Few HVAC systems can beat the efficiency and eco-friendliness that a geothermal-based heating and cooling solution offers. Geothermal systems take advantage of the natural heat energy stored in deep within the ground, providing your home with eco-friendly comfort year-round.
Most geothermal HVAC systems rely on ground loops to transfer heat energy to and from your home. If you plan on replacing your current HVAC system with a geothermal unit, you'll need to choose between an open-loop or a closed-loop system. The following offers an in-depth explanation of both types, along with their unique pros and cons.
Pros and Cons of Closed-Loop Systems
Just as the name suggests, closed-loop geothermal HVAC systems feature a completely self-contained loop of flexible underground piping that circulates coolant between the heat pump unit and the ground. Unlike ordinary heat pumps that use R-410a refrigerant as a heat exchange medium, closed-loop geothermal heat pumps capture and transfer heat using fluids that are similar in composition to anti-freeze.
Closed-loop geothermal HVAC systems have a few unique strengths when compared to their open-loop counterparts:
However, there are a few negatives to consider when choosing closed-loop systems:
Pros and Cons of Open-Loop Systems
Open-loop geothermal HVAC systems use groundwater in place of the antifreeze-like fluids used by their closed-loop counterparts. True to its name, an open-loop geothermal HVAC system features a loop with inlets and outlets for collecting and discharging groundwater. Open-loop systems pull water from wells, ponds, and other nearby water sources. After circulating through the geothermal equipment, the water is discharged into a separate well or directly back into the lake.
Like closed-loop geothermal HVAC systems, open-loop systems have plenty of strengths that make them appealing over their aforementioned counterparts:
Open-loop geothermal HVAC systems also have their share of caveats to consider, as well:
Important Factors to Consider
Before diving headfirst into the world of geothermal HVAC systems, you'll want to consider the following factors that could influence the type of geothermal equipment you end up with. These factors can also have a tremendous impact on your home's overall comfort:

Your outdoor heat pump unit needs to be protected from the elements. You should have it somewhat covered to keep snow and ice from settling on it and prevent tree limbs from crashing down on it. My blog will show you some creative ways to protect your heat pump unit outside of your home. The protective unit doesn't need to be unsightly by any means. You can come up with several unique ways to disguise and protect the heat pump unit that you will like and will do the job it needs to do for many years into the future.
