2. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   Even though the HTF contains glycol to prevent freezing, it circulates hot water from the storage tank into the collectors at low temperatures (e.g. below 40 °F (4 °C)), causing substantial heat loss. A drainback system is an active indirect system where the HTF (usually pure water) circulates through the collector, driven by a pump. The ...

3. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   Unglazed solar hot water systems should be installed to "drainback" to a storage tank whenever solar radiation is insufficient. There are no thermal shock concerns with unglazed systems. Commonly used in swimming pool heating since solar energy's early beginnings, unglazed solar collectors heat swimming pool water directly without the need for ...

4. Storage water heater - Wikipedia

   en.wikipedia.org/wiki/Storage_water_heater

   Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.

5. Solar thermal energy - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_energy

   The sun’s free energy can also be used to heat water to fulfil domestic hot water demands, such as the hot water that comes out of taps. Solar thermal water heating systems can provide approximately 50% of a property’s annual hot water demand (depending on the size of the property, its location etc) which in turn can help homeowners make ...

6. Thermal energy storage - Wikipedia

   en.wikipedia.org/wiki/Thermal_energy_storage

   A steam accumulator consists of an insulated steel pressure tank containing hot water and steam under pressure. As a heat storage device, it is used to mediate heat production by a variable or steady source from a variable demand for heat. Steam accumulators may take on a significance for energy storage in solar thermal energy projects.
