the october bill is the only month we did not heat or use the ac, so i am assuming that is my normal electric use...$ 145..
the second column is extra cost to heat/cool, not counting xmas lights and the extra time we use lights because of the shorter days during winter.
525 dollars to heat with geothermal.....payback is every year
the coldest the incoming water temperature that i recorded was 38 degrees in march. it is back up to 45 degrees as of yesterday
this is my experience with geothermal...not what i have read or someone has told me about
