    Great, can't complain about numbers like that.

    You mentioned that the three trenches you dug were 7 feet deep.
    What was the width and length of those trenches?

    Do you recall what make and model mini-excavator you rented?

    If I understand correctly, at the house, because your manifold is inside, do your three trenches begin at the basement wall?
    (or do you run the lines out so many feet to their individual trenches where the slinky loops begin)

    34" wide was the biggest bucket I could get.

    It was a John deere 35G mini excavator

    The slinkys have tails that all 3 tails went into 1 trench to the basement wall. I was careful to make sure all the loops stayed the same length. So the farthest slinky has less slinky and more tail then the closest. That way flow stays the same through all the loops.

    MW, insulate for 10' off your foundation.

    I haven't been on here in a while thought I would report no problems so far. Normal electric bills. Very please with the system so far.

    Just started cooling.

    The yard has some settling I'm planing on having filled in soon.

    Just got a lp contract offer in the mail and laughed. ;)
     
  7. Congrats! Nice job man!

    I was curious about what this year would bring for loop temperature after long periods of cooling.

    Last year I saw 90* and was a bit concerned. I now think this was due to the dirt not fully settled around the pipes.
    My trenches sank in about 18" took 42 yards of black dirt to fill it back in!

    So far cooling is working great! Nice and comfortable. Pulls humidity like it needs to. And the highest loop Temps I have seen are 68* during a long run in stage 2.

    Typically runs around 64-65* in cooling this summer.

    Looks like the system is doing very well.
    I still want to add data logging to the system just haven't had a lot of time to sit down and plan it and get it ordered!

    Good year for a test run in cooling.

    Nice to hear.
