I'm a firm believer in geothermal heat pump systems. So simple, yet so complicated. My uncle installed one of these systems in his house when he built it in 1975. The reason that these systems are not popular is:

Natural gas and propane providers offer incentives to builders to build houses that use their products. So, the builder gets a $600.00 kickback from a gas provider or spends $3,000.00 more to install a G/T system as they build the house. Want to take a guess which choice is made?
