Abstract
This disclosure generally relates to a technique and apparatus for solar heating which may be adapted for heating residential, commercial or industrial buildings, and in which the functions of solar energy collection, storage and heat-exchange are combined in the same passive structure generally consisting of a plurality of cylindrical tubes preferably fabricated of glass-fiber reinforced polyester resin which are filled with a stationary heat absorbing medium, such as water, with their surfaces preferably coated with a high absorptance material on to which solar rays are directed through a solar 'transmittor' or window, and which surfaces serve as heat-exchange elements from which heat may be extracted in a variety of ways, including passage of air and thermal siphoning, and with the tubes enclosed within an appropriate insulated chamber. Cooperative action with domestic or similar hot water systems may also be achieved.
