In Las Vegas, the coils get sun all day. Just threw it together knowing I'd need more coils in the future. I ran 3/4" poly 30' from the return to the pool to the 4 - 1/2" coils (800'?). Hooked the coils up in series I think it's called, mistake.
Also I think 3/4 from the pump is too small, I get almost no flow with all 4 coils. With 3 maybe 1.5 gal a minute (13,000 gal pool).
I know I'll need more coils, maybe add enough 3/4 pipe to cover 2 more sheets of plywood.
Should I run 1.5" pipe from the pump? Does the larger diamater give more pressure along with volume?
I'll make a manifold, read about the proper method in other posts.
All replies appreciated, positive or negative!

Hi Trsix and welcome

I would run in 1.5" from the pump and take a connection off it for every panel, doing the same for the return
Running all the water through the panels just creates more resistance and slows down the flow, in effect you are only getting a 1/2" supply albiet the water may be hotter

Re: Solar pool heater fail (so far)
Thx Dennis. Still using the 3/4 supply but made temp manifold and plenty of flow through 4 200' coils. Will run 1.5" when I add more coils or panels soon.
