Cold and hot water

Connecting cold and hot water
There must be a mixing valve if the temperature can ex-
ceed 60 °C.
Connecting hot water circulation
VPB/VPBS R and E have a connection that allows hot
water circulation.
To reduce the risk of bacterial growth in systems with
hot water circulation, the temperature of the circulating
water should not fall below 50 °C. There should not be
any non-circulatory hot water pipes. Adjust the hot water
system so that the temperature does not fall below 50
°C at the ends of the system.
