Radiant Heating Units

Topic Summary

There are many types of devices that fit into the classification of radiant heating devices. For example, gas fired infrared heaters are used in warehouses where the roof height can be 40' above the finished floor. Gas fired infrared heaters work well at this height because they are not heating the air in the space, but rather objects within the space and the surfaces of walls and floors. Small, self-contained spaces (e.g., toll booths) may utilize portable infrared heaters.

2x2 and 2x4 infrared panels are manufactured to fit into a ceiling grid. These panels look identical to ceiling tiles. Sometimes they are used in entrances or other localized areas which are subject to cold. Other applications include workshops, greenhouses, garages and showrooms, transportation waiting areas and aircraft hangars, atrium's, animal confinement buildings, and pump stations. A cutting edge application for home heating is in-floor infrared heating, sometimes called warm floor heating. In this type of application, energy savings can be realized because the thermostat can be turned down as much as 10 degrees without sacrificing the feeling of comfort.

The sun is the main contributor of radiated heat. Solar heat gain is heat that is gained as a direct result of solar (light) rays impacting a surface which then absorbs the rays. The more rays that are absorbed by an item, the hotter it becomes; some materials can store and radiate large amounts of heat. This is the principle that underlies passive solar heating.
