In Dexter, Ann Arbor, and surrounding areas in SE Michigan summer temperatures can get very warm while the winter season often brings frigid temperatures. Those curious about geothermal installation and why this type of system is a good choice will find the following information enlightening.
Because the ground absorbs about 47% of the sun’s heat (energy), it is capable of sustaining consistent temperatures year round, regardless of the season. Using an earth loop, geothermal systems can tap into this free energy! During cold winter months, the earth loop on the heat pump extracts heat from the ground, circulating it through a conventional duct system. During hot summer months, the process is reversed wherein heat is extracted from the air in your home. This heat may be used to preheat water in your hot water tank, or cycled back into the earth loop. You only have to go about four to six feet below the ground’s surface to find temperatures that stay consistent all year.
