Electronic ignition is a modern gas ignition system used in water heaters, furnaces, and boilers to replace a standing pilot light. It ignites the burner only when heat is needed, reducing gas use and improving safety. Common types include intermittent pilot and hot surface ignition, both designed for reliable starts and higher efficiency.

What is electronic ignition in a gas water heater?
It’s an on-demand ignition system that lights the burner only when needed, replacing a constant pilot flame.

Electronic ignition saves fuel by firing only on demand.
A homeowner upgrades a gas furnace and water heater to electronic ignition and notices lower gas use because pilot flames no longer burn continuously.
If ignition fails, check the gas supply and error codes before servicing. Avoid DIY repairs on gas or electrical components.

Electronic ignition systems were adopted widely to improve efficiency and reduce the safety risks of standing pilot flames.
Is electronic ignition safer than a pilot light?
Yes. It eliminates a constant flame and only ignites when heat is needed.
What happens if the power goes out?
Most electronic ignition systems will not operate without power.
Can I clean electronic ignition components myself?
Light dusting is okay, but repairs and adjustments should be done by a professional.
