How Does An Infrared Heater Work

infrared heater
A source of heat-producing wavelengths, longer than visible light, which do not heat the air through which they pass, but only those objects in the line of sight.
An infrared heater is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the infrared radiation ranges from 780 nm to 1 mm.
An infrared or radiant furnace is one that uses infrared lamps, electric heating elements, flames, or radiant tubes to heat the product.  Although the heaters may also heat the furnace gasses, the primary heat source is radiant heating.  See Infrared Heaters below.
