Brine/water heat pumps
Brine/water heat pump draws its energy from the ground.
Surface collectors or geothermal probes of up to 100 metres deep can be used depending on the space available and the nature of the ground. Deep drilling is necessary for the installation of a geothermal probe. In both cases, frost protected brine is used as a heat transfer medium. An appropriately equipped heat pump can also be used in summer for cooling rooms.
