  2. Infrared heater - Wikipedia

    en.wikipedia.org/wiki/Infrared_heater

    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.

  3. Infrared - Wikipedia

    en.wikipedia.org/wiki/Infrared

    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 ...

  4. Space heater - Wikipedia

    en.wikipedia.org/wiki/Space_heater

    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 ...

  5. Infrared lamp - Wikipedia

    en.wikipedia.org/wiki/Infrared_lamp

    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.

  6. Electric heating - Wikipedia

    en.wikipedia.org/wiki/Electric_heating

    An electric radiative space heater. Electric infrared radiant heating uses heating elements that reach a high temperature. The element is usually packaged inside a glass envelope resembling a light bulb and with a reflector to direct the energy output away from the body of the heater.

  7. Catalytic heater - Wikipedia

    en.wikipedia.org/wiki/Catalytic_heater

    Catalytic space heaters generate infrared heat to raise the temperature in a given area. [2] In addition to the larger catalytic heaters there are also small hand warmer or pocket heaters that use a catalyst combustion unit. Current units use a glass fiber substrate coated with platinum. Cheaper units may use other catalysts that don't work as ...

  8. Far infrared - Wikipedia

    en.wikipedia.org/wiki/Far_infrared

    Owing to their size and flexibility, [10] infrared panel heaters can be fitted on walls and ceilings for added-space saving benefits. Electric FIR panel heaters are shown to have up to 98.5% efficiency from supply to production of heat with satisfactory thermal comfort, thermostatic control, and with low initial investment. [11]

  9. Heating film - Wikipedia

    en.wikipedia.org/wiki/Heating_film

    A heating film, itself, is a variation of the modern ondol, but it doesn't require hot water and pipes as it is fully electric. There are also many variations of this underfloor heating system, as many underfloor heaters are based on PTC heating element, far-infrared rays, carbon film, or cables, etc. [6]
