Just checking to see if anyone has geothermal in house or shop, any info on this would be good

I have the 10 kw backup element in case the unit cannot keep up with extreme cold but with below zero, it has not been needed. Matter of fact, I have yet to install it.
IMHO, the best combination is geothermal and propane. Propane for heating water, cooking, drying clothes and some kind of back up heat (fireplace logs). With a big propane tank, you could also run a generator for backup electric.
We are installing it in our current build. We used horizontal trenches rather than vertical wells. No difference in performance and less expensive but you have to have the land to do it. I'll let you know how it works after a year. We move in in a couple of months.
I for the life of me can not figure out how you can save money when the initial equipment and install is so high ? The pay back in my opinion is way to long when there is Nat gas available. And before it's payback is meet , you are looking at new equipment , not to mention the high cost of service when needed !
I have removed several of these units and installed hi eff nat gas units and the cust always comes Out ahead. One of them even worked for the Elec power company.
Not worth it IMO…
Lets say you spend $25000 on loop and indoor equipment. That is not an unrealistic number, thats not including ductwork.
Lets also figure a real nice air to air 2 stage heat pump and 98% gas furnace. $10000 would be on the middle to upper end of that without ductwork.
Lets also say we are going to get 20 years of service out of them. That isn't an unrealistic number at all, especially for the geo…
Theres 240 months in 20 years and lets say you're gonna save an average of $50 a month on heating and cooling costs. Thats only $12k you saved over 20 years… Spent more than that on the install...
Not worth it IMO…you're gonna save an average of $50 a month on heating and cooling costs.
Only save $50/month? LOL We will spend almost $3,000 to heat our house this winter! Betcha If we switched to geothermal we'd save A LOT more than $50/month!

It is true that if natural gas is available, the pay back time will be a lot longer than oil or propane.
You live in Munising, MI near the shore of Lake Superior. How many days a year would some one run their heat pump in A/C mode ? A dozen ? Certainly less than 2 dozen ! And over night cooling is pretty much unheard of up there ! Cooling is where heat pumps, either air sourced or ground water sourced, really shines and pays back.
You pretty much nailed the AC days of use , most times 5 - 7 days if you live in land . If on the water seldom at all.
I have spent some cold nights camping not far from Munising in July !
I don't think you can use a drinking water well for geothermal.1. If you already need a well, that is a plus. Our house is on city water, so the well was "extra".
Many (most ?) geothermal units run a loop of pipe down the well. A bit more expensive, but no discharge (well) is required.2. If you have a way to easily get rid of the water ... permissible river, stream, lake, marsh, swamp, woods downhill, field, pond, etc. ... that is a plus.
In some southern states, geothermal is MANDATORY for any new municipal construction (schools, etc).Question to the Forum ... why isn't geothermal used more for A/C? I would think that is where the big bang for the buck is. Every time I see a house or commercial facility on a well, near a place to dump the water, with lots of glass and square footage and see the outside A/C units whirring away ... I think "why not geothermal?"
But very few would be stopped buying a $30k vehicle. And that won't last as long. But your HVAC system doesn't get you to work and back.
Another great thing about geo is that you don't do setbacks. So getting up in the middle of the night is as comfortable as in the morning. Just the savings of not having to buy nest devices shortens the payback period. Those things are pricey.
