1st heating circuit Heating
2nd heating circuit No
Domestic hot water No
Swimming pool No
The heating water flow rate must
be ensured using an overflow
valve that must be set by the
technician during commissioning
(seeChapt. 8.3 on page 95)
The use of the compact manifold
KPV 25 with overflow valve is
recommended for heating sys-
tems with panel heating and a
heating water flow rate up to
max. 1.3m
3
/h.
If electric heating is installed in
the buffer tank, it should be pro-
tected as a heat generator ac-
cording to DIN EN 12828.

The heating water flow rate must
be ensured using a differential
pressureless manifold (see
Chapt. 8.3.4 on page 96)
The use of the compact manifold
KPV 25 with EB KPV extension
module is recommended for
heat pumps with a heating water
flow rate of up to max. 2m
3
/h.
A method of manual drainage
must be provided for heat
pumps which are exposed to
frost (see Chapt. 8.2 on page
94).
