Does anyone have any real world experience using these fans? I am wanting to purchase one instead of using the current Ecofan which I am using now. I have used the Ecofan for three years, but now it does not run as fast as it used to. I have read where the Ecofan slows down and can be ruined if your stove temps get too high and now I believe it. I have an Avalon Olympic free stander which sometimes gets up to 650 to 700 degrees. I am thinking the Heatwave can take the higher temps at least that is what the adds say. Is the Heatwave as quiet as the Ecofan?
