I think you have a false impression of the way a groundwater-exchange heat pump works. You don't have to dig wells per se, you just have to bury the heat exchanger deep enough that it's in the ground water. You don't move the water to the heat pump, you move the refrigerant to the water.
Of course if the shallowest ground water is 2000 feet down . . .
...
In virtually any location it would be cheaper to dig the well... :)
There are variations from fully closed loop in ground, bury the loop in a lake, use one or two wells as source/reject water, simply put the closed lood down a well bore...
I haven't looked recently but when researching prior to installing the one I did, OSU (OK, not OH) had a very comprehensive site supporting their research. TVA did at one time as well, but I think they've sorta' finished the work they were doing...whether the site is still publicly available or not I don't know...
Refigure your math.
48x48 would be 4x the 24x24 and 24x48 would be 2x.
I would suggest 9' foot ceilings as a minimum. 4x8 sheet of plywood on the diagonal is 8.9'
I would bet at sometime you would have a piece of plywood up on its corner.
Consequently, I would suggest 10' ceilings since lumber and sheetrock are sold either in that length or multiples.
If it were my dime, then I would use 12' ceilings. It will keep a big room from feeling so closed in. Per my son the architect.
Um, no, I don't have any false impressions! There are many ways to get heat out of the ground!
One of the last ground source heat pump system I helped install had about a dozen heat pumps, ranging in size from around 1-1/2 ton to 20 tons. Water was run through closed loop wells, about twenty of them IIRC. The wells were drilled to aproximatly 100 feet deep.
I set up a couple heat pumps in a home a couple of summers ago where there was a water well drilled, again to about 100 feet deep. It was a "pump and dump" system. All the water that passed through the heat pumps was dumped in the ditch by the house and ran into the wet lands 1/4 mile away.
Before I showed up the company I worked for installed some ground source heat pumps that had a refrigeration loop in the ground. We have not installed any of these in years. They are still avilable, but seem to be pretty troublesome. Pretty much all we see in this area, the water gets brought to the heat pump, whether the water is a closed loop, pump and dump, or two wells, one supply well, and one return well. Greg

In some jurisdictions they are not legal due to enviromental impact. The posibility of raising the ground water tempurature was what was stated in the article I read a few years ago. Cost can be prety high to. I read a while ago that there was a firm a few years ago that would bury lots of copper about 10 ft down. Then just hook that up to the compressor of the heat pump and it worked great. But the repair cost got too high. If something punctured the pipe it was a goner.
On the downside it will not allow you to feel nice and cozy....
My shop btw is downright cozy.... too cozy....
LOL
Nice to see that today even your own son charges a dime.... used to be a nickle in my day....but my Dad was smart ...he never paid... Bob
Nothin' says cozy like 6' ceilings.
Nah. They say "Bring on the aspirin" because you'll be hitting your head.
