Regards the piping-------I know I'll sound like an idiot, but I don't have a
lot of faith in the plastic stuff. We used rubber hose, a product made by
Goodyear to Heatway's specifications for the purpose of hydronic heating.
I figure it will tolerate a little misalignment, but at this point that's a
non-issue. I'm sure the plastic would have worked equally as well, and it's
one hell of a lot cheaper to buy. We paid roughly 70¢/ft. for the 3/8"
rubber hose. While we didn't pay for a trace, they make the same product
with a trace so it can be detected easily. I felt no need because it's
placed deep enough.

Sorry to tell you this but Goodyear made some very bad hose in the
early 1990's, there E2 series. it caused Heatway to go bankrupt,
ruined 1,000's of heating systems. I had installed a few of them and
they failed. It was a disaster for the industry (and me) . There is
now a $ 200+ million class action settlement underway. Heatway was
bought by Watts, and now makes a very good all EPDM hose called Onix.
