AC_Hacker & group,
After looking through my current, then past(archived) bookmarks I cannot put my <p> finger on the exact article/website so I started Google research and in roughly 1/2 hour I <p>had definative info. Seems this technology is called: Passive Annual Heat Storage or PAHS <p>acronym. A lot of the structures employing this technology are themselves either <p>extensively bermed structures or undergound homes. Not to say that improvements can't <p>be gained in above ground structures(like the tech I described in my first posting.) The only<p> things that can be done on a strict budget like you've set for yourself you are already doing <p>i.e.[LIST][*]limiting your GSHP project to one room,<p>[*]drilling due to limited geo-space,<p>[*]DIY heat pumping,<p>[*]Increasing insulation to effected room?<p>
[/LIST]Just Google search on "Passive Annual Heat Storage" and you will come up with a<p> "plethera" of answers. Here's a couple:<p>

On the earthshelters website a name & book is mentioned that comes up a lot with this type<p> tech: John Hait. He pretty much seems to be the father of this tech dating back to the early <p>80s! That was also a period when underground homes were the rage!:thumbup:
