water temperature for the swimming pools.  

In search of a more cost and energy efficient system, five of Panasonic’s ECO G VRF systems were specified as they met all of the hotels heating and cooling needs via one simple solution.

Extensive development and research into the technology behind Panasonic’s ECO G system means these units use an engine cooling system, to heat water at up to 75ºC, covering all heating demands for the hotel. This includes all the rooms and most impressively, to heat the spa and outdoor swimming pool facilities, keeping temperatures at a consistent temperature of 28ºC. Additionally, Panasonic’s ECO G systems offered the ultimate ease of maintenance thanks to its remote monitor and maintenance software, which allowed the Maintenance Manager to control the status and temperature of the hotel from any site.

“Not only did the Panasonic system enable all of our heating and cooling requirements to be fulfilled through one compact system, but the installation itself was extremely quick, meaning the normal operation of the hotel was not affected,” explains Angel Hernandez Ramos, Resort Manager Sunprime Resorts. “Our customer satisfaction ratings have improved as a result of installing this system, which has meant an extremely quick return on investment for us.”  

This new solution from Panasonic provided the hotel with energy savings so quickly that it was decided to replace the heating, ventilating and air conditioning (HVAC) systems in other Sunprime hotels across the Canary Islands, including Hotel Sunprime Riviera Beach & Spa, Arguineguín.

Within one year, Sunprime Atlantic View Hotel had made savings of 24% in electricity consumption and 32% in gas consumption, surpassing its original goals, thanks to a more efficient system by Panasonic.

Family Home, Lombardy

Lombardy, Italy

Aquarea air to water heat pump, Residential


A homeowner in Lombardy, Italy, is reaping the rewards of using not one but two renewable energy sources to heat their home and produce hot water. Thanks to Panasonic’s intelligent technologies and the ease at which they can be integrated with other systems, an Aquarea 7kW-heat pump is harnessing the energy from the property’s 3kW-solar panels on the roof to ensure energy efficiencies and financial savings.  

The resident had wanted to make the most of the energy produced by the photovoltaic panels, and made enquiries about whether it was possible to link the panels to a heat pump.  An Aquarea heat pump was installed, and the two technologies are synced and managed using a Heat Pump Control Manager (HPM). The HPM can be adjusted to optimize the heat output of the heat pump, as a function of the independent production of energy.  

Thanks to the HPM, it is possible to manage and exploit the overproduction of electrical energy – as captured by the photovoltaic panels - and store it in the form of hot water by using the Aquarea heat pump.  

This project is a brilliant example of how considerable financial savings can be made by integrating technologies in the home. Through making the most of renewable and reliable energy sources such as energy from the sun, households are able to guarantee a warm and comfortable home for years and years to come, without having to worry about increases in energy prices.   

The heating system uses an Aquarea Bi-block High Performance 7kW (High Connectivity Hot and Cold), which is connected to solar thermal and photovoltaic panels. In this configuration, when the solar panels produce sufficient energy to cover the consumption of the heat pump, the water temperature stored inside the tank increases up to 55°C. For this particular installation, an outdoor unit was installed in the courtyard of the property and the hydronic kit in the utility room below, along with the HPM.  

Alessandro Ferrara, Regional Key Account for Panasonic said: "Our Heat Pump Manager is the only programmable controller on the market that can manage a heat pump based on photovoltaic energy production.  This product offers the market several benefits including speed of installation, efficient and well-integrated installations and commissioning of the system”.  

Using the HPM control system enabled the owner to cut heating costs while maintaining high performance heating and cooling even in adverse weather conditions. The HPM also enables the homeowner to monitor the Aquarea remotely.  

Gaetano Nigro, Regional Key Account for Panasonic, said: "The homeowner has been more than satisfied with the choice of Aquarea and HPM. He said he chose Panasonic because he wanted the reliability of a well-known brand. The ease of connecting the solar panels and Aquarea heat pumps was also a key motivation."

