30 ft 100000 BTU Gas Radiant Tube Heaters

Sizing depends on ceiling height, insulation, square footage, and desired temperature rise. As a general rule, 100,000 BTU units cover roughly 2,500-4,000 sq ft depending on conditions. A proper heat loss calculation, which manufacturers like Combustion Research Corporation offer as a service, ensures accurate BTU sizing for your specific facility.

Power vented systems use a blower to push combustion gases through the tube and out a vent, while vacuum fired (vacuum vented) systems use an exhauster to pull gases through, creating a negative pressure draft. Vacuum fired designs are typically favored for larger, custom-engineered systems and high-bay applications exceeding 20 ft ceilings.

Most models run on natural gas (NG) or propane (LP), configurable at the factory or in the field. Combustion Research Corporation also offers an oil-fired vacuum fired option for off-grid or rural facilities without natural gas access, such as remote agricultural or military installations.

Yes, stainless steel burner housing and tubing variants are specifically engineered for corrosive, high-humidity, or chloramine-exposed environments such as car wash bays, natatoriums, and ice arenas. These models resist internal and external corrosion far better than standard powder-coated units in wet or chemically aggressive settings.

Combustion Research Corporation backs its radiant tubes with a 10-year warranty against internally created corrosion, plus a 3-year warranty on ignition controls, electrical components, and burner assemblies, reflecting confidence in long-term durability under continuous industrial use.

Standard safety features include 3-try direct spark ignition with 100% safety lockout, electronic flame monitoring, pre-purge cycles, and burner flame inspection windows. These features ensure safe automatic shutdown in the event of ignition failure and continuous monitoring during operation.
