8.12.2 Monovalent brine-to-water heat pump
A heating circuit with overflow valve
Preconfiguration Setting
Fig. 8.21: 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
connected in series or other suitable measures see Chap. 8.5 on p. 180)

In systems which are not
equipped with controllers in the
individual rooms (TC), the
overflow 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 operating conditions.
The buffer tank connected in
series increases the circulated
volume and guarantees the
minimum runtimes required by
the compressor when only
individual rooms require heating
(for example, the bathroom).

If there is more than one heating
circuit, the generator and
consumer circuits must be
hydraulically isolated.
The differential pressureless
manifold ensures the heating
water flow and must have the
same cross section as the flow
and return lines.
