Electronic Ignition
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.
