Gas-fired infrared heaters
There are two basic types of infrared radiant heaters.
Luminous of High Intensity
Radiant Tube Heaters
Radiant tube gas-fired heaters used for industrial and commercial building space heating use combustion of a fuel gas such as natural gas or propane to heat a steel or ceramic tube. Radiant energy from the tube strikes floors and other objects in the area, warming them. The advantage of this form of heating is maintained warmth even when a large volume of cold air is suddenly introduced, such as in maintenance garages for vehicles. The infrared heating elements also conduct heat to the surrounding air, which can be lost heat if no mechanism exists for redirecting warmed air down to the floor level.
Gas-fired radiant heaters are sometimes used outdoors to improve the comfort of people at outdoor events or on patios.
