Water Temperature Safety

Safety and energy conservation are factors to be considered when selecting the water temperature setting of the water heater's thermostat. Water temperatures above 125°F can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below.

The chart shown below may be used as a guide in determining the proper water temperature for your home to prevent burns.

Time/Temperature Relationship in Scalds

DANGER: Households with small children, any disabled person, or elderly persons may require a 120°F or lower thermostat setting to prevent contact with overly "HOT" water. The temperature of the water in the heater is regulated by the electronic control on the front of the water heater.

Notice: Mixing valves are recommended for reducing point of use water temperature by mixing hot and cold water in branch water lines. It is recommended that a mixing valve complying with the Standard for Temperature Actuated Mixing Valves for Hot Water Distribution Systems be installed.