Family Home, Cumbria


Aquarea air to water heat pump, Residential


As homeowners begin to move away from oil, LPG and electric heating systems, there is a high demand for a cost effective and environmentally friendly solution. A Cumbria-based family opted to switch to Panasonic’s Mono-Bloc air source heat pump just over a year ago and have since benefitted from savings of up to £1,200.  

This seven bedroom house in a rural community outside of Cumbria had been relying on an oil tank to provide heating. With the UK experiencing colder winters, the oil tank required more regular oil refills. This, combined with rising oil prices, prompted the homeowners to look for an alternative solution which would provide financial and environmental benefits.  

In November 2012, air source heat pump specialist, Heacol Ltd, was enlisted to provide an energy-saving solution. It was decided that the installation of a heat pump was imperative for economical heating to be achieved. The new heat pump would assist the existing oil boiler in creating a long-life solution with high energy savings.  

Panasonic’s 12kW Aquarea Mono-Bloc air source heat pump was specified by Heacol Ltd due to its  low start-up current and operating power (compared other heat pumps), making this system particularly suitable for this application which was bound by the rural electricity grid.   The Mono-Bloc system works with the oil boiler to provide hot water and heating throughout the entire house, whilst using minimum energy consumption.

This is achieved by the high temperature heat pump pulling fresh, clean and more importantly, free air and transferring this into sustainable energy to heat the home.  Panasonic’s Aquarea systems are proven to reduce energy costs and can achieve a COP of 4.74*, as well as energy consumption and CO2 emissions.  

The Panasonic’s Mono-Bloc unit proved to substantially lower the cost of the families heating. In the 12 month period following installation, the oil tank had not been needed to be refilled at all.  

“The homeowners are extremely happy with the Panasonic Aquarea Mono-Bloc system as they are achieving impressive energy savings,” explains Brendon Uys, Managing Director of Heacol Ltd. “The benefit for us, was that the system was extremely easy to install, with a simple controller and programming method. The system offers long-term stability and is extremely reliable.  

As a result of installing this highly efficient heating system, which has excellent seasonal performance, the homeowners are now able to leave their heating on continually throughout the winter. Even with continuous energy use, cost savings for the homeowners have reached £1,200 within the first year of installation.

MCS certification was issued to the property at the end of the project.

GE Aviation

Bristol, UK

Commercial, Offices


For many large, commercial businesses, finding the perfect solution to ensure required heating and cooling requirements are met, whilst keeping costs low and energy savings high, can be a lengthy process.  

For world-leading jet and turbo engine provider, GE Aviation, the solution could not have been simpler when specifying Panasonic’s PACi range of commercial units.

GE Aviation provides the crucial components and integrated systems for commercial, military, business and general aviation aircraft, and ship propulsion applications.  

Bristol-based installer, Swift Express Maintenance Ltd, had worked with GE Aviation 20 years previously when the initial Heating, Cooling, Ventilation and Air Conditioning (HVAC) equipment had been installed. Now, this system was proving to be dated and inefficient to work across the 24/7 operation required.  

Swift Express was asked to design and specify a solution with good efficiency capabilities, working to high demands and to the specific temperatures required for the heavy duty work carried out at this aviation headquarters. Therefore, identifying a reliable brand and product were essential for this install to avoid regular troubleshooting and repairs.  

Panasonic's recently developed PACi range of indoor and outdoor commercial units proved the ideal choice for this application. Eight PACi Elite 14kW units were installed outdoors, whilst four under-ceiling units and four wall-ducted systems were established indoors. A further 28kW of PACi cooling technology have been specified to be installed within the factory.

Panasonic’s PACi Elite group of commercial air conditioning systems are ranked as one of the top COP values within the industry. Not only do the high efficient R410A refrigerant abilities result in the lower operating costs and reduced CO2 emissions that GE Aviation had specifically required, but all systems belonging to the PACi range ensure the ultimate ease in install whilst meeting the necessary safety approvals ensuring the utmost in quality and safety.  

Due to the delicate environment and equipment handled by GE Aviation, a fire watch of 4 hours is required for any hot works, so Swift Express opted to use the revolutionairy Reflok aluminium piping system with the Panasonic equipment.

