Small Hallway Ceiling Fans - I wondered why the older ceiling fans did not get a reverse button. The people that designed those fans, only too dumb to consider used reverse 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 assemble at the ceiling level and gradually work its way down toward floor level. The heating unit runs until the temperature is comfortable at the lower levels of the rooms. However, from the time this occurs, it'll be very hot at the ceiling level.
However, imagine if there was a strategy to get this hot air down to the low levels where we live. The heating unit wouldn't have to work as long and the savings on our utility bill could be substantial. This mixing would basically equalize the temperature at ceiling and floor levels, meaning the heat wouldn't be wasted keeping the ceilings warm.
But someone said the draft produced by the ceiling fans would be too much for winter months. Afterward it's going to come down until it hits the floor. Now it then back up to the ceiling fan and will go back in toward the centre of the space.
