From the current issue of Home Power magazine:

"Making the Most of Your Ceiling Fan"

http://www.homepower.com/articles/home-efficiency/electricity/making-most-your-ceiling-fan

The temperature of the motor was far higher than anything

else in the room, including windows exposed to direct sunlight.

Not only was the fan not cooling the people who weren�t in

the room, but it was also working as a little space heater.



Is this a joke article? He lists some useful info and then draws faulty

conclusions. I think the lead in line is a perfect example...



A ceiling fan can heat up to about 100�F when running



Wow! 100�F!!! That is pretty much nothing. The incandescent light

bulb in the same fixture is thousands of degrees and likely puts off

more heat. I think the case for the fan heating the room is a bit

overstated. More useful would have been a simple statement of the

wattage of the fan.

Or better yet, actually measure it using a Kill-A-Watt or
similar. I agree, I don't believe a small motor like that is going
to generate much heat. From what I see, typical is 50 to 75W or
so. I just felt the motor on mine, running on medium speed,
and it doesn't feel warm at all.



The comparison to the windows is totally absurd.

They let in direct radiant heat from the outside. I can assure you than

nearly any window in your house lets in more heat in the summer than the

fan puts off. The temperature of the glass has no bearing on the heat

coming in through the window.

The advice that the fan only helps if you're there to benefit from
the breeze I agree with.
