Geothermal Myths That Need to Be Extinguished

Geothermal Myths That Need to Be ExtinguishedA lesser-known HVAC system option is geothermal heating and cooling system. Instead of transferring heat to and from the air outside your home like other HVAC systems do, geothermal systems actually exchange heat with the ground beneath your home. However, there are many geothermal myths that scare homeowners away from this option.

Geothermal Background

When you go just a few feet down below your home, the ground temperature stays relatively consistent throughout the year, usually ranging from 45 to 60 degrees. Compare this to the temperature of the outside air, which can range up to 100 on the hottest days. The bigger the difference in temperature between your ideal indoor temperature and the heat exchange source, the more difficult it is, and the more energy is required. This property helps geothermal systems achieve excellent heat transfer efficiency all year.

Common Myths

Here are some of the most important geothermal myths that need to be dispelled:

  • They use a lot of water: Geothermal systems actually use little to no water. Water is not consumed, it is used as part as the heat transfer agent along with antifreeze.

  • They are best for heating: These systems have the ability to absorb heat from the ground, but they can also deposit heat into the ground in order to cool your home.

  • Short life-span: There are two main parts of a geothermal system. A loop system is protected underground and conducts the heat transfer, and can last for over 50 years. The main indoor heat pump can be replaced separately every 20 to 25 years.

  • Take up space: You don’t need a huge yard for a geothermal system to be practical. Using a vertical loop system, you can often fit the entire system in just a few square feet.

  • They are noisy: Compared to most HVAC systems, a geothermal heating and cooling unit is whisper quiet.
