There are many advantages to using modern geothermal systems as an alternative to conventional HVAC. The geothermal systems of today are simple, highly effective and will last decades when designed, installed and maintained properly. Advances in design simulation and modeling software have made it possible to accurately “right – size” ground loop heat exchangers keeping initial capital costs minimized while optimizing building performance.
Geothermal heat pumps have an average 20 to 25 year life expectancy while the ground loop infrastructure will reliably perform for 50 to 100 years. The piping network, located in the ground, is constructed of robust high–density polyethylene (HDPE) or cross-linked PEXa material and is not exposed to the elements. Other system components are located inside the building, protected from adverse weather, and require minimal maintenance compared to conventional equipment. Ground loop systems are specifically configured to accommodate the space available, the building requirements and the local climate. Geothermal systems provide owners with extended equipment life cycles that drastically reduce replacement schedules and minimize operational costs. Proper design, periodic maintenance and continual monitoring ensure that the system continues to operate at peak efficiency and provide the performance expected by owners.
It is advantageous to have a system that can be relied on for decades that is environmentally friendly, economical and provides a comfortable building environment.
