Heating cycle
WSP compact heat pump models are ideal for use in new or in existing buildings, where the heat pump is
the sole heat generator.
The highly efficient primary pump inside the unit is used as the heating cycle pump. The combination buffer
tank consists of an enamelled 300 l hot water tank [C1] and a 100 l vapour diffusion-tight buffer tank for
increasing the volume [C2] which is integrated into the return flow of the heating system. The buffer tank can
also serve as a hydraulic compensator if the pressure losses of the heating system are too high (see “Tech-
nical Data”).
n
The heating cycles connected must be hydraulically balanced.
n
The pressure drop between heat pump and storage tank must not exceed 40 kPa.
n
A minimum water flow volume of 20 l/KW must be assured.
n
The pipe cross sections of the lines from the heat pump to the storage tank may not be reduced.
n
The min. water volume with active cooling must be observed.
