Anyone seen this article "Heat Pump, Schmeat Pump" in finehomebuilding.com's latest newsletter? Apparently, it's in the magazine as well. Heat Pump, Schmeat Pump - Fine Homebuilding Article Seems they need to get out of their cubicles and talk to more people in the field - installers and homeowners alike. From my experience, I've saved a bundle, over $4000, on my heating costs this past winter since my geothermal system was installed. That money translates into a whole lot of oil, not used. Plus, my house has been warmer than either an oil or a gas system ever made it. My six ton system cost $50,000, less $1000 rebate from my local electric company, so $49,000, then factor in the 30% Federal tax credit of $14,700, which brings it down to $34,300. I can tell you that I got a number of proposals for new fossil fuel systems for that price to heat and air condition my old house. Now subtract my first winter's savings on fuel (January - April $4000 +) and apply that to the cost and my out of pocket cost is down to $30,000. Going by what my cost has been so far, it looks like I will have a ROI of seven and a half years at today's oil prices. However, it will end up being much less since next year will be my first entire heating season using geothermal, as I didn't have it in October, November or December. If oil prices go up, my ROI will be far shorter. That doesn't include any savings on heating our water either, because I left my oil water heater running to use up the rest of the oil in our tank. It just ran out three weeks ago and I switched over to our new electric buffer tank. Interestingly, while the buffer gave us plenty of hot water just on its element alone, because the weather was so warm, the geo system didn't kick on. However, suddenly the temperature dropped and with the system going again, our hot water has noticably jumped up in temperature now that the desuperheater is finally turned on and contributing heat. The oil water heater is going to be replaced with a Marathon DHW heater shortly, and the buffer will be returned to its proper job of just sitting there, buffering for the new water heater. As a homeowner, am I delighted I decided to choose a geothermal system over an oil or gas one? Fine homebuilding, are you listening? YEAH!!!!!!!!!!!!!!!!!!
