Smells Great
No problems with my insurance company, no savings either.
Wherever the PEX enters the house, make sure you leave room for expansion. That pipe will grow a couple of feet depending on the length of your run and the temperature. Same for going to the furnace. Don't fix the pipe down too firmly as it needs room to move.
Come one over for a beer then! We'll change the set temperature and watch it grow. (Might take long enough that we won't care after that many beers of course. )I did my own install on a unit and I'm sorry but the pex growing a foot is totally false... My lines are cut off within 6" of the block and there has never been any movement. If there was any it was negligible.
I would have to see a line expand in person to believe it to be true.

I can even tell if the temperture on mine is running high (happened mostly on a moderate day when the damper wasn't fully closed) by how much the length changes. It's really apparent from summertime when the PEX is say 60 degrees in the ground to say 150 degrees with hot water in it. Absolutely no doubt there is a significant change in mine. It may be that PEX-Al or others don't expand as much.
Is your underground a homemade system?? Or was it purchased/foamed???
