It sounds good except that I have never had this problem before until two weeks ago and I have had 24 plus hour runs before.

Do you have trees or other structures that can shade your home right now?

Is it your recommendation that the homeowner should either plant,  or cut down trees to fix his geothermal problem?

klatunickto, you would be well advised to allow people with geothermal experience to help you and disregard comments and questions of ICFHybrid, as he has no geothermal system, training, installation and repair experience.  If somehow ICF stumbles onto a relevant question (even a blind squirel finds a nut every once in a while), the pros here will let you know that they need it answered.

I'm sure he will respond to some specific non-relevant aspect of this post, internet trolls do that to get a reaction, but observe that he fails to mention his total lack of any geothermal experience in his reply and consequently tries a shotgun approach to questions.

Not at all. It's curious that he is experiencing issues at noon. Ambient temps have usually increased by then, reducing heating demand. He may also have his home shaded in such a way as to delay the impact of insolation. Since shading is dependent on the time of year, we were investigating that effect as well. It would be hard to imagine a situation in which "planting trees" would improve the performance of this heating system

I hope you don't think that "geothermal experience", as you might know it, represents the pinnacle of thermodynamic engineering or control systems technology.

What Masoud speaks of is an automatic reset feature and a good guess.
It would show symptoms you describe (especially if your aux. is not activated). Have you done anything to system (i.e. turned off aux breakers)? Is fan on on or auto at the thermostat?
Next time you think it is not running correctly I want you to measure the pipes entering and leaving water temps.
Use one thermometer. A meat thermometer from anywhere is fine. Put it between the pipes and the insulation (actual number is less important than difference between the two).
I'm betting you'll find no difference.
Next you need to familiarize yourself with fault codes and how to get them.....as engineer says, dangerous voltage within, so educate yourself well.
If fault is LP (low pressure) it is typically water side trouble or bad switch. If it is HP (high press) it is typically plugged fan coil or filters or bad switch.
I've no reason to suspect loop design problems at this time.
I do have reason to suspect pressure switches' durability.

So, you are an expert in thermodynamic engineering or control systems technology?  If so, you believe that this will help the homeowner with his geothermal problem?  Ok, help him.

I have no doubt that you can perform great feats with your "geothermal experience", but I fail to see where that gives you license to comment on me or my attempts to help other homeowners.

Ok, help him.

Instead of making snarky comments about trees or worrying so much about me, why don't you help him?

I take it the answer is no.

As Joe (a well respected professional here) pointed out, you are not helping, despite your belief to the contrary.

I contribute when it doesn't get in the way of a solution.

For the benefit of homeowners posting here with geothermal problems, I will continue to point out that ICFHybrid has no experience whatsoever with geothermal, other than possibly receiving a few quotes.  He does a disservice to the people that come here for help.

To the OP, I apologize for temporarily hijacking your thread.

I'd like to help, but am having to wade through pages of conjecture by someone who's geo expertise comes from "shopping for one".

Klat...co,
Why don't you PM me your Email and we'll walk you through the troubleshoot.

Uh, Joe, one of the purposes of having open forums is that people get the benefit of having many different types of input into their question, and others, who may not be posting derive benefit from reading it as well. Taking it private pretty much derails that.

Normally I'd agree with keeping this out in the open but you are SERIOUSLY impeding progress here. It's like walking out for the mail and having a really eager puppy constantly running between my legs. The temptation to boot it out of the way is overwhelming...and I've succumbed!

Put another way, your signal to noise ratio is below minimum for the job at hand.

With luck Joe will work it out and post the solution free of red herrings about planting or pruning trees in January.
