Hi Kurt,
I think that you will find an overwhelming consensus to not use any kind of
plastic tubing for SDHW.  There will be a situation sooner or later where
you will get live steam in the loop as hot as 350 F.

> Has anyone tried Rehau Insulpex for SHW?  PEX tubing surrounded by
polyurethane insulation and covered with an LDPE jacket.  They make it in
larger diameters that are looking like a possible solution for a commercial
project.
