ReplyOne GPM? Must be a mistype or I read something wrong. 4 to 6 GPM would be the min. for a 2 1/2 ton unit. I quess he could put in a tower and only run the unit every couple of hours for a few minutes.

I have a house that I am getting ready to install a 038 ttv climatemaster at, the house has a 2.4 ton cooling load and I was planning on using two 300ft vertical wells with one inch pipe. The water well driller on this job drilled a 650 ft water well that only produced one gallon a minute so the owner is asking me if we can use that well and just do a single 1300ft closed loop. Have any of you guys installed a loop this long? bigger pumps? efficiency issues? Thanks,
Bryan
BTW drilling and grouting are very high in my area 18-ft.

the one gpm number is for the unusable 650ft water well that we would change to a closed loop 8-9 gpm well. (one loop, pressurized and grouted top to bottom)

The original well was for potable water for the house and it just did not hit enough water so we are trying to make lemonade out of this lemon.

You're going to want to step up to 1 1/4 pipe to accommodate the 9gpm needed by the ttv038.
650 vertical feet of pipe should be more than enough for a 3-ton system depending on where you're located. If you have access to ClimateMasters GeoDesigner software I would run it through that to confirm.
As far as pumping goes, you'll likely have to bump up to a dual 26-99 flowcenter for this one. (that'd still be much more affordable over the long haul than drilling 2 new holes in the ground).

Did they hit magma?
It should be fine to use as long as you use the proper piping and circulators to get your GPM right and reynolds number within line.

yea...high heating loads and hard rock require those kind of depths

We had an 800ft artesian well drilled on a ranch I worked on. It was capped off like an oil well, the hose coming off it was the size of a firehose, and it would fill a 10,000 gallon tank in about 45 minutes.
The water temperature coming out of it was 79F. They used it to heat their house in the winter.
