The ground, by connection to a horizontal geothermal absorber (e.g.
PE-pipe20x2) or a vertical geothermal absorber (geothermal probes).

The groundwater, by connection to a well system, using an accessories
kit available from WATERKOTTE to monitor the flow at heat source side
and separation heat exchanger (heat source side).

The layout of the heat source system must be according to the
WATERKOTTE dimensioning information. .

The heat pump also includes the following:

One air separator

One safety fitting (air diverter / filling pressure gauge / safety valve)

To prevent formation of condensation, the heat source lines inside the
house must have diffusion tight insulation.

In case of water glycol systems, it is not permitted to use steel pipes
and other steel components in the water circuit. Use stainless steel,
copper, brass or plastic - such as PE - for instance.

Steel pipes and other steel components should also be avoided in
groundwater systems.
