ABSTRACT:
An apparatus for collecting solar energy wherein a heat exchange array of plastic or the like is protected against damage by excessive heat buildup. The array is housed in a normally closed chamber having a portion transparent to solar rays and the chamber is periodically vented by means responsive to heat expansion of the enclosed array. The invention permits substantial cost reductions in solar heat exchanges; particularly of the type adapted to heat buildings, swimming pools and domestic water systems.
