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.


Thanks! That's good information

And thanks to all other for your thoughts and suggestions.
