DANGER
The temperature at which injury occurs varies with the person's age and time of exposure.
Water temperature over 125°F/52°C can cause severe burns instantly or death from scalding.
The slower response time of disabled persons increases the hazards to them. Never allow small children
to use a hot water tap, or to draw their own bath water. Never leave a child or disabled person unattend-
ed in a bathtub or shower.
The appliance should be located in an area where the general public does not have access to the
temperature control.
Lower water temperatures should be used to avoid the risk of scalding. It is further recommended, in all
cases, that the domestic water temperature be set for the lowest temperature which satisfies the user’s
hot water needs. This will also provide the most energy efficient operation of the water heater and
minimize scale formation in the heat exchanger, thus prolonging the life of the unit.
Setting the domestic hot water temperature at 120°F/49°C will reduce the risk of scalds. Some
jurisdictions require settings at specific lower temperatures. The table below shows the approximate
time-to-burn relationship for normal adult skin.
Hot water temperatures required for automatic dishwasher and laundry use can cause scalds and burns
resulting in serious personal injury and/or death.
Temperature
Setting
Over 170°F/77°C
160°F/71°C
150°F/66°C
140°F/60°C
130°F/54°C
120°F/49°C or less
Time to Produce 2nd, 3rd
Degree Burns on Adult Skin
Nearly instantaneous
About 1/2 second
About 1-1/2 seconds
Less than 5 seconds
About 30 seconds
More than 5 minutes
To protect against injury, installing a tempering valve in the domestic hot water supply is
recommended. This valve will reduce point of discharge temperature by mixing cold and hot
water in branch supply lines. Such valves are available from the local plumbing supplier.
