We are building a 2,300 square foot Log house for 4 years now.  The basement walls are  concrete insulated forms 10" concrete with 2 1/2" foms on inside and outside, radiant in concrete floor.  Main floor is speedfloor with 3 1/2" concrete with radiant in  floor,  log walls are 10" to 12" foll round logs with chinking between logs.  Concrete forms, speedfloor and geothermal was purchased from Arit.  Mark Ross and Scott were here to do install of forms and speedfloor with radiant.

We are now ready to hook up our geothermal .  We purchased a Tetco ESII- 4.0-DSH  with electric back-up installed.  We also purchased W62.   7 terraloop 3/4" 750" ea precharged for slinky loops.  We have decided not to do the slinky loops.  I will sell for half price if anyone interested, terraloops.  We had 2 wells drilled (Holes, closed loop) 300' each. 

We are not sure of the hook-up of the geothermal now with the change from slinky loop to vertical closed loop.  I have tried to talk with Nick, but he will not return my calls!When Arit went out of business I did not receive all of my purchased items.  I have tried about 5 times.  No return calls.  Cannot locate Mark Ross

Looking for some help around Hazleton, Pa

did well driller include vertical loops...are these 300' loops or 300' wells?

Well driller included loops in both of the vertical holes

Sorry, didn't answer all the question. There are 2 vertical holes 300' deep. They have 300' of 1" tubing down and 300' coming up. There are 2 of them

?

300' closed loops

so that would be 2) 300' u tubes for a total of 1200' of pipe with a 150' average depth? (am I pulling teeth here?)
That is what I would expect.
I would manifold them in paralell everything else would be the same indoor hook up as the slinkies.

(Maybe if you are a dentist). I'm sorry I don't have your expertise or language of the geothermal. But, then again I would not be asking for help if I knew everything. We just don't want to hook up the system wrong and have it fail. You are correct when you stated 1200' of pipe, but when you state 150' average depth. I am not understanding average depth, why would it not be 300' average depth?

Two 300' bores might support a 4 ton unit in your area.

I think you need a local expert. Have you checked at IGSHPA for a trained contractor near Hazleton?

Thank you, I will look at IGSHPA and see if I can find someone

top of the hole is 0' bottom is 300' average depth is 150'.
I agree with Engineer to find competant installer. Also have them make sure your unit qualifies for tax credits.
good luck,

I am near Scranton and have a GTHP system with a 4 ton system and 3 300ft vertical bore holes. I have a lot of information as I'm also a licensed water operator. You're welcome to contact me if you need advice.

Joe, where I went to school you would figure average by taking the total depth of each well and add them, i.e. 300' + 300' = 600'. Then you divide by the number of wells which is 2. This gives you an average depth of 300'. Now if you are wanting to determine the median depth you would divide the total depth of a well by 2 which would give you a 150' median depth, i.e. the same number of feet above and below that number. Make sure you are using the correct termanology and doing your math correctly, particularly when dealing with someone unfamiliar with this subject and pehaps where english is not there native language. Also, colloquialisms such as "pulling teeth" would not make sense to someone unfamilar with this subject and language.

The average depth of a 300' vertical borehole is 150'

Once you get below 30' deep, average depth matters little. Ground composition and moisture matter more

weldboy anyone in the industry for a period of time should have known what you were talking about when you said 2 300 ft bores. you need to contact your local expert, but be careful many new people can be certified not qualified. your loops should be piped in a reverse return configuration so your units can operate off all of the loop field making it more efficient and keeping your loop temps higher or lower depending on what season you are operating in. keeping your loop temps right translates into higher efficiencies and money in your pocket. hope this helped.

For those of us who design loops, we know that a 300' well has an average depth of 150'. All loop design programs use this methodology. If you want to be in the geo business, learn the lingo.

I am in basically the same boat as I bought my WR26-G from Arit as well. Tetco was and is not very useful in tech support however they have been bought out and new owners are trying to support the older Tetco products as best they can with the limited resources available to them. I contacted them today and the guy is at least trying to get documentation for me.

This is Tetco’s Website and they have information posted under products discontinued that may help you. tetcogeo.com

You may e-mail me at [email protected] put Tetco in the subject.

I don’t know how current this contact information is but for what it is worth here is nick and marks contact information.

To the helpful new pros here; you haven't learned yet that DIY's want to use our jargon which is why it pays to ask questions (as they often don't know what it means). Since a 150' u-tube is 300' of pipe or 600' of pipe would go in a 300' well, confusion has occured there and wasted a lot of time. Further average depth would be average depth of single loop in trench or wells that there are 2 wells or multi loop wells does not make the average deeper.

As far as not using colorful phrases......get outta my grill :)-
