For lots of people, there’s nothing better than a hot shower to start the day. Even though that may just be a fantastic way to wake up and start the day, experts say you can set your water too hot.

Setting your water heater to a temperature that’s above the recommended degree can waste electricity and cost you money. It also can pose a safety concern for members of your family. But, if you set your water heater temperature too low, it can enable growth of potentially harmful bacteria and not supply enough hot water for your household.

So, what temperature is the right one for your water heater? In this article, we’ll identify the most effective temperature to use, when there could be reason to set it a little higher and how hot is too hot for your own water heater.

What Temperature for my Water Heater Is the Most Energy Efficient?

Although many companies suggest setting the water temperature at 140 degrees, a more efficient temperature for a water heater is 120 degrees Fahrenheit. Experts say 120 degrees provides the right balance between safety and energy use.

The U.S. Department of Energy reports that setting a home water heater temperature at 120 degrees could save roughly 22 percent on energy costs. Energy waste is a frequent challenge for water heaters because traditional tank models always heat a tank of water in case it is demanded. If you have the water heater temperature set too high, your water heater is forever heating a tank brimming with super-hot water.

What's the Right Temperature for My Hot Water?

More often than not, the suggested efficient temperature of 120 degrees is a good setting for your water heater. At 120 degrees, the water is warm enough to meet the needs of most members of the household, but not so hot that it risks burning skin on contact. This makes it a safer option, especially in homes with young children or elderly people. Cooler temperatures also decrease mineral deposits in your water heater, which could cause it to break down or need replacing.

Can I Raise My Water Temperature Hotter Than 120 Degrees?

While many energy experts say 120 degrees is the ideal water heater temperature if you’re wanting to save money, is it OK to set it higher? Apart from personal preference, there are some scenarios where it could be a good idea to set your water temperature a little higher, between 130-140 degrees:

  • Bacteria: Higher water temperatures can be beneficial in eliminating harmful bacteria that can cause or aggravate certain health conditions. This also may be useful if you know your home has an issue with bacteria, or if any residents of the house have a compromised immune system.
  • High usage: If your home tends to use a large volume of hot water simultaneously—showering while also running the dishwasher and washing machine, for example—a greater water heater temperature may be necessary to make sure there’s enough hot water for everyone.
  • Old dishwasher: If your dishwasher is an older model and doesn’t heat water on its own, you may have to set your water heater to a higher temperature for it to work effectively.

What Temperature Is Too High?

Even though some people like their water quite hot or like to blend hot and cold water to achieve their desired water temperature, there is such a thing as water that is too hot. Experts say any temperature hotter than 140 degrees is too hot for a water heater in a residence. At 150 degrees, which is regarded as way too hot, it takes a few seconds for the water to create third-degree burns. This is why a water heater temperature of 150 degrees is considered very dangerous in households with children or the elderly.
