2. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   When sized at 100% coverage most solar hot water systems are capable of heating a pool anywhere from as little as 4 °C for a wind-exposed pool, to as much as 10 °C for a wind-sheltered pool covered consistently with a solar pool blanket. [44] An active solar energy system analysis program may be used to optimize the solar pool heating system ...

3. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   Commonly used in swimming pool heating since solar energy's early beginnings, unglazed solar collectors heat swimming pool water directly without the need for antifreeze or heat exchangers. Hot water solar systems require heat exchangers due to contamination possibilities and in the case of unglazed collectors, the pressure difference between ...

4. Photovoltaic thermal hybrid solar collector - Wikipedia

   en.wikipedia.org/wiki/Photovoltaic_thermal...

   The average fluid temperature can be between 25 °C in swimming pool applications to 90 °C in solar cooling systems. Covered PVT collectors resemble the form and design of conventional flat plate collectors or evacuated vacuum tubes.

5. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   The Solar Bowl above the Solar Kitchen in Auroville, India concentrates sunlight on a movable receiver to produce steam for cooking. Solar cookers use sunlight for cooking, drying and pasteurization. Solar cooking offsets fuel costs, reduces demand for fuel or firewood, and improves air quality by reducing or removing a source of smoke.

6. Swimming pool - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool

   A swimming pool, swimming bath, wading pool, paddling pool, or simply pool, is a structure designed to hold water to enable swimming or other leisure activities. Pools can be built into the ground (in-ground pools) or built above ground (as a freestanding construction or as part of a building or other larger structure), and may be found as a ...
