REASONS TO CHOOSE GEOTHERMAL
Geothermal systems use a small amount of electricity to transfer heat to and from the ground to your home. In
fact, it can produce three to four units of energy for every unit of electricity used to power the system.  Even the
best ordinary system delivers less than one unit of energy for each unit it consumes.  Homeowners typically experience an annual savings of 30 to 70% when compared to ordinary systems. 

ENVIRONMENTALLY FRIENDLY:
Geothermal is recognized by the US Environmental Protection Agency as the most environmentally-safe, cost
effective heating and cooling system on the market.  Installing a geothermal system is equivalent to planting 750
trees or taking 2 cars off the road.

QUIET:
Geothermal systems use the same principles that operate a refrigerator or freezer, and the units are just as quiet.  There is no unsightly outdoor unit to disturb you or your neighbors.

COMFORT:
Geothermal systems heat and cool homes evenly, eliminating the hot and cold blasts of air found with conventional
systems.  Geothermal systems also dehumidify the air during hot summer months.

CLEAN AND SAFE:
Geothermal units do not use fossil fuels such as natural gas or propane.  Threats caused by combustion are eliminated. No worries about flames, fumes, odors, or carbon monoxide.

HOW GEOTHERMAL WORKS:
Your own backyard has the potential to be an energy source for heating and cooling comfort. Outdoor air temperatures fluctuate throughout the year with the changing seasons. In contrast, ground temperatures about four to six feet below the Earth's surface remain relatively moderate and constant all year. That's because the Earth absorbs 47% of all the heat energy that reaches it's surface from the sun. A geothermal system circulates a water-based solution through a buried loop system to take advantage of these constant temperatures. A single piece of equipment has the ability to heat and cool your home, while providing some or all of your home's hot water as well. Geothermal systems can save you 30% to 70% on your monthly utility bills.

HEATING CYCLE

During the heating cycle, the fluid circulates through the loop extracting heat from the ground. The heat energy is transferred to the geothermal unit. The unit compresses the extracted heat to a high temperature and delivers it to your home through a normal duct system or radiant heat system.

 COOLING CYCLE

For cooling, the process is simply reversed. Because the earth is much cooler than the air temperatures on a hot day, the geothermal system removes heat from the home and deposits it into the ground. The fluid is cooled by the ground temperatures and returned to the unit for cooling your home.
