  2. Solar water heating - Wikipedia

    en.wikipedia.org/wiki/Solar_water_heating

    Below is a table that gives a rough indication of the specifications and energy that could be expected from a solar water heating system involving some 2 m 2 of absorber area of the collector, demonstrating two evacuated tube and three flat plate solar water heating systems. Certification information or figures calculated from those data are used.

  3. Solar thermal collector - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_collector

    A solar thermal collector collects heat by absorbing sunlight. The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non- water heating devices such as solar cookers or solar air heaters. [ 1]

  4. Solar thermal energy - Wikipedia

    en.wikipedia.org/wiki/Solar_thermal_energy

    Solar thermal energy. Roof-mounted close-coupled thermosiphon solar water heater. The first three units of Solnova in the foreground, with the two towers of the PS10 and PS20 solar power stations in the background. Solar thermal energy ( STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in ...

  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. Air source heat pump - Wikipedia

    en.wikipedia.org/wiki/Air_source_heat_pump

    An air source heat pump transfers some of this from one place to another, for example between the outside and inside of a building. An air-to air system can be designed to transfer heat in either direction, to heat or cool the interior of the building in winter and summer respectively. Internal ducting may be used to distribute the air. [ 7]

  7. Cogeneration - Wikipedia

    en.wikipedia.org/wiki/Cogeneration

    Cogeneration or combined heat and power ( CHP) is the use of a heat engine [ 1] or power station to generate electricity and useful heat at the same time. Cogeneration is a more efficient use of fuel or heat, because otherwise- wasted heat from electricity generation is put to some productive use. Combined heat and power (CHP) plants recover ...
