Geothermal HVAC systems are a smart choice for anyone looking to cool their home without wasting a lot of energy or damaging the environment. But while geothermal systems have their benefits, they also come with plenty of undeserved myths. Some of these myths can sound scary enough to put you off buying a geothermal HVAC system.
When it comes to your home's heating and cooling, getting the facts straight can make a tremendous difference. The following takes aim at a few common geothermal myths and dispels them using genuine facts and info.
1. Geothermal HVAC Systems Are Only Effective at Heating
If you're worried about how your geothermal HVAC system will work under the intense summer heat, then worry no further. Your geothermal HVAC system will cool your home just as effectively as any heat pump system.
In fact, the only difference between an ordinary heat pump and its geothermal counterpart is how it transfers latent heat. Instead of using traditional refrigerant, a geothermal heat pump relies on a solution of water and antifreeze or, in the case of open-loop geothermal systems, groundwater from a nearby source.
2. You'll Need Lots of Space for Your Geothermal Equipment
Not only have geothermal HVAC systems improved in overall efficiency, but they've also become more compact. Whereas an ordinary system would require your entire yard for installation decades ago, modern geothermal HVAC systems can be installed in a fraction of the space.
Instead of using traditional trenches, your geothermal installer can dig vertical boreholes to save yard space and minimize disruption to your existing landscaping. Making sure your home is properly sized for your heating and cooling needs can also help keep your geothermal HVAC system sizes reasonable.
3. Geothermal HVAC Systems Will Deplete Your Aquifer
If you've opted for an open-loop geothermal HVAC system, then you may be concerned about its effects on your water supply, especially if you use well water. Modern geothermal systems are designed to keep your groundwater supply in balance, ensuring that your water source doesn't suffer from depletion through long-term use.
Most geothermal HVAC systems deal with water depletion by depositing spent water into a return well, where it's eventually re-injected into the aquifer. Some HVAC units rely on an alternating two-well system that allows cool water deposited during the winter to be drawn out for cooling during the summer. This method can help increase the energy efficiency of your home's heating and cooling solution.
