A geothermal heat pump moves heat to or from the ground or a nearby body of water. Conventional heat pumps interact with the outside air instead. Since temperatures underground and underwater are almost constant, geothermal HVAC systems are more efficient for your Sea Island, Georgia, home. During the winter, the ground is warmer than the air, so transferring heat to your home uses less energy.
In summer, a geothermal HVAC system cools your house by directing excess heat to the cool ground or water rather than the hot outdoor air. Learning exactly how a geothermal HVAC system works will help you decide whether it’s the right choice for you and your family.
The Parts of a Geothermal Heat Pump
Like conventional heat pumps, geothermal units use indoor air handlers. Instead of an above-ground compressor, a series of pipes or loops transport water or refrigerant, transferring heat to or from the water or ground. Most pipes used in geothermal systems are polypropylene, a durable type of plastic. They can last for over half a century, or you can choose even stronger copper pipes.
Most geothermal heat pumps use horizontal pipes. If there’s not enough room in your yard or you don’t want to harm your landscaping, you should have vertical pipes installed instead. Instead of trenches, they’re placed in holes that are hundreds of feet deep but only a few inches wide. If you have a well, pond, or lake nearby, you can reduce your installation costs and avoid digging completely by choosing an underwater system.
Many geothermal systems can provide hot water, so you won’t need a separate water heater. You can easily add a radiant heating system that moves warm water underneath your floors. It gets rid of cold floors in winter and increases the value of your home.
