Solar heater

Abstract

A novel method of making a solar collector is disclosed and described. The solar collector includes a base and a plurality of upstanding walls extending about the perimeter of the base. An input and an output extend through the walls to communicate with a plurality of liquid conduits integral with the base. A transparent cover is secured to the upstanding walls for covering the base and the plurality of conduits. The conduits and the base are constructed of a one-piece molding of a curable material. The invention resides in the method of forming the solar collector through a molding process. A first and a second mold element are positioned relative to one another to form a mold cavity defining the outer configuration of the solar collector. The mold cavity is completely filled with a curable material. The curable material is allowed to cure only adjacent the mold cavity wall whereafter the mold cavity is drained of the non-cured material thereby creating the internal configuration of the solar collector. The solar collector is removed from the mold cavity upon complete curing of the collector. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation of applications and is not to be construed as a limitation on the scope of the claimed subject matter.
