Integration of the heat pump in the heating system 8.4.1
8.4.1 Compact manifold KPV 25
The compact manifold functions like an interface between the
heat pump, the heating distribution system, the buffer tank and,
in some cases, even the domestic hot water cylinder.
A compact system is used to simplify the installation process, so
that a lot of different components do not have to be installed indi-
vidually.
NOTE
The use of the compact manifold KPV 25 with overflow valve is recom-
mended for heating systems with panel heating and a heating water flow
rate up to max. 1.3 m

/h.
