What makes = a=20 geothermal system different from conventional=20 systems?
A geothermal system utilizes the = energy=20 from the sun, which is stored in the earth, to = heat and=20 cool homes and buildings. Typically, electric = power is=20 used only to operate the unit’s fan, compressor = and=20 pump. So, unlike conventional systems, = geothermal=20 systems do not burn fossil fuel to generate = heat–they=20 simply transfer heat to and from the earth.
