Industrial & Commercial Warehouse Heaters

Vacuum-fired systems use an exhauster to draw combustion gases through the tube, offering flexible venting for large or complex buildings, while power-vented units push exhaust directly outside through a shorter run, simplifying installation in smaller facilities with strong per-unit BTU output.

Single-stage heaters run at one fixed output, ideal for consistent heating loads, while dual-stage (2-stage) units modulate between high and low fire based on ambient temperature, reducing fuel consumption and providing faster recovery when temperatures drop—best suited for variable-load applications.

Many models, including the Synergy Series, require no direct venting, reducing roof penetrations and installation costs. Vacuum-fired and power-vented Reflect-O-Ray and Omega II systems do require exhaust venting, engineered to run efficiently through walls or roofs depending on building layout and code requirements.

Stainless steel construction is recommended for corrosive environments such as car washes, natatoriums, ice arenas, and chemical processing facilities where humidity, chlorine, or road salt exposure would degrade standard powder-coated housings faster, extending equipment life in harsh conditions significantly.

Most units operate on natural gas or LP/propane gas, with select models available in oil-fired configurations for off-grid or rural facilities lacking natural gas utility access, giving facility managers flexibility based on their available fuel infrastructure and site location.

Combustion Research Corporation backs radiant tubes with a 10-year warranty against internally created corrosion, plus additional warranties ranging from 1 to 3 years on burner components, ignition controls, and electrical systems depending on the specific model and configuration selected.
