Solar Thermal Heating Systems

Equipment that collects heat from sunlight and puts it to everyday use, most often in roof or ground collectors that warm water for homes, farms and businesses, with a storage tank and a circulating pump or natural convection carrying the heat to where it is used. An invention belongs here when the cited article describes it as a device that gathers solar heat for heating water or air. Devices that turn sunlight directly into electricity belong with electrical engineering, and fuel burning heaters belong with mechanical engineering.
