How does a heat pump work?

The outdoor unit captures thermal energy from the air to deliver heating, cooling and domestic hot water. Up to 75% of the energy comes from the air, the rest being supplied by electricity. The air-to-water heat pump uses a compressor and refrigerant to transfer this energy to water, which is then heated and distributed throughout your home as needed.

Low-temperature heat pump

Designed for new builds, these units are optimized for underfloor heating and heat-pump convectors. Operating at low temperature, they deliver comfort comparable to traditional radiators while achieving higher energy efficiency.

Refrigerant connection

Split heat pumps consist of an outdoor unit that captures air and an indoor unit acting as the control hub. The refrigerant link minimizes thermal losses when transferring heat inside.
