GEI Inc. is a U.S.-based manufacturer of silicon nitride hot-surface ignitors for the HVAC and appliance markets, founded in 1997 and headquartered in Diamond Bar, California.

With over 20 years of experience, GEI specializes in producing high-performance ignitors that serve as direct drop-in replacements for the most widely distributed ignitor SKUs across gas furnaces, water heaters, and appliances. Our silicon nitride ignitors outperform traditional silicon carbide models with significantly longer service life, lower field failure rates, and superior resistance to thermal shock and vibration.

GEI operates its own in-house ceramic core manufacturing, giving us full quality control from raw material to finished product — ensuring consistent specs, tight tolerances, and competitive lead times for OEM and distributor partners.

We supply ignitors to HVAC OEMs, appliance manufacturers, and wholesale distributors across North America. Our products are competitively priced, available in volume, and supported by full cross-reference documentation.
