One can buy insulated line sets for direct burial from most of the outdoor
furnace retailers.

Nik,
        We cover our insulated copper pipes with the 4" plastic corrugated
drain pipe available at Low's or Home Depot. After the pipe's are insulated
we run this drain pipe from one end to the other. It takes two people, we
try to avoid using 90 degree fittings instead two 45's or use flex copper.
Its hard to get the drain pipe around a 90 degree elbow.

Esteemed Wrenches,

What is your preferred method for running thermal lines underground? We are
about to start a sizable ground-mount system and want to make sure we do
this right. (I've already seen it done the wrong way, the dirty way, and the
hard way.)

Thanks in advance for any feedback.

Best,
Nik
