Heating pipework
Use flexible pipes when integrating
heat pumps into the pipework. Also,
install an additional expansion vessel
because of the greater water volume
and the possible switching oFF of
the heat source. the heat pump is
protected in accordance with Din
4751 sheet 2. A buffer cylinder is not
required for systems large in mass
(underfloor heating system). if no
buffer cylinder is installed in the
system, fit the overflow valve between
the flow and return lines so that the
minimum heat pump flow rate is
maintained.
Structure-borne noise transfer
to prevent structure-borne noise
transfer to the pipework (possibly
also vibration transfers from central
heating circuit pumps), the installation
of hoses into the water pipework is
required. Use anti-vibration pipe clips.
Circulation pumps in the heat pump
circuit
when using a sbP 200 e or sbP 700 e
(buffer cylinder) and the heat pump
compact installation wPKi 5, size
the corresponding circulation pump
(cylinder primary pump) for the
heat pump in accordance with the
"Circulation pump" selection table.
Second heat source
For dual-mode systems, always
connect the heat pump into the return
of the second heat source (e.g. oil
boiler).
note: in accordance with the small
combustion system order (1st
bimschV) [or local regulations]
para 2: Dual-mode heating systems
para 15: the emissions test for the
second heat source is not required
with repeated supervision.
