how to minimalize heating from the sun?

[dirk_brijs]

I have some PVC piping from my drain and return run along an outside wall which is exposed to the sun. As I live in Thailand that makes exposed to alot of sun.
How can I minimalize the heating of the water in those tubes to a max.
is there any insulation material available to keep things cold?
wrap in aluminum foil maybe to reflect?
any advise?
don want my chillers to get overpowered.

any advise?
there must be some members in the hotter states like Arizona or Texas facing the same problem?
how did you guys deal with it?
I know the water in the pipes is always moving so heating would be maybe not a major issue (although??) but all little bits help in reducing the bills right?

Shielding and insulation are your best bet. There are several options for pipe insulation available, but I can't speak to availability where you are. Shielding can be as simple as a strip of plywood over the pipe to block the sun. Think how much cooler you are in the shade.

Would any insulation for hot water work to keep the water cold too or ??

Absolutely. Anything that insulates that pipe from the sun.
