The Aerona R290 features a streamlined design with a modern aesthetic, making it a practical and visually appealing choice for a range of residential applications. By leveraging the thermodynamic properties of R290, this system ensures exceptional performance while aligning with stricter environmental regulations and sustainability goals.
Specifically designed for high-efficiency space heating and domestic hot water production, the Aerona R290 integrates advanced controls, including the Aerona Smart Controller, enabling seamless remote monitoring and management. This heat pump is an ideal solution for professionals seeking to deliver sustainable, cutting-edge heating systems to meet the demands of eco-conscious homeowners.
Features & benefits
- Single phase heating outputs including 4kW, 6.5kW and 9kW, each rated at -5°C air temperature and 55°C water flow temperature
- Featuring sound-reducing features, such as acoustic cotton sound insulation in the casing and twin eccentric cam levers with balancing weights, each heat pump operates with ultra-low sound levels and is Quiet Mark accredited
- Designed for installation with the Aerona Smart Controller, the Aerona R290 can be remotely managed and monitored to assist heat pump installers with off-site diagnostic support as well as facilitating weather and load compensation, heating curve adjustments and set-up support
- Features built-in PWM circulating pump, DC twin rotary compressor, low- and high-pressure protection controls, discharge temperature protection controls and factory-fitted automatic air vent and 3-bar pressure relieve valve
- Uses electronic expansion valve to precisely control the flow of R290 refrigerant into the evaporator as well as a 4-way valve to divert the refrigerant flow for the defrost operation
- Incorporates R290 refrigerant safety features including a refrigerant leak sensor and independent ventilation channels allowing for fresh air intake
- Units have an anti-freeze protection heater on the plate heat exchanger and heated base tray. Mechanical anti-freeze valves can be used to protect the external system pipework, as glycol antifreeze cannot be used
- Multiple condensate drain holes in the base tray and overflow holes facilitate the clear removal of condensate from the heat pumps

What is Refrigerant R290?
Refrigerant R290, which is better known as Propane, is a natural refrigerant that is commonly used in air conditioning systems and refrigeration and is being increasingly used in air source heat pump technology. This is because refrigerant R290 is non-toxic, is odourless and has excellent thermodynamic properties which aid the incredibly efficient operation of a heat pump.
