What does it cost to have a geo wells drilled? I have seen several web sites that drill smaller dia holes than the typical water well. The drilling equipment is much smaller as well. Top layer is sand stone, but could be limestone once deeper.

That typically varies by geographical location.  Not only due to rock formation, but also travel expense for the driller, and the amount of local awareness.

Typically, a "midwest-borehole" will cost between $1100 and $1600 per ton.  Some areas are in ecxess of $6,000 (some eastern US areas)

I had one six inch well drilled 150 feet deep. I used a submersible pump to provide water to the heat pump and for household use. The heat pump discharged into a pond. The well was bored by an amazing drilling rig that did it in just a couple of hours. In Ohio, it cost six thousand dollars including the pump and pressure tank.

in Utah geothermal wells cost  $1500 to $3000 each  depending on location and quantity of wells to be drilled

here in saskatchewan canada the goin rate for verticle loops is $4.5 to $5 a foot for holes 100 to 200 feet, 3/4 hdpe pipe, fused and pressure tested into yer house. my driller is here and supposed to be drilling mine in the next few days. thier rig is a modified siesmec survey rig.

I have talked to three companies around the Washington DC area.  They want $9000, $12,000 and $13000 for 600-640' (two wells) of drilling for a 4-ton system.  That price includes installing pipe all the way into the house (a little trenching and core drilling into the basement).

$10 per foot here in North Florida

At our last home we paid $10/foot just for the drilling part, it was just over $2000 to get them on site, prep and cleanup.

Southeast Pa - 15.50/ft complete (excavation, drilling, piping, grout) to house.
Extras were:
         Time and Materials inside house to units and insulation of the pipes.
         Propylene Glycol
         Fill/Flush/Pressurize

2000 ft in drilled wells and about 50ft inside house for three separate loop sets (6 lines in-out) ran approx $30K.

Does that mean you could DIY a geothermal system? If the well was already dug, and pressure tested...

There's a lot of open loop systems around here. If the water quality is good and you have the capacity to both pump it out and someplace for it to go, it's very efficient. Several companies sell package units that you can hook up to your duct work, your water source and disposal and electric service and be in business. You still have to do your homework to select the right size, model and make sure that you understand what is needed before you buy any equipment.

Don't forget to factor in well pump power for open loop - it can be quite significant.

Hi all,
I see some familiar handles from the other board.
On the Delmarva Penninsula we charge 1600.00 per loop, or ton of load. Typically 3/4" loopsX200'.
This price includes: install the loops, dirt work, manifolding, methanol, pump pack, hook up to units, purge flush pressurize system. For every four loops of load you are eligible for another seperate pump pack if you desire.

Hi Eric,

Welcome aboard. You are providing a lot of product and service at a very reasonable rate. Way to go.

Hi Dewayne,

Practice makes perfect, and efficency makes profit.

Here in central Arkansas, I was quoted $5/ft to bore the holes and it takes ~200' of well per ton of capacity. This is just the cost for the well driller - pipe and labor to install it would be extra.

Hello, I am the owner of a drilling and blasting company in Rhode Island. We have drilled five systems now. We are trying to get our cost lower and we price each job individually. It is better for us to have solid ledge on site as we use tophammer drill rigs. The advantage seems to be the speed. We average four 100 foot holes per day and have a pretty good record of six per day with twenty feet of overburden. The cost associated with drilling has many factors. The most expensive for us is the cost of the drill sleve set up. We also are limited to 110 feet in solid granite but we are involved only with the DX systems which require up to 100 feet. We also install the loop, grout, and provide the excavation. Check our web site at: www.accuratedrillingandblasting.com

We pay up to $3,000/ton (150' u-tube) in MI.
