Hey -

I've completed my purchase of a pool!! Woohoo. Not sure what's more work, digging out or paying off

Anyway, I'm looking at constructing my own solar heater. There are various methods, and one of them is to take black poly-pipe and make it into a circle.

The question is, I've seen varying sizes of the pipe, 3/8", 1/2", 3/4", 1".

I'm guessing the debate is between what gets you better heat: high volume, low pressure or low volume high pressure.

My guess is high volume (ie a 1" pipe) because making x/gallons per/min at 5C is better then x-10 gallons per/min at 15C.

Anyone have any feedback?

Brad
