Geothermal heating and cooling

Geothermal Units Offer Cost-Effective Heating and Cooling

For many homeowners, the rising costs of heating and cooling their home have become almost too much to bear. Many homeowners are desperately searching for new ways to keep their home temperature regulated without the skyrocketing energy bills. Fortunately, many new and advanced technologies have emerged in recent years as individuals have become more interested in not just saving money, but also saving the earth. These environmentally friendly techniques have helped homeowners save thousands of dollars by utilizing one previously untapped resource: their own backyard.

While outdoor temperatures can fluctuate greatly, especially in four-season climates, underground temperatures generally remain consistent throughout the year. New geothermal systems are being placed in homes across the country to take advantage of this natural heating and cooling system that lies about four to six feet underground on any property. The system uses a water-based solution that circulates to bring the moderate underground temperatures into your home.

In comparison to conventional boilers and furnaces, geothermal heat is up to four times more efficient. During the heating cycle, the water-based solution is circulated through the system to extract the ground’s trapped heat. That heat is compressed to a high temperature and is then delivered into the home’s existing heating system, whether through ducts or radiant heat.

A similar process is used when the geothermal system cools a home during warmer months. During the cooling process, the geothermal pumps work in reverse to takes heat from the home and circulate backwards through the system so it can be absorbed into the ground. Once that fluid is cooled underground, it is brought back into the home for cooling purposes.

Significant energy savings can be seen from the first day of installation, and can provide continued savings throughout the year, since these systems also provide hot water in addition to heating and cooling services. Generally, homeowners see a 30% to 70% reduction in monthly costs for heating, hot water and cooling. These savings can have an immediate impact on your family and eventually pays for the cost of installation several times over.

Additional financial benefits are available to homeowners who decide to install a geothermal system on their property. In addition to lowered costs for energy bills, a geothermal system can have a significant increase on the value of your home. Also, when an Energy Star rated geothermal heat pumps is installed, the homeowner receives a 30% tax credit. Because they use natural resources and use only a fraction of the traditional amounts of energy needed to heat and cool a home, a geothermal system is both a cost-effective and environmentally friendly way to keep your home temperature regulated.

      Geothermal heating is a fabulous way to heat and cool your home. I can say this as I use to own a home in the country and it was heated and cooled with this system. Heat is instant and cool down in terms of air conditioning is instant (and freezing cold if you're not careful). If you can afford it, it is the best way to go!
