Hi, I have been reading this thread, anxious
to learn more....though I don't know if DIY will work
for me. I have far too many projects.

One is adding a 2.5 story addition to my house.
(And it looks like a lot of it will be during the winter. )-:

I am in Northern NJ, have a small lot - 5000 SF,
and I need to provide heat/cool for a 1200 SF addition
or possibly for the whole 3600 SF house.
I was thinking, I'll be digging up the back yard,
maybe I could have them bury a pipe for me.
But how deep?

My first-choice contractor doesn't want to go
slow for me, but he did quote me the savings
of him not putting in a furnace/boiler.
He proposes a hot water system, which seems
OK to me. I might be able to DIY a heat pump
to use for the hot water in the milder seasons.

Has anyone succeeded in something so big?

I'm waiting (2 weeks) for an estimate from
one guy who wants to do 2-3 bore holes in
the driveway. I just printed a list of 50 IGHSPA
members, sorted by zip near my house.
Will talk to some of them or ask my contractor
if he knows them.

Thanks
Seth

Hello and welcome to the site Seth. I'm sure a larger building has been done before. If you browse through AC Hackers thread (I know you have), you can see the work that another member was doing for a commercial building (I think). You basically just need to scale the gshp to the building and its heat loss.

pachai,

Daox is correct, but I must add that many people don't realize that the buried pipe (AKA: loop-field) must be scaled (to a minimum size) as well as the electro-mechanical heat-pump.
