Operating principle of heat pumps Heat pumps operate on the principle of a refrigerator: the same technology, only with the opposite effect. The refrigerator extracts heat from foods, which is released into the room through fins on the back. The heat pump extracts heat from our environment: air, earth or ground water. The extracted heat is conditioned in the unit and supplied to the heating water. Even when it is extremely cold outside, the heat pump draws enough heat to heat a house.
Cooling function The cooling function is available only for heat pumps with the model designator K. It is not possible to retrofit heat pumps for cooling without this designator. For the model designator, please refer to the purchase documents. It is also on the rating plate attached to the outside of the unit.
