For lots of people, nothing feels quite as good as a hot shower to get the morning started. Even though that may be a fantastic way to wake up and start the day, experts say you should be careful not to set your water too hot.

Setting your water heater to a temperature that’s scorching can squander electricity and cost you money. It also can pose a safety challenge for members of your residence. But, if you set your water heater temperature too low, it can allow growth of potentially harmful bacteria and not produce enough hot water for your dwelling.

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

What Is the Most Efficient Temperature for a Water Heater?

Although many brands advise setting the water temperature at 140 degrees, a more economical temperature for a water heater is 120 degrees Fahrenheit. Specialists say 120 degrees strikes the right balance between safety and energy consumption.

The U.S. Department of Energy estimates that setting a home water heater temperature at 120 degrees could save up to 22 percent on energy bills. Energy waste is a frequent challenge for water heaters because traditional tank models always heat a tank of water in case it is required. If you have the water heater temperature set too high, your water heater is forever heating a tank filled to the brim with extremely hot water.

What Temperature Should I Set My Hot Water To?

In many instances, the suggested efficient temperature of 120 degrees is a good setting for your water heater. At 120 degrees, the water is heated enough to meet the requirements of most residents, but not so hot there's a danger of burning skin on contact. This makes it a safer option, especially in homes with young children or elderly individuals. Lower temperatures also cut down on mineral deposits in your water heater, which could cause it to break down or need to be replaced with a new one.

Should You Ever Set Your Water Temperature Higher Than 120 Degrees?

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

  • Bacteria: Increased water temperatures can be beneficial in eliminating harmful bacteria that can cause or aggravate certain health conditions. This also may be practical if you know your home has trouble with bacteria, or if any people who live in your home are sick.
  • High usage: If your home has a tendency to use a significant amount of hot water simultaneously—showering while also running the dishwasher and washing machine, for example—a higher water heater temperature may be necessary to make sure there’s enough hot water for all the household's needs.
  • Old dishwasher: If your dishwasher is getting up there in years and doesn’t heat water as part of its process, you may need to set your water heater to a higher temperature for it to work correctly.

How Hot Is Too Hot for a Water Heater?

Even though some people like their water very hot or would rather blend hot and cold water to obtain their perfect water temperature, there is such a thing as water that is too hot. Plumbing and heating specialists say any temperature above 140 degrees is too hot for a water heater in a home. At 150 degrees, which is considered way too hot, it takes just seconds for the water to cause third-degree burns. This is why a water heater temperature of 150 degrees is considered very hazardous in households with children or the elderly.
