A geothermal system fills your home with warm air in the winter and cool air in the summer for a fraction of the cost of traditional heating and cooling solutions.

At the heart of the system is a heat pump, which moves thermal energy from one source to another.  These systems have been used successfully in moderate climates but New England weather is just too severe for heat pumps to work efficiently.  In fact, when the temperature falls below freezing, a heat pump won’t work at all.

A geothermal system makes up for this problem by providing water from the ground, which is always at a 52 degrees Fahrenheit.  At that temperature, a heat pump works very well.  In the winter, water is pulled from the ground and run through a mechanical system, where heat is extracted before the water returns to the ground at approximately 20 degrees Fahrenheit.  That heat is used to push warm air through the ductwork and into rooms.  Unlike an oil-fired forced hot air system, the warmth from a geothermal system does not dry out the home, causing damage to wood furniture or dry skin.

In the summer, the heat pump works in the reverse and water returns to the earth at 90 to 100 degrees while the home is cooled with just the right level of moisture so the body feels happy.

As if this wasn’t enough to sell you on the idea of geothermal, most homes can be cooled for $100 per summer instead of air conditioners that can cost $400 to $500 per month to run.

A 3,000 square foot home can be heated during a harsh winter for about $1,500 compared because a geothermal system is 70 percent more efficient than home heating oil and 80 percent more efficient than propane.

As with any system, maintenance is important but there is little to care for in a geothermal system.  A good practice is to replace filters twice a year and have a professional check up every two years.

Most geothermal systems last 25 years and have a proven record of accomplishment going back to 1940.  Rising fuel costs have been instrumental in making this type of heating and cooling more popular and your contractor can help you identify rebates and incentives to help pay for a new system whether you are building a new home or retrofitting your existing house.
