Its called a Water Furnace and provides both heating and cooling. We have four 200 foot wells with a closed loop system connected to a heat exchanger and compressor. We put it in when the house was built last year. Works best as an AC since incoming water temp is 59-60 F and getting chilled air from this is easy (and cheap).
