Infrared Space Heaters for Large Rooms

The best infrared heater for a large room depends on square footage and application. For spaces up to 50,000 sq ft, power-vented systems like the Omega II PEP 4.0 (105K–200K BTU) are ideal. For facilities exceeding 100,000 sq ft, vacuum-fired systems like the Reflect-O-Ray 4.0 EDS — which covers 500 sq ft to over 1 million sq ft — offer scalable, custom-designed coverage with superior efficiency. Combustion Research Corporation provides engineering support to help size systems correctly for any facility.

A 1,500-watt electric infrared heater is typically rated for small residential spaces of around 150–300 sq ft and is not suited for large commercial or industrial rooms. For large rooms such as warehouses, aircraft hangars, or auto dealerships, gas-fired infrared heaters with BTU outputs ranging from 30,000 to 220,000+ BTU/hr are required. Combustion Research Corporation offers systems in this range specifically engineered for large-scale commercial and industrial heating applications.

BTU requirements depend on ceiling height, insulation, climate zone, and facility size. For moderate-sized commercial spaces, 40K–100K BTU systems are typical. Large warehouses, aircraft hangars, or industrial facilities often require 105K–220K BTU systems. Combustion Research Corporation offers a full range from 30K to 220K BTU and provides engineering support to size systems correctly for your specific space and application.

Power-vented systems use a fan to push exhaust gases out, making them suitable for single-unit installations with direct venting. Vacuum-fired systems use a central exhauster to pull combustion gases through a connected tube network, making them ideal for larger facilities requiring multiple heater zones without multiple roof penetrations. Both configurations are available from Combustion Research Corporation, and the right choice depends on building construction and local codes.

Combustion Research Corporation's CSA-certified infrared heaters deliver 30–50% lower fuel costs compared to conventional forced-air heating systems. This is because infrared heaters warm objects and surfaces directly rather than heating the air, so heat is not lost through drafts or stratification near high ceilings — a common problem in large industrial and commercial spaces.

Every radiant tube heater from Combustion Research Corporation is backed by a 10-year warranty covering internally created corrosion on the radiant tube, along with a 3-year warranty on burner controls and electrical components. All units are factory tested before shipment to ensure reliability. The Reflect-O-Ray EDS series also includes a 3-year burner control warranty in addition to the 10-year radiant tube warranty.

Combustion Research Corporation's infrared heaters are engineered for a wide range of large commercial and industrial applications, including warehouses, aircraft hangars, auto dealerships, oil and lube shops, car and truck wash bays, bump shops, greenhouses, livestock confinement buildings, brooders, pole barns, and protected outdoor patios. Stainless steel housing options are available for high-moisture or corrosive environments such as natatoriums and aquatic centers. Vacuum-fired systems can scale to cover over one million square feet.
