How to turn on a gas water heater
1. Find the Pilot Light Access Panel
Near the base of the gas heater, locate the small door or access panel. Remove the cover or open it to view the pilot assembly.
2. Turn the gas valve to “Pilot”.
Rotate the Pilot knob or valve to the Pilot. You may need to press down the knob on some models to activate it.
3. Relighting the Pilot Light
Hold the button down for 30-60 seconds after ignition. Then release the button gently.
4. Turn on the gas control
After the pilot flame has been lit, turn the gas knob to the On setting. Usually, you’ll hear the main burner start up shortly after.
5. Replace the Access Panel
Check that the flame is blue and steady.
6. Check the water tank
To release trapped air, turn on a nearby water tap. If the water is flowing steadily, then your heater has been working correctly.
How to turn on an electric water heater
1. Check your water supply
Verify that the valve for cold water and the pipe are fully open. If the water is flowing smoothly, you can confirm that the tank has been filled by running the hot-water faucet.
2. Turn on Power
Switch the electric water heater on by flipping the On switch at the circuit breakers.
3. Thermostat Set
Remove the thermostat cover, and set the temperature at around 120degF (49degC). This is a safe and efficient level for most homes.
4. Wait for the water to heat up
Let your heater warm the water for 30-60 minutes. It may take longer for larger tanks or newly drained units to reach the desired temperatures.
Check the water supply and temperature settings.
Review these details after turning on your water heater:
- Your heater’s valve should be fully opened.
- The valve for pressure relief must not leak.
- Temperatures around 120°F are considered safe for use in the home.
Check if you can still get hot water an hour later. It may be that the Pilot light is out, or the Heating element might be defective.

A pilot light can go out for many reasons, including a draft or dirt accumulation. How to safely relight the pilot light:
