Aquarea Loop: Radiator retrofit solution for centralised heating with integrated cooling
A decentralised water-to-air heat pump using natural refrigerant R290, designed to replace radiators in centralised heating systems.
Aquarea Loop delivers heating and cooling for buildings with a central water loop 20~30°C. It is designed to integrate with existing pipework and reduce the thermal distribution losses.
Low thermal losses
Simultaneous heating and cooling
Use of existing pipework for renovations*
Unit-level energy metering
* Based on the low flow rate requirement – must be checked on each project.
Seamless integration with existing systems
The Aquarea Loop is the perfect replacement for existing radiators, ensuring optimum temperatures all year round.
1. Centralised Aquarea Heat Pump (first stage of generation) replacing a high temperature traditional heat source
2. Loop water temperature 20~30°C. The existing pipework may be reused
3. Aquarea Loop heat pump (second stage of generation) replacing conventional radiators
Water Loop: 20 ~ 30 °C
Upgrade existing centralised heating installation and add cooling
Allows to upgrade the existing heating installation to add cooling without major renovations.
Simultaneous heating and cooling for mixed-use buildings or zones with different temperature needs is possible.
Retrofit without disruption
Replace old radiators while reusing existing pipework, minimising installation costs and downtime.
* Based on the low flow rate requirement – must be checked on each project.
Individual control with unit-level energy metering
Each unit manages its own heating and cooling.
The unit-level energy metering ensures accurate billing for residential or commercial projects.
High seasonal efficiency and low thermal losses
Water loop circulates at 20~30°C, contributing to a better system performance. The Aquarea Loop adjusts the water temperature to optimal levels, ensuring each room is properly heated or cooled.
This design can help reduce heat distribution losses and improve overall system efficiency.
Ideal applications
Social housing / Multi-family buildings / Hotels / Schools / Offices
