  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. Radiant heating and cooling - Wikipedia

    en.wikipedia.org/wiki/Radiant_heating_and_cooling

    Radiant systems, encompassing both heating and cooling, transfer heat or coolness directly through surfaces, such as floors, ceilings, or walls, instead of relying on forced-air systems. These systems are broadly categorized into three types: [ 19 ] thermally activated building systems (TABS), [ 20 ] embedded surface systems, and radiant ...

  4. Space heater - Wikipedia

    en.wikipedia.org/wiki/Space_heater

    Oil heaters transfer heat by convection and radiation. [4] They can silently heat larger rooms, but take longer to heat up. Like infrared models, they lack a fan, but circulate heat according to a room's air patterns, which is why it may take longer for a user to discern a difference in temperature.

  5. Ceramic heater - Wikipedia

    en.wikipedia.org/wiki/Ceramic_heater

    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.

  6. 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.

  7. Electric heating - Wikipedia

    en.wikipedia.org/wiki/Electric_heating

    Waste heat from fluorescent lamps is captured in the return air of the heating system; in large buildings a substantial part of the annual heating energy is supplied by the lighting system. However, this waste heat becomes a liability when using air conditioning. Such expenses can be avoided by integrating an energy efficient lighting system ...
