Allen Roth Ceiling Fan Globe - What's the reason for having a reverse button on ceiling fans? Well "they," say that you aren't able to bear a draft during winter months, but that you are able to equalize the air temperature by utilizing your fan in the inverse direction. I wondered why the ceiling fans that were older did not get a reverse button. Were the people that designed those fans, just too stupid to think of using inverse in winter?
During winter, when you employ the central heating system, the warm air coming from the registers, in each room, will naturally rise and because the registers are up high already, the hot air will build in the ceiling level and gradually work its way down toward floor amount. The heating unit runs until the temperature is comfortable at the low levels of the rooms. But by the time this happens, it'll be quite hot in the ceiling level.
But what if there is a method to get this hot air down off the ceiling, to the lower levels where we reside. The heating unit would not have to work long as well as the savings on our utility bill may be significant. This mixing would basically equalize the temperature at floor and ceiling levels, meaning the heat would not be wasted keeping the ceilings warm.
But then someone said the draft made by the ceiling fans will be too much for winter months. So someone else said "well, let's just reverse the ceiling fans and allow the air blow up until it hits the ceiling and then it will go horizontal in all directions until it hits the walls. Then it'll come down until it hits the floor. Now it then back up to the ceiling fan and will travel, toward the centre of the space, back in at floor level.