As part of Panasonic’s commitment to health and safety, all air conditioners undergo strict quality and safety tests before sale. This rigorous process includes obtaining all necessary safety approvals, to ensure that all air conditioners we sell are not only built to the highest market standards, but are also completely safe.  

Initial renovations started five years ago when a 50kW air conditioning system was installed. The first phase of this new installation began in August 2014, which included the installation of 30kW of Panasonic PACi Elite air conditioning units. The Remaining 70kW of equipment was installed in the second phase, which started at the beginning of October 2014 and was completed by the end of the same month. So far, the installation has proved to require minimum in maintenance.  

“Since the initial install five years ago, Panasonic’s heating and cooling systems haven’t stopped or had any problems,” explains Josh Muschamp, Business Development at Swift Express Maintenance Limited. “We have worked with Panasonic for many years and have never incurred any technical problems with its kit. This is why we chose to specify their range of PACi air conditioning units for this prestigious project. We needed something we could rely on to work to at high efficiency capabilities without requiring us to visit and fix every six months. We needed something that would be easy to install and would withstand compression bonding. With this in mind, for us, Panasonic was the obvious choice.”

Panasonic 'Smart Home'

Tokyo, Japan

Aquarea air to water heat pump, Domestic air to air heat pump, Residential

Smart House

• The Panasonic 'Smart House' shows visitors how to live in a house with zero emissions.
• Save, create, store and manage energy are the key factors to an efficient home.  

The world is struggling to reduce emissions. However, changes in technology allow homeowners to achieve a zero emission lifestyle in their home.  

Panasonic envisions a future in which all families can almost completely eliminate CO2 emissions through the use of efficient appliances and the combination of solar power generation, fuel cells and storage batteries. Panasonic demonstrates this in a 'Smart House' in Ariake, Tokyo. Visitors are invited to experience what it would be to live in a house with practically zero emissions.

The Panasonic ‘Smart House’ highlights the four key factors to being energy efficient – saving, creating, storage and power management.

Save energy  
Whether you save energy, depends on the appliances which are used in the home. These days it is easy to find the most energy efficient product as most of them have an energy label.  

Panasonic has proposed that by 2016, over 80% of its labelled models will achieve one of the first two energy efficiency classes. This is already the case for some of Panasonic’s products. For example, its refrigerators have an insulation panel called U-vacuous, which allows twenty times more insulation than traditional panels.  

Panasonic’s HVAC (heating, ventilation and air conditioning) products also support this development.  It air conditioning units have an energy saving technology called ECONAVI.  This is a smart sensor system which is capable of controlling the intensity of sunlight, movement, activity level and human absence, automatically adjusting the cooling output and saving energy efficiently. This saves energy of up to 38% in cooling mode and up to 45% in heating mode.

Panasonic also used a system of sensors in its washing machines. This is the 3D sensor that adjusts the rotational speed to optimize the effect of the fall in the drum and maximize water and energy.  

Meanwhile, the Panasonic dryers have a heat pump, based on the same principle as heating with an air conditioner.  

Panasonic’s Inverter technology ensures optimal performance while minimizing energy consumption. In air conditioning systems for example, inverter technology allows the system to quickly reach the desired temperature and then keep it all the time increasing energy savings and comfort. Washers, dryers and refrigerators also feature Panasonic inverter technology.

Lighting is also very important in saving energy in a home. Using a Panasonic LED bulb instead of a traditional light bulb, results in energy consumption dropping by 85%. In addition, LED bulbs have a service life up to 40 times higher than incandescent bulbs.

Create energy  
It is important or a home to have the tools to generate energy by itself with minimal CO2 emissions. A good example is solar panels.

Panasonic aspires to be one of the three leaders in the field of solar panels by 2016.  

Panasonic Home Solar Power Generation System HIT are able to:  
• Offer one of the highest ratios of conversion efficiency: 24.7%.
• Provide energy production 5% higher than conventional solar panels.
• Ensure a high performance even in warm weather conditions.
• One of the most reliable products in the market, with a failure rate of 0.0036%. Of the 3.3 million solar panels that are sold in Europe, there has only been 120 cases requiring revision.  

