How does a geothermal system work?

Geothermal systems tap the relative warmth of the earth in the winter and the relative cool of the earth in the summer, providing both heating and air conditioning. Some electrical energy is used to gather heat in cold weather and dissipate it in warm weather, but this energy usage represents only a fraction of the overall heating and cooling power delivered to your home by the geothermal system.

Will the system still work in extremely cold and hot weather situations?

Yes. Even when outside air temperatures reach cold and hot extremes, the geothermal system will continue to function. The system relies on the relative temperature stability of the ground five or more feet under the surface, which averages 55 degrees and fluctuates between 45 and 70 degrees Fahrenheit. So, even when air temperatures are extreme, your geothermal system will be able to extract heat from the ground in the winter and shed heat in the summer.

How much more efficient are geothermal systems compared to conventional approaches?

Geothermal systems are highly efficient in both heating and cooling modes. Compared to traditional furnaces, geothermal systems are 50 to 70 percent more energy efficient. In cooling mode, geothermal systems are 20 to 40 percent more efficient than conventional air conditioners. These energy efficiencies translate directly into savings for homeowners on their monthly utility bills.

But isn’t a geothermal system going to cost a lot more?

Not in the long run. While the initial costs of geothermal systems are higher than conventional heating and air systems, owners can immediately enjoy positive cash flow on financed systems and recoup their investments in as few as four years. Of course, the savings to homeowners continue to add up long after the initial system costs have been covered.

How much money can I save with a geothermal system?

Monthly utility savings are significant for all homeowners, though exact totals depend on several factors, including the cost of energy, the size of the home as well as the age and function of the replaced systems. One example, cited in Forbes (June 4, 2007), projected a total 60-month savings of more than $21,000. When Geothermal Energy Solutions meets with a customer, we use the size of the house and other factors to provide the homeowner with a custom estimate of cost savings over time.

Is a geothermal system good for the environment?

Many people are increasingly concerned about the impact our overall energy usage and our continuing dependence on fossil fuels may be having on our environment and climate. Because geothermal systems are highly efficient and do not rely on the burning of heat fuel, they are particularly friendly to the environment. In fact, a recent study by the Environmental Protection Agency (EPA) confirmed that geothermal systems have the lowest environmental impact of various approaches to heating and cooling.

What other advantages do geothermal systems offer?

In addition to reducing your utility costs and lowering your home’s environmental impact, geothermal systems also deliver exceptional year-round comfort, helping eliminate the hot and cold spots that are typical with other approaches. In addition, geothermal systems enhance the resale value of installed homes and give would-be buyers added incentive to choose a geothermal-equipped home over otherwise comparable homes. Geothermal systems are also very quiet, long lasting and do not rely on exposed outside equipment, reducing the potential for related maintenance and repair.

Does geothermal represent a proven, well-established technology?

Yes. The basic principles behind modern geothermal systems have been used for more than 150 years, with many elements of current systems dating back about 30 years. As such, homeowners have been enjoying the benefits of geothermal systems for many years. Recent technical advancements have made new systems still more efficient and economically attractive to owners.

Are geothermal systems too good to be true?

Not at all. Modern geothermal systems are highly advantageous to homeowners, providing efficient and effective heating and cooling year-round while delivering substantial utility savings. Geothermal systems also reduce the environmental impact of installed homes, lowering the overall demand for energy created in conventional ways. Geothermal systems have been endorsed by the US Environmental Protection Agency (EPA), the US Department of Energy, and the California Energy Commission.
