Geothermal Ground loop Installation

[LaserBeam002]

Since this vid was made there are now DIY kits for Geo heating/cooling. I am thinking about going with Geo. Please tell me...How comfortable is the heating and cooling? I live in South Carolina and I think the enviro would be perfect for this type of system.

Im going to school to b a HVAC TECH heat pumps installation is 1 of my classes.

how much did the whole geothermal cost total?

[jimdonnel]

I hope that home is a place that does not get very hot or very cold for long, with 600 ft or even 1800ft of pipe that system is good for maybe 2 tons at best. Oh wait that must be why they added the water from the well so they could keep it wet, lots of water from the well will work but, that will cost you.

[VeritasAmantesVocat]

did somebody say Westinghouse??

i have read that sand is one of the worst soils to use for conduction and heavy clay work a lot better.

Cost: about $2,500 per ton. a three-ton unit costing roughly $7,500. drilling can run anywhere from $10,000 to $30,000, or more depending on the terrain and other local factors.

Next there'll be a new technology getting heat from drilling close to the volcano, but not enough for it to erupt.

Great job.

[dirtydogvideo]

excellent vid. thanks for posting!

[adam5201]

600 feet total? How many square feet was the house? How many ton unit?

I don't quite understand why contractors don't use copper geothermal lines instead of PVE. I know there is a reason; however, I am thinking it seems like a good idea to put in a copper grid that would distribute the pumped water through a "gridded" field. Please let me know what your thoughts are.

@ponyryan

12 and 16 year failures from ground soil chemistry eating up the cu dx?

replaced 3 in last 2 yrs with Hydro- Temp .com full heat from compresors in cooling as HEAT-RECLAIM 100% ! WF just copied 1980 Patents... STRAIGHT LINE gt poly lines and ~ 12" apart for 4 in a 3 ft wide ditch or 5 in a 4ft wide ditch, 4.1/2 tons of rated -size { thats to 50k compressors 240ft ditches engineered since the early 1980's !

see expert geothermal net

@ponyryan .

one of the reasons PE pipe is used is that there are no joints and if joints are required then its fusion welded which is a much better joint than anything you could do on copper if your going to bury it. also copper will corrode after quite a short time where as PE will last 100 years or more.......and then theres the cost of copper !!

I've seen at least three different ways that the tubing gets laid out. What's the benefit to the "slinky" loop system vs a straight run type loop?

[CurtRLarsen]

You get more fluid in an area space by looping the piping versus a straight line pipe. If you have 100 ft of space and run a single line out, you have 100 ft x the diameter of the pipe = x Cubic feet of Fluid.

If you loop it around, you have the circumference of the circle x diameter of the pipe = X cubic feet and multiply that by the many circles you can fit into that 100 ft of space = more fluid, which makes more efficient heat absorption for heating or cooling.

[fetymann]

that's cool, I've never thought about burying caution tape. I'll keep that in mind.

[AdirondackNY]

nice job, and using the water realy helps the sand to settle around the pipes so no air pockets that could settle and kink a line

[eebuilder]

The manifolds were located in the mechancal room and no connections were needed below grade. If a weld was to fail it is easy to fix when easily accessable.

[AndyL420]

Bringing all your circuits into the home to make a manifold must take up some serious room.. We put our headers in the ground , pressure test after backfil, that way in the mech room we only have 2, 1" 1/4 header pipes entering the house. either way has pro's and con's

[thatguybikes]

Where are the slinky manifolds located? In the trench? Or in the Mech. room?

Thanks

[salserops]

So how deep of a ditch would a closed loop horizontal system need to be to chill the water to 55 degrees Fahrenheit? 10? 15?

Location: Palm Springs, ca

Climate: Desert, 120+ degrees in the summer.

Tap water: comes out at 71 degrees. From the water tower to the street water is delivered 4' to 6' underground. The last 100' on my property is only about 1' underground. I would be interesting in cooling the water down to 55 degrees.

[nhojcam]

did they pressure test the slinky loops before backfilling? just curious.

[johnkmd]

the pipe has pressure in it. its sealed on both ends.

[AndyL420]

you can pressure test before, but during a Backfil it is just as easy for a rock or some foreign object to kink or put a whole in the pipe. If you pressure test after the backfil and all is well, then you know 100% the loop will operate fine. If you were to pressure test before backfil you still leave room for error on the loop
