Geothermal energy probe

Is inserted 30 to 100 m into the ground through a columnar shaft. Geothermal energy is produced by connecting the probe with ground through special heat-conducting substances.

Geothermal probe

Part of the heat pump that is inserted into the ground to withdraw thermal energy. Consists of pipelines through which a working fluid flows

Global Warming Potential (GWP)

Global Warming Potential indicates how climate-damaging a chemical substance is compared to carbon dioxide (CO2)

Gravity brake

Prevents unwanted circulation of the water in a circuit due to temperature changes when it is not needed. 

Ground collector

Part of the heat pump that is inserted into the ground to withdraw thermal energy from it. Consists of pipelines through which a working fluid flows

Ground heat exchanger

Can use relatively constant geothermal energy to heat up cool outside air before it is directed into the living space. If the outside air is already hot, the effect can also be reversed. This results in a cooling effect 

Groundwater

Accumulation of water below the ground, mostly due to precipitation. The relatively constant temperature makes it suitable as heat source for heat pumps
