As I mentioned in my last post we’re converting our house from a traditional fuel oil furnace to a sustainable geothermal ground source heat pump. But instead of just telling you about our system I want to go into depth and do a series of posts about everything you need to know as a home owner if you’re considering going geothermal. When I was researching residential geothermal systems I was disappointed in the quality of info out there about geothermal systems. Yes, there is lots of info about geothermal systems but almost all of it is describing how ground loops work. Go ahead and Google “geothermal systems” you’ll find pretty graphics of cold water/refrigerant mixtures going into the ground and hot water/refrigerant coming out. Once you wrap your head around the concept of getting heating and cooling from the Earth is that all you need to know as a home owner? The answer is NO.
In an effort to help inform others I’m going to write an 8 part mini-series from my point of view as a homeowner and HVAC engineer. I’ll give you every question you need to ask your contractor and calculations you can do to determine the true cost of going geothermal. If you’ve ever considered installing a geothermal system you’ll want to read this!
