I did not write the above. In fact I questioned it. Jones wrote it. > Home heating efficiency and cost can be much improved by using wells for >> thermal storage.

After drilling a an array of themistors and a heat source are lowered into the well to check for and map thermal drains, i.e aqufiers, which are bad. The piping is insulated in depths of the well where heat loss occurs. The operational piping goes down the well and returns. The rock and soil around the well is used for heat storage. There are also shallow horizontal versions involving pipe snaked under maybe 20 feet of soil and insulated on top, which in effect are soil/gravel heat "ponds". Regards, Horace Heffner
