For quite a few people, there’s nothing better than a hot shower to get the morning started. While that might be a great way to wake up and start the day, experts say it’s possible to set your water too hot.

Setting your water heater to a temperature that’s above the recommended degree can squander electricity and cost you money. It also can create a safety challenge for members of your residence. 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 dwelling.

So, what number is the right one for your water heater? Here, we’ll establish the most efficient temperature to use, when there could be reason to set it a little higher and how hot is too hot for your personal water heater.

What Is the Most Efficient Temperature for a Water Heater?

Although many brands encourage setting the water temperature at 140 degrees, a better temperature for a water heater is 120 degrees Fahrenheit. Experts say 120 degrees strikes the right balance between safety and energy consumption.

The U.S. Department of Energy states that setting a home water heater temperature at 120 degrees could save up to 22 percent on a home's utility bills. Energy waste is a frequent challenge for water heaters because traditional tank models continuously heat a tank of water in case it is needed. If you have the water heater temperature set too high, your water heater is forever heating a tank full of very hot water.

What's the Right Temperature for My Hot Water?

In many instances, the suggested efficient temperature of 120 degrees is the right setting for your water heater. At 120 degrees, the water is heated enough to meet the desires of most homes, but not so hot there's a danger of burning skin on contact. This makes it a safer alternative, 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 replacing.

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

While many industry experts say 120 degrees is the preferred water heater temperature if you’re looking to save money, is it acceptable to set it higher? Apart from personal preference, there are a couple of different scenarios where it could be a good idea to set your water temperature a little higher, between 130-140 degrees:

  • Bacteria: Hotter water temperatures can be helpful in eliminating harmful bacteria that can cause or aggravate certain health conditions. This also may be useful 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 is inclined to use a lot of hot water all at once—showering while also running the dishwasher and washing machine, for example—a higher water heater temperature may be necessary to make sure there’s adequate hot water to go around.
  • Old dishwasher: If your dishwasher is old and doesn’t heat water on its own, you may have to set your water heater to a higher temperature for it to work properly.

How Hot Is Too Hot for a Water Heater?

Although some people like their water quite hot or would rather blend hot and cold water to create their perfect water temperature, there is such a thing as water that is too hot. Plumbing and heating specialists say any temperature higher than 140 degrees is too hot for a water heater in a residential dwelling. At 150 degrees, which is regarded as way too hot, it takes a few seconds for the water to cause third-degree burns. This is why a water heater temperature of 150 degrees is particularly unsafe in homes with children or the elderly.
