It's HOT, so I thought run the ceiling fan so the cool air comes across
the stone flooring and moves by me to be sucked up into the ceiling fan -
so I feel cooler. Fan is set to move air UP
Earlier I thought run the fan directly onto me gently moving air straight
at me, which is DOWN. But when I did that, after 10-15min felt hotter in
Just saw one of those home shows, says in winter run the fan to move air
UP so the hot air moves along the ceiling and down your walls. And, in the
summer run your fan DOWN, with NO explanation, except claiming that lowers
your temperature 4-5 degrees [which is impossible in a CLOSED system] and
save up to 40% on air conditioning [what planet do THEY live on?]
So my question is WHICH way is this !@#$#@ system designed for? UP or DOWN
air in the summer?
The instructions for my Hunter suggest blowing v(down arrow) in winter, to keep heat closer to occupants, and ^ in summer, to lift heat up. Those instructions are for a 12" or longer shaft betweem the ceiling and the motor turning the blades.
For my fan - a flush 'ceiling hugger' - instructions are to run v in summer, since there is insufficient clearance for fan to create updraft.
AZ housing is noted for these fans. We have eight laced throughout the
house. Three speed settings, two chains, one for fan one for light, and
always two switches on the walls for each fan, and a 'direction switch' on
the side of the housing, requires a ladder to get to that is very
intelligently mnemonic, slide up air moves UP, slide down air moves DOWN.
noiseless critters, too.
Wow, you seem to have a problem with authority. Of course you can use
the fan anyway you wish. The recommendation has nothing to do with your
house, it has to do with your skin. As others have pointed out when it
is warm a slight breeze can feel good, so the fan is set to blow down so
you can feel it. In the winter when it is cool you don't want to feel
the breeze, so set it to up. By the time the circulation reaches you it
is greatly dispersed and you don't feel the cool air so much.
My bed is right under a window and I tried adding a plastic film to seal
off the draft. But that only worked so well. I tried adding some
cardboard as layers of insulation behind the blind and still felt a cold
draft. Turns out I was reducing the heat flow through the window, but
that was not the full problem. The air by the window would still get
cold, but since it got cold slowly it fell slowly still lowering
temperature significantly by the time it fell on my bed. It took a 3/4
inch sheet of Styrofoam tightly fitted to the window before I could
sleep in that bed. This was a cold winter here and that draft was
unbearable! It only takes a very little air flow to create a very
noticeable draft in the winter because the air can be rather cold. That
is why you want the fan blowing up if at all in the winter. I turn mine
off in the winter. I don't think it changes the electric bill
noticeably one way or the other or the comfort in the room.
Mine cost $40 at Home Depot and doesn't have all those fancy features;
3 speeds, no light, no direction. It is quiet. In our climate, we
probably use it 5 or 10 nights per year, for the rare heat wave.
Ceiling fans are impressive. They seem to last forever.
I did tie it into the ceiling real good. Nothing wrecks your sleep
like a fan falling on you.
Sounds like you have an experience with falling ceiling fan on you?
I have 3 of them fancy ones on top floor of the house. Very seldom use
them. Today it is VERY hot(for us at least), 30.7C in my front yard.
30C temp. here is not usual. Rather -30C is usual in winter, LOL!
30°C doesn't sound so bad to me. I like the 30°C days. It is the 33°C
days like we've been having when it starts to be a bother. This weekend
should be nice though. High around 30°C, low around 14°C at night.
Nice sleeping weather.
Went there, waited ...and waited ...and waited, forgot what it was all
about, couldn't read the tiny little words, so gave up cursing and
swearing under my breath to return here ready to lambaste your reply when
upon rereading, realized what that image was! then, LOL!
Plus, the images had an unusual coordinate system for showing those
spatial diagrams. Had you not shown me those images, I NEVER would have
thought of using that type of presentation to potential clients for
showing accuracy of our proposed position-location system in that simple
manner, THANKS! See, there's a reason for everything!
The theory is to move the hot air from the ceiling down to the living
space in the winter. Depending the use of the space, summer may
require up or down. If air conditioned you can get away with keeping
temps at least 4 degrees warmer if you keep the fan running down
because the light breeze helps cool.
Running the fan UP draws the cool air from the floor up to the ceiling
and circulates the air across the ceiling to spill down the walls.
Doesn't work as well with "architectural" ceilings.
I just put 2 70 inch fans in the office - 6 speed - running down on
4th speed -13 and 15 foot ceilings with architectural features -
