2. Design
The picture below shows the fundamental construction of the heat pump.
The energy in the bore hole (bedrock) or ground is drawn up by the cooling
system. The compressor then increases the temperature to a usable level.
Afterwards it releases the energy for the heating circuit and DHW.
Tap water connections
The property’s tap water
connections are connected
here.
Radiator connections
The property’s heating
system is connected here.
DHW heat exchanger
The heat pump is equipped with a
stainless heat exchanger.
Direct heating of hot water
minimises the risk of legionella
bacteria.
Flow heater
There is an immersion heater for
additional heating here.
3-way valve
Flow conditioner.
Terminal block for sensors
The sensor terminal block is
connected internally. Outdoor
sensors, room sensors and
other sensors are connected
easily here.
