| ALL THE COMFORTS OF HOME RIGHT OUT OF THE GROUND | |
| Geoexchange is a simple technology that uses the earth's renewable energy to provide high-efficiency heating and cooling. In winter, the system draws heat from the ground and transfers it to your home. In summer, it extracts heat from your home and transfers it to the ground. Hardware consists only of a heat pump connected to a series of small-diameter pipes buried underground. A water solutions circulating through the pipes carries heat between the ground and the heat pump. |  |
| THE BEST ENVIRONMENTAL CHOICE OUTDOORS AND IN | |
| There are many other reasons why geoexchange is your best choice for home heating and cooling. Chief among them: Minimal environmental impact. No one would ever guess there's a heating and cooling system in your yard. Geoexchange preserves the natural beauty of your property. The network of pipes can be hidden under your lawn, a garden, even your driveway. The geoexchange unit is also out of sight - housed inside, protected from the weather. The sealed pipes circulate water or a non-toxic solution of water and anti-freeze that never comes in contact with the earth. And, unlike traditional technologies such as gas, oil and propane, geoexchange produces no combustion or smoke. That helps lower greenhouse gases, carbon dioxide and sulfur dioxide emissions into the atmosphere, as well as pollution concerns over storage tanks in-ground. A properly installed loop system will include a special high-density pipe which is used extensively by the natural gas industry. All underground joints are thermally fused. A properly installed closed loop system is sealed and requires no maintenance and has a long life expectancy. (For more information on types of loop systems, refer to the Geofields tab on this website). Geoexchange systems significantly reduce our dependence on the earth's finite supply of fossil fuels, and help keep our blues skies blue. |

| THE HIGHEST EFFICIENCY OF ANY HVAC SYSTEM | ||
|
There isn't a single more efficient HVAC technology than geoexchange. Oil and gas systems require fuel for heat and a separate air conditioning system cooling. Geoexchange provides both in one system. The EPA confirmed the superior efficiency of geoexchange, finding that even on a source fuel basis - accounting for all losses in the fuel cycle including electricity generation at power plants - geoexchange systems average 40% greater efficiency than air source heat pumps, 48% greater efficiency than gas furnaces, and 75% higher efficiency than oil furnaces. Today's best geoexchange systems outperform the best gas technology, gas heat pumps, by an average of 36% in the heating cycle and 43% in the cooling cycle. |

GEOFIELDS TYPICAL GEOLOOP SYSTEMS |
||
| Horizontal Loops |
|
|
| Horizontal Loops are installed in areas where the soil conditions allow for economical excavation. Taking up more land area than any other loop type, they are used where space permits. Trenches are normally 5 feet deep. Normally, several hundred feet of trench is required. | ||
| Vertical Loops |
|
|
| Vertical Loops are used extensively where land area is limited. A pair of pipes with a special U-Bend assembly at the bottom are inserted into a bore hole that averages between 150 to 250 feet in depth per ton of equipment. | ||
| Lake Loops |
|
|
| Lake Loops are usually very economical to install. If a pond or lake at least 8 feet deep is available, lake loops can utilize the water (rather than soil) for heat transfer. Reduced installation costs are characteristic of this type of loop system. | ||
| Open Loop |
|
|
| Open Loop installations actually pump water from an underground aquifer through the geothermal unit and then discharge that water to a drainage ditch or pond. Discharging water to a pond or lake is considered ideal. | ||
