My sister-in-law Mari Whitney and her husband Dick installed a house sized unit at their house in Mason City and it saves them a bunch of money. But the payback is loooong.

The Foodbank Goes Green
One of the first 50 wells being drilled in October2014.
This fall work began on an estimated $850,000 geothermal
project that will help cut utility costs at the Foodbank’s 56,000 square
foot facility. The geothermal projectwill help heat and cool a portion of
the building.
50 wells were dug 200 feet deep in the open lawn on the east
side of the Foodbank’s Cook Street location to install a closed loop
geothermal heating and cooling system in the ground.
The system will use the earth as a heat source in the winter and
a heat sink in the summer, resulting in significantly lower energy
consumption.
