How does it work?

The outdoor unit draws energy from the air to deliver heating, cooling and hot water. It taps up to 75 % ambient energy, topped up by electricity. The air-to-water heat pump transfers this energy to water through a compressor and refrigerant, then sends the heated water around your home as required.

Low-temperature technology

Perfect for newer builds, this pump is engineered for under-floor heating and low-temperature convectors, ensuring comfort on par with traditional radiators.

Refrigerant connection

Made up of an air-drawing outdoor unit and an indoor control unit, the split heat pump uses refrigerant piping to cut heat losses while transferring energy inside.
