High Airflow Ceiling Fans - What's the reason for having a reverse button on ceiling fans? Well "they," say that you cannot stand a draft during winter months, but that it is possible to equalize the air temperature by using your fan in the inverse direction. I always wondered why the older ceiling fans did not have a reverse button. Were the people that designed those fans, only too dumb to consider using inverse in winter?
During winter, when you make use of 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. Before the temperature is comfortable at the lower amounts of the rooms, the heat unit runs. But by the time this happens, it'll be quite hot at the ceiling level.
But what if there is a way to get this hot air down to the low levels where we dwell. The heat unit would not have to work long and also the savings on our utility bill could 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 then someone said that the draft produced by the ceiling fans will be too much for winter months. Afterward it will 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.
