The Original Heat Source!
The original heat source is the Sun. Our energy comes from the sun which provides the heat and all other energy frequencies such as light, radio, xray and gamma rays includung UV. Infrared is an energy source which provides heat. The sun emits the infrared frequency, we have reproduced this frequency for indoor use.
What is Infrared?
Before we can explain “Infrared” we must first understand that there are three basic means of transferring “heat energy”; Conduction, Convection and Infrared radiant.
With conduction, “matter” or material is used as the transport medium. For instance the cooking pan: The bottom of the pan is heated by a gas flame, or electric element, and the heat is then conducted to the inside of the pan. The heat will always travel from the hottest area (the bottom of the pan) to the coldest area (in this case the food in the pan) until both are equal in temperature.
Infrared Heating (IR) requires no medium to transport warmth. When the invisible (infrared) light collides with (or is absorbed by) surfaces, including the human body, warmth is generated. This is also known as “direct” heating or the same sort of heating we experience through the sun.
The primary advantage of Infrared-energy over any other means of heating is that the Infrared warmth can be stored in objects. A good example is the sun. After it has been shining on a brick wall, this wall still generates warmth even after the sun has gone down (in summer this may be for many hours).
It should be noted that besides infrared, the sun’s rays contain light in various wavelengths, or “bands”; some are designed to help the plants and trees, others are used to generate photo voltaic solar energy, and infrared is used to heat the earth’s surface and objects on it.
