Adjusting Temperature On Electric Water Heater

Immediate action is crucial: Numerous reports indicate scalding incidents are directly linked to improperly adjusted electric water heater temperatures. Homeowners must check and adjust their water heater settings to mitigate the risk of severe burns.

This article provides a concise guide on how to safely adjust your electric water heater, preventing potential scalding and reducing energy waste. Understanding the correct temperature and adjustment process is paramount for household safety and efficiency.

Understanding the Risks: Scalding and Energy Waste

The U.S. Consumer Product Safety Commission (CPSC) warns that water temperatures above 120°F (49°C) can cause serious burns. Children and the elderly are particularly vulnerable.

Furthermore, excessively high water heater temperatures result in unnecessary energy consumption. This leads to inflated utility bills.

The Ideal Temperature: 120°F (49°C) Recommended

Experts, including the American Society of Sanitary Engineering (ASSE), recommend setting your electric water heater to 120°F (49°C). This minimizes scalding risks while maintaining adequate hot water supply.

Confirm your current temperature setting before making any adjustments.

Step-by-Step Guide: Adjusting Your Electric Water Heater

1. Locate the Thermostat Access Panel

Turn off the circuit breaker supplying power to your water heater. This prevents electrical shock during the adjustment process.

Find the thermostat access panel, usually located behind a removable plate on the side of the tank. You might need a screwdriver to remove the plate.

2. Remove Insulation and Protective Cover

Carefully remove any insulation covering the thermostat. Then, detach the protective plastic cover to expose the thermostat dial.

Note the original temperature setting before making any changes. This acts as a reference point if you need to revert later.

3. Adjust the Thermostat

Use a screwdriver to adjust the thermostat dial to 120°F (49°C). Most thermostats have a clear temperature marking.

Some water heaters have two thermostats (upper and lower). Both must be adjusted to the same temperature for consistent performance. Consult your user manual for specific instructions.

4. Reassemble and Restore Power

Replace the protective cover and insulation. Secure the access panel with the screws.

Turn the circuit breaker back on to restore power to the water heater. Allow several hours for the water to reach the new temperature.

5. Test the Water Temperature

After a few hours, test the water temperature at a faucet located farthest from the water heater. Use a thermometer to ensure the temperature is approximately 120°F (49°C).

If the temperature is significantly different, repeat the adjustment process. Check your water heater's manual if problems persist.

Troubleshooting Common Issues

No Hot Water: Check the circuit breaker and thermostat settings. A tripped breaker or faulty thermostat could be the cause.

Water Too Hot: Verify the thermostat is set correctly. A malfunctioning thermostat may require replacement.

Rusty Water: This could indicate corrosion inside the tank. A professional inspection is recommended to assess the water heater's condition.

Professional Assistance

If you are uncomfortable performing these adjustments yourself, contact a qualified plumber or electrician. Licensed professionals can ensure the job is done safely and correctly.

Ignoring these risks can lead to severe burns and property damage. Don't hesitate to seek professional help if needed.

Ongoing Safety Measures

Regularly check your water heater's temperature. This ensures it remains within the safe range and optimizes energy efficiency.

Install anti-scald devices on faucets and showerheads, especially in homes with young children or elderly individuals. These devices automatically limit water temperature to prevent burns.
