Steps to Adjust a Hot Water Heater Temperature

Every home has a water heater working quietly behind the scenes to warm up water for showering, cooking, cleaning and other household needs. However, does the water in your residence feel too hot at the tap? Maybe the opposite is true, and the water just won’t get as hot as it should be. You could need to change your hot water heater heat level to increase comfort, safety and energy efficiency. Read more to find out why you might want to change the temperature and how to make this easy adjustment based on the type of water heater you have.

Reasons to Adjust Hot Water Heater Settings

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

But where in this range should you set your hot water heater? The answer relies on your household’s specific needs.

Why Should You Turn Down the Water Heater Temperature?

• Safety: A temperature greater than 140 degrees can result in third-degree burns in seconds. Reducing your water heater’s temperature closer to 120 degrees reduces the risk of scalding by water from the tap. While hot water burns can happen to anyone, children and older adults are the most at risk, as their skin is sensitive and can burn more rapidly.
• Maintenance: Turning the temperature off is an essential first step before draining the tank or carrying out other water heater maintenance tasks. After the appliance is off, wait several hours so the water can cool before proceeding so scalding water doesn’t splash on your skin.
• Energy savings: Water heating results in a significant portion of your home’s energy use. Reducing the temperature setting to 120 degrees minimizes your utility expenses without compromising hot water performance. When you aren’t going to be home for a few days, turn down the temperature even more for energy savings while you’re out.

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 unsafe bacteria can grow.
• Better cleaning: If your dishwasher doesn’t come with a built-in heating system, you might need to set your water heater at a temperature more than 120 degrees for your dishes to come out of the dishwasher clean. Hotter water cleans grease and dirt more effectively and results in better sanitation.
• More hot water for everyone: Boosting your water heater’s temperature makes more hot water available. If you’re normally the last family member 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 Change the Temperature on a Hot Water Heater

Before making any adjustments, it’s smart to determine your current water temperature. Open the hot water tap at the kitchen sink and put a cooking thermometer under the water. Often, the temperature at the tap is about 10 degrees less than the water heater setting because the water loses heat as it flows through your pipes.

Altering the water heater is an easy task with many units. Use these tips to help you make the proper adjustment.

Traditional Storage Tank Water Heater Temperatures

If you have a gas or electric storage tank, look near 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. Rotate the knob slightly in one direction or the other, depending on if you want hotter or cooler water.

Following the adjustment, wait three hours for the temperature in the tank to stabilize. Then, check the water temperature at the tap another time. You can continue using your hot water like normal during this waiting period.

Tankless Water Heater Temperature Adjustment

Today’s popular tankless models commonly have a simple-to-use digital control panel with temperature settings you can move up or down with the touch of a button. Be aware that tankless water heaters might not be able to attain the highest settings during cold spells or peak demand times. If you’re struggling with the lower flow rate, consider installing a second point-of-use unit in the kitchen or bathroom.