Another tool for energy is the fuel cell for home use. Fuel cells are a highly efficient method to generate electricity through an electrochemical reaction between hydrogen and oxygen. Furthermore, the remaining residual heat of reaction is used to generate hot water. This system can save around 1.5 tonnes of CO2 emissions annually, compared with a house that runs on electricity and heat with a heating system with gas. 

Panasonic was the first company in the world to sell fuel cells for use in the home.  It is called ENE FARM. Since its launch in May 2009, Panasonic has sold 31,000 units in Japan (up to September 2013). In Europe, Panasonic has two R & D centers located in Langen (Germany) and Wales (United Kingdom) that focus on developing residential fuel cells for the European market. Although not yet marketed in Europe, these research centers work closely with utility companies related to energy.

Store energy  
The storage of energy in a home is achieved through a combination of solar power generation, fuel cells and storage batteries.  

Devices such as Panasonic batteries lithium-ion, allow homeowners to conserve energy and ensure stable power supply.  

In June 2012 Panasonic started mass production of a set of lithium-ion compact, safe and long lasting systems. Thus, Panasonic has become the first company to mass produce a system of its kind in Europe.

Manage energy  
It is important to be able to control when, how and how much energy is consumed.  This is why the smart homes of the future integrate systems for managing home energy such as Panasonic’s Smart Home Energy Management System (SMARTHEMS). The main features of this system, which incorporates AiSEG (Artificial Intelligence (AI) and Smart Energy Gateway (SEG), are:

 • Real-time measurements of the consumption of electricity, water and gas. For electricity, the monitor displays the current state and the CO2 balance of the entire house, estimated electricity charges as well as the ability to generate energy through solar energy or fuel cells. The different types of data, including the amount of charge of storage batteries, can be monitored through televisions, computers, smart phone screens and other displays.  

• Artificial Intelligence (AiSEG) and Smart Energy Gatewway (SEG) is the control center SMARTHEMS, which allows connection and control of electrical equipment and appliances in the home, and helps to increase energy savings. 

• The cloud will play a key role in the field of energy. The cloud is essential not only to connect the devices, but also to anticipate and respond to consumer needs - both at home and outside. Panasonic has partnered with some of the world's leading IT companies to convert this vision into reality. In fact, Panasonic and IBM have agreed to work together to evaluate the commercial and technical appliances connected future in the cloud value.

On 6th February 2014, an experimental, next-generation convenience store was opened as part of a collaborative project between Lawson, Inc. and Panasonic Heating and Cooling at the Panasonic Headquarters in Moriguchi, Japan.

In April 2013, Panasonic and Lawson launched their collaborative project in which they shared their retail and technology visions.  The store is directly managed by Lawson, and is operated in the same way as a regular Lawson store whilst utilizing Panasonic technologies.

With three main goals, both Panasonic and Lawson wanted to investigate ways in which they could fuse their businesses together and offer:
Eco-friendly solutions: via the introduction of equipment and systems to enable reduction of power usage by 50%; HIT solar panels, lithium-ion storage batteries, CFC-free showcases, LEDs/lighting control and air-conditioning/ventilation control Convenience with the aid of ICT: Alternate ways of sales promotion, such as using digital signage; through the introduction of a camera-based in-store marketing system Healthy lifestyle choices: By introducing in-store cooking appliances; through the installation of a relaxation corner that offers a sense of comfort to customers Panasonic and Lawson were able to trial the environmental, store operation and security alternatives in a public environment. This provided Lawson the opportunity to use this outlet to experiment with ways in which to strengthen its customer-orientated business, whilst at the same time utilising a range of equipment from Panasonic including air source heat pumps, air conditioning systems and air curtains, putting them into practice in a retail environment. 

The two companies will judge the effectiveness of this concept store based on actual operational data, enabling them to make improvements and then extend the accumulated knowledge and know-how to Lawson stores across Japan as a result of the experiment.

"Lawson and Panasonic decided together to create a convenience store by using Panasonic's technologies to address various challenges we face in serving our customers daily,” explains Lawson COO, Tamatsuka. “Throughout this experiment, we have been faced with many challenging requests for Panasonic and we have greatly appreciate the positive approach they constantly showed whilst solving these demands."

