Heat pump or geothermal wells use the heat exchange properties of either groundwater or geologic material penetrated in the well to heat and cool residential homes and commercial buildings. 

Advances in technology are making it easier for consumers and businesses to better understand how they are using and saving energy. Geothermal energy is a renewable resource that is underutilized. Leveraging data and innovation are ways to promote a clean energy economy in America. The State Geothermal Data project, organized by the Association of American State Geologists with funding from the U.S. Department of Energy, is bringing data from all 50 states into the National Geothermal Data System (NGDS), in order to identify and characterize geothermal energy resources across the nation. 

How do Geothermal Heat Pump systems work? 

Note: Open-loop geothermal heat pump systems are not allowed to drain onto another property unless applicable permits are obtained through the department's Water Pollution Control Branch.
