My name is Mike, we built our loghome Aug-2001 thru May-2002, the move in date.
We have a close loop Geothermal system, some info here http://mmrosinski.tripod.com/loghome/id19.html.
Pict here (build picts in the link above)
For a few years I even plotted the energy usage on a graph, some find it useful to see.
My system is almost 9 years old, I'm studying where the changes have come in the past 9 years in Geothermal systems.
This forum is..neat to me, I'm a engineer by degree.
I'll be reviewing the forums for now, and possible adding my thoughts also.
