7) Before acquisition of a water heater for space heating
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 require-
ments are available.
