Two days ago I talked to a friend that had moved back to northern Michigan. He had bought a EdenPure a few years ago and had problems so sent it back. Supposedly they have improved them, so he bought another one. So far after a month, he loves it. He said that plus his fireplace [with the heat blower] it keeps the house at 68-71 degrees all day long, and the only time his furnace comes on is at night.
I was thinking of buying one, but now after hearing the downside here, I don't know. I do wish I hadn't sold the oil space heater I had when I moved to Florida from Michigan. It warmed the entire basement, eliminating the cold coming up into the house. Since now living in Alabama, we do get cold winters here.
