Geothermal Heat Pumps

Geothermal or Ground Source Heat Pumps are the same thing; their name is an indication of their source of heat which is from the ground or geothermal source.  These types of heat pumps are the most efficient system you can buy.  GSHP are 300%-450% efficient which means that for every dollar you spend in electricity you receive $3.00-$4.50 worth of heat.  This is accomplished by installing in the earth a loop piping system.  Water is circulated through the piping system and the heat pump.   There are several reasons the geothermal heat pump is the most efficient.

  • We size the geothermal heat pump to the winter load of the home at -10 degrees F for our area.
  • The geothermal heat pump will provide about 50% in the winter and nearly 100% in the summer of your hot water needs the second largest energy consuming device in your home.
  • Because even at design outdoor temps of -10 the ground is still providing 35-45 degree entering water temperatures to the heat pump.


With a GSHP the temperature above the ground has very little effect on the temperature below the ground.  The result is a heat pump which will provide a constant heat output and efficiency no matter what the outside temps are.


The earth loop is the source of heat, so it is vital to be adequately plugged into the earth.  Once this is accomplished a source of heat is available to efficiently heat our homes, domestic water, swimming pools, hot tubs, etc.  There are several ways to install earth loops.


Domestic Hot Water from your water heater is the second largest energy consuming demand in the home.  A GSHP will provide DHW at the same rate as heating your home.  See CPM Cost Per Million Btu’s of heat page for more details.  With a GSHP your DHW can also be heated with the heat pump.  Air to air heat pumps don't provide this option.


Because the GSHP is located inside your home the life expectancy is higher because it is NOT exposed to the outside weather like an air to air heat pumps are.
