Geothermal Exchange Cost Comparisons
Geothermal / Exchange Heating & Cooling
Mother Earth fortunately has many splendid characteristics. One of them happens to be the fact that the temperature of the subsoil about 5 to 10 feet below the surface remains fairly constant year-round. The temperature, once you get to this level, happens to be in the mid-fifties F. If you start to tunnel deep into the earth, the temperature actually starts to rise.
Traditional Heat Pumps
If you own a traditional heat pump, you know that they produce a cool heat. This is just how they operate. The limitation is due in part to the fact that an air transfer heat pump can only grab so much heat in a given amount of time from air that is 28 degrees! Traditional air transfer heat pumps are most efficient when the outdoor air temperature is around 55 degrees or so. Now isn't that convenient! Imagine if you could surround the heat pump refrigerant with 55 degree temperatures all of the time? That is exactly what you can do with a properly designed and installed geothermal / exchange heat pump system.
Great For Every Building
Geothermal systems are used in commercial applications, schools, and all sorts of different places other than homes. Those places that are blessed with lakes or large ponds really have it made. As long as the pond doesn't freeze solid during the winter months, you are golden! Think. When you jump into a pond or a lake and go fairly deep, the water is very cool - say in the 50 or 60 degree range. Well, there you go...... All you have to do is lay the geothermal loop on the bottom of the pond. It gets buried by water instead of dirt. What's more, the transfer of heat to and from the loop is nearly 100 percent efficient when surrounded by water.
