On our geo system, the loops were a little more than a third of the total cost. I'm sure that percentage would vary with the specifics of your site as well as the brand of equipment, any complications of roughing in ductwork, size of system needed for your specific house, etc. From my investigation, concensus was that the loops and their installation are critical to the success of a geothermal system, so I personally would think very hard about trying to do it myself even if I had the equipment and some excavation experience. We just decided that the far lower cost of heating with geothermal vs. propane here in Michigan was worth just about whatever it took to get it installed.
As for the insulation - yes I guess it was probably a lot more expensive. I actually did not even consider anything else, since with the full log walls we had to insulate fewer square feet than we would have with a conventional framed house (gable ends, dormer walls, shed dormer, garage ceiling) I decided to bite the bullet because of the air sealing the foam provides. It was immediately apparent that the house was tighter and with the R values of the foam, and the cold winters here in Michigan, it will pay for itself quickly. Hope this helps.
Hello from Missouri, Greg Beck here.
I was curious, I have considered geo thermal, was the most exspensive part the excavation, or the harware ? Looks like I could dig and lay the loops myself, also I noticed you guys opted for spray foam insulation, wasnt that insanly more exspensive than a blown celloullose ? I know foam is better, but the cost seems alot more. Thanks, looking forward to your reply, Greg Beck
Gail, thanks for the email back. WIth the Sansin, Light Honey is also the color we have chosen. I am wondering - HOW MANY COATS OF THE STAIN? 1 or 2 ? Do you remember? The color is actually what I am looking for. Did your contractor have any trouble applying the stain? With Heritage we chose the Woodhaven. Would you believe that I have already decorated just about every room, items are stored in very possible place in my home now, and I'm running out of room. If you could remember how many coats, that would be just terrific. THanks so very much for your help.
CJ from Va.
P.S. I'll keep in touch and when we start to build, I'll send you pics.
Hey Gail, its CJ from VA again. Just one quick note - your basement walls appear to be Superior Walls. Am I correct? My husband and I are going with Superior Walls. If so, how long did it take for them to build the walls? We will be building in the mountains here in Virginia close to the Blue Ridge Parkway. We are just so very excited, but scared too. We are the type of people that like to make the right choices the first time about expensive items. We are pleased with everything so far. Just waiting for the log trucks to arrive in the Spring. What a day that will be.
