Water Heater Thermostat Temperature: What Should I Set Mine At?
If we asked you for ideas on how to save energy at home, one of the first that might come to mind is lowering the thermostat setting on your home heating system. But there’s another thermostat in your home that can also help you save money: your water heating thermostat.
When most water heater manufacturers set their thermostats, they use a default setting of 140 degrees – a temperature that is hot enough to scald, and higher than most people need. According to the U.S. Department of Energy, a 120°F setting is more than enough to slow mineral buildup and corrosion in your water heater and pipes while keeping your water supply safe to use. By dropping the thermostat on your water heater by 20 degrees, you’ll burn less heating oil, saving money in the process.
While most people can get by setting their thermostat to 120°, certain homeowners should keep to 140°. For example, if in the house has a suppressed immune system, a 140-degree setting is preferred to prevent water-borne health risks. Also, if your dishwasher doesn’t pre-heat water, you might want to maintain the higher temperature.
