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. [43] An active solar energy system analysis program may be used to optimize the solar pool heating system ...

3. Space blanket - Wikipedia

   en.wikipedia.org/wiki/Space_blanket

   A space blanket (also known as a Mylar blanket, emergency blanket, first aid blanket, safety blanket, thermal blanket, weather blanket, heat sheet, foil blanket, or shock blanket) is an especially low-weight, low-bulk blanket made of heat-reflective thin plastic sheeting. They are used on the exterior surfaces of spacecraft for thermal control ...

4. Swimming pool - Wikipedia

   en.wikipedia.org/wiki/Swimming_pool

   Use of a pool cover also can help reduce the amount of chemicals (chlorine, etc.) required by the pool. Outdoor pools gain heat from the sun, absorbing 75–85% of the solar energy striking the pool surface. Though a cover decreases the total amount of solar heat absorbed by the pool, the cover eliminates heat loss due to evaporation and ...

5. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors. Solar thermal collectors are classified by the United States Energy Information Administration as low-, medium-, or high-temperature collectors.

6. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   A solar thermal collector functions as a heat exchanger that converts solar radiation into thermal energy. [31] It differs from a conventional heat exchanger in several aspects. The solar energy flux (irradiance) incident on the Earth's surface has a variable and relatively low surface density, usually not exceeding 1100 W/m 2 without ...

7. Renewable thermal energy - Wikipedia

   en.wikipedia.org/wiki/Renewable_thermal_energy

   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.
