may damage the fan motor of the vent fan by sucking air in a line that is already powered
Dallas wrote:In looking further at your picture, if i understand your thoughts correctly, the air from a vent by the table lamp, would have a pretty "short trip", to get headed back down the stairs. The heated air won't be in the room very long and it won't get very far from the vent, before heading downstairs.

As far as it blowing to much air why not just connect it to a variable speed control so you could just dial it in the way you want it. I would think you would need more air being moved during the coldest days and less on the average normal temperature days.
