How Does Geothermal Cooling Work?

We trumpet the values of geothermal cooling here simply because of all the benefits it provides. It draws on the ambient temperature of the earth itself, which is an infinitely renewable resource and consumes little energy. You need only pay for a small amount of electricity to run the rest of the system, which not only saves you money on monthly bills but helps you do your part to keep Mother Earth green and healthy. Understanding how geothermal cooling works can do a great deal as far as clarifying those benefits go.

Underground

Geothermal cooling systems are often expensive to install because you need to bury a length of the looped coil under the ground, which means construction equipment and manpower. There’s a reason for that. Once you dig down below 10 or 12 feet, the temperature in the Earth never changes no matter how hot or cold it gets above the surface: remaining steady at about 58 degrees. The system pumps a mixture of water and antifreeze through the coils, which facilitate a heat exchange with the ground. In the summer, it pulls heat from the air in your home and releases it into the ground, keeping you cool and comfortable without having to expend any fuel.

Who Benefits

Not every home can benefit from geothermal cooling and many will do quite well with more traditional forms of energy. Geothermal systems work well for home with an eye on the big picture: saving money over time in exchange for a larger up-front investment. You also need space: a larger piece of property tends to work best, though the coils can be installed vertically as well as horizontally. They usually benefit large houses too, which can use all the help they can get to keep air conditioning costs down.