Enokido, Panasonic Executive Officer said, "Environment, health, and information and communication technology (ICT) are important aspects of the food industry which are often exploited. This experimental store allowed both companies to enhance practice in all of these areas, and work towards a customer engaging and innovative business. We hope to keep evolving our technologies and services for an advanced future in home technology sector."

Family Home, Derbyshire


Aquarea air to water heat pump, Residential


A family in Sudbury, Derbyshire is benefiting from savings of up to £100 per month after Trent and Dove Housing Ltd and contractor, J Tomlinson replaced their existing solid fuel boiler with a Panasonic air source heat pump.  

Trent and Dove Housing Ltd provide affordable housing for rent and part ownership across East Staffordshire and South Derbyshire.  One of the housing association’s aims is to supply renewable technologies to provide its tenants with more efficient, cost effective systems.  Working with J Tomlinson, Trent and Dove Housing has tried and tested various options including photovoltaic, solar thermal and a number of air source heating installations.   

The housing association was presented with an opportunity to provide a family in Sudbury with a more efficient heating system, and J Tomlinson specified Panasonic’s T-Cap 9kW Mono Bloc Air Source Heat pump.  

Mrs Collyer and her family originally had a solid fuel boiler which provided both heating and hot water.  While they were reasonably satisfied with the system, they were concerned about the mess and the time involved in cleaning and maintaining the system.  There was limited control over the solid fuel boiler, which also made it extremely difficult to control the heating. When the option to change to an air source heat pump arose, Mr and Mrs Collyer were more than happy to proceed.  

The installation commenced on the 1st November 2013 following an initial survey. During the survey, the tenants were advised about the process and benefits of having a new system installed. The preparatory work was then undertaken by J Tomlinson. A base was formed for the external unit and a new power supply fitted. A lamp was also installed into the outside storeroom where the new cylinder would be positioned.  The J Tomlinson team visited the site three days later and installed the Panasonic Aquarea unit.  The whole project took seven days to complete, with a supervisor from J Tomlinson and Panasonic engineer commissioning the air source heat pump on the 7th November 2013.  

“We are very pleased with the end result,” commented Neil Knightsmith, Contracts Manager at J Tomlinson. “The system was easy to install and is now generating great savings for the tenants.  There is an evident increase in demand within the social housing sector for energy efficient and easy-to-manage heating systems. We are experienced in replacing expensive fuel or oil boilers, and providing alternative renewable heating solutions. Panasonic makes this daunting move for customers an easy adjustment. The Mono Bloc T-Cap system is compact, requiring minimum space which is often an issue in social housing.”  

J Tomlinson team visited the property approximately six weeks after the installation, and were delighted to find out that the tenants are already saving between £10 - £20 per week on fuel costs.  This saving is attributable to the Panasonic Aquarea heat pumps being an efficient, cost effective and environmentally friendly solution compared to using solid fossil fuel boilers, oil and other electrical systems.   Panasonic’s air-to-water Mono Bloc Air Source Heat Pump is designed specifically for the UK market, where space is limited and high performance is required.  The outdoor and indoor units are combined into one easy-to-install and compact enclosure, saving time and installation costs. With a COP of 4.41, up to 78% savings can be made on heating expenses.

Type of project: Refurbishment

Installer Company: Pick Everard.
Year installation: 2012

The ailing chiller system serving the National Grid’s Hinckley critical call centre needed to be replaced.  National Grid needed a reliable and cost-effective solution.

Project Challenge:
 The Hinckley plant houses the highly important gas leak call centre that runs 365 days a year, 24 hours a day. It was crucial for the system to not only be dependable, but also be highly energy efficient.

The Pansonic ECO-G system installed allowed for more efficient control and performance. The National Grid site’s existing system of two chillers was replaced by seven Panasonic ECO-G’s. This technique of using multiple systems provides a much higher resilience compared to only one or two units. If a fault in one arises, the combination of heat pumps ensures that it is able to provide continuity of service.  

