Energy efficiency is a growing concern for anyone who cares about the future of the Earth. Geothermal heating is one of the oldest methods of energy retention, and it’s increasingly becoming popular with today’s homeowners. Many people who want to learn how to increase the efficiency in their home, without increasing their carbon footprint want to know what geothermal heating is.

Geothermal heating systems utilize what’s called ground loops, otherwise known as Earth coils. These are heating pipes that are utilized to pull heat from under the Earth’s crust and deliver heat to your home. Because you are reducing your dependency on energy and fossil fuels, this renewable energy source is gaining traction in eco-conscious homes around the world. The pipes are installed underground and using the relative temperature of the earth’s heat your energy costs can be reduced between 40-60%.

The energy that’s tapped during the geothermal process is the heat that’s retained under the Earth’s crust. The energy that’s presentsince the original formation of the planet, this energy is renewed by the decay of minerals and solar energy absorbed by the crust of Earth. Geothermal heat spots are centered at certain locations around the world, where volcanic activity occurs. In these specific regions, the groundwater and earth rise in temperature during specific periods. This heat is transferred around the Earth, and the rating for this heat dispersal is known as the Mean Annual Air Temperature.

This is one of the most renewable and efficient forms of energy because the Earth retains heat from the sun naturally. Up to 50% of the sun’s energy is absorbed during the day, which gives geothermal energy an advantage over traditional renewable energy types. Environmentally friendly as well as cost efficient, there are a lot of reasons why geothermal heating could be the future of renewable energy.

Increased geothermal heat can be found typically up to 6 meters underground, and can be extracted with a heat pump. The right geothermal system can improve your home’s heating index and overall energy efficiency, and can pay for itself in a relatively short amount of time. Being able to harvest the heat from the tectonic plates of the Earth’s crust is what powers this unique style of renewable energy. If you are interested in investing in your home and learning how geothermal heating can benefit you, read on to see the top facts behind geothermal energy.

Geothermal Energy Facts

1. Geothermal HVAC systems and heating can be a superior renewable energy solution compared to solar power and wind power. Compared to photovoltaic and wind power based renewable energy sources, geothermal systems are up to four times more efficient. This makes geothermal systems the far more superior and cost effective means to renewable energy.

2. Geothermal HVAC systems require very little real estate and can fit into the smallest of spaces. Capable of being installed in a small footprint helps, as the polyethylene piping earth loops are installed into the Earth. Depending on your install location, these pipes may be able to be installed vertically which means the footprint is very small. Because your geothermal system is a closed loop system, and the heated water is returned to your internal tank, it’s not being consumed or used.

3. Geothermal systems are quiet and can last for generations Remarkably quiet operation and self-contained piping mean that your geothermal heating system is extremely durable. Despite many common misconceptions, these pumps are not overly noisy and do not disturb your neighbors. Further, the nature of the polyethylene piping in your geothermal system will more than likely outlast your home. Because of the long lasting nature of a geothermal HVAC system, it’s a smart investment for your home or property

4. Geothermal HVAC systems utilize water and no refrigerants. Many people think that geothermal HVAC requires the use of refrigerants or harsh chemicals to be stored in the ground. In fact, most systems use just water, and when combined with the right aquifer tank and sump setup, it’s a completely contained system that doesn’t waste or consume more water over the life of the geothermal system.

5. Federal and state tax incentives can make Geothermal HVAC technology affordable Depending on where you live there are several government tax incentives that can help you deal with the initial cost of installation. Most of these incentives work as tax credits and can provide you with a good way to manage the installation costs. Because most traditional HVAC systems do not require digging into the ground, they can range between $2,000-$3,000 dollars per ton of heating capacity. Geothermal systems cost between $5,000 and $8,000 per ton of heating capacity. So if you are considering this solution make sure to take advantage of the tax breaks. The installation process of these geothermal systems is improving every day, and the materials used are getting cheaper and stronger. This shouldn’t stop you from using the incentives put in place by the government, and improving your home with tax dollars.

6. Geothermal HVAC Systems can cool and heat as well as traditional systems Contrary to popular belief, geothermal HVAC systems can cool as well as they can heat, if not better. Because they can be engineered and assembled to require no additional backup heat sources, you can use your geothermal system to provide a comprehensive solution for your home or property. Because your geothermal heating system is sealed, you aren’t wasting any energy and making total use of the thermal energy stored in the Earth. This kind of efficiency is unheard of in a traditional HVAC system, and it’s the leading reason people are turning to geothermal energy as the next renewable source of power.

7. Geothermal HVAC units are a comprehensive heating and cooling system Properly designed geothermal systems can take on multiple loads at the same time. The heat that’s absorbed through the geothermal piping gives you the best chance to decrease your energy bill. Circulating water through the pipes in the Earth’s crust allows you to extract the natural heat and distribute it as you deem. Looking for a turnkey solution to geothermal solutions?
