How Geothermal Works No matter what climate you live in, the temperature throughout the year varies. For some climates that means hot summers that cool to ice-cold winters, and Burlington is no exception. What many people don't understand is that the temperature underground (regardless of climate or season) stays fairly consistent all year. The ground is able to maintain a higher rate of constant temperature because it takes in 47% of the sun's energy (heat) as it impacts the Earth's surface. Our geothermal systems are able to draw from this free energy with an earth loop. This technology is then put to use to provide your home or office with central heating and cooling. Geothermal Heating Utilizing the earth loop, a geothermal heat pump takes the heat from the ground in the heating cycle. The geothermal system sucks the heat from the loops and distributes this warmed air through a conventional duct system. Additional options include using that same heat to provide hot water and radiant floor heating are available. Geothermal Cooling The heating process is reversed in the cooling mode - creating cold, conditioned air all through the home. Instead of pulling heat from the ground, heat is taken 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.