Building Energy analysis: 
The new ECO-G system installed on site has been a very straight forward transition. Not only do the units provide continuous service to the site, they have also allows the costs involved in running the units to be significantly reduced.

Hotel Claris 5 * GL


Commercial, VRF, Hotels

ECOi 3w

Housed in a building built in the year 1883, neoclassical style, was one of the first palaces that were built in one corner of the District of l'Eixample in Barcelona. The 5* Grand Luxe hotel, which opened its doors in 1992, integrates the façade of the old palace with a modern glass structure. In 2012 the building replaced its existing air-conditioning system with Panasonic’s ECOi system. The 120-room hotel also has a gallery of Egyptian art from the collection of Jordi Clos.

Challenge of the project
The challenge presented by this project was to replace an existing VRF system without affecting the normal activity of hotel. The main objectives were to reduce running costs, provide a more comfortable atmosphere with more precise temperature control, and quieter operation for guests. In addition, the property required excellent after-sales service, 24 hours a day, 365 days a year.

The solution
The heat recovery system is ideal for a hotel of this category. A smart combination of 2 pipe and heat recovery units significantly reduced the investment costs, without affecting the requirements of comfort. Thanks to the modularity of the system ECOi, the installation was performed plant-by-plant without affecting the normal activity of hotel.

The integrated system control was provided by the KNX/EIB interface and in addition, a central touch panel with web server (CZ-256ESMC2) was installed for centralized system control

Café 40


VRF, Restaurants


40 Café is the first café restaurant belonging to Los 40 Principales, in Spain's popular music radio station. The installation is within the basement of an old building in one of the busiest streets of Madrid. 40 Cafe, aims to become a new icon of nightlife in Madrid.

Challenge of the project
There were several challenges to implementing this project. The first was the power limitation in the building. Despite being in the Centre of Madrid, there was a restriction on power to run conventional HVAC installation. Another major challenge was the opening date. The tight deadline was a requirement to meet the demand of the owners. Outdoor units were installed at roof level with the help of a crane. Due to the limitations of restricting Street access and the imposition to residents of the building, the external installation was carried out in just one day available prior to opening.

The solution
ECOg, the gas powered VRF, was the ideal solution to overcome the power limitation of the area. The system combines seamlessly with Panasonic’s VRF indoor units and allows additional connection to a hydronic system. Panasonic pledged delivery of the units for the only day in which the crane could be used, in spite of the fact that the systems still had to be produced. The installation date was
just 2 months after being awarded the project. This was all made possible thanks to the involvement of various departments as well as Senior Management, highlighting Panasonic’s commitment to meet customer needs.

A touch panel with PAIMS management (CZ-256ESMC2), was installed for centralized air conditioning system control, including PC software and web server interface.

Nearly 700 homes are already equipped with Panasonic’s Aquarea; the most comprehensive, versatile and cost-effective range of air-to-water heat pumps on the market.

Trecobat has chosen equip their customers’ homes with the Aquarea Monobloc 6kWh. The decision was based on a combination of ease of installation and commissioning, and the unmatched performance of the Aquarea Range. Particularly compact, this new 6kWh Monobloc model only comprises of an outdoor unit, instead of the extra module usually needed inside the home. This, added to the minimal requirement for accessories, provides the home-owner with a space-saving heating solution and saves installation time for the contractor.

BBC homes are particularly well insulated regardless of their size and therefore do not require high-power heating solutions. Able to achieve a COP rating of 4.74, despite its low consumption capacity, the Aquarea 6kWh Monobloc was chosen as an ideal hot water and heating solution due to its impressive heating and energy efficiency.

With the Aquarea Monobloc all components are combined into one unit: the heat exchanger, a 3-speed hot water circulating pump, 6 litre expansion, safety valve, pressure gauge and 3kW electrical resistance. This together with its proven reduced noise impact ensures maximum comfort even when outside temperatures drop to -15°C. The Aquarea range features heat pumps from 7 to 16 kW, single and three-phase alongside stand-alone and split-units. These high-efficiency heat pumps are designed to also provide cooling in summer.

