Turning down a hot water tank can be an effective way to save on energy bills and increase safety in your home. Adjusting the temperature setting not only conserves energy but also reduces the risk of scalding. This guide will help you understand how to safely and efficiently adjust your hot water tank settings.
How to Adjust Your Hot Water Tank Temperature
Why Should You Turn Down Your Hot Water Tank?
Lowering the temperature on your hot water tank can lead to significant energy savings. According to the U.S. Department of Energy, reducing the temperature from 140°F to 120°F can save you up to 10% on your water heating costs. Additionally, a lower temperature reduces the risk of scalding, making your home safer, especially for children and the elderly.
Steps to Turn Down Your Hot Water Tank
Adjusting the temperature on your hot water tank is a straightforward process. Here’s how you can do it safely:
-
Locate the Thermostat: Most hot water tanks have a thermostat located behind an access panel. For electric tanks, you may need to remove a small screw to access it.
-
Check the Current Setting: Before making any changes, note the current temperature setting. This way, you can revert to it if necessary.
-
Adjust the Temperature: Use a flathead screwdriver to turn the dial. For optimal energy savings and safety, set the temperature to 120°F.
-
Replace the Access Panel: Once the adjustment is made, securely replace the access panel to ensure safety.
-
Test the Water Temperature: After a few hours, check the water temperature at the tap to ensure it aligns with your desired setting.
Benefits of Lowering Your Hot Water Temperature
- Energy Efficiency: Lowering the temperature reduces the energy needed to heat water, decreasing your utility bills.
- Safety: Reduces the risk of burns from excessively hot water.
- Environmental Impact: Using less energy means a smaller carbon footprint.
