The pilot light in your hot water heater does more than simply ignite the gas. Without it, the water heater won’t be able to maintain internal temperatures, allowing the water to cool off.
Does water heater pilot stay on?
Gas and propane fueled water heaters use a small flame to ignite the burner. This small flame is called a pilot light and it stays lit at all times.But once the pilot light is relit, the water heater is able to ignite the gas burner and can begin to heat the water again.

Should the pilot light always be on in a gas heater?
Most furnaces with electronic ignition have a device called a hot surface igniter.The difference is that the flame is only lit (by an electronic spark) when your furnace is ready for a heating cycle. When the pilot light is not needed, it is completely off, saving you money on gas.
What is pilot mode on water heater?
On gas water heaters, the pilot light makes sure that there’s always flame available when the burner needs to kick in and heat water. If you run out of gas, install a new water heater or have to shut it down for some reason, lighting the pilot is the first step to turn on a water heater.
Will gas leak if pilot light is off?
If the pilot light goes out on a storage or instantaneous hot water heater, space heater or a ducted heater, you will not have a gas leak.

Can a pilot light cause a fire?
When the appliance is turned on, a valve releases more gas, which is ignited by the pilot light.If this leak continues, its concentration may reach a point where a spark such as that from a cigarette lighter, static electricity, or even the pilot light itself as it is re-lit will cause a fire or even an explosion.
Can a pilot light cause carbon monoxide?
Carbon monoxide is only produced when fuel of any type; oil, gas, wood or coal is burned.And a pilot light out of adjustment can produce carbon monoxide gas. The amount produced by even a badly maladjusted pilot is small because the flame size is also small.
What makes pilot lights go out?
Improper Venting & Airflow
Sometimes a pilot light can go out as a result of some source of wind or air simply blowing it out. If this happens, there could be an issue with how your flue pipe is set up or how your system is venting.
