Universal Sloped Ceiling Fan Adapter - I always wondered why the ceiling fans that were older did not have a reverse button. The people who designed those fans, just too dumb to think of used inverse in winter?
During winter, when you employ 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 in the ceiling level and gradually work its way down toward floor level. The heating unit runs until the temperature is comfortable at the reduced amounts of the rooms. However, from the time this occurs, it'll be very hot in the ceiling level.
However, imagine if there was a strategy to get this hot air down off the ceiling, to the low levels where we reside. The heating unit wouldn't have to work as long and the savings on our utility bill may be considerable. This mix would essentially equalize the temperature at ceiling and floor levels, meaning that the heat wouldn't be squandered keeping the ceilings warm.
But then someone said that the draft created by the ceiling fans would be too much for winter months. So someone else said "well, let's just reverse the ceiling fans and let the air blow up until it hits the ceiling and then it'll go flat in all directions until it hits the walls. Afterward it's going to come down vertically until it hits the floor. Now it then back up to the ceiling fan and will travel, toward the center of the space, back in at floor level.
