Geothermal’s Top 10 Takeaways


If you know nothing else about geothermal heating and cooling, know this – especially if you’re thinking of retrofitting your present Wilmington home’s HVAC system or at a loss for what to install in the new home you’re building:
  1. Geothermal HVAC systems are widely considered the most environmentally friendly available. Their relatively simple technology harnesses subterranean temperatures to furnish your Wilmington home with winter heat and summer cooling. Thus, your home and the earth are always in sync, joined together in a distinctive – and distinctively harmonious – home-earth symbiosis. Sound a trifle too pompous? All it means is that, with geothermal heating and cooling, your home isn’t upsetting the natural order of things. Instead, it’s becoming a “nicer” part of the environment.
  2. Geothermal HVAC systems pass muster as “renewable energy technology.” Certainly, they run off of electricity. But they don’t use much of it for all the reward you get. Just one unit of electricity can convey up to five units of natural heating or cooling from the earth to your home.
  3. Geothermal HVAC systems are far more efficient than solar (photovoltaic) or wind power technologies. Generally speaking, solar and wind technologies, whatever the pull of their “renewability,” eat four times more kilowatt-hours of electricity per dollar spent than geothermal systems.
  4. Geothermal HVAC systems won’t dominate your yard. Don’t have much yard space in the first place? No bombshell there: most home lots in Wilmington and elsewhere anymore occupy a fairly small the polyethylene piping needed for the geothermal earth loops doesn’t have to be buried horizontally. It can be dug in vertically and run as deep as 100 to 400 feet. Very little above-ground surface is necessary in any event, whether vertical, horizontal, open (well water), or pond loops are installed. Result? You can keep your little patch of paradise a whole lot greener.
  5. Geothermal HVAC systems are remarkably quiet. Every aspect of a geothermal system is designed and engineered to operate significantly quieter than traditional gas furnaces, heat pumps, or air conditioners. More comforting still, there’s no outside unit, so you and your neighbors areen’t subjected to the irritation of fans, belts, and compressors whirring, whining, and rattling away at all hours!
  6. Geothermal HVAC systems are long-term heating and cooling solutions, designed, engineered, and built to last for generations. Present-day geothermal technology, manufacturing guidelines, and installation procedures assure ground loops of uncommon longevity and heat-exchange equipment that will continue working impeccably for decades. It helps, naturally, that the heat-exchange equipment is protected indoors. At least, when it does in due course have to be repaired or replaced, you won’t likely be redoing the ground, well, or pond loops along with it. So replacement costs can be kept down.
  7. Geothermal HVAC systems don’t need much maintenance at all. The earth loops, as mentioned, are designed to last for generations, and when correctly buried, will do so without any need for intervention. Fans, compressors, and pumps, kept safe indoors from weather extremes, need only sporadic scrutiny as well as periodic filter changes and a yearly coil cleaning.
  8. Geothermal HVAC systems are as adept at cooling as they are at heating. The old notion that geothermal HVAC systems don’t cool as well as they heat has been substantially buried by steady improvements in the manufacture of geothermal technology.
  9. Geothermal HVAC systems can be modified to multitask. Okay, so you’ve determined you want to heat your home’s water geothermally. But can a geothermal system provide ambient heat for your home as well? And what if you have a swimming pool? Rest easy. Today’s systems can handle it all and handle it at the same time, with no favoring of one task over another.
  10. Geothermal HVAC systems are becoming more and more affordable – even when not subsidized by federal and local tax incentives. Congress has yet to restore federal tax credits for geothermal heating and cooling that ended December 31, 2016. Nevertheless, a number of factors – material and technological advances, new installation practices, and greater competition in the marketplace, primarily – are helping to better align geothermal solutions with the cost of more run-of-the-mill heating and cooling methods.
