Cpvc for hot water, I believe the pipes the pipes will never calcify
and will not radiate heat as fast as copper. You need more supports as
there is more flex. For less heat loss use Cpvc and closed cell foam
insulation, get the type of foam with pre glued seams you just pull of
the plastic and push together.

I looked at the pre glue insulation - there is some that is pretty rigid
- and then stuff that looks soft and rubbery. Which one is closed foam
insulation?
