2.5 CONNECTION AND PIPEWORK
Pipes insulation
We suggest to insulate the cold water pipe to the water
heater and the hot water pipe from the water heater,
because they could freeze during the winter time.
The insulation of the tubes can be obtained by using
some covering in expanded elastomer.
Pipe section
The advisable pipe section is 1/2". However, if the
appliance is a long way from the point where hot water is
used, a 3/4" pipe section is suggested.
