    saved is spent or spent is saved...you decide.

    We all have various experiences but scaling and clogging are only a few of the water quality problems. Hydrogen sulfide...big problem. PH...big problem. My 15 year $12,000.00 investment...down the drain (no pun intended) in 3 years and what installer wants get that bill. Mine doesn't. Water is not always constant either. Installers don't always follow the rules either so be careful.

    Eric: Thanks for the reply. I did go open loop and it has been running for about 4 months. I am keeping a close watch on the performance of the unit through the measurement ports and expect to clean it out annually. I did have the water tested before pulling the trigger. It was not as bad as I expected. I also kept the install cost down by doing all the plumbing and electrical myself. I paid a contractor for the unit and ductwork to hook it up.

    I built a system for my home in 1980, used a shell and tube condensor with removable end bells on the water side. It's on Long Island and the ground water will turn your sidewalks brown if you use it in a sprinkler system.

    Pulled the end bells once about 10 years ago and the only deposits I found where in the end bell gasket passages between tubes, the tubes where still clean.

    It,s still runing today, has had 1 compressor replacment and 1 well pump replacment (shallow well jet pump). Both the original compressor and well pump were used when installed and still ran 15 to 18 years before replacment.

    This thing runs great, has no restance heat as it never looses efficenty with the incoming water around 58 degrees year round.

    The house it's in is now owned by my Ex Wife but I still get to visit once in a while (the heat pump not the Ex )

    What type of well and pump are you using, I had a 30 foot stainless steel point driven well and it did bring up some sand that was caught in the inlet strainer the first year it ran but has been clean since.

    Pump and Dump

    I know very little about geothermal and am having my own problems but as a licensed wather operator I know a bit about wells. I chose not to use the pump and dump for several reasons.

    1. you never know the water in a well and I've had wells within 1 mile be very different. Water quality can ruin everything.
    2. If you use one well in a pump and dump think about this. Water in a well in a drought can drop in a well considerably. I've seen the water drop 80 feet in a well. This could cause a sort of short circuit in the water collum.
    3. more cost due to pumping instead of circulating.

    jongig: I agree there can be some serious drawbacks to a pump and dump arrangement, but in certain circumstances I think it can be very effective. We have an abundance of water (high water table right next to a blueberry field) and very sandy soil that readily returns water. The well was tested and could deliver 30GPM (way more than I need) indefinitely.

    Also, your comment about pumping costs increasing versus circulating costs ignores that open loop arrangements are more efficient. ClimateMaster's own literature gives significantly better efficiencies for open loop versus closed loop.

    kevin1955: I don't have my well specs in front of me except that I know it is ~50 ft with a 1HP submersible pump.
