What happens when air from the ceiling fans hits the ceiling in a room with a sloped ceiling? If the ceiling fan is centered in the room, it would be basically half way up the slope. So wouldn't all the air go directly up the slope from where the ceiling fan is mounted? What about the other half of the room? What happens when the room is large? Will the force, coming down the walls, still be enough to get this warm air to the floor, especially when the ceiling is two stories high? What happens when ceiling fans are in a room with a two story high ceiling, which is open to the second floor level of the home?
This fact is not lost on the ceiling box manufacturers that are producing ceiling, outlet and junction boxes that are quick to install and are made of plastics that require less and less labor to install properly. This has gotten to the point that there is now a lighting box that only needs to be pushed onto a wooden stud for it to be secured; no fasteners are needed at all. The ceiling fan manufacturers however may not be keeping pace with the trend in ceiling box installation practices. They advise the consumer of their products to reinforce or replace the existing fixture with a fan-rated ceiling box which is prudent, though are the consumers heeding their installation directives?
So wouldn't this be much more efficient than using reverse, especially in the scenario where the ceiling is two stories high and open to the second floor? But what about the draft? I say just run the ceiling fan at a low speed or the highest speed that you can tolerate and still be comfortable. Could reverse on ceiling fans be a marketing tool to sell fans in winter? You decide. But I do not think that the old folks overlooked something as important as this. I think that they used what was most efficient. I agree and my ceiling fans always blow down, winter and summer.
