A small flame, about the size of a candle flame, burns continuously at the end of a small gas pilot tube. The flame burns directly into a thermocouple, a safety device that allows the main gas valve to open only when the pilot is burning.
Do instant gas hot water systems have a pilot light?
An instant gas hot water heater, also known as a tankless, instantaneous or continuous flow system, only heats water as and when you need it. They have either a pilot flame or electronic ignition and water is heated by a gas burner as it flows through a coiled pipe, otherwise known as a heat exchanger.
How much does it cost to relight a pilot light?

Can water heater pilot light go out?
How does a water heater pilot light work?
During the lighting of the pilot, a button on the valve gets pressed, letting a small amount of gas out. The pilot head uses that gas to light the pilot, which then heats the thermocouple. Eventually, the thermocouple sends out a small electrical current out to the water heater’s control valve.
How does an automatic pilot light work on a furnace?
Unlike older pilot lights, which have to be lighted by hand, automatic pilot lights, now commonly found in most home furnaces, are regulated by a thermostat and only ignite when needed. While older pilots burned constantly, wasting gas, automatic pilot lights come on long enough to ignite…

How does a gas water heater work?
The gas valve the water’s temperature as well as the pilot light. During the lighting of the pilot, a button on the valve gets pressed, letting a small amount of gas out. The pilot head uses that gas to light the pilot, which then heats the thermocouple.
