Water-to-water heat pumps use heat energy from groundwater. Depending on the heating capacity, we have to provide the correct amount of flow of well water through them. Water is used from drilled wells by using built-in well pumps. Water flows through heat exchanger and losses some amount of heat energy (it cools down). Heat energy is transported through cooling system to the other exchanger, through which water from the heating system passes. Transported heat energy is delivered to the water. Through this process, water from the heating system receives a certain amount of heat energy (it heats).

Electric power is used only for ‘transport’ of heat energy in the opposite direction of natural movement- heat is naturally spread from warmer to colder object. Heat pump provides energy transfer from colder well water to warmer water in the heating system. With 1kW of electricity, 4-6kW of heat energy flows into the heating system. This relation is described with COP factor.

The advantage of this system is that regardless of the outdoor temperature, the pump capacity as well as the coefficient of performance remain constant.

With these heat pumps the lowest consumption of power can be achieved, however they need a space for well drilling.

Braun company offers water-to-water heat pumps with DC inverter compressor, as well as classical On/Off heat pumps.

Table below shows our models of heat pumps, their characteristics, as well as prices:
