Summary: Geothermal heat pumps use the earth instead of air as their heat source and pump the heat of the earth into your house.
I have used air source heat pumps for over 30 years.
To me, it’s the very best way to heat & cool a home.
However, air source, or air to air heat pumps are limited to non-frigid climate.
Heat pump technology has advanced to the point where an air to air heat pump will operate in almost any climate…almost any climate.
For frigid climates there just isn’t enough warmth in the air during the (long) heating season.
When the temperatures drop into the low teens, or below, for days, weeks, and even months at a time, the gas (or electric) backup system in a heat pump comes on and stays on, driving up your utility bills and the energy savings attributes of heat pumps out the window.
But, what if you were able to use something besides air that you could use as a heat source, something that had constant warmth?
How about the earth?
Well, that’s what a Geothermal Heat Pump uses.
Geothermal heat pumps use the relatively constant temperature of the ground or water several feet below the earth’s surface as source of heating and cooling.
Geothermal heat pumps can be installed in existing homes and, besides heating and cooling, geothermal heat pumps can even provide domestic hot water.
They can be used for virtually any size home or lot in any region of the U.S.
