  2. Expansion tank - Wikipedia

    en.wikipedia.org/wiki/Expansion_tank

    An expansion tank or expansion vessel is a small tank used to protect closed water heating systems and domestic hot water systems from excessive pressure. The tank is partially filled with air, whose compressibility cushions shock caused by water hammer [ citation needed ] and absorbs excess water pressure caused by thermal expansion .

    These tanks often use a rubber diaphragm pressurised with compressed air. The expansion tank accommodates the expanded water by further air compression and helps maintain a roughly constant pressure in the system across the expected change in fluid volume. Simple cisterns open to atmospheric pressure are also used.

  4. Boiler - Wikipedia

    en.wikipedia.org/wiki/Boiler

    A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, [1] [page needed] [2] [page needed] including water heating, central heating, boiler-based power generation, cooking, and sanitation.

  5. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    A small tank water heater. Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating.

  6. 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.

  7. 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 ...

  8. Boiler explosion - Wikipedia

    en.wikipedia.org/wiki/Boiler_explosion

    These are boilers which are built at a factory then shipped out as a complete unit to the job site. These typically have better quality and fewer issues than boilers which are site assembled tube-by-tube. A package boiler only needs the final connections to be made (electrical, breaching, condensate lines, etc.) to complete the installation.

  9. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    At that time central heating was coming into fashion in Britain, with steam or hot air systems generally being used. Details of furnace and expansion tube from Perkins' 1838 Patent. Perkins' 1832 apparatus distributed water at 200 degrees Celsius (392 °F) through small diameter pipes at high pressure. A crucial invention to make the system ...
