Since Callahan’s Gas & Appliance has been installing water heaters in Centreville and the surrounding area for decades, we commonly get asked what temperature water heaters should be set at. While this task is not as technical as many appliance repairs, maintaining the right water temperature for your household can save you money and keep you safe. In today’s appliance repair blog post, we will discuss how to determine the right water heater temperature setting for your home and how to set that temperature.

Common Temperature Settings

To determine the right temperature for your water heater, it will first be helpful to understand common temperature settings used in water heaters. Most manufacturers use 140 degrees Fahrenheit as the default water temperature setting. Depending on the water heater you buy, possible temperature settings can range from 115 degrees Fahrenheit to 160 degrees Fahrenheit.

Most guides for setting water heater temperatures focus on temperature increments between 120 and 140 degrees Fahrenheit. When setting water heater temperatures, people typically have four things in mind:

  • Preventing burns
  • Preventing bacteria and germ buildup
  • Saving money on electric bills
  • Meeting household demand for hot water

Temperature settings closer to 120 degrees Fahrenheit are great for burn prevention, saving money on electricity, and meeting the needs of households that do not use a large amount of water. In contrast, temperature settings nearer to 140 degrees Fahrenheit are better for killing bacteria and germs, as well as households with a greater hot water demand.

Analyze the Needs of Your Household

If you want to find the perfect water heater temperature for your home, then you need to begin by analyzing the various needs of your household. Do children live in your house? Are your pipes insulated? Do you have a dishwasher that heats water to 140 degrees Fahrenheit?

These are just a few of the questions that should be asked prior to setting your water heater temperature. Depending on the answers above, you can determine the right temperature setting for your home. The key is to think of the needs and desires of the people that will be using hot water in your house.

Whatever your house needs specifically, it is crucial to keep burn and bacteria prevention, electricity spending, and household demand in mind. Water heater temperatures at 140 degrees Fahrenheit or higher can quickly burn children and significantly drive up your electric bill, while lower water temperatures may prove harmful to people with auto-immune disorders or respiratory issues. Since appliances are designed to make our lives easier, it is best to set them up in a way that meets your unique needs.

Changing the Temperature Settings

Typically, changing the temperature settings on a water heater is a simple appliance repair to perform. Many times, the water heater features a dial that can simply be turned to adjust the temperature. In other cases, changing the temperature on your water heater might involve first cutting power to the appliance, removing some screws, and then relighting the pilot light after the temperature is changed.

In some cases, the temperatures for your water heater may not be listed on the heater itself. In this situation, remember that you can always check any information provided by the manufacturer or ask a member of the Callahan’s team to find out what temperature settings are available to you. Our team of appliance-repair experts is happy to help you with your water heater and install a new water heater when necessary.