 In combination with the new Panasonic HR200 sanitary hot water tank, Aquarea units can deliver hot water at a temperature of 55 °C, even at outside temperatures as low as -15°C. The HR200 tank is specially designed for connection to heat pumps, features a 1.8m² surface and is extremely efficient. It therefore ensures that hot water production is conducted in the most energy efficient way.

Carluccios Restaurant


Aquarea air to water heat pump, Restaurants


When restaurant chain Carluccio’s wanted to reduce their energy bills as well as their carbon footprint, it was the Panasonic Aquarea air to water heat pump system that provided them with the perfect sustainable solution. The implementation of an intelligent and effective system by FWP UK Ltd and Oceanair granted this project first place in the 2015 Panasonic PRO Awards under the category “best restaurant project”.

Installers, FWP Air Conditioning, together with distributor Oceanair were asked to install a system which would provide the desired volume of hot water, at the correct temperature while at the same time reducing energy costs. 

The attraction of super energy-efficient heat pump technology continues to grow and with the Government continuing to demand that businesses make big cuts to their carbon emissions, heat pump technology can help them to do so in an efficient way.  

Following a consultation with Carluccio’s, it was decided that their new site in the Meadowhall shopping centre in Sheffield would be the ideal location as it had the correct attributes for the installation of an air to water heat pump system.  Previous restaurants in the chain had been fitted with a more traditional 12kW boiler system.  

FWP installed a 12kW Aquarea T-CAP mono bloc unit which would allow  for the free air from the kitchen roof space to be transferred through condensing unit providing hot water at the optimum temperature.  With a high coefficient of performance (COP), for every kW of electricity the system uses, it provides 4kW of energy. This makes the Aquarea far more cost effective than a conventional heating system.

The Panasonic Aquarea air source heat pump converts the latent thermal energy found in fresh air into clean, efficient and sustainable heating and hot water. The conversion process (transferring heat from one place to another) is made possible by advanced inverter-driven technology that is similar to a domestic refrigerator.  

Meters were installed on the units to monitor energy use of the heat pump and immersion heaters since it was installed.  Commenting on the savings achieved, Tony Evanson from Oceanair said: “When Carluccio’s compared the Sheffield site to one of their existing restaurants of a similar size, the energy savings were considerable.  To heat the water for their Leeds restaurant cost £3782 whilst at the Meadowhall site the comparable cost was just £951. These sizable savings mean the site will see a return on investment in about 2 years and has achieved a COP of about 3.91.”

The T CAP (Total Capacity) line-up from Panasonic is able to maintain the same nominal capacity even at -15°C without the help of an electrical booster heater. T-CAP is also able to provide extremely high efficiency, whatever the outside temperature.

Compact mono-bloc air-to-water heat pumps are perfect for where space is at a premium as it was in the restaurant. Panasonic’s Aquarea 12kW mono-blocs combine the outdoor and indoor units into one package that is simple to install and easy to operate.  

Alison Stanton, Development Director from Carluccio’s said: “We strive for sustainability wherever possible right across our business and were keen to trial air to water heat pumps at our new Sheffield restaurant.  The results of the trial show us that we can achieve significant savings on our energy costs as well as reducing our carbon footprint.  We hope to now install Aquarea units at all of our new developments and potentially retro fit ASHPs to our existing 50 restaurants.”

BASF House


Aquarea air to water heat pump, Residential


Panasonic has partnered with Cool Planet, the renewable energy design and installation arm of British Gas, to deliver an industry-leading, eco heating solution for the BASF House, part of the ground-breaking Creative Energy Homes Project at the University of Nottingham.  

Cool Planet has retrofitted Panasonic’s pioneering Aquarea air-to-water heat pump technology at this showcase home for housing innovation and energy efficient design.  

The aim of the Creative Homes Project is to demonstrate compliance with the Code for Sustainable Homes using low energy principles from the PassivHaus standard. As one of seven homes constructed on Green Close, near Nottingham University’s Department of the Built Environment, the BASF House allows assessment of various low carbon and renewable energy technologies, providing the University with invaluable performance data. With its eco-efficient house, BASF demonstrates its competencies as one of the leading providers of products, systems and solutions for sustainable construction.  

