Steps to Adjust a Hot Water Heater Temperature

Every home has a water heater working quietly in the background to heat water for showering, cooking, cleaning and other household jobs. However, does the water in your residence feel too hot at the tap? Perhaps the opposite is true, and the water never seems to get as hot as it should be. You may need to adjust your hot water heater settings to increase comfort, safety and energy efficiency. Here are some reasons why you might need to change the temperature and how to make this straightforward adjustment based on the type of water heater your home uses.

Why Change Your Hot Water Heater’s Temperature?

At times, you need to lower the temperature; other times, the hot water might require a boost. Per the US Department of Energy, the ideal water heater temperature is between 120 and 140 degrees F, striking a balance between safety and energy efficiency.

Just where within this range should you set your hot water heater? The answer will depend on your household’s individual needs.

Why Should You Turn Down the Water Heater Temperature?

• Safety: A temperature greater than 140 degrees risks third-degree burns within seconds. Lowering your water heater’s temperature closer to 120 degrees lowers the risk of scalding from the tap. Even though scalding can happen to anyone, children and older adults are the most at risk, as their skin is sensitive and can burn more quickly.
• Maintenance: Turning the temperature off is a crucial first step before draining the tank or doing other water heater maintenance tasks. As soon as the water heater is off, wait several hours to allow the water to cool before beginning maintenance so scalding water doesn’t splash on your skin.
• Energy savings: Water heating accounts for a major portion of your home’s energy use. Reducing the temperature setting to 120 degrees decreases your utility expenses without compromising hot water performance. When you aren’t going to be home for a few days, lower the temperature even more for energy savings while you’re away.

Reasons to Turn the Temperature Up

• Microbial growth in the tank: Don’t set your water heater under 120 degrees for an extended time because this produces an environment where harmful bacteria can grow.
• Better cleaning: If your dishwasher doesn’t include a built-in heating system, you may need to set your water heater greater than 120 degrees for your dishes to come out of the dishwasher clean. Hotter water eliminates grease and dirt more effectively and provides better sanitation.
• More hot water for everyone: Boosting your water heater’s temperature makes more hot water available. If you’re normally the last one to get ready in the morning and you typically get stuck with lukewarm showers, try turning the water heater setting up to 140 degrees.

How to Adjust a Hot Water Heater

Before making any modifications, it’s smart to check your current water temperature. Turn on the hot water tap at the kitchen sink and place a cooking thermometer in the flow. Often, the temperature at the tap is about 10 degrees less than the water heater setting due to heat loss as the water flows through your pipes.

Adjusting the water heater is an easy task with most units. Stick to these recommendations to help you make the right adjustment.

Traditional Storage Tank Water Heater Temperatures

If your water heater has a gas or electric storage tank, inspect the bottom of the tank for a temperature dial. You might see “Low” on one end and “Very Hot” on the other, with letter and symbol markings in between. Turn the knob just a little in one direction or the other, depending on whether you need hotter or cooler water.

After the adjustment, wait three hours for the temperature in the tank to stabilize. Next, test the water temperature at the tap another time. Feel free to continue using your hot water like normal even though you are waiting.

Tankless Water Heater Temperature Adjustment

Today’s popular tankless models usually have an easy-to-use digital control panel with temperature settings you can move up or down simply by pushing a button. Note that tankless water heaters may not be able to reach the highest settings during cold spells or peak demand times. If you’re having problems with the lower flow rate, contemplate installing a second point-of-use unit in the kitchen or bathroom.
