Wind Turbine Generators

Beneath the surface of the earths crust lies an energy source that is just waiting to be tapped into in order to provide us with heat and hot water for our homes. This energy source is known as thermal energy and can be harvested using specifically designed geothermal heating technology.  This article will provide you with quick and simple overview of how thermal energy has come into being and how modern geothermal heating systems tap into this energy supply.

But how exactly has thermal energy come into existance? Heat naturally occurs underground because of several energy sources. For example, sun light, the earths core, and other radioactive materials that exist in the ground all generate heat. The strength of this heat energy trapped beneath the surface of the ground  will of course depend where you are in the world. It does not really matter where you are in the world though as geothermal heating technologies are able to extract heat from the ground however weak that heat is.

The concept of harnessing heat energy that naturally occurs under ground is not new. Thousands of years ago the Romans grasped the idea that naturally occurring hot water heated by geothermal energy could be used to heat their spas and some of their buildings.  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. Similarly today, countries like Iceland that are lucky to have a bountiful supply of geothermally heated hot water put this to use to help provide electricity and heat energy 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 use a series of pipes that are laid underneath the surface of the ground. The loop of pipes are filled with a soltuion has properties to absorb geothermal heat energy directly from 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 very aware that they need to change the way they do things in order to become more environmentally friendly. Most people are also becoming increasingly frustrated at the incredibly high prices they are paying for fossil fuels such as gas and coal. Geothermal heating systems such as Ground Source heat pumps provide just the answer many people are looking for.
