BBF,

If you want to do this technique (above, last post), then ground heating will work. But for the majority of sites, a long vertical bore hole will encounter ground water and that literally washes away the heat as that flow migrates.

Sub-surface heat trapping does work as the prior article attests, but only under very specific conditions.

Heat storage will work well in vertically drilled rock (but have you priced the cost of drilling a 250 foot bore hole in rock?).
