    Has anyone done a study on the effects massive input of heat and cooling into ground water from large development projects might have?

      The engineer in me wants to know how resilient the heat (or “cool”) capacity of the subsurface is.

      Invert the concept, and pretend you want to push a lot of heat into the ground. Will all of the heat being pulled out of those structures in the summer (24 hour average of temps ~90°F) end up increasing* the ambient temperature of their source rock?

      Much like a well drawing water out of an aquifer produces a “cone of depression” immediately around the well, would the rock surrounding the ground pipes develop a significant slow thermocline (such that there is a halo of extra heat around pipes trying to dump it into the ground).

    Just speculating here BUT most nuclear reactors would dump a lot more heat. My uncle preferred to cast his line near the outlet of Bruce Nuclear (Kincardine, Ontario, Canada) because that is where the fish liked to congregate.

    Now the question you asked involved a big scale operation but companies like WaterFurnance (Fort Wayne, Indiana) have been installing individual units in homes and business for more than 30 years.
