Industrial Warehouse Heating Solutions

A 40x60 shop (2,400 sq ft) typically requires between 60,000 and 120,000 BTU depending on your climate zone, ceiling height, insulation level, and number of door openings. A well-insulated shop in a mild climate may need 70,000–80,000 BTU, while a poorly insulated structure in a cold region can require 100,000–120,000 BTU. A professional heat loss calculation is recommended for accurate sizing.

Warehouses most commonly use gas-fired low-intensity infrared radiant tube heaters. These ceiling-mounted units heat surfaces and occupants directly via radiant energy rather than warming the air, making them highly efficient in large, drafty spaces. They are available in power-vented, vacuum-fired, single-stage, dual-stage, and modulating configurations to match various facility sizes and operational requirements.

Power-vented systems use a powered exhauster that pushes combustion gases through the tube and out a flue, making them simple to install as pre-engineered packages. Vacuum-fired systems use a vacuum exhauster that pulls gases through the tube, allowing for longer tube runs and custom configurations capable of heating spaces from 500 to over 1,000,000 square feet.

Not all models do. The Synergy series of ceramic radiant heaters requires no direct venting, meaning fewer roof penetrations and the ability to use them in protected outdoor environments. Power-vented and vacuum-fired radiant tube heaters do require a flue exhaust connection but offer flexible venting configurations including straight and U-bend arrangements.

Yes. Several models are compliant with NFPA 30A and NFPA 52 standards when installed at code-compliant mounting heights, making them suitable for CNG repair facilities and auto service bays. All units feature 100% safety lockout ignition systems and electronic flame monitoring to meet commercial and industrial safety requirements.

All heaters in this product line are available for both Natural Gas (NG) and Propane Gas (LP) operation. Fuel type selection affects minimum and maximum inlet pressure requirements, so it is important to confirm your on-site gas supply specifications when selecting a model. Most units operate at a 24V thermostat hookup for straightforward integration.

Combustion Research Corporation provides a 10-year limited warranty on radiant tubes for internally created corrosion and a 3-year warranty on ignition controls and electrical components on select product lines. The Synergy series carries a 1-year limited manufacturer warranty. All systems are 100% factory tested before shipment to ensure reliable performance from day one.
