Ways to Modify a Hot Water Heater Temperature

Every home has a water heater working quietly behind the scenes to heat water for showering, cooking, cleaning and other household jobs. Does your home’s water feel too hot at the tap? Or, it could be the opposite is true, and the water just won’t get as hot as it should be. You might need to adjust your hot water heater heat level to improve comfort, safety and energy efficiency. Read more to find out why you might need to change the temperature and how to make this simple adjustment based on the type of water heater you have.

Reasons to Adjust Hot Water Heater Settings

Occasionally, you may want to lower the temperature; other times, the hot water might require a boost. According to the US Department of Energy, the most beneficial water heater temperature is between 120 and 140 degrees F, which provides a nice balance between safety and energy efficiency.

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

Reasons to Turn the Temperature Down

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

Why You Should Increase Your Water Heater Temp

• Microbial growth in the tank: Do not set the temperature of your water heater under 120 degrees for an extended time because this causes an environment where unhealthy bacteria can grow.
• Better cleaning: If your dishwasher doesn’t include a built-in heating element, you may need to set your water heater greater than 120 degrees for your dishes to get clean. Hotter water eliminates grease and dirt more successfully and results in better sanitation.
• More hot water for everyone: Raising your water heater’s temperature makes more hot water available. If you’re usually the last person to get ready in the morning and you repeatedly suffer through 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 check your current water temperature. Open the hot water tap at the kitchen sink and hold a cooking thermometer into the water. Often, the temperature at the tap is about 10 degrees lower than the water heater setting due to heat loss as the water flows through your pipes.

Changing the water heater is a simple undertaking with most units. Follow these tips to help you make the proper adjustment.

Adjusting the Temperature on a Tank-Style Water Heater

If you have a gas or electric storage tank, check 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. Turn the knob a little bit to one side or the other, depending on whether you need hotter or cooler water.

Once you’ve made the adjustment, wait three hours to allow the temperature in the tank to stabilize. After that, go find the water temperature at the tap once more. Even though you’re waiting a bit to test the temperature, you can continue using your hot water like normal during this waiting period.

Tankless Water Heater Temperature Adjustment

Modern tankless models commonly have a user-friendly digital control panel with temperature settings you can move up or down simply by pushing a button. Note 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, contemplate adding a second point-of-use unit in the kitchen or bathroom.
