What do you think of this.

As I mentioned in a previous post ,I'm planning on moving my OWB next to my wood shed.I recently purchased about 300 ft of 2 1/2 inch water line for nearly nothing.
I was considering using this as conduit and running my pex thru it.I plan to bury the 2 1/2 inch pipe about three feet deep and insult it with sand.By doing this if I ever have any line problems I can simply pull it out and slide another thru.

What is the opinion on doing this?

Personnaly I think you will end up heating the ground more than you will heating your house. I spent the extra dough and bought the logistor. In hindsight I think if I had the time I would have got 4" big O and hung the pex inside then "injected" the big-o every 6" or so with expantion foam. Just my 2cents.
