    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. Space heater - Wikipedia

    en.wikipedia.org/wiki/Space_heater

    Electric infrared space heater. A space heater is a device used to heat a single, small- to medium-sized area. [1] This type of heater can be contrasted with central heating, which distributes heat to multiple areas.

  4. Far infrared - Wikipedia

    en.wikipedia.org/wiki/Far_infrared

    Far infrared (FIR) or long wave refers to a specific range within the infrared spectrum of electromagnetic radiation. It encompasses radiation with wavelengths ranging from 15 μm (micrometers) to 1 mm, which corresponds to a frequency range of approximately 20 THz to 300 GHz. This places far infrared radiation within the CIE IR-B and IR-C ...

  5. 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.

  6. Catalytic heater - Wikipedia

    en.wikipedia.org/wiki/Catalytic_heater

    It can also be used to heat a stream of gas that is used for measurement or instrumentation. Space heating is a good substitution when heat is required but traditional means, such as electricity or safety concerns over explosive gas, cannot be used. Catalytic space heaters generate infrared heat to raise the temperature in a given area. [2]
