there is also the option of PEX-AL-PEX, which is pex, covered with aluminum and then another layer of pex. Provides a complete oxygen barrier. I am using this on 180F hybrid radiant system. Some is running at 180 and some at 140.
I am currently a Colorado Master Plumber and I have been a plumber for more then 35 years. I have installed miles of PEX pipe. Like all pipe it has a number rating on it. It should have a temperature rating on it. If it has a temperature above 160 then it is OK for hot water heating.
Good point. I understand that oxygen in heating systems can cause problems with corrosion of steel pipes sections.
