Decided to begin a new thread on this subject.

To confuse matters more, I just read about another form of Geothermal called DX (Direct eXchange), which utilizes a refrigerant rather than water or an antifreeze solution. It also uses rather narrow copper tubing rather than heavier plastic piping.

This is a newer technology and is being touted as cheaper to install and 20-25% more efficient than water based systems.

Here are the URLs for the three manufacturers I found:
