Society has been more and more conscious about our environment. For example, when we use primitive technology to try to heat up our homes, the environment gets polluted. More and more, such systems are going the way of the dinosaur. Older systems are giving way to cleaner, more advanced, and more energy efficient systems. The goal is simple and clear - save more energy, and save the environment.



But saving the environment sounds like something meant for an idealist. Is it even practical to actively support such an idea? In the past, the answer would be no. However, today, technology has taken great leaps. And this has allowed us to provide practical solutions to the environmental issue. Take for example, the geothermal home heating system.

The geothermal home heating system cost several thousand dollars to install. While this sounds like a lot of money upfront, this is in fact a cost saving system for the homeowner. There is no burning, no pollution, and the entire system uses very little energy. How does it achieve that?

The geothermal heating system is not really new technology. It has been around since the Roman times. Romans use it to heat their villas and bathing water. So why is it that such a system hasn't been widely adopted for the modern society? It was only in recent times that more and more homeowners start to adopt this system again.

Perhaps as technology evolved, and other heating systems become readily available, it's easy to choose a more affordable heating system over the geothermal heating system. And this process will continue if alarm bells weren't sounded - other systems are hurting the environment and wasting valuable resources.

So we have to go back to the drawing board to rethink how we can continue to keep heating up homes without causing further harm to the environment. And the geothermal heating system has resurfaced as a viable solution.

The term geothermal is made up of two words actually - "geo" and "thermal". Geo refers to the earth, and thermal refers to the heat. You can probably guess where the system draws the heat from. That's right, the system draws heat from the earth. Or more specifically, it draws heat from the soil.

Water, refrigerants, or an anti-freeze solution is used by the geothermal heating system. The liquid runs through pipes that go underground, and draws heat from the soil. The heat energy is then transported via the pipes to the house. This happens when the weather is cold.

When the weather is hot (i.e. summer), the process is reversed. Refrigerants run underground to be cooled, and the cold refrigerants run through the house to cool the house down.

The greatest benefit of the geothermal heating system is great energy savings. It can save up to 70 percent on heating, and up to 50 percent on cooling. This means lower monthly utilities bills.
