Big Green: Geothermal vs geoexchange

Mon Oct 27 10:13:03 EDT 2008

thanks, I like geo-exchange, it's zippy, and actually more accurate 
since it indicates the cooling as much as the heating.
Not that there is much chance of changing the incorrect American 
usage, as usual.
Of course the real challenge is to accurately size the most 
sustainable system for each application, I realize that.
