I am completly opposed to Air-conditions propagandized as a solution to climate change. What is the wright approach to combating this state of temporary relief except from old-fashioned fans? Don't get me wrong. They do the job for me. I am reffering to finding a solution for people more with health issues or large facilities that are in need of something more drastic.

Earth tubes could pump water instead of air and then pass it through a car radiator or similar kind of heat exchanger.

I find the idea interesting but haven't actually tried it. Could cost a bit and not sure how effective it would be.

    That's a buried coil closed heat pump system. Very expensive.

    CAN be very expensive. If you are doing it with a car radiator and a hose pipe it costs very little and there isn't even a heat pump involved.

    You can take it up a step by using a heat pump of course. Which you can also do fairly cheaply if you are willing to modify a portable AC unit or tbh anything else with a heat pump in it. All you need to do is water cool the hot side of the heat pump and send that water through your ground loop.

    Depends how much you want out of it. Are you heating and cooling the entire house year round along with providing hot water. Or are you just taking a few degrees off the peak summer temperature in a room or two?
