WATER TEMPERATURE ADJUSTMENT
It is recommended that the thermostat be set for the lowest possible temperature that satisfies
your needs. This will also provide you with the lowest energy consumption and cost.
Check the water temperature at a hot water faucet soon after the tank thermostat has
satisfied, and the circulator and the boiler have turned off. Adjust as needed.
Lowering the thermostat setting will not have an immediate effect on the water temperature
because the stored water will have to be used and the thermostat must go through the cycle of
heating cold water and satisfying at the new, lower temperature. Additional temperature
checks should follow the completion of a heating cycle. Further adjustments may be required
after you have used the water heater.
The table below details the approximate
relationship of water temperature and time
with regard to scald injury and may be used as
a guide in determining the safest water
temperature for your applications.
The scald label shown to the right can be
found on all Heat-‐Flo Indirect Water Heaters
and Storage tanks. Take note and use caution
when adjusting the temperature settings with
your water system. Be sure to always feel the
water before bathing or showering, especially
when drawing a bath for an infant or elder.
