Integration of the heat pump in the heating system 8.15.2
8.15.2 Monovalent brine-to-water heat pumps
A heating circuit with overflow valve
Pre-configuration Setting
Fig. 8.32: Integration diagram for monovalent heat pump operation with one heating circuit and buffer tank connected in series
(a minimum buffer tank volume of 10 % of the minimum throughput must be ensured either by a buffer tank con-
nected in series or other suitable measures)
Operating mode
Mono-
valent
1st heating circuit Heating
2nd heating circuit No
Domestic hot water No
Swimming pool No
In systems which are not
equipped with controllers in the
individual rooms (TC), the over-
flow valve must be adjusted - in
combination with an unregulated
heating pump (M13) - so that the
minimum heating water flow rate
is ensured for all possible oper-
ating conditions.
The buffer tank, connected in se-
ries, increases the circulated vol-
ume and guarantees the mini-
mum runtimes required by the
compressor when only individual
rooms require heating (for exam-
ple, the bathroom).

If there is more than one heating
circuit, the generator and con-
sumer circuits must be hydrauli-
cally isolated.
The differential pressureless
manifold ensures the heating
water flow rate and must have
the same cross section as the
flow and return lines.
