Back around 1980, I saw plans in Popular Science for a very cheap solar heater. It was, IIRC, a 100' coil of black poly pipe mounted to a black painted marine plywood box and affixed on the roof. The same black poly pipe that transports potable water from my well to my house. It was to be plumbed between the water supply and the water heater to preheat the input to the heater. No need to drain it and bypass it for the winter in Pinellas. And it sounds like Dan's already got the plumbing loop to the roof. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
