Homeowners all over North America have discovered the benefits of using the energy source in their own backyards to provide heating, cooling and hot water.  Geothermal heating and cooling systems, also known as GeoExchange systems, tap into the constant, moderate temperatures found a few feet below the surface of the earth, to offer the finest in home comfort conditioning.

The efficiency of a GeoExchange system is based on the fact that is uses a small amount of energy to capture and move a large amount of energy.  In a typical home 70% of the total energy bill comes from heating, cooling and hot water.  As a result, the greatest opportunity to reduce your energy costs is to improve the efficiency of your heating, cooling and hot water system by utilizing this "down to earth" technology.  And this energy source is free, renewable, clean and environmentally-friendly.

GeoExchange systems, manufactured by WaterFurnace International in Fort Wayne, Indiana capture this free energy from the earth by using a series of pipe (an earth loop) buried in the ground.  During the heating mode, a special fluid circulates through the pipe where heat energy is transferred from the found (the heat source) to the fluid and then to the GeoExchange unit located in the home, providing warm comfort to the structure.  Inside the home, the heat can be distributed through either a conventional duct system or a hydronic radiant heat system.

To provide air conditioning the process reverses.  Heat is removed from the home and transferred to the loop fluid.  As the warm fluid travels through the pipe in the earth, it is cooled.  In the cooling mode, the earth serves as a "heat sink", a place to deposit the heat removed from the home.

In addition to earth loops, GeoExchance systems can also use a pond, lake or use well water as the heat source or heat sink to provide heating and cooling comfort for the home.

As a bonus, a GeoExchange unit can provide some or all of your hot water at higher efficiencies, offering additional energy savings.  Using a simple connection to your water heater, the GeoExchance unit will delivery hot water to your water heater during the heating and cooling modes.  In fact, the heat removed from your home during the cooling is deposited into your water heater providing you with virtually free hot water.

A GeoExchange system can easily be installed in most homes - new or old, large or small.  With many sizes, configurations and options available, the system will be designed and installed to provide the homeowner with many years of reduced energy costs, enhanced comfort, safety and reliability - all from technology that's "down to earth".
