Wondering What Temperature To Set Your Water Heater At? Use This Temperature Setting!


When it comes to your water heater, finding the right temperature setting can significantly impact your comfort and your home’s energy efficiency. Most homeowners don’t know the best temperature setting for their water heaters. Luckily, we’re here to provide recommendations to ensure your water heater operates optimally.

In this blog, we’ll answer some of the most common questions homeowners have when setting and adjusting their water heater temperature.

What Is the Recommended Water Heater Temperature?

Finding the right water heater temperature setting involves balancing safety, energy efficiency, and functionality. Most experts recommend setting your water heater thermostat to 120 degrees Fahrenheit. This temperature provides comfortably warm water for various household activities, including showering, washing dishes, and doing laundry.

However, there are exceptions. A slightly higher temperature — around 140 degrees Fahrenheit — might be more suitable for households with immunocompromised individuals. This elevated temperature helps prevent the growth of harmful bacteria in the water supply, ensuring a safer environment.

How Do I Figure Out My Water Heater Temperature Setting?

Determining your current water heater temperature setting is a straightforward process. All you have to do is locate the thermostat on your water heater, which is usually a dial with temperature markers.

If you suspect that the thermostat is incorrect, you can use a thermometer to check the temperature of the water coming out of a nearby faucet. Once you know the actual temperature of the water, you can adjust your thermostat accordingly.

How Will Adjusting My Water Heater Temperature Affect My Home?

Changing your water heater temperature setting will affect your household in a few noticeable ways. Lowering the temperature to 120 degrees Fahrenheit can lower your monthly energy costs. The reduced temperature means your water heater doesn’t need to work as hard to maintain the desired warmth, making it more efficient.

Lower water temperatures can also slow down the corrosion process within your water heater, which may extend its life span. However, it’s important to remember that excessively low temperatures could encourage bacterial growth, which may be unsafe for those with underlying health issues.

On the other hand, if you choose to set your water heater temperature higher — around 140 degrees Fahrenheit — you’ll effectively eliminate many harmful bacteria. However, there’s a trade-off: the risk of scalding increases, especially for children and elderly individuals. You may also notice higher energy costs.

How Do I Adjust My Water Heater Temperature Setting?

Adjusting your water heater temperature setting can be a DIY task, but it requires caution and attention to detail. Here’s how it’s done:

  • Turn off the electricity or gas supply to your water heater.
  • Follow the manufacturer’s instructions to access the thermostat dial.
  • Gradually adjust the dial to your desired temperature setting.
  • Once the adjustment is made, turn the power back on and wait for the water heater to reach the new temperature.

If you’re uncomfortable performing this task yourself, don’t hesitate to hire an experienced plumber. Professionals can ensure the adjustment is made safely and accurately, preventing potential issues.
