Connecting hot water circulation (VVC)
VPB S/ VPBS S stainless steel and enamel have a con-
nection that allows hot water circulation, the HWC return
is connected to this (XL5).
Hot water circulation
A circulation pump can be controlled by a ground-source
heat pump or exhaust air heat pump, indoor module or
control module for circulation of the hot water. The cir-
culating water must have a temperature that prevents
bacterial growth and scalding, and national standards
must be met.
