Pool Solar Panel Water Valve
I heat my pool with solar heat but I have not been able to justify investing a considerable sum in automating the turning on (and off) of the solar panle loop. The automatic valves and controllers that I have seen appear to cost $hundreds, thus destroying the economics of the situation. Does anyone have a source of a cheap (but effective solar water valve controller?
I did order the parts to build a valve controller (although I have still not built it) but I still need a source for a motorized valve. I am thinking that it would be cheaper and easier if the valve were closed by a spring and opened to the solar panel on position by my controller. In any case, anyone have ideas or sources?
