Commercial Radiant Heating Systems — Installation & Service

A 40x60 shop is 2,400 square feet, but BTU needs depend on ceiling height, insulation, door openings, climate, fuel type, and desired temperature. Commercial radiant systems may use different sizing than forced-air units because they heat objects and occupied zones directly. Combustion Research Corporation offers systems from 30,000 BTUs to 250,000 BTUs and engineering support to size the right configuration.

Combustion Research Corporation offers gas-fired vacuum radiant infrared tube systems, power-vented tube heaters, high-intensity single-stage and dual-stage heaters, and electric Solaira heaters. Available options include natural gas, LP/propane, straight or U configurations, and systems ranging from smaller commercial spaces to very large warehouses, hangars, docks, and industrial buildings.

Radiant infrared heating systems can reduce operational heating costs by 30-50% compared with conventional heating systems, according to the company’s product documentation. Savings are achieved by directing heat toward people, floors, equipment, and work zones rather than primarily heating large volumes of air, which is especially valuable in high-bay or frequently opened commercial spaces.

Yes. Combustion Research Corporation systems are designed for demanding commercial and industrial applications, including large warehouses, steel warehousing, aircraft hangars, service garages, auto dealerships, greenhouses, shipping and receiving docks, car and truck wash bays, oil and lube shops, and similar facilities. Custom designs can support spaces from approximately 500 square feet to very large buildings.

Vacuum-vented systems, such as Reflect-O-Ray, are custom-designed gas-fired radiant tube systems for optimum comfort and fuel efficiency. Power-vented systems, such as Omega II, are unitary radiant tube heaters with available BTU inputs from 105K to 200K. The best choice depends on building layout, venting strategy, heat load, installation requirements, and system design goals.

Radiant tube heaters are designed for durability and simplified upkeep. Combustion Research Corporation highlights low-intensity systems with no built-in maintenance components like filters or condensation-prone tube replacements. Features such as electronic flame monitoring, corrosion-resistant aluminized steel tubing, pre-purge cycles, and factory testing help support reliable long-term operation when installed and serviced properly.

Several radiant tube heater products include a 10-year warranty on radiant tubes for internally created corrosion, while Synergy high-intensity heaters list a 1-year limited warranty. Warranty terms vary by product line and component, so the selected system should be reviewed during specification to confirm applicable coverage, installation requirements, and warranty conditions.

Yes. Radiant infrared heating warms surfaces, people, and objects without relying on the same air movement as many forced-air systems. This can help reduce the circulation of dust and airborne pathogens, making it useful for shops, warehouses, animal confinement, greenhouses, service areas, and facilities where air quality, cleanliness, or occupant comfort matters.
