for case study references on geothermal heat pumps go
to:http://www.ghpc.org/cases/dircases.htm#Residential Case Studies
find an application that is 5 or so years old and call the owner.

thermal energy due to high rates of circulation in a small loop ie.
changes in thermal gradient that became permanent...?
Why is building a house for oneself a whole lot different?
