DIY Digging trenches for Geothermal

[Gofast]

We don’t have enough wind here for turbines and turbines for the home owner it is not a very good deal. To much maintenance and solar has come down so much in price wind can’t compete just add some more solar.
If you do a DIY install and use the tax credits solar has a pretty fast payback time.

The other day I got out my tractor and planted some grass seed.


We finally got some rain and the grass seed has started growing.


The Geothermal Ac is working really well and the two stage compressor is great.
Stage 1 can handle to about 95-96 outside then stage 2 comes on that is about right.
This keeps the humidity at a very comfortable level.

It will get better over time as the dirt settles on the geo lines.

If you have section on copper on the in and out you can put thermometer each then insulate and you should see about 10' difference.

I have a two-way communicating thermostat that gives me all the system info.
No need to connect up anything else.

I am no expert, but everything I have read, and everyone in the HVAC business I have talked to, said 2-4 degrees is about the norm.

You won't see a huge difference in supply and return loop temps, because of the shear volume of water flow. If the flow is slowed waaayyy down, then maybe you would get a 10 degree Delta.

His system shows 8.5

My loops are currently 5, 8, 7, 7, 7 degree different.

Early into either season the larger differences is understandable. Early into winter the ground hasn't cooled as much and more heat to be had. Same in the summer. Later into a season the differences diminish.

Are you guys running one pump or two? Pressurized or non?

 

[Gofast]

I have one three speed Grundfos UP2699FC pump. My system is pressurized. 4 loops one pump.

I dropped the pump down to medium speed for the summer. The winter it needs to be on high.

We just went through a couple week heat wave much higher than normal (for this time of the year). 97-89 degrees.
That raised my loop temp some but this is my first summer so I really don’t know what loop temps I will see.
