By taking advantage of the relatively constant underground temperature, geothermal systems use up to 50% less energy than conventional heating and cooling systems.
One recreation center was able to get rid of the cooling towers used for its chiller and condenser loop and replace it with a geothermal system that's much more efficient. In addition to energy savings, other benefits include lower noise level, less maintenance and more design flexibility.
Geothermal systems typically cost more to install than conventional heating and cooling systems. However, their lower maintenance and operational costs, as well as system durability, can provide you with a reasonable return on your investment.
