Depending on the location, groundwater can be extracted through wells and can be directly led into a heat pump evaporator. It must, however, also be led back into the underground and thus, besides the wells, re-absorption wells must be drilled.

Groundwater heating pumps can utilise fairly high heat source temperatures and thus avoid underground heat exchanger losses. This is reflected positively in the annual work output. In the case of larger applications these systems are thus economically more feasible than geothermal probes. However, their operation in the groundwater depths is not always easy, since a constant flow of water and a certain quality of water must be given.
