Posted on February 22, 2023 How To Optimize Your Water Heater Temperature One of the essential appliances in any home is the water heater. Maintaining its health and efficiency is critical in caring for your plumbing system. These devices supply hot water for our showers, baths, dishwashing, and laundry. But did you know that your water heater temperature can affect your energy bill and the lifespan of your appliance? Maintaining an optimal temperature goes a long way toward reducing energy costs and improving your household’s safety. So here are some tips on optimizing your water heater temperature: A Safe And Efficient Temperature According to the U.S. Department of Energy, 120 degrees Fahrenheit is the recommended temperature for a water heater. Anything above 140 degrees Fahrenheit can cause burns or scalds. Moreover, higher temperatures can also increase the risk of mineral buildup in your water heater, leading to corrosion and decreased efficiency. If your water heater temperature is too high, you may spend more than necessary on your energy bill and replace your appliance sooner than expected. On the other hand, setting your water heater temperature too low can lead to bacteria growth and an inadequate hot water supply. Legionella bacteria, for example, grows best in temperatures between 77 and 113 degrees Fahrenheit. That’s why 120 degrees Fahrenheit is ideal for safety and efficiency. Adjust Temperature For Additional Needs In most cases, one hundred twenty degrees may be the optimal water heater temperature, but some households and properties can benefit from a different temperature range. For example, commercial kitchens may consider running water at 140 degrees Fahrenheit to help sanitize and clean dishes. If your dishwasher doesn’t preheat to 140 degrees, you may also want to set your water heater at that temperature to kill foodborne pathogens and bacteria more effectively. When in doubt, we recommend placing your water heater temperature at 120 degrees Fahrenheit, then increasing it by ten-degree increments if you need to fulfill additional needs. Generally, a temperature range between 120 and 130 degrees Fahrenheit provides enough hot water for your daily needs while minimizing the risk of burns, scalds, and bacteria growth. Optimize Your Water Heater Temperature: Step By Step To optimize your water heater temperature, follow these tips: First, check the temperature setting: You can find the temperature setting on your water heater’s thermostat. Adjust it between 120 and 140 degrees Fahrenheit based on the above information. Test the water temperature: You can use a thermometer to test the temperature of the hot water coming out of your faucet. Adjust the temperature setting accordingly if it’s too hot or too cold. Consider your household’s hot water needs: If you have a large family, you may need to set your water heater temperature higher to make your hot water last longer. However, if you live alone or with a small family, you can set it lower to save energy and reduce the risk of burns. Install a mixing valve: A mixing valve can help regulate the water temperature and prevent scalds. It mixes hot and cold water to provide a consistent temperature.
