Automatic overtemperature control system for solar water heater panels is disclosed. In response to lack of liquid circulation through a solar panel, either through loss of liquid or failure to use water heated in the panel valve means are actuated at a preselectable temperature value to introduce cooling water into the circulation system which includes the solar panel. Such system assures the integrity of circulation through the solar panel and against panel degradation due to overheating. Cooling water is added directly to the panel or through an interconnected hot water storage tank. If desired, the system may be used for direct filling the solar panel or as a back-up to conventional float valve operated fill system. The automatic overtemperature control system is applicable either to thermosiphon or pressured circulation through the solar panel to maintain its temperature below a preselected value.
In a solar water heating system including a solar collector panel, a water storage tank, a normally closed water circulating conduit means interconnecting said panel and said tank and a one-way valve for controlling the flow of water between said solar collector panel and said water storage tank, an overtemperature control system which comprises temperature responsive means mounted on said solar collector panel to sense the temperature thereof, cold water supply means, valve means in said overtemperature control system operable by said temperature responsive means for introducing cold water from said cold water supply means into said overtemperature control system and conduit means for dumping over-heated water from said closed water circulating conduit means when the temperature of water in said solar collector panel exceeds a predetermined value;
Apparatus for continuously maintaining the temperature of a closed solar water heating system below a predetermined temperature value which comprises:
