Furnace Ignitors
Older model furnaces typically used a pilot light to ignite the gas or oil used to heat your home.
Pilot lights have several drawbacks, such as poor efficiency (the pilot light continuously burns
fuel) and occasional unreliability.
Newer furnaces typically use either a hot surface ignitor or an intermittent pilot light.
The articles that follow are profiles of the ignitors and ignition systems manufactured by the most
popular heating and cooling brands.
