I'm picturing a Corsi-Rosenthal box with automotive radiators connected in series instead of air filters! The inlet hooked to a sink, and the outlet hooked to the drain. Heat losses would be introduced at the well's pump, and at the box fan motor. As long as nothing leaks, the only things to worry about would be the added power consumed, the added wear on the well pump, and the well water's rate of replenishment. Oh, and the condensation which may collect on the radiators. An interesting DIY idea. I wonder if anyone has already tried it.

    Sounds like you are combining both ideas somehow? The Corsi-Rosenthal box radiator in your sink would absolutely work. Though I don't know how much water you would be going through for it.

    If you instead used a closed loop and pumped water through the ground to cool off then the only thing going is the pump and fan.

    Condensation is a possible issue, tray and bucket to collect it?

    Hmm, let me elaborate. If I were to do it, I'd hook a hose up to the spigot on a basement sink. I've seen some that have external threads so one may connect a garden hose to it. I would then take my length of garden hose into a convenient space in the basement, perhaps one that helps maximise airflow or is close to a basement drain or some other available place. Then I would plumb the garden hose into the inlet of one of my radiators, and the outlet to the next inlet, and so on. As the relatively cool well water passes inside the radiators, my box fan draws warm humid air (almost 100% humidity on a dangerous wet-bulb day!) through the grilles of the radiators and exchanges some heat. In theory, the exhaust of the box fan/radiator assembly is now somewhat cooler and possibly drier. The now heated well water I would then plumb from the outlet of the final radiator to the sink so it could go down the drain. If the heated water were returned to the well, there are contamination issues as well as significantly more heat losses depending on the available water capacity and exchange rate of the well. Does this setup differ from what you had in mind?
