Infrared Heaters: Complete Guide for Facilities

Infrared heaters can be very efficient because they heat people, floors, equipment, and surfaces directly instead of heating large volumes of air first. Electric infrared units use electricity based on wattage and runtime, while gas-fired systems often have lower operating costs in large commercial spaces. Combustion Research Corporation typically recommends evaluating gas-fired radiant tube systems where natural gas or propane is available.

Infrared describes the heating method, while electric describes the fuel source. Electric infrared heaters are useful where gas piping is impractical, especially protected outdoor or semi-outdoor commercial areas. For warehouses, hangars, service bays, and manufacturing plants, gas-fired infrared tube or ceramic systems usually provide lower operating cost, higher BTU output, and stronger performance in high-bay spaces.

Infrared heaters are widely used for occupant comfort because they warm surfaces directly without relying on air movement. In commercial settings, this can reduce dust circulation compared with forced-air systems. Proper design is important: heaters must be installed with correct clearances, mounting heights, ventilation, and code compliance. Combustion Research Corporation systems are CSA certified for applicable ANSI/CGA standards.

Low-intensity radiant tube heaters, such as Reflect-O-Ray, Omega II, and Serengeti-IR, distribute heat over larger areas and are commonly used in warehouses, hangars, service bays, natatoriums, and industrial buildings. High-intensity ceramic heaters, such as Synergy, reach maximum temperature in under one minute and are best suited for spot heating, loading docks, work cells, and protected outdoor areas.

Infrared heater sizing depends on square footage, insulation, ceiling height, door cycle frequency, fuel type, and the target comfort zone. As a general engineering reference, warehouses may require 25–40 BTU per square foot in insulated low-bay spaces, 40–65 BTU per square foot in high-bay areas, and higher densities for leaky or frequently opened buildings.

Commercial infrared heaters are quoted by project because pricing depends on BTU sizing, building layout, fuel source, venting requirements, controls, construction material, and installation complexity. Combustion Research Corporation products are available through a North American representative network. Facility managers can request guidance through a local representative or call customer service at 888-852-3611.

Infrared heaters often outperform forced-air systems in high-bay or door-cycling facilities because they deposit heat into floors, vehicles, tools, inventory, and people rather than warming air that rises or escapes. Combustion Research Corporation documents 30–50% energy savings over conventional forced-air heating in comparable commercial applications, with faster comfort recovery after overhead doors close.

Warranty coverage varies by product family. Combustion Research Corporation lists a 10-year radiant tube warranty for internally created corrosion on Reflect-O-Ray, Omega II, and Serengeti-IR systems, plus a 3-year burner control warranty. Synergy high-intensity ceramic systems carry a 1-year limited warranty. Confirm current warranty details during specification and quoting.
