My buddy Eks just replaced his host-water furnce with a high-efficiency unit.
Can you tell that Eks is an engineer?
The plumber used one of those fancy pipe-compression tools that mashes the mating parts together with an O-ring for sealing. Faster and safer than sweating the joints together, but I want to fast-forward two or three decades to check out the durability.
As he put it, “You may be able to get a better furnace installation, but you probably can’t pay any more for it…”

YO, Ed!
So where did he get those cool, ivory pipe collars that protect the copper pipes as they pass through the floor joists?
Hrap
Beats me; IIRC plumber-man brought all the tools & materials. They look like standard plastic parts, though, so maybe you can get ’em at the LowePot’s. It’s not clear they slip around existing pipes… for new construction only?
Although our heating pipes creak & snap, much of the racket comes from copper pipe expanding over steel hangers. It seems the wonders of slippery plastic lay several decades in the future, back when This Olde House was built.
