Are you looking for the insulated underground pipe or just plain pex pipe?

I bought mine from andersons outdoor furnaces in wisc. They are on e-bay as:freeheat4u. "free" shipping from e-bay site, quoted on their site but $100 cheaper.

What's the underground PEX heat rating? I plan to buy a Waste Oil Boiler, and it can exit at as hi as 240f

I wouldn't want to run 240° water through the PEX of our OWB.Does the burner that you are planing to get have controls to keep the temp.at a lower setting.I would think if it didn't that I would install some kind of a limit so as to keep it from reaching temps that high.

i think i read  180 max for open systems and less for pressurized systems (i can't say for certain but i think i am very close)
you should be able to jsut ask a dealer or search on line. heck i think there are enough dealers here to quote a manufacturers warranty on the stuff.

WillieG you are right..Im using PEX-AL-PEX...so when water s 180F..Pipe can withstand a psi of 125...200F water..pipe can withstand a psi of 100...My furnace is a closed system..

I got 250' of 1-1/4" OB PEX off ebay for $375 shipped.  I forget the seller, but they were the only ones selling 1-1/4" OB PEX.

What's OB Pex?

As far as 240f,  I was just stating how hot the oil boiler can get the water, but the manufacturer sets it at 180f, I beleive. And to keep the return above 140, to avoid corrosion, there's a mixing valve to add hot outlet water to the return

OB pex = Oxegen Barrier It is pex with a special"sleeve' or coating (not reaaly sure) that prevents oxygen from penetrating from outside into your lines. If you are using a closed system with pressure this type of pipe is a MUST have as pressure systems do not work well with oxygenn in them. An open system such as most OWB can pump a little oxygen through the system and it will purge itself at the OWB

There seem to be so many varieties of piping... I'll wait until we buy the house, next week, and then the waste boiler...

even on open systems, it's recommended to use oxygen barrier pex to prevent extra oxygen into your system.  my heatmor is a semi-closed system in that it's non-pressurized and can vent to the atmosphere but it doesn't let air in.

good call paintballs i do agree with you that it is a good idea to use it with any system as another benifit from it is that the coating that prevents the oxygen from entering the pipe also makes it "slicker' and reduces friction allowing for more GPM and less head pressure on yoru system. In long runs this can be benificial to some degree
