Using ceiling fans during the winter
 
How many of you use your ceiling fan during the cooler months?

If you run your ceiling fan so it blows upwards you don't get a cool draft over you, but still mixes up the air in the room. With the fan on its lowest setting, you use very little energy and gain a few degrees in the room you are in.

Here is some testing that was done on builditsolar.com. As you can see, he has tons of heat just sitting up at the top of his room.

Thermal Stratification With High Ceilings -- A Test

i still haven't really tried using em much. but my ceilings are nowhere near that height...

hot air rises.
if your vents are in the ceiling (mine are) then you may want to run them on low.
I can tell the difference when the heat "kicks on" you feel the heat blowing around the room, that is until you acclimate to the temp change.

Not really, I haven't. I have LOW ceilings, rather than high. There's not much room for a fan without getting into the head-chopping region. With higher ceilings, I'd certainly give it a try.

That's really interesting, I'd never even thought of it. I'll have to give this tip to my mom, :)

If you check the bottom test (there are two) its for a room with a much lower ceiling. Once the fire place is lit up, there is a HUGE difference between 1' and 8'. As you can see, with radiant flooring the temperature is fairly uniform.

Our ceiling fans have been installed this summer, so it will be our first winter with ceiling fans. They can rotate in both directions so I note this idea and we may try it when we'll have to heat again.

Ofcourse I do; I use them whenever the A/C is running :-)

No Seriously I reverse them whenever it gets cold (<65F). (Still running A/C here)

I haven't before, but I can tell you that I will be getting the ladder up and switching the fan in my living room this afternoon. I'm going to give it a shot.

Thanks,
Cory

We don't even use the ceiling fan in our bedroom in the Summer.
