Geothermal is our next big step. I have designed our system and we are saving for drilling the wells. In our area there is too much rock to lay horizontal loops for geothermal, so we use vertical wells. In my case, I need two 350 foot deep wells, which will cost about $15,000. The geothermal equipment will be less than $10,000 and I will do everything but the well drilling myself.
