One of the most interesting types of HVAC systems are geothermal systems. A geothermal heating and cooling system is a type of heat pump that exchanges heat from your home with the earth beneath your feet. It has an excellent efficiency and effectiveness, but there are many geothermal myths that steer homeowners in the direction of more popular systems.
How Geothermal Systems Work
When you heat your home in the winter, you have to extract heat from cold air outside, which is difficult. The ground a few feet down, however, is much warmer and easier to get heat from. In fact, that ground barely changes temperature throughout the entire year, ranging from 45 to 60 degrees. Since it’s much easier to extract the heat from the ground, you can achieve excellent efficiencies.
Geothermal Myths Busted
These are the most common geothermal myths that homeowners often believe:
- MYTH: These systems are noisy. There are two main parts of a geothermal system: an indoor heat pump which makes a small amount of noise, and an underground loop system, which makes virtually no sound at all.
- MYTH: Geothermal systems can’t cool. Geothermal systems are designed to be fully functional for both heating and cooling your home.
- MYTH: These systems don’t last. The longest-lasting HVAC systems are geothermal systems. The loop system can last for over 50 years, while the indoor heat pump only has to be replaced every 20 to 25 years.
- MYTH: Geothermal requires too much space. While some geothermal systems use a lot of space under a yard, there are vertical loop system configurations that only require a small area of land.
- MYTH: These systems consume too much water. The loop system has a water mixture that runs through it to act as a heat transfer agent to exchange heat with the ground. No water is actually consumed.
