......... what can we learn (The Residental Home-Owner) from "Case Studies"? Any suggestions & thoughts?

by "case studies" you mean......? if you want real world operating cost demonstrations their are hundreds available on WEL server links offered here regularly. If that's not what you mean, you are to cryptic for me.

There are plenty of examples of well running geo systems with considerable run time and historical detail available on line.

An example is at http://www.welserver.com/WEL0043 .

Docjenser has many using the same monitoring and instrumentation.

And many more are available at http://www.welserver.com .

Best regards,

Case study refers to the collection and presentation of detailed information about a particular participant or small group, frequently including the accounts of subjects themselves. A form of qualitative descriptive research, the case study looks intensely at an individual or small participant pool, drawing conclusions only about that participant or group and only in that specific context. Researchers do not focus on the discovery of a universal, generalizable truth, nor do they typically look for cause-effect relationships; instead, emphasis is placed on exploration and description.

*** I read part of it and since it was hard to decipher, skipped the rest. I know
you don't care, but Mike is right.

I know what a case study is and I can't direct you to a specific one. I guess my question was, what are you after.
If you are preparing a research project, then maybe you can do a case study. If you are considering geo and wish for testomonials from owners, they are available here and on other geo forums.
If you are interested in dispassionate performance data, back to the WEL server.

Keep in mind, the accumulation of anecdotes (case studies) is not data. Even studies pooling data from many installations reveal enormous differences in performance due to design flaws. Even within the same study, different sites show performance differences of more than 100%.
