Casablanca Wailea Ceiling Fan Light Kit - What is the reason for having a reverse button on ceiling fans? Well "they," say that you cannot withstand a draft during winter months, but that it is possible to equalize the air temperature through the use of your fan in the inverse direction. I always wondered why the ceiling fans that were older didn't have a reverse button. Were the people who designed those fans, just too ignorant to consider using inverse in winter?
During winter, when you apply 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 in the ceiling level and slowly work its way down toward floor amount. Until the temperature is comfortable at the reduced amounts of the rooms, the heat unit runs. But from the time this occurs, it will be quite hot in the ceiling level.
But imagine if there was a strategy to get this hot air down to the lower levels, off the ceiling where we reside. The heat unit would not have to work long and the savings on our utility bill may be considerable. The temperature would essentially equalize at ceiling and floor levels, meaning that the heat would not be wasted keeping the ceilings warm.
But someone said the draft produced by the ceiling fans could be too much for winter months. Afterward it will come down until it hits on the floor. Now it's going to travel back in toward the centre of the space and then back up to the ceiling fan.
