Many people take pride in maintaining their lawns and work hard to cultivate a thick, plush weed-free carpet of green to enjoy. Others see it as a playground for their children and pets, or as an extension of their home, working to create an inviting garden oasis to entertain their family and friends. How many of us, however, see our lawns as a constant, renewable source of heating, cooling and water heating for our homes? Well, this is what geothermal heating and cooling is all about.
When you install a geothermal heating and cooling system, you are actually putting your lawn to work for you, because it becomes a permanent power plant for your home. This type of a heating and cooling system is comfortable, reliable, energy efficient and even cost efficient to boot.
So, how does this powerhouse of a heating and cooling system work? Well, basically the earth absorbs almost 50% of all solar energy and, depending upon what geographic region you live in, maintains an almost constant temperature of 50°F to 70°F. A geothermal heating and cooling system is based upon an underground loop system which utilizes the earth’s constant temperature to exchange energy between your home and the earth as needed for heating and cooling.
So in the winter, water circulates in the underground loop system and absorbs heat from the earth, which is then carried to the geothermal unit. Here the heat is compressed to a higher temperature and is sent as warm air to your indoor system to be circulated through your house.
In the summer the geothermal system reverses and expels heat from your home into the cooler earth via the loop system. This is a natural cooling process and an efficient way to create a comfortable climate in your home.
A geothermal heating expert will be able to recommend the right loop system for your home contingent upon the characteristics of your property. A loop system can be vertical, horizontal or submerged in a nearby pond or lake; sometimes, a water well can also be used instead.
One of the advantages of a geothermal heating and cooling system is that your monthly utility bills will decrease. On average, the typical home can save in the range of $600 to $1200 annually. Another nice benefit is that geothermal heating and cooling helps to reduce greenhouse gas emissions.
If you’re considering replacing your heating and cooling system, contact a geothermal cooling expert for an estimate on installing this system in your home—and let your lawn go to work for you!