Following the completion of testing on a biomass boiler, Cool Planet installed a 9 kW Aquarea monobloc unit in the BASF House in spring 2011. The installation was completed quickly and efficiently, without Cool Planet even having to change the property’s hot water cylinder.  

“I’ve really enjoyed working with the partnership of Panasonic and Cool Planet on this retrofit project” says Gill Kelleher, Project Manager for the BASF House. “From day one they’ve got to grips with the unique technical challenges and installed a simple to understand and operate ASHP (Air Source Heat Pump) solution whilst not forgetting to give outstanding customer service that everyone expects from a company like British Gas”. The Aquarea unit is proving itself an efficient performer. It serves the 2-storey dwelling’s wet radiator system and is capable of raising the water temperature within the hot water cylinder from 27oC (typical overnight standing temperature) up to 43oC (typical acceptable hot water temperature) within 1 hour.  

Because it uses air as the energy source, Aquarea also sets the standard for air-to-water heat pump energy efficiency. It can provide fuel bill savings of up to 78% compared to direct electric heating.  The system generates a COP of 4.74 which means that for every kW of electricity consumed, it returns 4.74 kW of energy, i.e. 3.74 kW more than a conventional electric heating system which has a maximum COP of 1.   Post graduate students living in the BASF House are able to monitor and control the operation of the Aquarea system through a special touch-panel Web-brick display interface.  

Xiaofeng Zheng, Nottingham PhD student, adds “We’re very impressed with Panasonic’s Aquarea air-to-water heat pump. We were surprised at both its intelligence and ability to make our life as tenants easier. I can’t believe how quiet and easy it is to control.” 

Panasonic’s Aquarea is the most comprehensive, versatile and cost-effective range of air-to-water heat pumps on the market. It features heat pumps from 7 to 16 kW, single and three-phase alongside stand-alone and split-units. These high-efficiency heat pumps are designed to operate at outside temperatures as low as –20°C, and also provide cooling in summer.  

Three versions are available. The Standard Heat Pump, as installed at the BASF House, the High Temperature Heat Pump (water output temperature of 65°C) and the Aquarea T-CAP (T-CAP for Total capacity) which is able to provide heating and hot water, whilst keeping the same nominal capacity, even at -15°C.

DDD Pharmaceuticals


VRF, Others


Background: Controlled temperature and monitoring is a necessity for any facility dealing with pharmaceutical storage and manufacturing processes. DDD Pharmaceuticals’ new site in Watford not only required controlled cooling for the warehouse, but also heating and cooling facilities for the offices at the plant.

Project Challenge:
 DDD Pharmaceuticals provides a complete service for manufacturing pharmaceutical products for clients in the health and beauty sectors. As with most pharmaceutical products, to maintain the safety, performance and efficiency of a product, the environment in which the item is manufactured, stored and distributed must be carefully maintained.  With around 15-tonnes of product on-site, a reliable solution was required.

For the manufacturing and storage phase at DDD, Panasonic’s new ECOi VRF range was specified as the ideal solution for the plant. Seven 16kW cooling only cassettes were installed in the pharmaceutical facility, with a further five to heat and cool in the offices, all piped from the same outdoor units.

Building Energy analysis: 
To meet the requests of DDD, TF Solutions opted to use Panasonic’s ECOi outdoor units with the indoor cassettes. The units are able to achieve an incredible COP performance of up to 4.04 when cooling and 4.56 whilst heating – giving excellent savings. The installation also makes the site compliant of the R22 regulations.

3rd Party Comments:
 “The requirement at DDD, although not unique, was somewhat complex” explains John Wakefield, designer of the HVAC installation at DDD. “Whilst constant and recordable conditions were required in the pharmaceutical storage and manufacturing facilities, we also needed a system that could provide adjustable heating and cooling to other onsite amenities. The Panasonic solution allowed for us to combine both these needs into one system, allowing for simultaneous operations whilst only requiring one set of outdoor units.”
