A lot of our clients ask us, “How does geothermal work?”
We all know that Wilmington homes are subjected to varying temperatures throughout the year. Some climates can see the extremes that summer and winter throw at us. There is a consistent source of temperature that you can put to good use; just a few feet beneath the earth’s surface. How is that possible?
The sun infuses the Earth’s crust with its heat energy. Forty-seven percent of that energy is stored in the ground as heat. Bosch geothermal systems extract this heating potential using an earth loop system; collecting this free heat for your home. This innovative technology uses the sun’s heat that the earth has conveniently deposited to condition your home or office.
In the heating cycle, a Bosch geothermal heat pump employs the earth loop system to extract the heat from the ground. Delivery through a conventional duct system, the geothermal system pulls heat from the loops and distributes it as warm air. Options are available to use that same heating energy to provide hot water heating and radiant floor heat.
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.
