Default BTU's per dollar

How well do you think the flexible, corrugated, black plastic septic-system
pipe would work?

It's fairly thin-walled, so the heat transfer would be fairly good I would
think, and by being flexible, you could bury a bunch of coils, reducing the
amount of property that would have to be dug up.
