In regards to the insulated pipe im installing at home now I am using a 5 wrap product from z supply.
Why? Conduction of heat, creating barriers for heat to cross vs simply laying in contact with cold wet soil.
In one scenario a guy pulled thermopex through 6 in schedule 40 and saw a 75% reduction in heat loss vs burying it direct
He sealed both ends of the pvc and placed temp sensors inside to monitor it. With no hear flowing through, his temps ran 47-48, under full load at 180, the air in his "pvc plenum" stayed around 85, creating a barrier to the cold soil. He said it lost 75 percent less heat.
Why I went with z supply is its great about heat lost but I agree that logstor has tougher casing, so I pulled there 5 inch casing through 6 in pvc, the vapor barrier of z supply is another key factor, ur foam filled products dont have that I just took it a step farther to create another dead air space or pvc plenum for my pipe to run through
This is what I planned to do when I replace my lines this summer. From the house to the boiler already has a buried 6" PVC pipe. Correct me if I'm wrong Scott, but I'm betting you slid each ten foot section over the 5" instead of trying to slide the entire length of five inch thru a already assembled six inch pipe?
I took a piece of five inch drain tile and its a snug fit inside of a 6" PVC. I just can't see being able to pull it thru 80' of already buried pipe. I was thinking of using three wrap to replace what I already had, it should be much easier to coach thru the 6". If I think I have room I was also thinking about pulling a 3/4 or 1" water line along with it so I can have a hydrant at the boiler. The new line I'm burying to the shop will have five wrap. It's not feasible to dig the old one up with the landscaping, well head, etc that wasn't there when I buried the original.
