Infrared heats people, floors, walls, and other surfaces directly without heating the air first. The result is an instant warming effect, similar to the effect felt when the sun emerges from the clouds on a chilly day. When infrared radiant heaters are used in an enclosed building, objects in the space absorb the emitted infrared energy. Once absorbed, the energy is converted into heat which in turn warms the surrounding air.
This method of heating, as opposed to filling a room with warm air (such as a forced air unit) allows the source of heat to begin at the floor level, not the ceiling, and makes it the most efficient and effective method in which to heat under the diverse conditions present in warehouses, storerooms and even the most immense structures imaginable.
