No matter what climate you live in, the temperature throughout the year varies. For some climates that means blazing summers that cool to frigid winters. What many people don’t realize is that the temperature below ground (regardless of climate or season) stays fairly consistent all year. The ground is able to maintain a higher rate of temperature consistency because it absorbs 47% of the suns energy (heat) as it hits the Earth’s surface. Geothermal systems are able to tap into this free energy with an earth loop. This technology is then used to provide your home or office with central heating and cooling.
During the heating cycle, a Geothermal heat pump uses the earth loop to extract heat from the ground. As the system pulls heat from the loop it distributes it through a conventional duct system as warm air. The same heat energy can also be used for a radiant floor system or domestic hot water heating.
In the cooling mode, the heating process is reversed – creating cool, conditioned air throughout the home. Instead of extracting heat from the ground, heat is extracted from the air in your home and either moved back into the earth loop, or used to preheat the water in your hot water tank.
Geothermal energy has been used to heat and air condition buildings for several decades, and during that time these geothermal systems have been called many different things. Some of the more popular variations include geo-thermal, geoexchange, ground-water, ground-water assisted, ground-water-source, water-to-water, & geothermal heating and cooling.
Benefits of Geothermal Heating and Cooling?
Learn about the benefits of Geothermal heating and cooling including the energy efficiencies, cost savings as well as the incentives that are available for those that install Geothermal systems into their homes. Read this Lincoln Journal Star column or view these great information videos to learn more about geothermal. Whether you are building a new home or replacing a system give geothermal some consideration. It may be the best solution for you!
How do Geothermal heating and cooling systems work? This video explains and also covers the different types of loop systems that are available.
