Dear Mr. Lusker, thanks for your support, however, unlike you, I do not think it was funny at all. Presumptuous, arrogant – no questions about that, - but clearly not funny. True in some cases,...

kenney t, trey r, Pascone10.

I could have responded to all of you in kind but I consider that it would be beneath me and in addition it would be a total waste of my precious time. Therefore I will...

Hmm..a little bit presumptuous and arrogant, aren't we. Let's see what I did during last 30 years of my life with my own hands:

- Completely remodeled my house, finished basement and build extra...

So having Master degrees in Geophysics & Computer Information Science will not be sufficient to qualify for the pro member on your board? Right?

LOL... What's wrong with my attitude? Did I offend anybody here by speaking the truth? So, should I be "politically correct" even discussing things of technical nature? Should we turn the science...

Hmm…very interesting and provocative thought, though I was not aware that "banning" was such a serious systemic problem. And if it is indeed reached those levels, I would like to know why people are...

O--h--h--h….Great Almighty, inquiring minds will be patient but they still have couple burning questions. Why those minds (and some of them have pretty good heads on their shoulders with extensive...

Who said it is. Are you going to use poly pipe for heat exchanger too????

First of all, what was the depth of the wells? Secondly, what is the composition of your soil? Thirdly, how much mess he created drilling those holes? And lastly what he was charging you per foot?

Ok, Mr. Admin. How about providing participants with ability to filter / ignore the whole thread / topic. It is much more effective and selective method than putting specific user on the "ignore"...

I never implied that in my post, I am only stating that healthy dose of all posts here deal with questions about systems in one shape form or another. As far as I am concerned those threads are...

Happy New Year. Do you think it would be beneficial for everybody to allocate a different group where all the posts of various systems pro's and con's would be discussed, nothing else? Would it make...

No doubts, the safest approach among all of them (though, not necessarily the most energy efficient one, but who is measuring...).

Though, as I said earlier, there are many variants in a closed...

I do not think that it makes much of a difference as long as they come from a well know maker. There are several major manufactures and they all operate with the same technology and use the same...

And how do you figure out temp change in your heat sink (earth, in your case). Let's assume summer (A/C cycle) in hot humid climate. Did you run calculations of projected temperature rise in...

Hey, sktn77a, still waiting. What's the problem?

Ok guys. I appreciate all responses and multiple lectures about comparative fuel cost and to tell you the truth, I can give those lectures myself. I never asked about that because I clearly...

Dear Perfectionist, thanks for the advice. I do not think I'll be able to find the right person for what I'm planning to do and I painfully realize the challenges and safety issues involved.

I'm...

Thanks for your kind response. Let's forget the rates for the time being, I would like to understand the project complexity.

I am not sure if it was even discussed in this shape and form but I was wondering how difficult would it be to customise existing natural gas furnace by adding electric heat element. So, in other...

Ok, I give up and for all of you who consider "high energy" prices are good for us in a long run and who do not get that it was all artificial manipulation, read up on this...

And this too...http://txspace.tamu.edu/bitstream/handle/1969.1/6246/ESL-IC-07-11-04.pdf?sequence=1

This may shed some light http://www.achrnews.com/CDA/Articles/Technical/8feb3c885a7bc010VgnVCM100000f932a8c0____

Really??!! So all scientific and technological developments in photovoltaic, nuclear physics, wind energy, real geothermal (take Iceland, for instance) and numerous other disciplines were driven by...

As I said before, it does matter I am not even sure how to respond to you as it appears that you do not understand that the energy futures market should have nothing to do with the actual spot market...

Thanks for bringing this subject because I was tormented by the very same questions for a LONG LONG time. First of all, I was also considering reverse cycle during heating season, especially during...

Is anybody here aware of efficient and cost effective NG emergency/standby generator on the market? We have been through periods of 6-17 hours without power, however running those cheap (up to $4000)...

I was looking all over and could not find any answers to the questions below, so if there is anything you could offer me, I would be extremely grateful for your wisdom and knowledge.

Q1. Let's...

What do you mean.." it doesn't matter'.. It does matter. Whatever those thieves objectives and motives are affecting our wallets. Do you understand that there is a huge difference between the actual...

First of all, I would like to know where you getting your numbers, secondly oil trading prices are pure fiction and virtual reality . Those prices have nothing to do with underlying oil economic...

Why? NG futures are currently trading below $4 and that is pretty low historically..

I just checked NG prices for the 3 coldest months here and I was right, delivered price is 0.70-0.80 cents per therm. It was much worse last year when Wall Street crooks were pushing Oil and NG...

There are other factors involved to make intelligent decision, like low energy consumption air handler. I do not believe it is available for NG furnaces with less than 90% AFU.

Absolutely, no question about it, however I am questioning your NG prices. I am not sure that those prices reflect your reality, - they are way too high and totally out of whack with Mdwest, for...

Ok, thanks for clarification.




So, can I figure out losses on return air? Is there a formula or relationship between duct configuration / duct geometry and air velocity (should I be concerned...

Unfortunately, in our case NG prices are changing monthly but plugging in even highest prices, it appears that running 3 COP HP is still not worth extra money you have to pay to have that option for...

Hi, Darrel. I do not get it and I am, quite frankly lost here. You are comfortable with 400 square inches for 3.5 ton unit while here in the same thread "jimj" sets it to 700 square inches. He is...

Thanks for your numbers, it's very good benchmark. Much appreciated.

The reason I did not post anything is simple. First of all our gas rates vary and swing wildly (obviously, they are highest when it is cold and /or Wall Street crooks are running those NG futures...

I think it will a waste of time because spending almost 3 hours of "googling" yesterday did not yield anything good. However, I am still in a shock after you presented me with your numbers yesterday....

Sorry, I did not realize that it was against the rules. Anyway, could you tell me what those companies are? Do you think that I'll be able to get an honest picture from them as far as the performance...

Yeep, it is very close. I thought that they are only available for commercial use and are cost prohibitive. Do you have any idea on their price?

Our gas rates are lower that is why I did not post anything. I am still shocked, how is that COP of 3 and above can't compete with COP of 0.95 under existing fuel cost. My only answer to that is to...

Well..well..well.. I am stunned and speechless…you just killed it right there. If you are telling me that with COP of 3 and above (assuming 40+ degree day/night) it will cost me about the same...

This is very serious post and before I attempt to respond, I would like you to clarify for me couple things and assumptions.

First of all, why are you talking about defrost cycles. I was under...

Ok, in our case it is very easy, though I am not sure how other electric utilities bill their customers. We have 2 tier rates (summer and winter). My point is that it is much more difficult to do...

With all due respect, I strongly disagree. First of all these systems are not for Wal-Mart or K-Mat / Sears shoppers (again, no offenses are intended or implied) and usually targeted market is pretty...

I am sorry but I do not get it. This does not make any sense, - if the objective of the high end units to save money how then that such obvious and integral option is not part of the “system...

Thanks, so is there a software where you can plug in relevant data (i.e. both units specs, energy cost and other data) to determine what unit to run?

Wow,.. thanks a lot. Did not expect the answer so quickly. Are u a contractor?
