Re: “I'm wondering if you looked into this for your new house”
No. I don't know anyone in this area who installs such things. I'm not too interested in being on the bleeding edge of some new technology that's going to run me twenty grand to try out and probably doesn't work as flawlessly as some would lead you to think. I find it difficult enough to get the heating/plumbing people to do their jobs with regard to the OLD technology. Your article says the guy twice had to repair his system. That's fine if you're an electrician or at least an electronics guy, but I'm not. So, when it goes out, will I be able to call up my plumber and tell him that my geothermal heat pump is on the fritz and to bring his oscilloscope? Probably not. This sounds like it's the kind of thing that a highly inventive, hands-on type of guy would just love in his own house. You, for instance. Please let us know how it goes.

It also sounds like something that could easily be put in at a future date, perhaps down the road when a lot of other people are demanding such a service and my small town opens up its own geothermal heat pump dealership. A whole lot of trenching in the yard, and a fairly small hole through the basement foundation should do the trick, right? I'll do that when support for the technology is readily available.

BTW, "heat" won't be problem if I get my external boiler up and running. I have a virtually inexhaustible supply of wood energy and foam insulation that should hold in the heat. That's quite experimental enough for me. Nearly half of my house is also underground, naturally benefiting from geothermal warmth. But even without heat, the place will be fine. My part of New Hampshire doesn't get as cold as you might expect: A winter cap... a pair of long johns... an eighty pound dog sleeping on my chest... and I might even find myself TOO warm.

I'm wondering if you looked into this for your new house. It sounds like it pays for itself in about eight years OR LESS. I'm thinking about it for an upcoming project. Sounds like you need at least 1800 feet of run. It isn't clear if there is an advantage to going straight down, versus just trenching at 6 feet or so, but there is obviously a huge cost savings for the latter, if you have the space and the ground can be/needs to be trenched anyway.
