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.
Radiant space heaters transfer heat to directly to bodies in front of them using thermal radiation. Thermal radiation is a process by which objects at a high temperature emit heat in the form of electromagnetic waves. These heaters are often designed such that the frequency of the emitted waves are in the infrared part of the electromagnetic ...
Infrared heating uses infrared lamps, commonly called heat lamps, to transmit infrared radiation to the body that is being heated. When a body with a large surface area needs to be heated, an array of infrared lamps is often used. The lamp commonly contains an incandescent bulb that produces infrared radiation.
A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [ 1 ] [ 2 ] [ failed verification ] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters .
Infrared radiation is popularly known as "heat radiation", [31] but light and electromagnetic waves of any frequency will heat surfaces that absorb them. Infrared light from the Sun accounts for 49% [32] of the heating of Earth, with the rest being caused by visible light that is absorbed then re-radiated at longer wavelengths. Visible light or ...
The catalytic heater is contained within the package which is usually made out of stainless steel. Instrument gas and pilot preheating regulators are only used for freeze protection, and to heat up the gas before it reaches the pilot. It can also be used to heat a stream of gas that is used for measurement or instrumentation. Space heating is a ...
