2 Functional principle of an heat pump
The heat pump is used to produce thermal energy for space heating and domes-
tic water heating if required. The medium used as heat source (WQ) is the ground.
It is also possible to cool a building.
To utilise ground as thermal energy, for domestic water heating and cooling in
your home, you need the following:

a heat source (borehole with geothermal energy probes or groundwater ex-
traction / discharge)

heating system Ai1 QE

domestic hot water tank

2.1 Description of operation Basic Line Ai1 Geo
The WATERKOTTE heating central Basic Line Ai1 Geo uses a heat pump as heat
generator. At the heat source side the medium is cooled down in the vaporizer
about 3 to 4K with the help of this device. The hereby won energy is made usable
for heating purposes by transport through the cooling circle up to a higher tem-
perature level.
Heating energy is given to the medium about the liquefier at the heating side, so a
temperature rise about 5K is reached.
On this way building heating and domestic water heating can be done.
The configuration of the heat source system must be planned in accordance with
the technical information of WATERKOTTE GmbH heat source installation instruc-
tions.
