I am very interested in a DX system and have found the following 4 DX manufacturers sites online. To-date have spoken to reps from 1 of them. I would love to hear from anyone who has experiances with any of these companies.
ECR technologies based in Florida ( ECRtech.com)
ECR industries ( Advanced Geothermal) ( advgeo.com)
Earthsource energy solutions (American Geothermal(AMGEO.com)
Nordic ( Nordicghp.com)
The first one, from what i can tell is somewhat of a pioneer and pretty big, unfortunatly, the one installation i did find, was a disaster and ended up in court. I would love to hear from anyone using this system. You can always have a bad installation and this may not be a bad system.
The second one is smaller, based in PA. I liked the sales rep and am meeting with him again this weekend. He has promised me many names of people that i can talk to that have it installed.
Earthsource, seems to be a third party company recommended by american geothermal Via link on their site. I have not spoken to these yet. Again, I would love to hear from anyone that has this system
Nordic - well from detailed posts and information here from one gentleman (thanks), it seems like a fantastic product, however the closest dealer is hundreds of miles from me. Unfortunatly i don't think its an option
As anyone who is researching this knows, its a challenging task. You are thinking about spending alot of money on something that you obvivously know should work, however there are alot of people that really don't understand the design or installation process. At this point, I firmly believe that a DX system is the way to go, however untill i determine which is the best system and find a good designer/installer, i am still on the fence.
