Flush Mount Heaters

Many models, including vacuum-fired and unvented ceramic burner units, require no direct venting, reducing roof penetrations and installation costs. Power-vented configurations are also available for applications needing mechanical exhaust. Your representative can help determine the correct venting approach for your building code and layout.

Most units operate on natural gas or LP/propane gas, with dual-fuel configurations offered across several product lines. Electric infrared models are also available for facilities without gas infrastructure, offering zero CO2 or NOx emissions while maintaining comparable heating performance for garages and outdoor spaces.

Yes, several models are rated for protected outdoor and semi-outdoor use, including covered patios, dealership canopies, loading docks, and event venue overhangs. These units reach full operating temperature in under one minute, making them well-suited for spaces with intermittent heat loss or open-air exposure.

BTU requirements depend on ceiling height, insulation, square footage, and desired temperature rise. Combustion Research offers models ranging from 30,000 to over 250,000 BTU input, plus custom-engineered vacuum systems scalable from 500 sqft to over a million sqft. A heat loss calculation service is available to size systems accurately.

Most radiant tube systems include a 10-year warranty on radiant tubes against internally created corrosion, plus a 3-year warranty on burner housings, ignition controls, and electrical components. High-intensity ceramic burner heaters typically carry a 1-year limited warranty from the manufacturer.

Yes, stainless steel burner housing and tubing variants are specifically engineered for high-humidity, chloramine, and road-salt exposure found in natatoriums, ice arenas, and vehicle wash bays. These corrosion-resistant configurations extend equipment life significantly compared to standard powder-coated housings in aggressive environments.
