Heat pumps

Using free environmental heat with a heat pump

Heat pumps are a great alternative to oil or gas heatings especially when it comes to new buildings. A geothermal heat pump system scores. A geothermal heat pump system  can easily be installed and works very efficiently

KWB heat pumps can be used for water heating, to cool down and work as central heatings. KWB offers air-water-heat pumps, heat pumps for water heating and the appropriate storage technology.

Our heat pumps have a high coefficient of performance and work really quiet. Because of the high COP a lot of energy can be saved.

Our heat pumps are delivered ready to plug-in and can therefore easily be installed. KWB only collaborates with certified companies. You will profit from the highest installation quality. We guarantee for speed of action, professionality and favorability when it comes to the exchange of your heating.

When to use a heat pump?

Air heat pumps are mainly utilized as central heatings, when there is a low heat demand. They are mostly deployed in new or well isolated buildings. Heat pumps work most efficiently when used in systems that have a low flow temperature (e.g. underfloor heatings and panel heatings)

How does a heat pump function?

[Translate to English:] Die Funktionsweise einer Wärmepumpe

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.
