Answer: the water heat pump draws heat from a water source (groundwater, stream) through drilling.
While the geothermal heat pump draws heat from the ground as such, the water heat pump, also called a hydrothermal heat pump, draws heat from the water, this water being able to come from a ground water table or from a stream located near you. Vertical drilling allows you to reach the water table and draw the water at a high temperature, then bring it to the surface and use it directly to supply your radiators, for example. To avoid drying up the source, it is recommended to do a double borehole, the second allowing the water to be discharged in the same place once it has cooled. The difficulty of the water CAP lies in the administrative procedures required, and the very high cost of single or double drilling. It is also essential that the water table is not too deep, otherwise the energy required to raise the water would negate the value of the operation.
