Geothermal Energy Facts

Geothermal technology has been providing energy efficient climate control solutions to homes and businesses for many years. Here are some Geothermal Heating & Cooling facts:

What is Geothermal Energy

  • Geothermal heating and cooling uses ground source energy- a form of renewable energy derived from heat deep in the earth’s crust.  For every 100 meters you move below ground, the ground temperature increases approximately 3 degrees Celsius.  Or, for every 328 feet you move deeper below ground, the temperature increases 5.4 degrees.
  •  Geothermal heating and cooling used in homes and buildings takes advantage of the abundant supply of natural and stable energy stored in the Earth.

How does Geothermal Energy Work in my Home or Business

  • Whether you have a horizontal, vertical, or lake closed-loop Geothermal system, your Geothermal heat pump is going to treat the earth as an energy reservoir for heating and cooling your home; during the hot Summer months, your geothermal system will remove the heat from your home or business and transfer that heat into the earth via your closed-loop system.  During the cold winter months, your geothermal heat pump will utilize your closed-loop system to take the heat energy stored within the earth and move it into your home or business.
  • Geothermal systems are extremely quiet. You don’t have an outdoor air conditioner that rattles or vibrates in the summer time when you are trying to enjoy the outdoors. The Heat pump is installed within your home or business, and operates quietly and efficiently to maintain a comfortable indoor climate.
  • Geothermal heating and air conditioning systems do not use fuel to run.  Geothermal heating is flameless and, therefore, produces no health and safety concerns that come with burning fossil fuels.  The US Department of Energy (DOE) along with the Environmental Protection Agency (EPA) have named geothermal systems the most environmentally friendly way to heat and cool your home.
  • Because geothermal heat pump systems are so efficient, much less energy is required to heat and cool your home or business.  This reduced energy requirement often means that less fossil fuels will be consumed to maintain a comfortable indoor climate.  The Environmental Protection Agency (EPA) estimates that geothermal systems can reduce energy consumption- and corresponding emissions- up to 44% compared to air-source heat pumps.  Furthermore, the EPA estimates up to 72% reduction in energy consumption when compared to electric resistance heating from standard HVAC equipment.

Advantages of Geothermal Energy – Geothermal Energy Pros and Cons

  • Geothermal Systems remain in operation for an average of 20-24 years. That is an average life cycle 5-11 years greater than Standard HVAC systems which typically last 13-15 years.  Unlike standard HVAC systems, Geothermal heating and cooling systems remain unaffected by seasonal temperature extremes because the earth surrounding the geothermal closed-loop system remains at a constant 55 degrees Fahrenheit regardless of whether the outdoor temperature is 100 degrees or 0 degrees.
  • Your Geothermal Heat Pump can use the heat taken out of your home to provide your home with hot water- at no additional energy cost.  With a Geothermal heating and cooling system, you can expect to receive approximately 60-80% of your hot water for free during summer.
  • A typical electric furnace will produce 1 watt of heating energy for every 1 watt of electricity put into the system.  On the other hand, if you put 1 watt of electricity into your Geothermal heat pump, your Geothermal system will pull an additional 3 watts of energy from the earth via your closed-loop system resulting in 4 watts of heating energy for every 1 watt of electricity consumed- that is 400% energy efficient!
  •  If you replace your standard heating and cooling system with a high efficiency Geothermal heat pump system, you stand to realize tremendous savings in your utility bills by reducing fossil fuel and electricity consumption. See more on energy savings here.
  • Tax credits!  If you choose to install a geothermal heating and cooling system in your home, you are eligible for a tax credit equal to 30% of the total installation cost.  So in addition to the monthly energy savings you will realize with your high efficiency Geothermal System, you will receive a 30% credit on the upfront installation costs of your home system.  Geothermal systems installed within commercial properties are eligible for a federal tax credit equal to 10% of the total installation cost.
