2. Thermosiphon - Wikipedia

   en.wikipedia.org/wiki/Thermosiphon

   Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used) 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 ...

3. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   The tested SWH system had about 20% of the impact of an electrical water heater and half that of a gas water heater. [50] Analysing their lower impact retrofit freeze-tolerant solar water heating system, Allen et al. (qv) reported a production CO 2 impact of 337 kg, which is around half the environmental impact reported in the Ardente et al ...

4. Barra system - Wikipedia

   en.wikipedia.org/wiki/Barra_system

   Barra system. The Barra system is a passive solar building technology developed by Horazio Barra in Italy. It uses a collector wall to capture solar radiation in the form of heat. It also uses the thermosiphon effect to distribute the warmed air through channels incorporated into the reinforced concrete floors, warming the floors and hence the ...

5. 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 ...

6. Renewable thermal energy - Wikipedia

   en.wikipedia.org/wiki/Renewable_thermal_energy

   1800s. Renewable thermal energy is the technology of gathering thermal energy from a renewable energy source for immediate use or for storage in a thermal battery for later use. The most popular form of renewable thermal energy is the sun and the solar energy is harvested by solar collectors to heat water, buildings, pools and various processes.

7. 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.
