    Tank-style water heaters use natural gas or an electric coil to heat the water in the tank. Gas water heaters are generally less energy-efficient than electric water heaters, but the cost of ...

  3. 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 ...

    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.

    Two red paralleled hot water storage tanks connected to a wood-fuelled furnace. A hot water storage tank where one of the heat sources is solar heating A, that is sent into the hot water storage tank via a smaller pump B (circle with triangle) and the heat exchanger spiral in the hot water storage tank. The other spiral C can be used for a e.g ...

  6. Heat trap - Wikipedia

    en.wikipedia.org/wiki/Heat_trap

    The convective (micro)circulation is stopped by the loop which does not allow warm water to pass further into the pipe. Heat traps are valves or loops of pipe on the cold water inlet and hot water outlet of water heaters. The heat traps allow cold water to flow into the water heater tank, but prevent unwanted natural convection and heated water ...

  7. 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 ...

  8. Expansion tank - Wikipedia

    en.wikipedia.org/wiki/Expansion_tank

    Expansion tank in a central heating system. 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 ...

  9. Condensing boiler - Wikipedia

    en.wikipedia.org/wiki/Condensing_boiler

    Condensing boilers are water heaters typically used for heating systems that are fueled by gas or oil. When operated in the correct circumstances, a heating system can achieve high efficiency (greater than 90% on the higher heating value) by condensing water vapour found in the exhaust gases in a heat exchanger to preheat the circulating water.
