Cost Of Geothermal Units

ciws14

And with all systems unfortunately, those "10" with no payback have been improperly installed. More than half of my pathetic life is service calls on Geothermal systems that have not been installed correctly. If they are not sized correctly, installed or used correctly, then no, there is no payback. Like PalaceGEO mentioned, it is downright frightening how many "HVAC" contractors know little to zip about Geothermal systems, but yet are 'experts' on the payback of them.

I have bid on a few projects that had Geo thermal heat but have yet to do one.

My HVAC sub tells me it cost just as much as gas to run. He tells me when you read what savings you could realize it is comparing costs to electric.

Is he BS ing me?

ciws14

I'm not sure if "BS-ing" you is putting it correctly. I truly hope he does not believe what he is saying and telling you. This is a fine example of what I run into all the time. Once again a contractor knows little to nothing about Geothermal, but they bad mouth them. Perhaps he once had a bad experience with one. I'm not sure, but that statement could not be more false.

Your most efficient Modulating furnace right now is 98% AFUE. This is fantastic and it is about time. This typically meaning that out of $1.00 of fuel that is put into the furnace, theoretically, you are getting 98% percent of that energy out of it. Again, theoretically.

With a Geothermal unit, most now have a COP of 5 or more. Meaning that for every 1 kW that is used in a Ground Source Geothermal unit, They retrieve around 5 kW of usable energy that is therefore put into your home.

Palace has a much more interesting way of explaining this... Hope that helps...

I'd say about half are installed right.
The other half, maybe not.

There are many areas, with gas rates low enough. That a geo doesn't save much over gas annually.

Yep. There are many that are installed with wells that aren't deep enough. or improper grouting.
And others on under sized duct systems.

But, for the cost of the wells. You can pay for a lot of gas to heat the house, and a lot of electric for the air to air A/C, or heat pump.

ciws14

That can be true... For the cost of wells... That why there are several other methods of Geothermal installation with regards to loops, open or closed.

palacegeo

Yes...unless the gas rates are way low and the electric rates are way high.

palacegeo

beenthere....not trying to pick a fight, but would you care to tell how you became an expert on geo systems?

My credentials are listed on every post I make. We know nothing about yours.

And since ot all options are available to everyone.
Not all geo can have a reasonable payback.

crovello

I never really understood how geothermal can heat your house. Do you know of a site that gives an explanation of the basic workings of it. I would love to read up on it. I would imagine that customers must want to know how it works before they invest in system that is so different than they are used to seeing.

Thanks

Palace,

How's that sonic rig working out for you? Is maintenance as big a head ache on those as I hear?

The Sonic Rig has been great. We have been drilling since June, have drilled about 16,000 feet. Just routine maintenance so far.

Palacegeo,

I'm fortunate to live/work in an area where horizontal (slinky method) is the norm. Lots are large (2/3 acre) and usually sandy clay soil. This knocks the cost of geo down dramatically. I'm just trying to get an idea of which brand of ground source heat pumps are preferred, and I'd like to get power consumption specs, and things like that. Can you point me in the right direction? Thanks

palacegeo

Cache,

Are you in Logan? Email through my website that is posted in my signature. I don't come to this site often.
