An infrared heater or heat lamp is a heating appliance containing a high-temperature emitter that transfers energy to a cooler object through electromagnetic radiation. Depending on the temperature of the emitter, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm.Infrared heaters work by converting electricity into radiant heat. Infrared is part of the electromagnetic spectrum. The heat is the same feeling of warmth as the winter sun on your face and the heat from a coal fire.we will say that infrared (IR) heaters used indoors or outdoors are safe, especially if the appropriate safety factors are considered. In the case of IR heaters, these safety precautions include protecting yourself from possible burns and electrical safety to prevent fires.Compared to electric storage heaters or electric radiators, infrared panel heaters convert almost 100% of the electricity to heat, therefore are more energy efficient and need to operate for less time for a better output.
