Heating

There are several ways to withdraw warmth from surrounding areas. Besides groundwater, also surface water, earth and air are usable heat sources. This animation shows the application of groundwater. The temperature of the pumped up water is about eleven degrees centigrade.

Having withdrawn the temperature from the groundwater, the system compresses the heat. This compression enhances the pressure and consequently increases the temperature.

A heat exchanger delivers the caused heat to the water, which in this case flows through floor pipes.

The used groundwater, now cooled down by a few degrees, flows back into the ground.
