    I am building a new home with a Climatemaster closed loop geo unit. The pumps operating the fluid flow run very hot in the summer when a/c is on and frost up in the winter. My installer says this is normal. I am concerned that this is an indication of bigger problem. Comments please

    So, on a scale of 1 to 10, how hot is "very hot?"

    ...or maybe a scale of 32 to 212 ?

    If I hold my hand on the pump, my hand becomes warm immediately and very uncomfortable after a couple of minutes. I have not timed how long I could leave my hand on the pump before it is necessary for me to remove. On a scale of 1 to 10 I'd say it is a 7.

    I think Looby was kidding with the 1 to 10 scale

    a thermometer would be a better troubleshooting tool

    Do you have P/T ports? They usually have small brass caps that unscrew to allow probes, attached to thermometers and pressure gauges, to be inserted.

    Are you running the unit during construction?

    If you can keep your open palm on it for 20-30 seconds, it's below 130°F.
    Thus spake a salty old E8 MM shipmate from way, way back when...

    ...shortly before they invented thermometers,

    Climatemaster pump problem

    I convinced the installer that "everything is okay" and "we performed test when the unit was installed" is not very comforting to an owner who knows little of Geo closed loop system. The installer is coming out to preform those test. Any other test that I should insist he perform? I presume Climatemaster has some standards to compare against. And yes, the unit was operating during construction. Installer has replaced a filter already.

    If the tech is coming out anyway, why not do a complete once over and collect data. I have been slowly and reluctantly adding more data to my life, customer by customer.
    flow rate
    time of year
    outside temps
    inside thermostat setting average
    amp draw
    This now becomes part of a customers file.

    It would be helpful to know where this system lives

    Frosted loop lines in winter implies a fairly cold locale.

    If you can keep your bare hand on the pump for a minute or more it isn't too hot.

    Location and more precise temperatures would help us help you.
