Help with Planning and Installation 10.3
10.3 Minimum Requirements for Domestic Hot Water Cylinder / Circulating
Pump
Air-to-water heat pump for indoor installation
Air-to-water heat pump for outdoor installation
Brine-to-water heat pump for indoor installation
Water-to-water heat pump for indoor installation
(On the basis of the integration set-ups recommended in this
manual and standard boundary conditions)
The table shows which domestic hot water circulating pumps and
cylinders should be allocated to each type of heat pump in order
to obtain a hot water temperature of approx. 45 °C in operation
with 1 compressor (maximum temperature of the heat source:
Air: 25 °C, brine: 10 °C, water 10 °C).
The maximum hot water temperature which can be attained with
heat-pump-only operation is dependent on:
 The heat output of the heat pump
 The heat exchanger surface area in the cylinder
 The volume flow in relation to the pressure drop and the
capacity of the circulating pump.
NOTE
Higher temperatures can be reached by implementing larger heat
exchanger areas in the cylinder, by increasing the volume flow or by
targeted reheating using a heating element (see also Chap. 6.1.3 on p.
149).
