Nest Thermostat Ceiling Fan - What exactly 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 did not get a reverse button. Were the people that designed those fans, just too stupid to think of using inverse in winter?
The heating unit runs until the temperature is comfortable at the low levels of the rooms. However, by the time this happens, it will be quite hot at the ceiling level.
However, imagine if there was a strategy to get this hot air down off the ceiling, to the lower levels where we reside. The heating unit wouldn't need to work as long and also the savings on our utility bill could be considerable. This mix would basically equalize the temperature at floor and ceiling levels, which means that the heat wouldn't be wasted keeping the ceilings warm.
But someone said that the draft made by the ceiling fans would 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 flat in most ways until it hits the walls. Until it hits on the floor, then it'll come down vertically. Now it's going to go, toward the middle of the room, back in at floor level and then back up to the ceiling fan.
