How it works

Air-to-water heat pumps are based on the principle of obtaining heat from the surrounding air, the temperature of which can be many degrees Celsius below 
zero. The heat taken from the surroundings is transferred to the heating water of the heating object by means of a heat pump, or used for the preparation of hot water. The system achieves a seasonal efficiency of up to 4.5 times higher than a conventional electric boiler and thus brings significant energy savings.

Among the biggest advantages of air-to-water pumps are relatively low investment costs, fast and easy installation and easy availability of the primary energy source: air is all around us.

Air-to-water heat pumps are suitable not only for heating and year-round heating of hot water or swimming pools, but also for cooling the building in the summer months thanks to the possibility of reverse operation.
