Geothermal’s Top 10 Takeaways


If you don’t know anything else about geothermal heating and cooling, know this – especially if you’re considering redoing your current Alaska home’s HVAC system or still undecided about what to install in the new home you’re building:
  1. Geothermal HVAC systems are among the most environmentally friendly you can buy. Their simple technology channels subterranean temperatures to provide your Alaska home with winter heat and summer cooling. Thus, your home and the earth are always in sync, fused together in a unique – and uniquely sympathetic – home-earth symbiosis. Sound a little too grandiose? All it means is that, with geothermal heating and cooling, your home isn’t “messing” with the natural order of things. Instead, it’s becoming a “nicer” part of the environment.
  2. Geothermal HVAC systems meet the definition of “renewable energy technology.” Sure, they run off of electricity. But they don’t need much of it for all the benefit you get. Just one unit of electricity can transfer up to five units of natural heating or cooling from the earth to your home.
  3. Geothermal HVAC systems are much more efficient than solar (photovoltaic) or wind power systems. 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 anyway? No revelation there: most home lots in Alaska and elsewhere anymore occupy a comparatively You’ll be relieved to know, however, that the polyethylene piping used for the geothermal earth loops doesn’t have to be buried horizontally. It can be dug in vertically and run to a depth of anywhere from 100 to 400 feet. Almost no above-ground surface is called for at any rate, 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 element of a geothermal system is designed and engineered to run significantly quieter than ordinary gas furnaces, heat pumps, or air conditioners. More impressive still, there’s no outside unit, so you and your neighbors areen’t subjected to the annoyance of fans, belts, and compressors whirring, whining, and clattering away at all hours!
  6. Geothermal HVAC systems are long-term heating and cooling solutions, designed to last for generations. Present-day geothermal technology, manufacturing guidelines, and installation procedures ensure ground loops of extraordinary 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 ultimately need repairing or replacing, you won’t likely be redoing the ground, well, or pond loops along with it. So replacement costs can be relatively insubstantial.
  7. Geothermal HVAC systems don’t require much maintenance at all. The earth loops, as mentioned, are designed to last for generations, and when appropriately buried, will do so without any need for intervention. Fans, compressors, and pumps, kept safe indoors from weather extremes, require only a sporadic examination as well as periodic filter changes and a coil cleaning once a year.
  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 essentially laid to rested by ongoing improvements in the manufacture of geothermal technology.
  9. Geothermal HVAC systems can be customized to multitask. Okay, so you’ve chosen to heat your home’s water geothermally. But can a geothermal system provide ambient heat for your home also? And what if you have a swimming pool? Relax. Today’s systems can do it all and do it all at once, with no favoring of one task over another.
  10. Geothermal HVAC systems are becoming a lot more affordable – even when not subsidized by federal and local tax incentives. Congress has yet to reinstitute federal tax credits for geothermal heating and cooling that ended December 31, 2016. That said, a number of factors – material and technological advances, new installation practices, and increased competition in the marketplace, predominantly – are helping to better align geothermal solutions with the cost of traditional heating and cooling methods.
