  2. 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.

  3. Gas mantle - Wikipedia

    en.wikipedia.org/wiki/Gas_mantle

    An incandescent gas mantle, gas mantle or Welsbach mantle is a device for generating incandescent bright white light when heated by a flame. The name refers to its original heat source in gas lights which illuminated the streets of Europe and North America in the late 19th century. Mantle refers to the way it hangs like a cloak above the flame.

    The heat retaining bricks are covered in a decorative material such as brick, tiles or stone. This flue gas circulation avoids the considerable heat loss to the chimney and outside air in conventional systems. The heat from the flue gases is absorbed quickly by the bricks and then released slowly to the house rather than the chimney.

  6. Kerosene lamp - Wikipedia

    en.wikipedia.org/wiki/Kerosene_lamp

    A kerosene lamp (also known as a paraffin lamp in some countries) is a type of lighting device that uses kerosene as a fuel. Kerosene lamps have a wick or mantle as light source, protected by a glass chimney or globe; lamps may be used on a table, or hand-held lanterns may be used for portable lighting.

  7. Direct vent fireplace - Wikipedia

    en.wikipedia.org/wiki/Direct_vent_fireplace

    Direct vent fireplaces are extremely efficient compared to a traditional fireplace and can operate at about 85% efficiency. Even a very efficient traditional fireplace only operates at about 15% efficiency. This is because most of the hot air generated by the fire travels up the chimney due to convection.

  8. Gas-discharge lamp - Wikipedia

    en.wikipedia.org/wiki/Gas-discharge_lamp

    A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
