With loops being on average 30% of the install costs, and the federal rebate being 30%, you are going to have to put more thought than that into a reply......

I would champion any form of geo exchange or high efficency air to air before I ever looked at putting copper tubing in the ground. This type of exchange is known as DX, and it is a unproven and...
Just a quick note. I was talking about the equipment only being 20% more in cost, not the whole job. I thought that was the OP initial complaint? Or was he talking about the whole job?
Eric
I would add that the pricing is very geo - centric. Meaning in areas where geo is done as a regular install, not a big upgrade the pricing of the units is about a plus 20% over air to air. In my OA...
There is no such thing as the " geo police ". I would claim the credits for the cost of the whole install and not look back. I doubt anyone who ever pulls your fathers shoe box of reciepts for the...
My reply was meant as humor as well, lol. I would love to see a picture of that set up the next time it lands back in your yard. We used a auxilary drill pump, 25hp 3x13 centrifigual plumbed to the...
Does the reversitron 169 mean you just reverse the hoses??? Thats the way we did it, untill the volume of jobs pushed us into something with a few more refinements.

Nothing to fear when loooking at the loop. As said the diagnosis should go to the gas last. The pressure in the loop will vary with operation, so really there is no set pressure for the loop. The...
Commercial or residential?
The one I designed and provided directions for is on our website under DIY purge cart. GSC sells one for around 3,500.00 I think. There are other options if this is a...
It is all about the economics, and I think you answered your own question. Geothermal is more eco friendly because it's only carbon footprint is the one left by electric generation. If you can...
Curt Kinder in n fla. hooks up the discharge on his open loop geo, tweaks the flow to get the temp right, and lets it fly through a commercial snow nozzle he got on e-pay to keep the kids in his hood...
The method you describe is 1 way to do it, but not the only way. I would assume that since we are talking about prints and a bid, it could be DESIGNED for 90% geo with the apropriate manual D. The...
I clicked he other button in the poll. This all boils down to the numbers and trade offs. I would advocate sizeing the geo to handl at least 85% of the heating load depending on the cost of...
I do not feel that heat transfer would be an issue, it is just goop. I would expect it to have the same transfer rate as the concrete we are sealing.
Technical note: my zone is not Nova...
Hi,
We use a granular bentonite product that is commonly used in the drilling industry. Benseal is one trade name, 8/25 mesh bentonite is the spec. When mixed with water it creates a watertight...
The tax credits will not expire before 2016, barring any bankruptcy proceedings by the govt. lol

This has been discussed add nauseam and it boils down to " a given volume of water, at a given temprature, with no means of reverseing or adjusting the temp, only has a given number of btu's to give....
I am going to be the voice of reason and experiance here. If you have the patience and monies to be your own beta tester, and live with the results, go for it. If not the latter, get off the...
Getting ready to cook for the guys for our annual Christmas Party at the shop, waterpirate style. I have an entire Dell Roll aging, and the cooler is full of everyones favorites. No one ever leaves...
The bottom line is that the rehau system of double loops is a good one for a stable, air rotary rock drill. It is not a viable option for mud rotary, given the unstable nature of mud rotary bores...
I have peeled that onoin before in regard to my opinion. PM me if you want to hear me rant. I researched the job, and the specs add nauseam, and chose not to bid. That caused the owners engineer...
Your ground water remains constant, as in a pump and dump. A closed loop does not remain constant. To answer the original question.... I ave had it explained to me a half dozen times and it allways...
The real deal breaker is and allways will be distribution costs. Currently nat gas is only available in our area to high volume end users. Us peons were deemed unworthy for connection options when...
I would argue that natural gas is a poor choice for AC. lol
Eric
Warning! geo forced air units, and geo radiant units are two entirely different machines. Also adding load to a heat exchanger later is also not adviseable unless planned for upfront. Geo is a...
Sorry no one wants to support your engineering solution, but.... The fact is you are barking up the wrong tree. Hooking up the circulator pumps with the flow going in the WRONG direction is prolly...
I agree with the above. Research a competant tech/company that is familiar with geothermal add-nauseam. A correctly skilled tech will save you thousands in time, energy and comfort.
Eric
This is not the helix. It is a conventional loop per se. However the loop is pexA not hdpe. They condone 2 loops in one hole, with spacers to reduce the footage and number of holes that need to be...
Does anyone here have any experiance installing or useing the Rehau double loop pex system? Good or bad I would like to hear it. Feel free to contact me off forum if you wish, public would be...
LOL,My weber was used when I got it. When I upgraded it was because the weber beyond its service life by about 100.000 miles. I like having the choice of going charcoal with a beer or turning on...
I upgraded to a triple threat 2 years ago and absaloutely love it. I have a gas grill with side burner, bolted to a charcoal grill, that has a smaker box bolted to that. In my mind it is the best...
I would go on the Web Energy Logger site, and see if there are any dots near you that you can view real time data on. The people I have contacted via that site all seem more than willing to talk...
All of the charts are unit specific. That being said anybody's chart can be used for a good fuzzy feeling. They normaly are close if you are looking for a gut check. Make sure you are looking at...
Good on you! And thanks for the compliment.
The loop side of geothermal does not have to be complicated. It functions on a set of rules that if you understand the basics of fluid movement and...
I think the real issue is what is legal in the place on the rock you work in? We prefer methanol when allowed, but other states have other ideas.
Eric
Ditto,
What he said, +1

One of the biggest snafus IMHO is the incorrect setting of the thermostat. Your thermostat is so much more tan a slave to the unit, it is the brain that tells your machine how and when to do what. ...
I must have missed the part about the thermal conductivity test? This is crazy expensive for a resi project. We typically charge 8-10k for that testing. What are the costs associated with your...
I would be very skeptical of that loop design without some real world data/ customers who were happy to back it up. Drilling in rock is costly as you know but shorting the loops to that extreme will...
Hi and welcome,
What you have there in your diagram is the "fischer price" diagram that explains how a geothermal closed loop system absorbs and disapates heat. Closed loop being the operative...
The danger with muriatic acid is that it disolves alot of things. One of which was the solvent welds on schedule 40 pvc. I hope to never repeat that nightmare! When looking for a solution to...
Given the amount of hot water usage just figure out what it costs to produce and maintain 160 gallons of hot water useing electric vs. the cost of fuel for the tankless being fed with buffered water...
Again the question comes back to how much hot water does your house consume, in the 2 peak periods? Before work and after dinner. If you do not have high, intermittant, or consistant hot water usage...
Typo alert. t.p.s. were the reports that they did in the movie "office space" with the red stapler. lol
t.s.p. is tetra sodium phosphate commonly used for cleaning all sorts of things. Mechanics...
Everything in the world revolves around economics, and usage. In my application the high intermittant usage took geo hotwater off the table as well as storing that amount of hot water for...
When I gutted the boiler at my house and went geo, I lost my domestic hot water loop. So I was in a quandry. In my case it made sense to install a tankless propane dhw over geo because I have a 350...
Where do you think that that you should address the " powers "?
In a poorly lit room behind some beer garden?
Freedom of speach, even on a privately owned and operated board should be...
This site had a volatile past from what I understand. Tightening up the rules and so forth was to keep the site valid and usefull. Add to that the concept of " the first rule of pro status is to...
The whole concept is reffered to as a " geo battery " and all the math I have seen on operateing it, the pool/or burried tank is allways followed by how much btu replenishment of the battery in fresh...
