How a heat pump works

The outdoor unit harvests thermal energy from the air to supply heating, cooling and domestic hot water. Up to 75 % of the energy is drawn from the air, the remainder from electricity. The air-to-water pump uses a compressor and refrigerant to move this energy into water, which is then heated and circulated throughout your home.

Low-temperature technology

Ideal for new builds, these pumps run with underfloor heating or low-temperature convectors, delivering comfort matching traditional radiators while maximizing energy efficiency.

Refrigerant link

Split systems pair an outdoor air-capture unit with an indoor control unit. Refrigerant minimizes heat losses while transferring warmth into the dwelling.
