They are energy efficient complete systems for heating and cooling which is both economic and environmentally sustainable.
This technology is available both for residential single/multi-family and industrial and commercial buildings.
The geothermal heat pump uses as a heat source the subsoil or ground water and allows a cost savings for the heating up to 80%.
You do not need to reside in a thermal area to enjoy the benefits of underground heat: from 10 m depth the soil temperature remains almost constant throughout the year, and around 100 meters the temperatures are around the 10-12 °C constituting a heat source for the optimum operation of the heat pump.
The air-water heat pump uses as a source of heat the outside air and allows a cost savings for the heating up to 50-60%.
It can produce hot water for heating or sanitary uses up to temperatures of 65 °C with only the compressor and work up to temperatures of -25 °C!
The exhaust air heat pump uses as a heat source stale air present in the house, allows a cost savings for the heating up to 50%.
