I was up one night checking out an issue with my furnace. And I turned on the attic fan to ventilate the attic for comfort and safety. It is a huge fan and, for me, a power hog. Hard to pin down the exact figure, but it uses something in the realm of 230 watt/hours give or take. I finished up my work and forgot to turn it off. About 3 days later, while looking at the always on numbers, I noticed that the amount of power I was using was about 200W more than the average I had been using, and I had no way to account for it. Since my Always On usually only adds up to about 50W, 250W is a pretty substantial. I started going around the house looking for things that I might have left plugged in and on. then I thought about the attic and considered the possibility that I might have left the attic lights on. And then it hit me. THE FAN!!! And as I said in my post, I don’t feel…
