Insulated Buried Pipegreenspun.com : LUSENET : Countryside : One Thread
I'm looking for a source for direct buried insulated pipe for an outside corn burner boiler. It's usually the supply and return pipes together surrounded by insulation and a protective cover. the whole package is flexible. Anyone know of a source?

when we installed my taylor furnace we used quest pipe threaded into the foam pipe insulation available at most hardware stores and that was threaded into a black plastic roll pipethen burried

My nearby lumber yard can get the tubing you are talking about that is for hot water boilers. (specify it is for a hot water boiler) It is flexible and uses mobile home type fittings. Get some foam pipe wrap that slips over your pipe and then run your 2 lines inside a 4" plastic field tile (non perforated). I know a man who has used this set up to heat his house for 3 years now and has no problems. Be sure to bury the line below frost line and deeper if possible. Seal the 4" to keep out moisture as this will really cut your effeciency. Good luck

Go to www.centralboiler.com. Their dealers sell a 7" OD, 2.5" ID medium-density foam, pipe insulator sleeve. I bought 200' feet of it for my outdoor woodburner. It's about $3/foot.

BERT....YOU CAN ALSO BUILD A ROUGH BOX MADE OUT OF STYROFOAM OVER IT. SURROUND THE PIPE WITH A WASHED STONE GRAVEL FOR BETTER DRAINAGE. PLUS THROW SOME FILTER FABRIC OVER IT.SO THE MUD AND DIRT DON`T ENCASE IT.MUD EXPANDS MORE THAN ROCK. AN OLD TIMERS TRICK WAS TO THROW SOME SLAB WOOD OVER THE PIPE.THE WOOD WOULD DRAW THE FROST AWAY FROM THE PIPE.SLAB WOOD IS CHEAP TO USE AND ALSO HELPS YOU LATER TO LOCATE THE PIPE IF YOU HAVE TO DIG THE PIPE UP FOR REPAIRS. ALSO YOU CAN USE AN ETHELYNE GLYCOL IN THE PIPES FOR IN FLOOR HEATING.THUS IF YOU ENCOUNTER A POWER FAILURE OR OTHER EMMERGENCY YOUR LINES WILL NEVER FREEZE.

good answers above - only quibble, studies done at the University of Minnesota show that the temperature a eight (8) inches down never went below 30 degree fareheit. Since frostfree depth here is 4 feet the additional 40 inches of digging really isn't cost effective.
