6) If the incoming water line to the heater is equipped
with a check valve, water meter, or pressure-reduc-
ing valve, an expansion tank must be installed in
the system. This will prevent weeping from the
water heater relief valve and premature failure of
the heater due to expansion of the water during the
heating cycle.
7) Before acquisition of a water heater for space heat-
ing application, it is necessary to have the area of
intended use sized by a qualified technician.This
will ensure that an adequate water heating
capacity will be available for both heating and
potable water supply, and that the application will
meet all local codes and public utility requirements.
Note:
It is good practice to oversize the water heater,
to ensure that all of the potential hot water
requirements are available.
