I have probably been on about 30 sites trying to understand what they were saying, as a mechanical/nuclear engineer it just wasn't making sense that the same 40-60degF earth could heat and cool a home. As soon as I saw the reversable A/C comment it clicked into place for me. I want to thank you guys, the comment about the reversable A/C made it all click.

Does Egg Geothermal work in Atlanta Georgia also? Are there Green tax incentives and credits related to the stimulus package in Georgia? Very informative Egg geothermal website. Hope to see them around the web more. Egg geothermal heat pumps sound green to me! Does Egg Geothermal work in Atlanta Georgia also?

I work for a great company in Florida, Egg Systems, and we have been hard at work spreading the word about geothermal heat pumps. Especially when you consider the 30% tax credit now available, state incentives, and energy savings - it's becoming a lot more affordable. Great information and thanks for sharing!

The hot coils are outside trying to dump the heat of compression. The air temperature might be 90 or 100 degrees, so the dumping of heat is not very efficient. If you could somehow submerge those hot coils in cool water rather than hot air, the AC would run a lot more efficiently. This is the basic idea behind a geothermal AC system. Cool water is pumped from a well (or the coils are buried ten feet underground where the temperature of the soil is a stable 60 degrees or so). It saves a lot of money on the AC. If you use a heat pump, you can get the same benefit for heating too. For more info see How do geothermal heat pumps work?

I actually submitted a report to the US Congress on the potential use of GSHP at NASA facilities as part of my current job. I did a similar study for the Customs and Border Protection Leadership Academy at Harpers Ferry. The biggest drawback of a GSHP system is the initial cost. So for retrofits it may take a long time to realize the savings. However if planned on early -- before construction of a facility starts, the economic advantages generally pay back in a very reasonable time. -Axt Marshall, I am getting my certification as a GSHP designer.
