Solar energy accumulator for showers - has conical or hemispherical shape for storing maximum heat

摘要

The storage tank (5) of the shower unit which is supported by supports is conical or semi-spherical and is surrounded in known way by a ray-permeable cover (6) at a distance of about 3 to 7 cm. The sleeve surface of the tank is preferably black to retain the solar warmth and is inclined 20 deg. to 40 deg. to the horizontal. A valve is preferably provided to control the flow of water wherein the cold water flows through the valve in a first control position to the flow-in opening in the base of the tank and then into the downpipe. The hot water can now be prepared by solar energy.
