HEATING AND COOLING WITH GEOTHERMAL

KNOW THE FACTS

Traditional air conditioning or air source heat pumps have an outside condensing unit to expel or gain heat from the air.  Geothermal units do not have an outside unit.  Geothermal heat pumps are connected  to a piping loop system in the ground that rejects heat or collects heat from the ground which is a constant 57degrees.  The small difference from the ground temperature to the indoor comfort level thus requires very little energy.   If you keep your house 70 degrees, that is only a 13 degree difference.   On a traditional system if you keep your house 70 and it is 40 degrees outside, there is a 30 degree difference thus costing more energy.
