Do new gas water heaters have pilot lights?

The use of standing pilots has been removed from most modern water heaters. They use an electronic device to start a fire. Don’t try to light the electronic ignition system on your own.

Do new heaters have pilot lights?

A traditional pilot light is not used in newer gas furnaces. They use electronic ignition systems that only light up when necessary. Constant flame heating systems can still be repaired in most cases.

Does my hot water heater have a pilot light?

There isn’t a gas or pilot light involved in electric water heating. If the power is off, you may need professional help with an electrical problem.

Where is my pilot light on my water heater?

Why is the pilot light on a tankless water heater wasted?

The pilot light of a tankless water heater is wasted energy because it is not heating water until demand calls for it and the main burner ignites. For a storage water heater, the pilot light serves as standby heat, keeping the water warm at times of no demand.

How does a tankless water heater work?

A tankless water heater, or on-demand water heater, has no storage tank. Opening a hot-water faucet creates a flow of water through the water heater. This triggers the ignition of the gas burner that heats between 1 and 5 gallons of water per minute depending on the make and model.

How does a pilot light work?

When the main burner extinguishes, the pilot light continues burning. It works using a thermocouple device. The thermocouple device, when heated, provides a small amount of voltage to a pilot solenoid valve. If the flame goes out, the voltage stops, and the pilot valve closes.

What is a standing pilot gas valve?

They are reliable and effective to safely light the main burners of a gas furnace, boilers, or water heaters. While the standing pilot gas ignition systems are prone to problems with proper maintenance, the standing pilot gas ignition systems are reliable for many years. Especially if proper and routine maintenance happens on these systems.

What is a problem with a pilot gas ignition system?

Most often, if there is a problem with the standing pilot gas ignition system, it is with the thermocouple or thermopile. These flame-proofing components need to replacing when that happens. However, there are situations where the pilot gas line gets fouled or clogged with debris or trash. In that case, the blockage will not permit the proper amount of gas to the pilot tip. A thorough cleaning of the pilot assembly is in order in this situation.

A standing pilot ignition system has a pilot light assembly and a thermocouple or thermopile. The two, thermocouple and thermopile are different but produce the same result. That is always proving the flame. The flame keeps the thermocouple or thermopile hot.

Which is more efficient, standing pilot or electronic ignition?

Electronic ignition gas ignition systems are more efficient than standing pilot gas ignition systems. The electronic ignition gas ignition systems utilize energy only when needed. These systems only utilize electronic ignition only on a call for heat or a call for the gas furnace, gas-fired boiler, or gas-fired water heater to fire. That makes electronic ignition gas ignition systems more efficient than standing pilot systems.
