DIY Water Heater Savings: 7 Steps to Lower Gas Temperature and Cut Costs

Gas water heaters are a common household appliance, but they can be energy guzzlers. One way to reduce energy consumption is to lower the water heater temperature. This simple adjustment can save you money on your utility bills and extend the life of your water heater.

Safety First

Before adjusting the temperature, ensure you follow all safety precautions. Turn off the gas supply to the water heater and allow it to cool before touching any components.

Identifying Your Water Heater Type

There are two main types of gas water heaters: storage tank and tankless. Storage tank water heaters hold a reserve of hot water, while tankless water heaters heat water on demand. The temperature adjustment procedure varies depending on the type of water heater you have.

Adjusting Storage Tank Water Heater Temperature

1. Locate the Thermostat: The thermostat is usually a dial or knob located on the front or side of the water heater.
2. Turn Off the Gas: Turn off the gas supply to the water heater.
3. Remove the Thermostat Cover: Carefully remove the cover that protects the thermostat.
4. Adjust the Thermostat: Turn the thermostat dial or knob to the desired temperature. Most manufacturers recommend setting the temperature between 120°F and 140°F.
5. Replace the Thermostat Cover: Securely replace the thermostat cover.
6. Turn On the Gas: Turn on the gas supply to the water heater.

Adjusting Tankless Water Heater Temperature

1. Locate the Control Panel: The control panel is usually located on the front of the water heater.
2. Enter the Temperature Menu: Follow the instructions on the control panel to enter the temperature adjustment menu.
3. Set the Desired Temperature: Use the buttons on the control panel to set the desired water temperature.
4. Confirm the Temperature: Verify that the temperature is correctly set and then exit the menu.

Other Tips for Lowering Water Heater Temperature

• Use a Low-Flow Showerhead: Low-flow showerheads reduce water flow, which can help lower the temperature of the water coming out of the faucet.
• Insulate Hot Water Pipes: Insulating hot water pipes can help prevent heat loss, which can result in lower water temperatures.
• Set the Temperature on Your Dishwasher and Washing Machine: Most dishwashers and washing machines have temperature settings. Setting these appliances to lower temperatures can reduce the amount of hot water used.

Benefits of Lowering Gas Water Heater Temperature

• Energy Savings: Lowering the water heater temperature can significantly reduce energy consumption, leading to lower utility bills.
• Extended Water Heater Life: Operating a water heater at a lower temperature reduces stress on the components, extending its lifespan.
• Reduced Scalding Risk: Water temperatures above 140°F can cause scalding injuries. Lowering the temperature reduces the risk of burns.
• Improved Efficiency: Lower water temperatures improve the efficiency of appliances that use hot water, such as washing machines and dishwashers.

Troubleshooting

If you encounter any issues after adjusting the water heater temperature, here are some troubleshooting tips:

• Water is not hot enough: Check if the thermostat is set correctly. If the thermostat is set to a low temperature, adjust it accordingly.
• Water is too hot: If the water is too hot, even after adjusting the thermostat, there may be an issue with the thermostat or other components. Contact a qualified plumber for assistance.
• No hot water: If there is no hot water, check if the gas supply is turned on and if the pilot light is lit. If the pilot light is not lit, follow the manufacturer’s instructions to relight it.

What People Want to Know

1. What is the recommended water heater temperature for energy efficiency?

120°F to 140°F.

2. How can I tell if my water heater temperature is too high?

If the water coming out of the faucet is scalding or if you notice steam coming from the water heater, the temperature may be too high.

3. Can I lower the water heater temperature on my own?

Yes, you can lower the water heater temperature yourself by following the steps outlined in this guide. However, if you are not comfortable working with gas appliances, it is recommended to contact a qualified plumber.
