The term geothermal heating refers to any number of processes used by buildings around the world to both heat and cool an area throughout the year depending on the particular circumstances needed at the time through the use of the Earth’s natural temperature levels. This is done through any variation of methods both ancient and modern to regulate temperatures, utilizing both minor heat synchronization methods through piping systems and more extreme heat generated by regular volcanic activity.

One of the most common and well known methods of utilizing geothermal heating (as well as one of the most ancient) lies in the use of active volcanic spots found throughout the planet to heat water for personal usage and other temperature regulation purposes. These are common in areas where the Earth’s crust is particularly thin and in some cases an active volcano has already formed. Perhaps the most well known countries for traditionally utilizing water heated naturally by active volcanoes for both personal home heating and other everyday functions is Iceland, having even established a major tourist industry surrounding its natural hot springs supported by nearby volcanoes.

More common but less invasive methods of geothermal heating utilize what are known as “geothermal heat exchange” that help to regulate the temperature of many buildings in both summer and winter months by circulating air or liquid deep underground to naturally cool or heat it as necessary. Throughout the world roughly 50 feet beneath the surface the Earth maintains a constant temperature of approximately 45 degrees Fahrenheit in more northern latitudes to up to 75 degrees in southern areas, being deep enough to not be overly affected by surface temperatures while still maintaining some minor heating from the crust of the Earth itself.

Geothermal heat exchanges work to collect any radiating heat from the surface in summer months and cycle it beneath the surface for natural cooling, while in the winter time this is also a proven effective method for pre-heating many homes and saving large amounts of energy that would be lost otherwise through conventional heating methods. While currently these methods are most common in highly mountainous areas such as southern Oregon in the United States where many modern homes include them in their construction their effectiveness in helping any number of buildings large or small no matter their location in the world has caused their popularity to grow substantially in recent months and become incorporated into many modern day developments in countries across the Americas and Europe in particular.
