[AT] OT: Gas story

Thu Jul 5 14:12:31 PDT 2007

I like the geothermal heat pumps too, and plan on putting one in our new
house (couple of years away).  Probably closed loop.

Not many people around Memphis do this so I have had to hunt for
installers but I look forward to the lack of dry indoor air and thus
static in the winter and lower energy bills.  I estimate that the
additional up-front cost will be recouped over single-digit years,
getting shorter as energy costs go up.

Jerry,

We have more in common than I thought.  We both have extensive
experience
with Overhead Doors, and now I find the common experience with ground
source
heat pumps.  

If people knew more about them they'd be much more popular than they
are.
