People are on the search for new power sources because fossil fuels are increasing in cost as each day passes. What homes need might just be geothermal heating.
Geothermal heating is a fairly old concept that has gained a new life through advances in modern technology and materials. The concept can be explained using a simple example.
In many parts of the world, homes come with basements. If you've lived in such a home, you've probably failed to notice an interesting fact. Everyone knows that a basement will remain relatively cool during a summer, no matter how hot it gets outside. But not many are aware that a basement is quite warm during the winter. This happening is related to how Mother Earth regulates herself.
It seems that geothermal power will take advantage of the stable temperature of the soil. Regardless of temperature fluctuations on the surface of the ground, soil below five feet remains at a fairly constant temperature range of 50 to 55 degrees. During the cold season, this can be used to create geothermal heating for a structure.
The mechanics involved are quite simple. First, plastic piping loops are dug into the ground so there is a circuit for heat transfer. Depending on the season, liquid is run through the system to exchange heat or cold with the ground and suck up the opposite. The altered liquid is run through a refrigerant process to get cold air, which will be circulated in the building or home during hot weather. In winter, the process runs backwards and the cold air in the home is forced into the ground where it circulates and is subsequently compressed. The compression process will heat the fluids to over a hundred degrees, producing hot air.
An easier way to think of the above concept is to consider the season. In the winter, the system will transfer cold air to the ground in exchange for warm air used in your home. This is contrary for the hot season. A geothermal pump can help you save more than half of your energy costs.
