Beneath the surface of the earths crust lies an energy source that is more than capable of providing us with heat and hot water. This energy source is known as thermal energy and can be harvested using specifically designed geothermal heating technology. This article will give you a better understanding of how thermal energy was created and how geothermal heating technology is able to harvest it.

But how does this energy under the earths surface occur? There are a number of reasons why the ground contains heat. Heat from the suns rays is absorbed for example. Also the earths core still continues to radiate out heat. Of course in some parts of the world thermal heat energy source is much stronger. No matter where in the world you are however, geothermal heating technology can quite effectively extract this hidden heat.

The concept of harnessing heat energy that is present beneath our feet is not new. In the Roman Empire water heated naturally underground by geothermal energy was put to use to keep their spas hot. Collecting naturally occurring heated water and transferring it to places to provide heat and hot water for personal use can really be thought of as a simple geothermal heating system. This harvesting of naturally occurring geothermally heated hot water is still used today in some parts of the world. Iceland, for example, makes full use of this naturally occurring energy source using geothermal power plants.

In todays world the Ground Source heat pump is fast becoming a popular geothermal heating system. As the name suggests the Ground Source heat pump harvests heat from beneath the earths surface and using a pumping method provides this heat wherever it is needed. Ground source heat pumps contain a loop of pipes that are sited beneath the ground. The loop of pipes contain a solution that is capable of absorbing any heat energy that exists in the ground. The solution is circulated through the pipe network and absorbs heat from the ground as it moves. The solution flows towards part of the system known as the heat exchanger. At this point the heat is extracted from the solution. This harvested heat is then used to directly warm living spaces and heat hot water tanks.

Geothermal heating systems are seeing an increase in popularity right across the globe. In general most people are becoming more environmentally aware and want to help lower their impact on the planet. Many people are also becoming fed up with having to pay rediculous prices for fossil fuels to heat their homes. That is why many people are switching over to geothermal heating systems such as Ground Source heat pumps to warm their homes and hot water.

Perhaps you would like to find out more about how geothermal heating systems such as the Ground Source heat pump work? It is a good idea to visit the websites of the specialist companies that focus on providing renewable heating and geothermal heating technology.
