Domestic water heating
If the unit is to be used for domestic water heating, a
3-way changeover valve must be installed. This is not
included with the unit and must be ordered separately.
IMPORTANT
Only use the manufacturer’s original accessories.
Domestic water heating with the heat pump requires an
additional heating water circuit (parallel) to the heating
circuit. When connecting, make sure that the domestic
hot water charge is not fed through a buffer tank in the
heating circuit.

Domestic hot water tank
If the heat pump is to be used for domestic water heat-
ing, you must integrate special domestic hot water tanks
in the heat pump system. Choose a storage volume so
that the required quantity of domestic hot water is avail-
able even during a power failure.
NOTE:
The heat exchanger surface of the domestic hot
water tank must be dimensioned so that the
heating output of the heat pump is transferred
with minimum spread.
You can choose a domestic hot water tank from our
product range. They are optimally matched to your heat
pump.
NOTE:
Integrate the domestic hot water tank in the
heat pump system as shown in the hydraulic dia-
gram for your system.
