Ground Source Heat Pump

Save year-round with a Ground Source Heat Pump.

A ground source heat pump (GSHP) unit is the most efficient heating system available, at 300 percent efficiency, and is ideal for today’s energy-efficient homes. A ground source heat pump system, which transfers heat to or from the ground, provides 100 percent of your home’s heating and cooling requirements.

How Does a GSHP and Cooling System Work?

• A water and antifreeze solution is circulated through a series of plastic pipes, called ground loops, that are buried four to six feet beneath the ground.
• The ground loops provide a renewable and reliable source of energy, as underground temperatures remain stable.
• Heat pumps use a typical refrigeration system to extract heat from the ground loops by changing the temperature, then circulating heat through standard ductwork. The system simply reverses during the summer to provide air conditioning.

Why Install a GSHP and Cooling System?

While the initial costs of purchase and installation are high, a ground source heat pump system is less expensive to operate than a conventional air conditioning system. The system saves $200-$400 each year over natural gas (based on 70¢ per therm)* and $700-$1,000 each year over LP (based on $1.40 per therm).*
