Geothermal Heating and Cooling Ways to Cut Your Bill

As you might expect, most geothermal systems are installed in new construction and on good-sized lots. This is not to say that retrofits aren’t a good idea, or that they’re unworkable. In many cases they work well. Even modest city lots can often accommodate vertical loops. The problem is that most furnaces and air conditioners are replaced when they fail or when a real estate transaction requires it.

The water heat exchange will have to be installed and replace the current central heat and air system. Subsoil temperatures range from the low 40s in the North to the low 70s in the South. Of course, lower soil temperatures will reduce heating efficiencies and warmer soil will cut into air-conditioning savings. On average, however, ground-source heat pumps deliver three to four times the energy they consume. With a geothermal system – also called geo-exchange systems – a reasonably tight 2000-sq.-ft. home can be heated and cooled for about $1 a day.

Adding one of these to your geothermal system will add greater cooling in the summer, that is, if you have a body of water available. See the video below for more information.
