I'm building a house right now myself, and would like to put solar hot water
panels on the roof in the future. Right now I would like to run lines from
the boiler room to the attic for future use. Can I use 3/4' Oxy Pex for
this purpose?
TIA

By oxy, I hope you mean O2 barrier. Just watch for long term UV
exposure. Other than that PEX is very tough. You may not want it to
freeze with water in it though.

Yup O2 barrier. I would use covert to copper through the roof. My system
uses 50%/50% glycol/water.
Thx

Are you going to be within the PEX temp/pressure limits?

It's the copper pressure limits I would worry about.
