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.
