    To accompany my install from last spring I put ceiling fans in my tall ceilings (9' I believe). Just to make sure I have this right, for winter to help with the heating of the house, my fans should be on the lowest setting and moving opposite to summer time cooling (i.e. drawing air rather than pushing down). Is this right? How much difference
    have people seen?

    They most all have a little black slide switch built in from the factory. Have you never installed a fan?

    Most ceiling fans are designed to be reversed. Sometimes they can be wired to a wall mounted fan switch that allows one to reverse them. The fanciest units have a wireless remote control. But almost all have a side slider switch that allows reversing the fan.

    It all has to do with the layout of your house and the room the stove is in. Normally the draw up and slow is the one most use but again , every house is different. I have been in a few homes that downward force is best. I run mine on draw and slow when the stove is just doing its thing and the outside temp is 10° and higher , under 10° i kick the speed up to medium.

    I like my fans on Forward (pushing down)
    The reason Im a lazy ass and when Im done with my 13 hours day dealing with stoves I go home and flop my ass on the Sofa. and watch what I have recorded on the DISH.

    If I have the fan on Reverse (pulling up) then I can feel the COLD air from the floor pulling accross my lazzy ass lieing down.
    But with Forward the HOT air from the ceiling it will push down hot air on me and the cold air will go up the wall.

    Just my Comfort.

    There are two ways to look at this since hot air rises the fan pulling down will push the hot air down the other way of looking at it the fan will act as a mixer of air and create even heat rotating at any direction pick you poison

    Either way. As long as air is moving you are geting the benefits of having the fan on.

    95% of the time..........If just room air mixing ......... down. If you are trying to heat all or most of the house i would say up.

    Human skin will sense the air movement and feel cooled. By reversing the flow the air in the center of the room is drawn upwards and out towards the outer walls where is decends to be recirculated again. This is a much more comfortable way to run the fan in winter. Low speed is best.

    Of course, if the room is at 90 degrees then by all means blow downward. The cooling will be welcome. ;-)

    But only on Tuesdays and Thursdays, after which it's best to alternate direction every 12 hours to keep the air fresh :coolsmile:

    Don, The updraft of a ceiling fan is much less breezy feeling.

    Now that said, I want you to realize you left out a lot of variables. There's the kind of house, Which way the house faces, number of windows, color of the paint on the walls, married or not married, coriolis effect in the room, type of wood being burned, holtzhasen in the yard or not....there is just soooo many other things to consider when determining the direction of the ceiling fan.

    If you take into account all possible variables....I say the ceiling fan in Spikes living room needs to be running backward... your's is impossible to determine at this point...better have us stop by for some analysis and feed us Pizza and beer :)

    My downstairs fans are always set to pull up (reversed) to kind of mix the air, and avoid the direct breeze. However, the big upstairs fan is always set to blow down. This way it pulls air (warm or cool depending on the season) from the downstairs via the foyer and stairwell. Actually works pretty well.

    To make sense out of this, first one has to realize that Mother Nature makes warm air rise. Then, determine what you want to do with the fan: heat or cool. That's all it can do, except maybe dry out some road kill faster.

    This is what works for me and why:

    To heat in winter: Run the fan on low pulling cool air up. This assists Mother Nature by supplementing the natural convection cycle (warm air rises to the ceiling where it cools then returns to the floor along the walls) and helps warm the room faster than no fan allowing warm air to accumulate at the ceiling.

    To cool in summer (below 90* F, low humidity): Run the fan on low pulling cool air up. But now, to let warm out of the house and pull in cool air , open upper and lower windows.

    To cool in summer (above 90* F, high humidity): A. Sit directly in front of a small accessory fan on medium blowing at you. Get a cold drink. Enjoy. Now, swab yourself with a wet towel. The moving air cools your skin as it evaporates. B. Sit in a cool tub, or lake, with a cold beverage of your choice, with a friend - but don't get too close to their body heat. C. Sail "to weather" in the rain, naked.

    Aye,

    Dylan:

    In the Southern Hemisphere, their summer is our winter and cool air rises, so, I recommend you reverse all you do here in the Northern Hemesphere to keep comfortable.

    Oh, food still enters the body via your pie hole though...

    Aye,

    I had read that if you have a high ceiling (I forgot the number) you should always have it on down. I leave our on down and at the fastest setting. You feel the hot air being pushed right down at you.

    Kevin:

    If this is what you like, it's OK. What ever blows your hair back...

    But my experience with that is, after a while, head and shoulders feel the warm breeze but the floor (not to mention my feet) stay colder than helping with the air's natural convection cycle by having the fan slowly pull air up.

    My understanding with a high vault ceiling (thus more cu ft of air), one measley fan blowing warm down isn't going to cut it (except to do what I've experienced above); rather, assist Mother Nature by pulling air up works best over time.


    Aye,
    Marty
