People hesitate to use geothermal installations at their house due to some common misconceptions. While the geothermal system is good for heating and cooling your home, there are a few myths that may be bothering your decision. We have listed the most common myths about geothermal systems to help you ease your decisions.
Geothermal systems use energy
Many believe that geothermal systems do not use renewable technology as they consume electricity. The geothermal systems use only one unit of electricity to initiate five units of heating or cooling from the earth to a building.
Geothermal alternatives are better
People feel that photovoltaic power and wind energy are better renewable technologies over geothermal systems, but the geothermal systems save more energy compared to other installations. While their other technologies are equally effective, they consume four times more kilowatt-hours of energy then geothermal systems.
Geothermal HVAC needs a lot of space
The earth loop for a geothermal system can be installed vertically, which only requires a little space above ground. If there is an aquifer that can be tapped, the unit will require only a few square feet of space in your backyard.
Geothermal heat pumps are noisy
The advanced geothermal systems are very quiet, and no equipment makes enough sound to bother your children or your neighbours. The heat pumps may have a few vibrations, but that does not make them noisy at all unless you have hanged keys on them.
Geothermal systems wear out
People feel that geothermal systems can wear out with time, but the earth loops can actually last for generations. The heat-exchange equipment can last for at least a decade if it is installed indoors. Different parts of the geothermal system can be replaced individually, so you do not have to spend money on a new system.
Geothermal systems only work in heating mode
Geothermal systems are as effective in cooling the indoors as they can warm it up. They can be engineered to require no added backup heat source if desired. Some people also prefer to have a small backup system for winters.
Geothermal systems cannot heat water
People think that the purpose of a geothermal system is limited, and it cannot help heating a swimming pool and home at the same time. The advanced systems can be designed to do both tasks simultaneously.
Geothermal systems use refrigerants
People worry that the geothermal systems can put refrigerant lines into the ground that can affect the foundation. In reality, most of the systems available today use only water in the loops or lines so that the topography of the area does not get affected.
Geothermal systems consume a lot of water
The geothermal systems consume no water. The aquifer used to exchange heat with the earth recycles the water again and again. The old pump and dump systems do not exist today, which can save millions of gallons of water for a lifetime.
