Connection to heat source
The following can be used as heat source:
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.
Refer to the performance table to find the volume flow for the corresponding
heat pump.
The heat source connections (1¼“) feature an external pipe thread for flat-
sealing connections with union nut and insert.
The heat pump is equipped with a 12 l pressure expansion tank.
A circulation class A pump is installed at heat source side.
Optional equipment, energy class A pumps: The circulation pumps are offered
with internally coated housing (plastic).

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 oth-
er 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 groundwa-
ter systems.
