Information on drinking water filter
According to DIN 1988-2, a drinking
water filter should be installed in systems
with metal pipework. We also recom-
mend the installation of a drinking water
filter when using plastic pipes, according
to DIN 1988, to prevent contaminants
entering the DHW system.
Safety valve
Protect the DHW cylinder with a safety
valve against unduly high pressure.
