I am having a wood boiler installed, hopefully by the end of this week. Im not doing most of the indoor installation, but I will be laying the insulated pipe from the boiler to the furnace. im having a hard time deciding on which brand to buy. I want it to hold the heat very well, but not pay out the butt for it. anybody here can help direct me to what is economical but also wont lose more than 1 degree over the 50 or so feet the water will travel?
im leaning towards the 4 wrap covered in 4inch plastic tubing filled with spray foam

just normal high temp pex with closed cell foam insulation. the thicker stuff

its going to be buried underground so i dont think that will work.
sorry i didnt mention the underground thing before
but yes the foam cell stuff would work indoors on the non insulated piping thru the house

Incase it in styrofoam and bury it, that's what we did when I helped the neighbors install theirs. We used the durofoam stuff with the green on one side and silver on the other it was quite a bit more flexible than the standard stuff. I think we went 8" wide and then made a sandwich with it and glued it togethere with a slot for the pipe. Stagger the joints so it stays together well. Put sand underneath to level and cover it with sand before you bury it to keep bigger rocks from punching into it.
