Infrared radiation is electromagnetic radiation which is generated in a hot source (even all alive objects ) by vibration and rotation of molecules. The resulting energy is controlled and directed specifically to and on people or objects. This energy is not absorbed by air, and does not create heat until it is absorbed by an object. The sun is the basic energy source. Energy is projected 93,000,000 miles through space to heat the earth by the infrared process. This infrared energy travels at the speed of light, and converts to heat upon contact with a person, a building, the ground or any other opaque object. There is, however, no ultraviolet component (sun tanning rays) or microwave (cooking rays) in infrared. 

METHODS OF HEAT TRANSFER

Radiant or infrared heating provides a unique method of achieving a desired comfort level at a specified area. To best understand infrared heating, a comparison with different methods of heat transfer should first be considered. Heat transfer can be accomplished by any one of three methods, CONDUCTION, CONVECTION or RADIANT.

CONDUCTION is placing an object in physical contact with the source of heat, such as a hot water bottle against the body.

CONVECTION heat involves using a source of heat to warm the air and create a desired temperature level around people.Traditional>  wet and dry saunas, home heating with a forced-air furnace are the examples of CONVECTION heat.

INFRARED heat uses invisible electromagnetic waves from an energy source. The perfect examples of electromagnetic infrared energy is heat from the sun or human body. In an infrared system, these energy waves are created by a heat source - ceramic heater - and directed by optically designed reflectors toward or onto the object or person. A fire place is a more familiar form of radiant (infrared) heat.
Infrared travels through space and is absorbed by people and objects in its path. Infrared is not absorbed by the air. With convection heating the air itself is warmed and circulated ... however, warm air always rises to the highest point of a building. With Infrared heating, the warmth is directed and concentrated at the object or people where it is really needed.

CLEAN
Electric infrared, like other forms of electric heating, is the cleanest method of heating. There are no by-products of combustion as with fossil fuel burning units. Electric infrared adds nothing to the air nor takes anything from it.

SAFE
UL listed
No open flame
No moving parts to malfunction
No fuel lines to leak
No toxic by-products of combustion

EFFICIENT
All electric infrared heaters convert energy to heat at 100% efficiency.
