He suggested that a supercontinent he called Pangaea had existed in the past, broke up starting 200 million years ago, and that the pieces drifted to their present positions.
Geothermal heating system price varies depending on the type of loop system, usually either vertical or horizontal. On average, a typical home of 2500 square feet, with a heating load of 60,000 BTU and a cooling load of 60,000 BTU will cost between $20,000 to $25,000 to install.
Homeowners can now receive a federal tax incentive equal to 30% the cost of a qualified geothermal heat pump system. See our System Pricing for more information.
