2. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   A heat exchange fluid protects against freeze damage down to a locally determined risk temperature that depends on the proportion of propylene glycol in the mixture. The use of glycol lowers the water's heat carrying capacity marginally, while the addition of an extra heat exchanger may lower system performance at low light levels. [citation ...

3. Ground source heat pump - Wikipedia

   en.wikipedia.org/wiki/Ground_source_heat_pump

   A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.

4. Passive solar building design - Wikipedia

   en.wikipedia.org/wiki/Passive_solar_building_design

   The sun doesn't shine all the time. Heat storage, or thermal mass, keeps the building warm when the sun can't heat it. In diurnal solar houses, the storage is designed for one or a few days. The usual method is a custom-constructed thermal mass. This includes a Trombe wall, a ventilated concrete floor, [23] a cistern, water wall or roof pond. [24]

5. Reflective surfaces (climate engineering) - Wikipedia

   en.wikipedia.org/wiki/Reflective_surfaces...

   The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

6. Flat roof - Wikipedia

   en.wikipedia.org/wiki/Flat_roof

   A small Butynol roof installation on a residential flat roof in New Zealand. Butynol roofing is a type of roofing material made from synthetic rubber, specifically butyl rubber. It is widely used in New Zealand and other parts of the world for flat and low-slope roofs due to its exceptional durability, flexibility, and waterproofing capabilities.

7. Solar water heating - Wikipedia

   en.wikipedia.org/wiki/Solar_water_heating

   A differential controller senses temperature differences between water leaving the solar collector and the water in the storage tank near the heat exchanger. The controller starts the pump when the water in the collector is sufficiently about 8–10 °C warmer than the water in the tank, and stops it when the temperature difference reaches 3 ...

8. Water heating - Wikipedia

   en.wikipedia.org/wiki/Water_heating

   Fluid from water storage tank to external (passive) heat source; passive heat source can be the ground (soil or groundwater), sun or air via heat pump, district heating or thermodynamic solar panel; Fluid from heat pump, or thermodynamic solar panel to water storage tank; Pump, actuator, controller and other parts; Water heater; Water storage tank

9. Solar heat collector and radiator for building roof - Wikipedia

   en.wikipedia.org/wiki/Solar_heat_collector_and...

   A solar heat collector, or solar thermal collector, is used today to capture solar radiation through electromagnetic radiation with the use of solar hot water panels, solar parabolic troughs, or solar towers. Today many people create their own DIY solar heat collectors, but the inventor William Goettl was the first to design and patent this ...
