Interesting. Well, I hope it works out for you. Even if the soil around the pipes get cold,
they might not get much lower than freezing. At 32F, your system should work very well.
With a 25 SEER, it's got to be a real performer.

I'd been considering using two small wells with an open-loop water to air setup.
The water-to-air exchanger would sit right behind the air intake.

But, now.. I'm starting to think that just going to solar PV to power the Sanyo
during daylight hours might be the best place to invest my money and efforts.

Now this sounds like a righteous project!

Yeah, the more I think about it, the more I think extending the operational temperature
range of the Sanyo isn't what I should be trying to do..

I can see where a water-to-air input coil would really help with cooling,
during the really hot days.. But not so much during extremely cold weather.
Or maybe it would work, if it was really sophisticated.

We just don't have enough extreme weather to warrant a big investment, both in time and money.
And, there is some question to know successful the range booster would be..

However, there is little question about PV. With a small investment,
I believe that it can be made to work in this application.
(It's been done before).. Picasa Web Albums - Dave J Angelini - MyPictures
Plus, the very idea of 'free' heating or cooling on sunny days is just plain cool..
