5.4.4. Accessories
To be provided by the customer:
- Well pump with suitable output
- Motor protection switch for the well pump
- Water fi lter
- Water meter with shut-off valves
- Throttle valve
- Thermometer if required
To avoid corrosion and frost damage of the plate heat exchanger located in the heat pump, IDM-
Energiesysteme instruct to instal a safety heat exchanger for al ground water plants. Here the
heat pump groundwater circuit is decoupled via a safety heat exchanger by a brine circuit. This
means that any damage in the groundwater circuit or in the safety heat exchanger does not result
in any additional damage to the heat pump.
