  2. Storage water heater - Wikipedia

    en.wikipedia.org/wiki/Storage_water_heater

    Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.

  3. Water heat recycling - Wikipedia

    en.wikipedia.org/wiki/Water_heat_recycling

    Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...

  4. Hot water storage tank - Wikipedia

    en.wikipedia.org/wiki/Hot_water_storage_tank

    A hot water storage tank (also called a hot water tank, thermal storage tank, hot water thermal storage unit, heat storage tank, hot water cylinder, and geyser) is a water tank used for storing hot water for space heating or domestic use. Water is a convenient heat storage medium because it has a high specific heat capacity. This means ...

  5. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...

  6. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    Maintaining constant shower temperature: Similarly, unlike with a tank heater, the hot water temperature from a non-modulated tankless heater is inversely proportional to the rate of the water flow—the faster the flow, the less time the water spends in the heating element being heated. Mixing hot and cold water to the "right" temperature from ...

  7. Gas holder - Wikipedia

    en.wikipedia.org/wiki/Gas_holder

    The tank was above ground and was lined with wood; the lift was guided by tripods and cables. Pulleys and weights were supplied to regulate the gas pressure. [13] Brick tanks were introduced in 1818, when a gas holder could have a capacity of 20,000 cubic feet (570 m 3). The engineer John Malam devised a tank with a central rod-and-tube guide ...
