Among the many types of HVAC systems available, geothermal heat pumps stand out distinctly. All heat pumps are exceptionally efficient and excellent for the environment, however, thanks to their unique technology, geothermal heat pumps are considered the most eco-friendly HVAC system on the market. Unlike most heat pumps that rely on air to heat and cool, geothermal heat pumps harness the constant temperature of the Earth’s crust. By tapping into the Earth’s heat, these systems efficiently warm buildings before returning the excess heat back to nature during its cooling cycles.
Geothermal heat pumps operate through two primary processes of heat exchange. The closed-loop system continuously circulates a mixture of water and non-toxic antifreeze through a series of pipes buried in the ground to transfer heat. The different types of closed loop geothermal systems are based on the way the pipes are laid out and include: horizontal, slinky or vertical. The second type of system is an open-loop system. In this setup, groundwater is used for the heat exchange process and then discharged back into the ground or nearby water source.
Regardless of whether the system is open or closed loop, the indoor circulation system remains consistent in delivering temperature-controlled air throughout the building. Despite a more complex installation process, geothermal heat pumps offer comparable, if not superior, comfort levels when installed by trained and licensed HVAC professionals. These systems are more complex and, therefore, must be carefully planned and sized for the building. However, when implemented well, they’re an excellent option for buildings of all sizes. Geothermal heat pumps are best suited for new home constructions. We are happy to work with your general contractor to design and develop a system for you.
Beyond their efficiency and eco-friendliness, here are a few more stand-out benefits of geothermal heat pumps:
- They offer consistent and reliable temperatures throughout every season.
- They tend to be low maintenance and long-lasting.
- The bulk of the equipment is located outdoors, so they can be ideal if you’re looking to save space.
