Geothermal System Using Horizontally Bored Loop

In moderate climates that is

It seems like inverter air source heat pumps will soon squash Geothermal dead

What type of heat pump are you using?

I noticed that you didn't insulate your loop pipes inside the house, do you ever have condensation issues

I am curious about how much cost per 100 foot bore? We would need 5 ton (500 feet) total. Drilling costs seems to be big variable here. Mostly fractured limeston 'Karst' geology?

[Ecohillsolutions]

A rough estimate is $2,200 per ton with bentonite and this includes the loops into your house.

I was wondering why dont you dig your manifold pit first then drill through it, instead of risking hitting the pipes trying to dig it after the drilling is done? Have you considered making a 12"x12" hole in the floor by the furnace to drill to for your supply/return instead of going threw the wall? You might find to be less prone to leaks and cracks. I was also curious how thick your mixing the bentonite.. 2 bags per 500gallon? this is a much debated topic right now (bentonite grouting)

[Ecohillsolutions]

Yes. Our usual process is to trench and run the bore. This day the trencher was "stuck" at another job so we had to carefully executed this. Up through the basement, is a very viable option depending on the size of the footings. Four and five foot frost walls are common which enters in to the decision making process.

Regarding the bentonite- depending on conditions, but we are finding 2 bags isn't enough. We use pure bentonite now and putting as much as 6-7 bags /750 gallons.

Thanks.

What do you use to mix the bentonite that thick and pump it down hole? Ive never tried it but it doesnt seem like a MX125 and a 30gpm water pump on a drill would pump it that thick Thank you for the insight

[Ecohillsolutions]

It's the thickness of a milk shake but the borerig's pumps handle it no problem.

[wuboring]

Thank you for the information.!

[Ecohillsolutions]

It's a pretty smooth and clean operation for sure and

for large jobs-have wagons will travel!

[bozcopcspecialist]

Very clean on the drilling part and so fast it makes it look so easy. Hope we get this going here in Texas!

My family lives in WI, so I was pleasantly surprised to learn that you have already drilled in my neighborhood! Your video was very informative, interesting and it instantly eased a lot of my worries about expense and the possible size of the operation. We have been thinking about making the switch to geothermal energy for a while now, and your video explained a lot. Expect a call from us soon!

[Ecohillsolutions]

Thanks, Sarah. We look forward to assisting you.

We are changing the way these projects get done. Without an independent design customers are at the mercy of general contractors. The process isn't rocket science as you can see, but getting the right sized system at the right price is where EcoHill llc is helping resedential and commercial properties. Knowledge is power for these projects.
