Geothermal heat pumps have several advantages. Which geothermal system is right for a given installation, or even whether to use a geothermal system, depends on the circumstances of that particular installation.
Among the advantages are:
- In both commercial and residential installations, geothermal heat pump systems typically have lower maintenance costs than conventional systems as all equipment is installed inside the building or underground. This means that there is no outside equipment exposed to weather and vandalism. All refrigerant systems are sealed, similar to household refrigerators.
- Geothermal systems are very flexible. They can be easily and inexpensively subdivided or expanded to fit building remodeling or additions. They are particularly well-suited to “tenant finish” installations.
- In commercial installations, systems can save money by recovering excess heat from building interior zones and moving it to the perimeter of the building. They can also save money by allowing management to isolate and shut down unoccupied areas of the building.
- Refrigerant Loop geothermal systems have several advantages over other geothermal systems. They are potentially more efficient than water loop systems. They require fewer feet of buried piping than other geothermal systems, have no freeze problems, and better heat transfer.
