Insulated flexible bladder solar collector
A solar collector is described for heating water comprising: (a) a housing having a floor, connected to contiguous upwardly extending opposing sidewalls and endwalls and a removable transparent lid adapted to fit about the sidewalls and endwalls, the lid containing an aperture through which a valve stem can be inserted, the floor being covered with a dark radiation absorbing material, the floor further containing an aperture through which a water line can be inserted, (b) a non-opaque soft flexible plastic bladder contained in the housing the bladder having an inlet line for filling the bladder with water and an outlet line in the lower portion thereof for removing water therefrom, the outlet line in the bladder extending through the aperture in the floor of the housing, the bladder also containing an upwardly extending valve stem in the upper portion thereof extending through the aperture in the transparent lid, the valve stem containing a valve which allows air in the bladder to escape, prevents air from entering the bladder and prevents water from overflowing the bladder when filled with water, and (c) wherein at least one of the transparent lid or the upper portion of the bladder contains ultraviolet light absorbing properties to inhibit the transmission of ultraviolet solar rays therethrough.
