Geothermal Heat Pumps
Geothermal heat pumps take advantage of the relatively stable ground or water temperatures near the earth’s surface (roughly 50 to 55 degrees F year-round) to heat or cool buildings above-ground. Instead of creating heat, geothermal pumps “move” heat in the desired direction. In the winter, geothermal pumps capture the latent heat stored in the ground and use a compressor to “bump up” the temperature in your home to the desired level (e.g. 71 degrees). In the summer, the system captures the heat in your home and moves it back to the ground.
Geothermal Advantages
- According to the U.S. Environmental Protection Agency, geothermal heat pumps are the most energy-efficient, environmentally clean, and cost-effective systems for temperature control
- Stable and reliable
- Offsets the use of fossil fuels
Geothermal Limitations
- More expensive to install in existing homes (vs. new homes under construction). Additional expenses may apply to ensure proper weatherization and ventilation in an existing home
- Must be installed by an experienced professional
