Yes, Geome, too early. My geo is not up and running yet.

I'm no expert, but it does sound a bit early to me too. LoL
Please keep us posted.

We have 2 of our systems online, everyone can watch them.

This forum's purpose (and on a larger scale the one of the internet) is the exchange of information, and to help each other. Imagine 20 years ago, we were not able to disseminate useful info about newer technologies. Some people like to share, other do not want to bother. That is some of the freedom we are enjoying.
Lets be grateful that we can freely share, lets think about the guy in China or elsewhere where information is censored or not accessible at all. In a certain way forums like this are the ultimate democracy, everyone has a voice and will be heard. As long as we are courteous to each other and respect each other, everyone should be able to ask, and everyone should be able to deny an answer.

I am going to a have a nice shower now after a long day of work......powered by geothermal technology!

What is needed in this dark field is lots of people posting complete numbers on installs, and on annual BTU/$$$ numbers along with how well they all hold up, what issues all are having, what systems are working, etc.

In a nutshell,
Useful numbers must include heat load, price/kw and set point and heating degree days.
As has been said repeatedly each job is extremely specific and can't be guessed on square feet alone.
I recently gave a customer a "guestimate" based on info provided by web and a comp house. After the heat loss was performed we found we were nearly 20% off. Given that I have a bit of experience here I still make no promises without my due dilligence (a manual J load). Good news for the homeowners who require 1 less ton (a savings of thousands).
Point is you can look at what others save, but there is no substitute for custom calcs on your home.
Install cost matters as well and varies wildly. 
"Systems that are working" are those installed by competant contractors. Brand/type is of little consequence. How they hold up? Better than gas or oil appliances.

I am the author of more than one tirade here. A few of which I may wish a handled differently. I haven't been run off the site on a rail yet........but the night is young-LOL. Some of your questions sound more accusatory than simply skeptical and will necessarily offend those who install geo for a living or who spent 10s of thousands installing it.
Not to worry, I have found that my occasional flare-ups are eventually politely ignored when I keep my nose clean for awhile. ;)

In another nutshell... politely as I can state it. First, I am not researching heat systems for my home. I am looking into GEO for general and specific knowledge. And when it comes down to brass tacks, install cost/sqft and btu/$ spent are very interesting to me and to any of my clients. I am a builder, and admit have not installed GEO yet............

Example... Heat system cost $20,000/2,000sqft annual cost regardless of set points etc... in say Missoula... 5,000hddays, was $2.000 last year with propane at $2.00/gal, $1500 for propane, $500 for electric use totals $2000. Not including any other uses such as hot water, cooking etc. Then we installed GEO for $20,000 since system was shot, and costs dropped to $500 at $.05/KWH with hot water from superheater included... Yes... hard to separate.... I know... OK... so the propane includes all propane use... and the GEO now includes ac use all summer which was not affordable before. And the clients can't stop smiling.

I get it... in another nutshell sort of way...

I think this all started mostly because where I live and North of here... cold ground temps and $.14/KWH change the savings to much less than where many may save substantially. $.07 cuts costs in half as to here. HALF! That's a lot of greenbacks. And if the water temp is 10-15 warmer... again... more efficient... how much... that I do not know. I know a bit more now.... seems for very low temps the install cost goes up quite a bit so as to not have auxiliary heat strips start. And if using 2 stage units... costs go up.

OK... GEO is interesting. You all know... I am learning... with and without the knock abouts.

peace

nice post joe ami

Keep asking questions, as specific as you can, I will keep answering, as good as I can.

May 2008-Apr 2009 Heating bill with natural gas = $4785 (at $1.35/ccf incl. delivery), incl. hot water
May 2009-Apr 2010 increase in electric bill compared to the same period the year before (Heating bill now Geo) =$ 2465 (at 14c/kwh, incl.), incl. hot water

Moving adkjacUpstateNY future questions/issues/comments from this thread to a new one called (adkjacUpstateNY). Thanks everyone for making future posts there. 

docjenser... nice post of info... thanks... my calcs say you get COP of 5... and need 300 millioin BTUs. Wow. .. Big number... large home? SQFt?

OK... am posting this to new thread per the boss
