All temperature throughout the year varies no matter what geographic area and climate you live in. That could mean anything from blazing summers that cool to chilly winters. Most people don't realize that the temperature below the ground stays mostly consistent all year long regardless of climate.
The ground below us is able to consistency maintain a higher rate of temperature consistency because of it absorbing 47% of energy provided by the sun (heat) as it hits the Earth's surface. Our geothermal systems are able to utilize this free alternative energy source with what’s called an earth loop, ultimately transferring this energy to provide your office or house with central heating and cooling.
When doing the opposite in cooling mode, the heating process is reversed – rather creating cool, conditioned air throughout the home. Instead of extracting the heat energy from the ground, the heat is extracted from the air in your house and either moved back into the earth loop, or used to preheat the water in your stored hot water tank.
During the heating cycle, a geothermal heat pump uses the earth loop described above, to extract heat from the ground. As the geothermal system pulls heat from the loop, it passes it through a conventional duct system as warm air. The same energy can also be used for a radiant (heated) floor system or domestic hot water heating.
Geothermal energy has been used for several decades to heat and air condition buildings, and during that time, these geothermal systems have been referenced as many different things. Some of the more well-known variations include geo-thermal, ground-water, ground-water assisted, ground-water-source, water-to-water, and geoexchange
