An upwardly convex spherical lens structure is supported over the boiler and comprises a closure for the area enclosed within the boundaries of the inner hemispherical wall of the boiler and the lens assembly or structure functions to direct light rays incident thereon onto the inner wall of the boiler. The solar heater additionally includes a hollow downwardly opening transparent hemispherical cover of generally the same radius of curvature as the boiler and which is secured over the lens assembly in outwardly spaced position relative thereto with the center of curvature of the cover substantially coinciding with the center of curvature of the lens assembly. Water or other liquid inlet and outlet structure is provided on a second form of the invention for admitting liquid to be heated into the interior of the boiler between the inner and outer plates theeof and for withdrawing heated liquid from within the boiler.
