FOR IMMEDIETE RELEASE: Turbo Charge Your Ground Source Heat Pump with an Amasond System! AMASOND, the designer & manufacturer of the new generation GeoExchange ground collector system in Austria, introduces their product for the North American market. The Amasond System will be unveiled at the IGSHPA Conference and Expo in Dallas TX on October 21 & 22, 2009. Centennial, Colorado September 15, 2009

what a joke !!

Ditto DD

Not sure what they are talking about, and looking at there website isn't much help, it's all written in German with no toggle button to switch to English.

I looked at the website with a webpage translator and I have a better understanding what they are taking about.  Basically they were using one pipe for a closed loop system, it's a pipe within a pipe so that the external pipe water is then forced into the internal pipe at the end of the line. Also with the use of special modules they can have a line T off to into a short drilled hole and return to the main line when it reaches the end of the pipe.

So you could have a trench just below the frost line, figure 2 feet deep, then drill short 6 foot holes along the trench. The pipe would run down the 2 foot tench, and at each bole hole a line would drop into it. Thus instead of digging a massive 6 foot deep, 4 foot wide trench, for a closed loop system, you can get by with a two foot trench with a number of short bore holes along it. The trench wouldn't have to form a loop for the return, since the return in inside the pipe.  The website wasn't pacific with bore hole depths, but I'm not sure 6 feet is what they mean, but I beleive I have the overall theory down pat. 

Why is this any better than how it's done now? A lot less digging would be involved, With a backhoe with a bore attachment, a trench could be quickly dug and the bore holes could be dug without the need for a drilling rig.  Actually a 6 or 12 inch wide trench would be Sufficent and bore hole just big enough in daimeter to easily push the pipe branch into it.  (I.E. quicker, Cheaper install) They also claim that the warmed water returning to the heat pump would help heat up the colder water leaving the heat pump, since the pipes are together. 

What do I think?  The piping kind of reminds me of a Sprinkler system piping, with all the coupling, I cant help to think that a leak wouldn't develop somewhere along the line over time, where as current closed loop installs tend to be one line that had no breaks in the line (or very few) underground.  It would make less of a mess of the yard installing the loop and the install time would be faster, but there are not massive saving here.  The digging of the trenches is going to be one of the least expensive costs of a Geothermal install overall. 

Actually taking another look at the website, they mention 40 meters as a maximun depth for the "Probes" as they call the T off sections. How are pipes inserted into drill holes now? I thought they use a looped pipe, but without somekind of coupler at the end of the line, wouldn't it get kinked just like a garden hose?       

I commend you for your interest in this new generation ground loop system. All the English information, website, specs, designed software etc, will be available for IGSHPA conference and exhibit in Dallas Texas. You almost got it... If you need further information, please send an e-mail to [email protected] Unfortunately this forum is missing the point if someone talks about new inventions that supports green building.

As soon as the website is in English, I will be interested. I don't care how many car parts the guy has made.

Seems like a ground loop that can transfer heat more efficiently than a standard HDPE might still be limited by the heat transfer rate of soil around it. Am I mistaken?

Exactly right Joe. The ground will only absorb or reject so much heat. The same ground is around these "experimental loops" as round the HDPE pipe, and copper loops. I know they all say they have different amounts of pipe/ton, try to a point, but dirt is still dirt...

...and there is simply no getting 'round the thermodynamic requirement to be in contact with a lot of dirt

Well they got one buyer......

There are a few youtube videos in English that show the system. Coaxial systems are used a lot in Europe with good efficiency.

My Google can't find any current AMASOND corporate web presence, in N. America or Europe.
Except for one "authorized installer"/contractor in Centennial Colorado, the entire operation has
apparently been "disappeared" ...by Exxon-Mobil, no doubt.

I was told that they were bought up- dunno who by.
