2. Appliance description
The groundwater station is an assembly with a stainless steel
plate heat exchanger in a duplex casing made from thermally
insulating plastic.
The purpose of the groundwater station is to use groundwater
as a heat source and it can be connected to ground source
heat pumps.
The connections for the air vent valve and drain & fill valve are
the same. The groundwater station can therefore be rotated
180° and installed on the left or right of the ground source heat
pump, depending on the location.
The groundwater station comprises several components,
which are described in the following diagrams.
