How to Adjust Your Hot Water Heater
Before we get started, it’s important to note that adjusting your hot water heater can be dangerous if not done properly. If you’re not comfortable, or don’t have experience working with hot water heaters, it’s best to call a professional plumber.
Step 1: Turn off the power supply
The first step in adjusting your hot water heater is to turn off the power supply. If your hot water heater is electric, turn off the breaker. If it’s gas, turn off the gas supply valve.
Step 2: Locate the temperature control knob or thermostat
The temperature control knob or thermostat is usually located on the front of the hot water heater. It may be a dial or a digital display.
Step 3: Adjust the temperature
To adjust the temperature, turn the dial or press the buttons on the digital display. Most hot water heaters have a range between 120°F and 140°F. For most households, a temperature of 120°F is sufficient.
Note: Be careful not to set the temperature too high, as this can create a scalding hazard.
Step 4: Wait for the water to heat up
After adjusting the temperature, wait for the water to heat up. This can take a few hours depending on the size of your hot water heater and the starting temperature of the water.
Step 5: Test the water temperature
Once the water has heated up, test the temperature with a thermometer or by feeling the water. If the water is still too hot or too cold, adjust the temperature control knob again and wait for the water to heat up.
Step 6: Repeat as necessary
If you find that you need to adjust the temperature frequently, you may need to replace the temperature control knob or thermostat. Consult with a professional plumber for assistance.
