What Temperature Should I Set My Water Heater?

Many homeowners have no idea of their water heater temperature – or how to set it. Having a better understanding of the appropriate temperature for your hot water needs can help lower monthly energy costs, prevent scalding water from causing injury and prevent bacteria from growing in the stagnant water sitting in the water tank.

According to the EPA, most homeowners should set their water heaters to 120 degrees. You can determine the current temperature by looking for the temperature gauge on the heater or by running the kitchen faucet for at least 5 minutes (until the water gets hot) and taking the water temperature using a thermometer.

However, if you live in a home with multiple occupants, increasing the water temperature to 140 degrees allows you and your family to have plenty of hot water for showering, dishwashing, clothes washing, etc.

Families with small children and elderly members; or those who live alone may want to set the water temperature to 120 degrees to prevent injury or to lower energy costs.

Water temperatures above 140 degrees can cause young children to receive third-degree burns within seconds, so parents should beware of setting the temperature of water heaters too high.

To reduce monthly energy costs, you can lower the temperature by 10 percent and save between 3 and 5 percent on monthly bills. Keep in mind that temperatures below 120 degrees can lead to bacteria growth in the water heater tank.
