I also installed one of these systems. Here in So Cal hardly anyone has heard of them. The contractor I was using went out fo business half way through through the project. Drilling and trenching costs are astroniomical and I don’t know why. I rented a trencher and put in the rest of the pipe myself. I’m still not sure I have enough pipe but my ground loop no longer overheats or over chills. I have yet to get a handle on the efficincy of the system because I doubled the size of the house and the old heating system was resistance heat in the ceiling so it does not compare. Bills on the double size house are lower than with ceiling heat though.

From what I can tell these systems are much more common in Indiana and Oklahoma. Anoyone else have one in So Cal?

While it’s difficult to put a price tag on the benefits to the world of green energy, I actually bit off one of these projects for my dream home and was a bit astonished to discover how much this added to the price of my home. I bit the bullet though. Did it “anyway” thinking this was my “forever” house. Now I’ve gotten divorced and had to sell the home and it was a very tough sell. I’m sure the new owners are happy now after a year of low heating and cooling bills, but to ask an extra $30-35K US for a home is difficult. Does anybody know what is being done to make these systems more affordable? When I did mine, my state had zero tax incentives for such systems.

You’re absolutely right, I could have made the distinction more clearly. I was really just trying to introduce the video, but I also understand that I muddied the waters a little.

I think you need to draw a clearer distinction between ‘geothermal,’ which uses energy from heated sources beneath the Earth’s surface, and ‘geo-exchange,’ which uses the Earth as a steady-temperature heat sink. The distinction is much the same as that between a furnace and a heat pump.

They are two different technologies. Geothermal is location-specific, while ground source geo-exchange can be used anyplace.

But I appreciate the video clip you found about geo-exchange, and I’m going to have a follow up article for Green Building Elements.
