2. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   When a solar water heating and hot-water central heating system are used together, solar heat will either be concentrated in a pre-heating tank that feeds into the tank heated by the central heating, or the solar heat exchanger will replace the lower heating element and the upper element will remain to provide for supplemental heat. However ...

3. Central solar heating - Wikipedia

   en.wikipedia.org/wiki/Central_solar_heating

   Central solar heating is a sub-class of 'large-scale solar heating' systems - a term applied to systems with solar collector areas greater than 500 m 2. Aquifers, boreholes and artificial ponds (costing €30/m 3 ) are used as heat storage (up to 90% efficient) in some central solar heating plants, which later extract the heat (similar to ...

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-assisted heat pump - Wikipedia

   en.wikipedia.org/wiki/Solar-assisted_heat_pump

   A solar-assisted heat pump (SAHP) is a machine that combines a heat pump and thermal solar panels and/or PV solar panels in a single integrated system. [1] Typically these two technologies are used separately (or only placing them in parallel) to produce hot water . [ 2 ]
