For lots of people, there’s nothing better than a hot shower in the morning. While that might be a great 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 too hot can squander energy and cost you money. It also can create a safety challenge for members of your home. But, if you set your water heater temperature too low, it can allow growth of potentially harmful bacteria and not supply sufficient hot water for your household.

So, what temperature is the right one for your water heater? Below, 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 home's water heater.

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

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

The U.S. Department of Energy estimates that setting a home water heater temperature at 120 degrees could save roughly 22 percent on energy bills. Energy waste is especially a challenge for water heaters because traditional tank models always heat a tank of water in case it is needed. If you have the water heater temperature set too high, your water heater is consistently heating a tank full of extremely hot water.

What Temperature Should I Set My Hot Water To?

More often than not, the suggested efficient temperature of 120 degrees is an effective yet cost-saving setting for your water heater. At 120 degrees, the water is warm enough to meet the requirements of most members of the household, but not so hot that it could cause burning skin on contact. This makes it a safer alternative, especially in homes with small children or elderly individuals. Cooler temperatures also decrease mineral deposits in your water heater, which could cause it to break down or need replacement.

Can I Raise My Water Temperature Hotter Than 120 Degrees?

While many energy experts say 120 degrees is the preferred water heater temperature if you’re trying to save money, is it alright to set it higher? Apart from personal preference, there are a few scenarios where it could make sense to set your water temperature a little higher, between 130-140 degrees:

  • Bacteria: Increased water temperatures can be a good way to eliminate harmful bacteria that can cause or aggravate certain health conditions. This also may be helpful if you know your home has an issue with bacteria, or if any members of the household have a compromised immune system.
  • 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 hotter water heater temperature may be necessary to make sure there’s adequate hot water for all the household's needs.
  • Old dishwasher: If your dishwasher is an older model and doesn’t heat water itself, it may be necessary to set your water heater to a higher temperature for it to work effectively.

What Temperature Is Too Hot for my Hot Water Heater?

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