  3. Heat detector - Wikipedia

    en.wikipedia.org/wiki/Heat_detector

    A residential heat detector. A heat detector is a fire alarm device designed to respond when the convected thermal energy of a fire increases the temperature of a heat sensitive element. The thermal mass and conductivity of the element regulate the rate flow of heat into the element. All heat detectors have this thermal lag. Heat detectors have ...

    en.wikipedia.org/wiki/Tankless_water_heating

    Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters — are water heaters that instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat exchanger coil unless the unit is equipped with an internal buffer tank.

  8. Rotating pocket heater - Wikipedia

    en.wikipedia.org/wiki/Rotating_pocket_heater

    A rotating pocket heater, also called pocket heater or Kinder heater, holds and rotates a substrate during vacuum deposition. [1] During rotation, the substrate is sequentially exposed to more than one environment, for example, heat, oxygen, metal vapor, etc. [2] Rotating pocket heaters has been used in reactive evaporation system to create YBa2Cu3O7 layers on planar semiconductor wafers.

  9. 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.
