Abstract
A solar liquid heating system having a collector receiving solar energy and heating a liquid. A liquid transfer pump moves the heated liquid to a heat transfer tank which heats water. The collector has a plate assembly mounted on a frame. Heat insulated bottoms, sides, and ends surrounded by the frame form an elongated chamber accommodating the plate assembly. The plate assembly has a plurality of side-by-side longitudinal plates. Adjacent plates have generally C-shaped sections that are located about a longitudinal tube for carrying liquid. Adjacent plates have lip and hook inter-connecting structures that cooperate with each other to clamp the tube between the C-shaped sections of the plates. The opposite ends of the tubes are connected to transverse tubular headers. The headers project through resilient grommets mounted on the sides of the frame. The top sides of the plate assembly are coated with black solar energy absorbing material. A light transparent cover encloses the plate assembly within the chamber of the collector.
