That's a very simple system, Guess it just goes to show how little you need to harness the sun. I live on the west coast of Canada I wish we had weather like you have. With my eight foot sq. box I'm hopping to get over 500 ft. of one inch poly pipe inside" I would like to see 700 ft". Plus with the box being covered with glass I think that should bring up the overall efficiency of the system. Also I'm starting to rethink my plan to use a separate pump; I may try hooking it up to the main filter system. BTW my wife is from S.C.

You want to use about 600 feet of pipe. Don't put all you pipe in one continous length. it would be better to devide that into 3 lengths of 200 feet in parallel, or even 6 lengths of 100 feet. This will greatly reduce the bacpressure that the pump will see and increase the dwell time inside of the pipe where the water is inside of the heater.

Here are some tables that will help you predict the Back Head Pressure that will be added to the pump you use.
