See Gerald Seyler's video about his geothermal experience.
He had become interested in geothermal after first trying out one of the early air source heat pumps. They provided effective cooling and heating in small dwellings, especially during above-zero weather.
He had learned that geothermal heat pumps were even more efficient, and could be connected to existing wells used for drinking water. They paired a Climatemaster geothermal heat pump with their well, which is 213 feet deep, and for many years it provided 100% of heating and cooling for an 1800 square foot home.
