Heating system connection
install the heat utilisation system
(wnA) in accordance with the
design documentation. For standard
heating systems integrate the heat
pump into the water side according
to standard circuits (see appendix).
Prior to connecting the heat pump,
check the heating system for leaks,
flush it thoroughly, then fill and
vent it thoroughly. Check the correct
connection of the heating flow and
return. Flexible pressure hoses are
recommended to reduce structure-
borne noise on the water side. the
required circulation pump and the
pipe cross-section can be determined
from the table below. Fit thermal
insulation in accordance with local
regulations. when using the compact
installation wPKi 5, use the following
circulation pumps: see table.
