Lets take a look at why Geothermal systems are mostly regarded as the most environmentally friendly heating systems for both the natural and indoor environment.
Less Fossil Fuel Use
By transferring renewable thermal energy to and from the ground at high efficiency, geothermal systems reduce the need to extract, transport, and burn fossil fuels. The heat pumps do require a degree of electricity but this is much less than traditional heating and cooling systems. This translates into a direct reduction in the emission of pollutants and greenhouse gasses such as carbon dioxide (CO2), sulfur dioxide (SO2), and nitrous oxides (N02).
A Cleaner Indoor Environment
Geothermal systems are not only beneficial for the natural environment, they are also one of the best choices for the indoor environments we live and work in. With no fossil fuels being burnt, geothermal systems have none of the risks associated with carbon monoxide and open flames.
No Chemicals and Sterilization
Geothermal systems also eliminate the need for chemicals and sterilization agents used to prevent algae and bacterial growth in cooling towers, which can taint air drawn through building ventilation ducts. Geothermal systems provide excellent indoor air quality. They are suitable for heating and cooling medical/surgical, research, and industrial facilities requiring sterile conditions.
