Geothermal HVAC System | Heating and Air Conditioning
Geothermal HVAC systems are earning a growing share of the HVAC market in the U.S. There are reasons why homeowner's owners select a geothermal system despite the initial higher cost. If you are considering installing the system, the following may assist you in determining if geothermal technology is the best fit for your home's heating and air conditioning.
How it Works
A geothermal system uses the energy of the Earth's underground temperature to heat or cool your home. Underground, approximately 4-6 feet or deeper, the ground maintains a constant temperature throughout the year, typically between 45F and 65F. During the winter the underground temperature is warmer than the surface and in the summer it's significantly cooler.
Pipes are buried at a determined specific depth and filled with water, antifreeze or other liquid medium used as a preconditioned refrigerant that is either heated up or cooled down in the heat pump, depending on the time of the year. By using a refrigerant with a preconditioned temperature you can experience greater energy efficiency in any weather.
Clean, Green and Safe
Unlike gas heating, the geothermal heat pump operates cleanly using electricity. More than 1 million residential geothermal heat pumps are currently installed in the U.S., with more than 60,000 units installed in the U.S. each year.
Geothermal heat pumps currently in use offer positive influences on the environment:
- 40 trillion BTUs of fossil fuels saved each year and growing as more are installed
- 1.6 million metric tons of carbon are eliminated each year and counting
- 8 million kWh of power are saved each year
- More than 5.8 million metric tons of CO2 are eliminated each year
- Reduces the need for electrical generation by 2.6 million kW each year and growing
Great Choices Affect Us All
To place these statistics in a different perspective, the current number of geothermal heat pumps in service today is the equivalent of:
- Planting more than 385 million trees, and adding almost 240,000 trees each year
- Reduced consumption of foreign fuels by 21.5 million barrels of crude oil annually
- Removing 1,295,000 automobiles from the road to date, with the number growing by 77,700 each year
Superior Life Span
With proper maintenance, a geothermal heat pump will on average last for 25 years, while the underground components have an expected lifespan of 50 years under normal conditions. This is more than double any other heating and air conditioning system.
An Investment That Continues to Give
A geothermal heat pump is an investment with energy savings that begin immediately and continue to give for the long lifespan of the system. While the initial investment is higher than conventional air sourced heat pumps, the energy savings can offset the costs of the installation over a reasonable period of time. Furthermore, with tax credits and rebates, the return on your investment can potentially be in as little as 3-5 years.
Geothermal systems save up to 70% on the heating bills and 40% on air conditioning costs when compared to even the most energy efficient conventional heating and air conditioning systems.
The geothermal heat pump system installation is higher than air source heat pumps due to the need to install a ground heat exchanger. However, it is this connection beneath the earth that enables the system to yield up to 4 kilowatts of heat for every 1 kilowatt of electricity consumed.
It is essential to ensure the installer is an HVAC technician with ample experience, and proficiency in geothermal installation. Experience and knowledge of the technology is a primary factor in ensuring your satisfaction and the performance of the geothermal heating and air conditioning system.
As with any heating and air conditioning system, the geothermal system size must match the home's requirements to prevent short cycling and premature wear on components. A geothermal system is only as good as the skills, experience and knowledge of the installer.
While the required maintenance of geothermal heat pumps is minimal in comparison to other heating and air conditioning systems, some maintenance is necessary to ensure that the system provides the energy efficiency and comfort it is popular for.
