How does a heat pump function?

The functional principle of a heat pump is easily explained: The pump withdraws heat from its environment (environmental energy) and gives it off tot he filament circuit of the building connected. In ordert o do so the pump needs electricity (driving energy).

The ambient air (1) is giving off part of its caloric energy to a liquid cryogen (2). In that way the cryogen vaporizes. After that it gets densified with the help of a compressor and driving energy. (3). In that way the cryogen warms up.

In the condesor the cryogen gives off part of its caloric energy  to the heating circuit (5) and fluidises again (4). Because of an expansion valve the cryogen depressurizes (6). After that the process starts all over again.

The coefficient of performance is an important technical information when it comes to heat pumps. COP describes the proportion of the thermal output that has been generated to the electric power. If the coefficient of performance of a heat pump is for example 4, the heat pump produces 4 kWh heat by consuming only 1 kWh electricity. 

KWB heat pumps are government-funded.

That’s why KWB heat pumps are your best choice!
