Exploring Geothermal Heating and Cooling

With people becoming more conscious of the environment, and wanting their dollars to go further, companies around the world are coming up with new technology to satisfy consumers. Enter Geothermal Heating and Cooling Systems. These systems are both environmentally friendly and have lower operating costs.

Geothermal Systems use the Earth to heat and cool air in the home using a series of pipes, called a loop, which is installed below the surface of the ground. During the winter, Earth’s natural heat is collected as fluid circulates through the loop. It is then carried into the house where an electrical compressor and heat exchanger concentrate the Earth’s energy and releases it inside the home at higher temperatures. In summer, the home is not cooled by blowing in cold air, but rather drawing the heat from inside the home and cycles through the loop where it is absorbed by the Earth.

These systems also produce much less greenhouse gases than air conditioners, oil furnaces, and electric heating. The US Environmental Protection Agency has called ground source heat pumps the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available. Further, geothermal heat pumps are durable and require little maintenance. The underground piping for the system is often guaranteed to last 25 to 50 years. And with no outside condensing units like air conditioners, they are quieter to operate.

All in all, geothermal heating and cooling is a good way to go. While the upfront cost may be a little more, the long term benefits make up for it. By using a renewable resource (the Earth’s heat) and lowering greenhouse gas emissions, there is a much smaller environmental footprint left behind.
