Walls are 2x4” on 16” centers, half inch of plywood, 2” rigid foam, half inch OSB, and the outside finish will be brick

Just curious - what does the outer layer of OSB buy you?

835 above ground square feet seem like you could heat with a candle.
Definately wanna spend sometime exploring envelope improvements to keep system modest- conventional or all electric might be sensible.

ICFHybrid, it's amusing...

What's amusing is charges of bias coming from someone who so clearly has an interest in promoting one particular solution such as you do with geo systems.

Duh, this is a "Geothermal Forum"
You made my point - you are only pushing mini-split solutions!  What's the difference - this is a "Geothermal Forum" 

It's like arguing with a child.

Doesn't matter what the title of the forum is. Just because a post ends up here doesn't mean the opening concept is what will work best.

I've discussed any manner of solution depending on what is indicated. I don't have an interest, economic or otherwise in any particular thing, but it is clear you have a limited range of thinking, for whatever reason, economic or otherwise.

Maybe you had best stick to discussing the issues rather than getting all worked up over personalities.

As was pointed out earlier, the relevant issue is that you defend mini-splits and their installers, and not geothermal systems and their installers in a geothermal forum.  Your claims that you do not have an agenda are meaningless to anyone who has kept up with your posts.  Another important issue is that you have no geothermal experience and fail to disclose this.

Licensed engineer (with PhD), and you don't have the first clue as to what my experience is, geothermal or otherwise. Did you have any off-grid "geothermal experience" to share with us on this issue or just more smoke to cover your insecurities?

To date, you still have told us nothing relevant about any geothermal experience you have.  There are many smart people with and without degrees, and many not so smart people with and without degrees.  Sounds like you believe you are smart, or know about geothermal, because you have a degree.  I believe your reasoning is flawed.

Never claimed to have off-grid experience - it's not in my signature (get the point regarding disclosure?)  However, knew enough to dispel your misinformation regarding geothermal power usage earlier in this thread. 

get the point regarding disclosure?

Nope, still don't. Maybe, it's more important to you if you are trying to sell yourself.

Never claimed to have off-grid experience

Well, to use your own flimsy logic, why are you posting in this thread, then? LOL

Of course not.  You have no clue regarding right from wrong.  You imply that you have experience that you do not, give bad advise, and who cares - not you.

Well mr phd, someone needed to clear up your misleading information regarding geothermal power usage. 

someone needed to clear up your misleading information

What "misleading information" was that?

You have no clue regarding right from wrong

I see.

And this odd obsession you have with me as a poster required to make "disclosures" is.... what.....

Is it "right" or "wrong"?

Did you lose a geo job over something I said or something?

Either reading comprehension was not a requirement in your course of study, or you're trolling.

Are there any other people in this forum who think that I am in any way affiliated with the geothermal industry?

I really hope you're trolling.  If not, I honestly, with all sincerity, feel sorry for you for not knowing any better.

The outer layer of OSB was added for the brick installers. It did not buy me anything but did cost me.

longgravelroad, See if I have this correct: The plywood was for bracing, the rigid foam for insulation, the OSB for the brick layers. Did the brick layers attach the brick ties only to the half-inch thick OSB or did they use long fasteners into the 2x4's? I am not being critical but I am curious.

The brick layers used 4.5” screws with there ties. The studs were marked on the OSB.

The plans for the house did not have the OSB but the brick layers I talked to did not like the idea of putting there ties on the foam. Asked about using large washer between the foam and the ties and after trying it I saw what they were talking about with the compression of the foam. If there was not a solid mass on top of the foam the screws would wiggle around (expansion and settling).

How do they do it where your at?

Brick ties nailed through 1" foam and OSB into studs. No second layer of OSB or plywood.

I see these, but I wouldn't be surprised if they cost more than OSB. I like the idea of rigid ties going on before the foam.

I looked at the veneer anchors and they look great if you get the brick installers to put them up before the foam. It also looks like they would have to be pretty close on there measurements or they would not line up with the brick. It also looks like a good size chunk of steel right through the foam.
