Picking up where we left off...
It looks like they want me to put something like 400 feet of plastic pipe in the lake.
This is for a 5-6 ton unit. I want to try something different.
I can build a radiator out of hard copper pipe. I picture a 2" manifold branching into multiple 3/4 or 1/2 inch rods. I can find the thermal transfer characteristics of copper on the net, and then build it twice as big. Can't loose too much heat, right? I can silver solder it up tight so it won't leak.
Now the good part...I bet the fish would love it!
Wadda ya think?
