  2. Humidifier - Wikipedia

    en.wikipedia.org/wiki/Humidifier

    Steam humidifiers, or warm mist humidifiers, are equipped with a heating element. A medicated inhalant can also be added to the steam vapor to help reduce cough. Vaporizers may be healthier than cool mist types of humidifiers because steam is less likely to convey mineral impurities or microorganisms from the standing water in the reservoir. [16]

  3. Air preheater - Wikipedia

    en.wikipedia.org/wiki/Air_preheater

    The heating plate elements in this type of regenerative air preheater are also installed in a casing, but the heating plate elements are stationary rather than rotating. Instead the air ducts in the preheater are rotated so as to alternatively expose sections of the heating plate elements to the upflowing cool air. [1] [2] [3]

  4. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    A steam heating system takes advantage of the high latent heat which is given off when steam condenses to liquid water. In a steam heating system, each room is equipped with a radiator which is connected to a source of low-pressure steam (a boiler). Steam entering the radiator condenses and gives up its latent heat, returning to liquid water.

  5. Annual fuel utilization efficiency - Wikipedia

    en.wikipedia.org/wiki/Annual_fuel_utilization...

    The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...

  6. Heating system - Wikipedia

    en.wikipedia.org/wiki/Heating_system

    Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. [1] [2] Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters ...

  7. Boiler - Wikipedia

    en.wikipedia.org/wiki/Boiler

    In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas.In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used.

  8. Gas heater - Wikipedia

    en.wikipedia.org/wiki/Gas_heater

    A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or non-flued, or vented and unvented .

  9. Oil burner - Wikipedia

    en.wikipedia.org/wiki/Oil_burner

    It is dyed red to show that it is road-tax exempt. In most markets of the United States, heating oil is the same specification of fuel as on-road un-dyed diesel. An oil burner is a part attached to an oil furnace, water heater, or boiler. [1] It provides the ignition of heating oil/biodiesel fuel used to heat either air or water via a heat ...
