Geothermal Heating & Cooling
SAVE 60% FROM YOUR UTILITY BILLS.
Q: What is a geothermal system?
A few feet beneath the surface, the earth’s temperature remains constant. Geothermal systems take advantage of this constant temperature to provide very efficient heating and cooling.
In winter, a water solution circulating through pipes buried in the ground absorbs heat from the earth and carries it to the Geothermal System. Inside the building, a heat pump concentrates earth’s natural warmth, and then circulates it throughout the home using standard duct-work.
In the summer, the process is reversed in geothermal technology: heat is extracted from the air in the building and transferred through the heat pump to the ground loop piping. The water solution in the ground loop then carries the excess heat back to the earth. The only external energy needed for the Geothermal System is the small amount of electricity needed to operate the ground loop pump, fan, and compressor.
Q: Any Environmental Benefits?
According to data supplied by the U.S. Department of Energy and USEPA, a typical 3-ton residential geothermal system produces an average of about one pound less CO2 per hour of use than a conventional system. To put that in perspective, if just 100,000 homes were converted to geothermal, the country could reduce its CO2 emissions by 880,000,000 lb.That would be the equivalent of converting about 58,700 cars to zero-emission vehicles, or planting more than 120,000 acres of trees.In addition, the Geothermal System recycles the heat removed from the building during the cooling season and uses it to produce hot water. As a result, you will see a savings in hot water costs of about 30% to 50% annually.
Q: Commercial Applications?
While many homes have been fitted with Geothermal Systems, commercial enterprises (including factories, retail stores, office buildings, towns, and schools) also use geothermal to save energy and protect the environment. In fact, there are more than half a million installations in the United States today.According to the EPA, schools are a particularly attractive place for the use of this technology. Across the country, schools using geothermal right now are saving an estimated $25,000,000 in energy costs which can be used instead for better educational equipment and more teachers. These schools also save a half-billion pounds of CO2 emission per year.Should all of the nation’s schools convert to geothermal, the EPA has estimated that we could reduce oil imports by 61 million barrels annually, and provide the same environmental benefits of planting 8 million acres of trees or converting nearly 4 million cars to zero-emissions vehicles.
If the same comparison were made across all commercial and residential segments, the potential for environmental benefit would be staggering.
GI4™ HEAT EXCHANGER
The Gi4™ was scientifically designed through the collaborative efforts between Geothermal Innovations and Tennessee University. The patented Gi4™ heat exchange design encompasses kidney shaped lobes to create a greater circumference providing greater thermal conductivity, i.e. the exchange of heat. The Gi4’s™ dynamic and intuitive design also offers a pressurized up-flow of water, which will decrease electrical costs specific to the pumping requirements of the heat exchanger. Due to the increased design efficiency, the Gi4™ will not only reduce the costly geothermal well-field installation figure by over 20%, it will also greatly decrease the geothermal well-field size by over 60% in comparison to the industry standard U-Bend heat exchanger.
Gi4™ Creates a significant marketplace advantage – the geothermal well-field cost can be reduced by 20%+ and the footprint by 60+%
Allows for geothermal in larger and/or landlocked buildings
District wide system can save an additional 30% of geothermal well-field costs
Allows for district-wide geothermal installations in downtowns, corporate, university, and heath care campuses
District wide system can save at least 30% of geothermal well-field costs.
Provides for unique financing opportunities
Tax credits/deductions/exemptions, depreciation, rebates, other subsidies and lowered geothermal well-field cost makes geothermal costs competitive with standard HVAC
