Overhead Propane Radiant Heaters

A 30,000 BTU overhead propane radiant heater can typically heat approximately 750–1,000 square feet in a well-insulated commercial or industrial space. Actual coverage depends on ceiling height, insulation quality, climate zone, and the number of air exchanges. Combustion Research Corporation offers free heat loss calculation services to size your system accurately.

Power-vented systems use a blower to push combustion gases out through a flue, making them suitable for most commercial and industrial installations. Vacuum-fired systems use an exhauster to draw gases through the entire radiant tube, enabling longer tube runs and custom multi-burner configurations ideal for very large facilities exceeding 500,000 square feet.

Yes. Combustion Research offers stainless steel burner housing and emitter tube options specifically engineered for chloramine-rich natatoriums, high-humidity ice arenas, and corrosive car wash bays. Stainless steel construction resists the accelerated corrosion caused by chlorine byproducts, road salts, and chemical vapors found in these environments.

Yes. All Combustion Research Corporation overhead radiant heaters are CSA International Design Certified to ANSI/CGA Standards, with select tube heater models also complying with ANSI Z83.20 / CSA 2.34. Each unit undergoes 100% factory testing before shipment to verify safe ignition, flame monitoring, and safety lockout functionality.

Combustion Research's product line spans 30,000 BTU/hr up to 250,000 BTU/hr in a single burner unit. Vacuum-fired EDS systems with dual-input modulating burners can be configured in multi-burner arrays to heat facilities from 500 square feet to over one million square feet, making them suitable for small garages through large distribution centers.

Radiant tube heaters include a 10-year warranty on radiant tubes for internally created corrosion and a 3-year warranty on ignition controls and electrical components. Synergy ceramic series heaters include a 1-year limited warranty. All units are 100% factory tested before shipment, and engineering support is available throughout the specification and installation process.
