Infrared Gas Heaters

Vacuum-fired systems use an exhauster to pull combustion gases through the tube, creating negative pressure for even heat distribution and simplified installation without ductwork. Power-vented systems use a blower to push air/gas through the burner, offering flexible venting options. Both use aluminized or stainless steel tubing and deliver similar energy savings.

BTU requirements depend on ceiling height, insulation, square footage, and climate. Combustion Research Corporation offers models ranging from 30,000 to 250,000 BTU per unit, and provides custom heat loss calculations and system design services to ensure the correct number and placement of heaters for your specific facility.

Yes, most models are available in both natural gas (NG) and propane/LP gas configurations. The burner and gas train are matched to the selected fuel type at the factory, so specify your fuel source when ordering to ensure proper manifold pressure and combustion settings.

Yes. These heaters are CSA Certified (formerly A.G.A & CGA) and comply with ANSI Z83.20/CSA 2.34 safety standards. Features like 3-try direct spark ignition, 100% safety lockout, electronic flame monitoring, and pre-purge cycles ensure safe operation in high-bay industrial and aviation environments.

Most Combustion Research Corporation infrared heaters include a 10-year warranty on radiant tubes against internally created corrosion, plus a 3-year warranty on ignition controls, electrical components, and burner parts. Synergy high-intensity ceramic heaters carry a 1-year limited warranty.

It depends on the system type. Vacuum-fired and power-vented tube heaters vent combustion byproducts through a small-diameter pipe without ductwork. High-intensity ceramic heaters, like the Synergy series, require no direct venting at all, making them suitable for both indoor and protected outdoor applications.
