Abstract
Abstract A Solar Heater for collecting solar radiation in a fluid having a base, a flexible fluid retaining member connected adjacent the base for retaining a fluid, and for collecting the radiation of the sun, expansion limiting members connected to the base and positioned with respect to the flexible fluid retaining members for limiting the expansion of the flexible fluid collecting member, as a fluid is flowed through said flexible fluid retaining members by introducing the fluid through a flow way for flowing the fluid therein and a flow way for flowing the fluid therefrom.
