    en.wikipedia.org/wiki/Pool_fire

    A pool fire is a type of diffusion flame where a layer of volatile liquid fuel is evaporating and burning. The fuel layer can be either on a horizontal solid substrate [ 1 ] or floating on a higher-density liquid, usually water. [ 2 ]

  3. Pilot light - Wikipedia

    en.wikipedia.org/wiki/Pilot_light

    The appliance efficiency of a gas-fired balanced flue local space heater in pilot light mode is almost equal with the appliance efficiency measured at the reduced power of the appliance, which efficiency is between 65–95% based on the low calorific value of the consumed gas, making part of the pilot light's energy consumption into useful heat.

    He developed the first automatic storage tank gas-fired water heater, which went into production in 1889. [38] Ruud worked for George Westinghouse (1846–1914), but eventually bought the rights to produce the product he invented and formed his own company in 1897.

    These effects can largely be overcome using electronic ignition systems, where the contact breakers are retrofitted by a magnetic (Hall effect) or optical sensor device. However, because of their simplicity, and since contact breaker points gradually degrade instead of catastrophically failing, they are still used on aircraft engines.

  6. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    A hybrid water heater is a water heating system that integrates technology traits from both the tank-type water heaters and the tankless water heaters. [5] It maintains water pressure and consistent supply of hot water across multiple hot water applications, and like its tankless cousins, it is efficient and can supply a continuous flow of hot ...

  7. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    In traditional plumbing in the UK, the space-heating boiler is set up to heat a separate hot water cylinder or water heater for potable hot water. Such water heaters are often fitted with an auxiliary electrical immersion heater for use if the boiler is out of action for a time. Heat from the space-heating boiler is transferred to the water ...

  9. Piezo ignition - Wikipedia

    en.wikipedia.org/wiki/Piezo_ignition

    Piezo ignition is a type of ignition that is used in portable camping stoves, gas grills and some lighters. [1] Piezo ignition uses the principle of piezoelectricity , which is the electric charge that accumulates in some materials in response to mechanical deformation.
