  3. Thermosiphon - Wikipedia

    en.wikipedia.org/wiki/Thermosiphon

    Thermosiphon. Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces ...

  4. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    Gas water heaters have an exhaust vent or one to two exhaust pipes on the top, and still require electric power for electronics, sensing and ignition. A three-phase, 21 kW, 400-volt tankless water heater in Europe, with new European color coding for three-phase power. There are also heaters that use several single-phase circuits instead.

  5. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    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. In industry, hot water and water heated to steam have many uses. Domestically, water is traditionally heated in vessels known as water heaters ...

  6. Radiant heating and cooling - Wikipedia

    en.wikipedia.org/wiki/Radiant_heating_and_cooling

    Radiant heating and cooling. Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", [1] "embedded surface systems", [1] "thermally ...

  7. Forced-air gas - Wikipedia

    en.wikipedia.org/wiki/Forced-air_gas

    Gas-fired forced-air furnaces have a burner in the furnace fuelled by natural gas. A blower forces cold air through a heat exchanger and then through duct-work that distributes the hot air through the building. [2] Each room has an outlet from the duct system, often mounted in the floor or low on the wall – some rooms will also have an ...

  8. Reverberatory furnace - Wikipedia

    en.wikipedia.org/wiki/Reverberatory_furnace

    A reverberatory furnace is at a disadvantage from the standpoint of efficiency compared to a blast furnace due to the separation of the burning fuel and the subject material, and it is necessary to effectively utilize both reflected radiant heat and direct contact with the exhaust gases to maximize heat transfer. Historically these furnaces ...

  9. Copper in heat exchangers - Wikipedia

    en.wikipedia.org/wiki/Copper_in_heat_exchangers

    Copper heat exchangers are important in solar thermal heating and cooling systems because of copper's high thermal conductivity, resistance to atmospheric and water corrosion, sealing and joining by soldering, and mechanical strength. Copper is used both in receivers and in primary circuits (pipes and heat exchangers for water tanks) of solar ...
