Solar Heating Basics

These solar collectors are part of the solar domestic hot water system. View a slide show on solar heating.

Solar heat can be used for solar water heating, solar space heating in buildings, and solar pool heaters.

Solar water heaters and solar space heaters are constructed of solar collectors, and all systems have some kind of storage, except solar pool heaters and some industrial systems that use energy "immediately." The systems collect the sun's energy to heat air or a fluid. The air or fluid then transfers solar heat directly to a building, water, or pool. Learn more about:
