What Temperature Should a Hot Water Heater Be Set?

27th May 2022

Ever dealt with water in your home that was too hot or too cold? This is typically due to your water heater being set at an incorrect temperature. Your water heater is an essential part of your home, so it's important to know what the ideal temperature setting is and what risks come with setting the temperature too high or too low.

It is recommended by most water heater manufacturers and plumbers that you set your water heater to 120 degrees Fahrenheit. This temperature is ideal for most homes because it provides a good balance between efficiency and safety. But what happens when you set the temperature too high or too low?  NuvoH2O shares the risks that come with each below.

Scalding Accidents

Scalding accidents can occur when the water temperature is set too high and someone comes into contact with the hot water. These accidents can cause serious burns and require immediate medical attention. To avoid scalding accidents, always test the water temperature before using it, and never set the water heater above the recommended temperature.

Higher Bills

When the temperature of your water heater is set too high, your energy bills will increase. That's because the water heater has to work harder to maintain the higher temperature, which uses more energy. If you're looking to save money on your energy bills, setting the water heater to a lower temperature is one way to save money. Just be aware of the risks that come with setting the temperature too low (coming up next).

Susceptible to Diseases

If the water temperature is set too low, bacteria can start to grow in the water heater. This is especially true if the water heater isn't being used frequently. While most bacteria are harmless, some can cause serious diseases. To avoid this, it's important to clean your water heater regularly and set the temperature to at least 120 degrees Fahrenheit.

Reduced Lifespan

Hot water heaters typically have a lifespan of about eight to twelve years. But if the temperature is set too high, the lifespan will be reduced. That's because the higher temperatures put additional stress on the tank, which can lead to premature corrosion. So, if you want your water heater to last as long as possible, be sure that it is set at the recommended temperatures.

Now that you know what temperature to set your water heater and the risks that come with setting it too high or low, you can help extend the lifespan of your water heater and keep your home safe.
