Light Switch For Harbor Breeze Ceiling Fan - What exactly is the reason for having a reverse button on ceiling fans? I wondered why the ceiling fans that were older didn't have a reverse button. The people that designed those fans, simply too stupid to think of used inverse 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 build at the ceiling level and slowly work its way down toward floor level. The heating unit runs before the temperature is comfortable at the lower levels of the rooms. But from the time this happens, it'll be quite hot at the ceiling level.
But imagine if there is a way to get this hot air down to the lower levels, off the ceiling where we live. The heating unit would not need to work long as well as the savings on our utility bill could be significant. The temperature would basically equalize at ceiling and floor levels, meaning that the heat would not be wasted keeping the ceilings warm.
But then someone said that the draft developed by the ceiling fans would be too much for winter months. So someone else said "well, let's simply reverse the ceiling fans and allow the air blow up until it hits the ceiling and then it is going to go horizontal in most directions until it hits the walls. Until it hits the floor, then it's going to come down vertically. Now it then back up to the ceiling fan and will go, at floor level, back in toward the middle of the area.
