Jack Strickland Heating & Air Conditioning Geothermal Energy
Homeowners across North America are searching for better ways to get more out of their energy dollar. Many are finding that Geothermal Heat Pumps can help.
Geothermal Systems are the worlds most advanced and most cost-efficient heating, ventilating and air-conditioning (HVAC) systems. The EPA has confirmed geothermal systems operate at 75% greater efficiency than oil furnaces, 48% greater efficiency than gas furnaces and 40% greater efficiency than air source heat pumps.
Geothermal energy costs significantly less to operate than any other heating and cooling system, but it also helps preserve our natural resources and lessens our dependency on fossil fuels.
How It Works
The steps below describe how a heat pump works in “heating mode”—taking heat from the ground and delivering it to a building—and “cooling mode,” which removes heat from the building and transfers it to the ground.
Circulation: The above-ground heat pump moves water or another fluid through a series of buried pipes or ground loops.
Heat absorption: As the fluid passes through the ground loop, it absorbs heat from the warmer soil, rock, or ground water around it.
Heat exchange and use: The heated fluid returns to the building where it used for useful purposes, such as space or water heating. The system uses a heat exchanger to transfer heat into the building’s existing air handling, distribution, and ventilation system, or with the addition of a desuperheater it can also heat domestic water.
Recirculation: Once the fluid transfers its heat to the building, it returns at a lower temperature to the ground loop to be heated again. This process is repeated, moving heat from one point to another for the user’s benefit and comfort.
Heat exchange and absorption: Water or another fluid absorbs heat from the air inside the building through a heat exchanger, which is the way a typical air conditioner works.
Circulation: The above-ground heat pump moves the heated fluid through a series of buried pipes or ground loops.
Heat discharge: As the heated fluid passes through the ground loop, it gives off heat to the relatively colder soil, rock, or ground water around it.
Recirculation: Once the fluid transfers its heat to the ground, the fluid returns at a lower temperature to the building, where it absorbs heat again. This process is repeated, moving heat from one point to another for the user’s benefit and comfort.
The above-ground heat pump is relatively inexpensive, with underground installation of ground loops (piping) accounting for most of the system’s cost. Heat pumps can support space heating and cooling needs in almost any part of the country, and they can also be used for domestic hot water applications. Increasing the capacity of the piping loops can scale this technology for larger buildings or locations where space heating and cooling, as well as water heating, may be needed for most of the year.
All geothermal heating and air systems qualify for a 30% tax credit. This covers all equipment and installation costs including drilling of the required wells, bringing installation costs in line with a high efficiency air to air system.
