dx geothermal problems

Sounds like you might havean older EarthLinked DX geothermal system. The manifold sits about 6 feet below grade. I have a U.S. Power DX Geothermal system , installed in 1992, and having problems with the compressor and accumulator tank icing. The guy laughed and said they would pick it up and "See if the next guy would do this for you" and hung up on me! I want the most efficient one because I assume that these all will use more power than my old Geo. That may reducecosts if only 1-borehole is defective.

However, certain types of acids in the soil can effect the life of the copper. Our own system is a Nordic DX-45. Coated copper or cathodic protection are other viable safety measures. google_ad_width = 468; How many tons is your system;what configuration of ground loop? Earthlink uses "impressed current" cathodic protection that continually bombards the copper loop with electrons, not a sacrificial anode cathodic protection. So I have been looking at the big ones out there like York, Trane, Lennox and others. Manufacturer's recommend that soils be checked for high concentrations of acids, chlorides, hydrogen sulfide, sulfates or ammonia; these are to be avoided because of the potential for corrosion. DX boreholes are pressure-filled with grout (typical grout mixture consists of Type 2 cement, #30 fine silica sand, sodium bentonite, Superplastisizer and water is mixed using a chem-grout piston pressure pump or something similar.). Geothermal heat pumps are one of the green technologies capable of solving the problem of global warming by reducing carbon emissions. Was nitrogen usedduring this process? It's not an Earthlinked system, but from the company that Earthlinked spun off of, so they systems were identical back them. Before installing the loop, the dealer or contractor should do a soil test to determine the acidity of the soil and if measures are required to protect against acidity. I am not sure the other half is at this point, but something positive like you post may give us hope. Elmer, We have a 10.5 KWh solar array that creates 100% of our electric demand. They never reached out to us saying they had a need for the portable or I would have given it up. The pressure held perfect to the tee and there was also no signs of oil anywhere. Refrigerant is an inert gas - it does not, cannot cause electrolysis, so it won't corrode from the inside.

It seems like we are going to have to abandon the old system and go with an air sourced heat pump. Misinformation and rumours are in no short supply. I would suggest contacting themanufacturer directly for support.

I have reached out to the manufacturer to give us an estimate on the cost of excavating, testing and possible repair.

Cam home and the house was 81 degrees. Why is this furnace filter still clean after almost 1 year? I understand that Earthlinked has moved a little more forward than the manufacturer of my system, who did the initial install. The cutting edge of DX geothermal is using "green" refrigerants such as R744 (CO2). He is willing to give me the other owners contact info to confirm. Either no one is willing, able or cares to help us out. I’d verify themanifold and its welds to see if it’s the source of the problem. Why don't you start by telling us anything that was ever done to the system. We'll try to set the record straight. The DX geothermal heating & cooling system is considered the most advanced geothermal design available because it does not use water or a plastic ground loop. Areyou the original owner? Living in south eastern PA I don't know the exact PH of the soil. Houzzers Say: Top Dream Kitchen Must-Haves. I wold consider an EarthLinked DX system, but who is to say that this couldn't happen over again? Some details you requested. They had nicely given us a "loaner" portable AC unit to get us through. If you don’t understand passive design, you could be throwing money out the window, Mechanical ventilation can actually be better for your home than the natural kind. I was referred to another that I had a nice convo with yet has not sent a quote. I have a U.S. Power DX Geothermal system , installed in 1992, and having problems with the compressor and accumulator tank icing.
