Most gas water heaters do not use electricity to operate. However, many of them rely on a minimal amount of electricity to get their pilot light burning in order to light their igniter. So although the gas heater doesn’t need electricity to run, it does need a minimal amount of electricity to start it.

Even though the water heater uses natural gas as its primary fuel, some models do indeed use electricity to get the pilot light burning. This piezoelectric starter makes a spark, which ignites the natural gas to start heating the water you'll use to take your nice warm shower. Advertisement.

The short answer is, yes, a gas tankless water heater needs electricity to work. Most traditional tank systems also need electricity. If your pilot light is fired up by your power source then you need to be on the grid.

No, a tankless gas water heater still requires some electricity to operate. Tankless gas water heaters have an internal PC board, electronic ignition, and an electronic thermostat that requires electricity to operate. Without a power source, these components will not operate, preventing the tankless water heater from producing hot water.

Gas water heaters don’t use electricity as a fuel, and many homeowners assume they will work in a power outage. This depends on your gas water heater type. If your gas water heater uses a continuous gas pilot light, it is likely that your gas water heater will continue to function normally in the event of a power outage.

Water heater maintenance is an important step to keep your natural gas bill under control. Although heaters that run on natural gas use less energy and are more cost-effective than electric water heaters, they aren’t necessarily problem-free. High gas bills could still be a concern if you don’t maintain your water heater properly.

To power the sparking igniter, in order to ignite the gas, most continuous flow through hot water heaters are connected to your home’s power supply. However, there are some flow through hot water heaters that use energy created by the water flowing through a small water turbine to provide the power for ignition (see graphic).

Modern gas water heaters usually have an electronic igniter to ignite the gas, whereas older models have a pilot tube with a pilot light that is always burning. Models with a pilot tube also have a thermocouple, which is a safety device that turns off the gas if the pilot goes out.

Gas and electric water heaters both supply hot water to your home. The gas variety provides the heat by burning fuel provided through a gas line and the electric type generates the heat through electric resistance coils. Electric water heaters are usually a little smaller than their gas counterparts.
