The system components for the
heat source and an unmixed
heating circuit are integrated in a
heat pump in compact design.
Domestic hot water preparation
is optional.
If required, the 2 kW immersion
heater integrated into the
compact air-to-water heat pump
can be replaced by a pipe
assembly.
Integration diagrams are clearly
marked through an 8-digit code
(e.g. 12211020).

The compact brine-to-water heat
pump can be directly connected
to the heating system due to the
integrated solid-borne sound
insulation.
The free compression of the
integrated brine circulating pump
is set for a maximum heat
exchanger depth of 80 m (DN
32). For a greater heat
exchanger depth the free
compression must be checked
and, if necessary, a DN 40 pipe
must be used.
NOTE
Heat pumps in compact
design can not be used for
bivalent systems.
