25000 BTU Natural Gas Garage Heaters

Natural gas heaters connect directly to a municipal gas supply line, offering lower fuel cost per BTU and continuous supply without tank refills. Propane heaters use stored LP gas, making them ideal where natural gas lines are unavailable. Combustion Research heaters support both fuel types, and manifold pressures differ slightly — natural gas typically operates at 6 inches WC versus 10 inches WC for propane.

Yes. All Combustion Research Corporation heaters are CSA International Design Certified to ANSI/CGA Standards, including compliance with ANSI Z83.20 / CSA 2.34 where applicable. Each unit features 3 Try Direct Spark Ignition with 100% Safety Lockout and electronic flame monitoring, and undergoes 100% factory testing before shipment to ensure safe, reliable operation.

It depends on the model. Power vented and vacuum fired systems such as the Omega II and Reflect-O-Ray series require a venting connection to exhaust combustion gases. However, the Synergy series operates without direct venting, requiring fewer roof penetrations and simplifying installation. All models comply with applicable safety standards for their respective venting configurations.

Combustion Research Corporation provides a 10-year warranty on radiant tubes for internally created corrosion across its product lines. Select models such as the Omega II 9K Series also include a 3-year warranty on ignition controls and electrical components. Standard product warranties of 1 year limited are included with Synergy series heaters. Contact a representative for full warranty documentation.

Combustion Research infrared heaters are engineered for a broad range of applications including residential garages, service garages, aircraft hangars, auto dealerships, car and truck wash bays, warehouses, greenhouses, pole barns, animal confinement facilities, oil and lube shops, natatoriums, and protected outdoor environments such as patios and shipping and receiving docks.

Combustion Research Corporation's infrared tube heaters deliver energy savings of 30–50% compared to conventional forced-air heating systems, with some applications achieving up to 75% savings in energy costs. These savings result from radiant heat delivery directly to occupants and surfaces — reducing heat stratification, minimizing infiltration losses, and eliminating the energy waste associated with heating and circulating large volumes of air.
