When it comes to setting the temperature for your home’s water heater, there are several factors to consider other than personal preference. Manufacturers’ requirements, appliance requirements, and at-risk groups are important factors to be considered. Some manufacturers require a thermostat set at 140°F, yet most households require only a setting of the thermostat at 120°F. Some appliances, usually a dishwasher without a booster heater may require a setting between 130°F and 140°F for optimum heating. Water temperatures above 130°F can pose a safety hazard for certain at-risk groups such as small children and disabled or elderly residents.
Recommended Water Temperature
According to the U.S. Department of Energy, a temperature of 120°F at the tap is adequate for most household chores with a minimal danger of scalding and maximal energy efficiency. However, that is the temperature at the tap, not in the tank. Tank temperatures should be no less than 130°F to prevent bacterial growth. It is always good to test your water temperature at the tap. This can be done with a simple cooking thermometer and a deep glass. Just wait for the water to run fully hot and then fill the glass and measure.
