Do Tankless Gas Water Heaters Need Electricity

The short answer is yes a gas tankless water heater needs electricity to work.

Do tankless gas water heaters need electricity.

Tankless gas water heaters have an internal pc board electronic ignition and an electronic thermostat which is required to operate the water heater. Also the digital remote and pc board it uses are powered by electricity. Even though the water heater uses natural gas as its primary fuel some models do indeed use electricity to get the pilot light burning. Without a power source these components will not operate preventing the tankless water heater from producing hot water.

They also need sensors to activate the heating process and keep up the heat as long as the water keeps running to produce consistent hot water flow. Hence tankless gas water heaters need electricity to work. Although it is mainly powered by natural gas it does need electricity to function. This can only happen through the help of an electric current.

In the operation of a tankless gas water heater the heat exchanger needs to sense the flow of the water to get activated and send heat generated by the gas burner to the flowing water. Most traditional tank systems also need electricity. No a tankless gas water heater still requires some electricity to operate. Most of the modern gas water heaters especially if tankless do need electric current for ignition.
