Do Ceiling Fan Dust Filters Work - What's the reason for having a reverse button on ceiling fans? Well "they," say that you CAn't bear a draft during winter months, but that you can equalize the air temperature through the use of your fan in the reverse direction. I wondered why the older ceiling fans didn't get a reverse button. Were the people who designed those fans, simply too ignorant to think about using reverse in winter?
During winter, when you use the central heating system, the warm air coming out of the registers, in each room, will naturally rise and because the registers are up high already, the hot air will assemble at the ceiling level and slowly work its way down toward floor amount. Before the temperature is comfortable at the low amounts of the rooms, the heating unit runs. However, from the time this occurs, it will be quite hot at the ceiling level.
However, what if there clearly was a method to get this hot air down off the ceiling, to the lower levels where we live. The heating unit would not have to work long and the savings on our utility bill might be considerable. This mixing would essentially equalize the temperature at floor and ceiling levels, meaning the heat would not be wasted keeping the ceilings warm.
But someone said the draft produced by the ceiling fans would be too much for winter months. So someone else said "well, let us simply reverse the ceiling fans and let the air blow up until it hits the ceiling and then it will go horizontal in most ways until it hits the walls. Until it hits the floor, then it's going to come down vertically. Now it's going to go back in toward the center of the room and then back up to the ceiling fan.
