Oxy barrier pex for panel radiators?

ALH_4 Member Posts: 1,790
I have seen a lot of pex run at 180F, and have seen no failures. The only temperature failure of pex I have seen was connected to the supply side of a solar panel, and that had even lasted quite a while. That was likely due to a VERY high temperature as well as a higher pressure than a typical hydronic heating system.

    oxy barrier pex for panel radiators?

    I'm a homeowner putting in panel radiators in my basement. Converting over from a 50 year old forced air furnace. Some friends said it's ok to use oxy barrier pex for the radiators. I see it's supposed to be good up to 200F, but I saw on some websites they recommend to limit it to 140F for durability and safety. I'm leaning toward copper. Planning on a Munchkin T50M. I have tried to size the rad's for a 140F max temp, but, hey, would like to have the option to go higher if needed. ....Thoughts?
