Richardson, J L

A passive solar water heater is described comprising a collector enclosure having a transparent upper surface and a curved, reflective inner surface and end walls; a storage tank within the collector enclosure positioned to be heated by the sun's rays both directly and reflected from the inner surface of the collector enclosure, and having a cylindrical wall and opposed end walls; a first pipe extending through and attached to one end wall along the longitudinal axis of the storage tank and extending to a first position, adjacent the cylindrical wall, inside the storage tank; a second pipe extending through and attached to the other end wall along the longitudinal axis of the storage tank and extending to a second position in the storage tank, adjacent the cylindrical wall; the first and second positions being generally diametrically opposed to each other; the first and second pipes extending through the end walls of the collector enclosure to support the storage tank within the collector enclosure; first releasable means to fix the relative positions of the collector enclosure and the storage tank as desired; a support frame for the heater and carrying the first and second pipes; and second releasable means on the support frame to allow variation and fixing of the angle of the collector enclosure without rotating the storage tank from its desired position.
