German climatologist and geophysicist who, in 1915, published as expanded version of his 1912 book The Origin of Continents and Oceans. This work was one of the first to suggest continental drift and plate tectonics. 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.
The base warranty for most HVAC systems is 5 years with the heat exchanger warrantied for 10 years. A registered limited warranty effectively doubles the length of warranty to 10 and 20 years respectively.ther Heating & Cooling System Factors. 1  Geothermal heating & cooling ($4,500 - $6,000) : Considered an eco-friendly heating and cooling option, these systems use energy in the earth to pump heat into a home. 2  It uses equipment that goes into the earth's crust and pulls heat out into a home.
