Commercial radiant tube heater in an industrial facility

Our Radiant Tube Heater Services

Compare Combustion Research radiant tube heater families for commercial, industrial, agricultural, and high-bay heating applications.

Reflect-O-Ray

Combustion Research’s flagship vacuum gas-fired radiant tube system is custom-engineered for large commercial, industrial, agricultural, warehouse, hangar, and corrosive-environment applications requiring efficient, even infrared coverage.

Omega II

Omega II power-vented radiant tube heaters provide unitary gas-fired infrared heating for commercial and industrial zones where custom vacuum engineering is not required but energy-efficient radiant comfort is essential.

Serengeti-IR

Serengeti-IR delivers compact 40K-60K BTU power-vented radiant tube heating for smaller commercial bays, workshops, agricultural buildings, detail bays, and light-industrial spaces.

Engineered Heat

Choose the Right Radiant Tube Heater

Radiant tube heaters are built for facilities where conventional forced air wastes energy through tall ceilings, open doors, or exhaust loads. Combustion Research Corporation offers vacuum, power-vented, and compact gas-fired systems engineered around square footage, mounting height, fuel source, and facility conditions, helping owners improve comfort while reducing operating costs by 30-50% versus conventional heating.

"Our 16-bay garage runs with doors opening constantly, so keeping students comfortable through Connecticut winters was a real challenge. Reflect-O-Ray units installed over each bay solved it. The concrete floor acts as a heat sink, absorbing and re-radiating warmth back into the space, so students feel warm at lower thermostat..."

Ella T. Grasso Technical School

"We chose a two-stage Omega II 30-ft low intensity tube system for our new two-story hospital, and it's been the right call. The 60,000–100,000 MBH output keeps our rear operating area genuinely comfortable, not just warm air blowing around. Our concrete slab absorbs and re-radiates the heat, so the space..."

Fenton River Veterinary Hospital

"Hangars are the hardest buildings to heat. High bay, minimal insulation, and a massive overhead door that dumps cold air in every time it opens. Forced air simply couldn't keep up without burning through energy. Ten 40-foot straight tubes at 150 MBH with reflectors changed that completely. Radiant heat warms..."

Tac Air – Bradley International Airport

"Heating a 120-yard indoor field under a 65-foot domed roof is not a standard job, and Reflect-O-Ray was the only system engineers felt could be tailored to it. Twelve 360,000 B/H burners firing 140-foot tubes condition the entire space efficiently. Infrared fit directly into our campus energy conservation standards and..."

Frequently Asked Questions

What ceiling height is needed for radiant tube heater?

Most low-intensity radiant tube heaters are commonly mounted from about 10 to 30 feet, depending on model, BTU input, building use, and required clearances. Combustion Research recommends Reflect-O-Ray 6.0 EDS for high-bay spaces with 20-foot-plus ceilings. Synergy high-intensity ceramic systems typically fit 8- to 20-foot mounting heights for spot or zone heating.
