You have stated that ceiling fans should rotate clockwise in winter.
Does this apply if the heat is forced into the room through vents in the ceiling?

I did not receive an answer to my question asked yesterday.

I have been informed that ceiling fan rotation should be clockwise in winter.
(question) If my heating system forces warm air through vents in the ceiling, does this still apply.

The reason your question cannot be answered is the fact of blade angle. It is not the rotation you are looking for but the direction of air flow. Usually you draw air UP for heat. This will allow the fan to raise the cool air to the ceiling then mix with the hot air at ceiling then the blend of air will come down the walls back into the space. If you blow air down in the heat mode you will create a draft where you are sitting and be uncomfortable.

Whichever rotation you need to use to be comfortable is your decision.

My vents are in the ceiling and this is what I use. Now when you really get down to it the difference is not that substantial anyway. All you are doing is moving air to blend. Now if you have 30 foot ceilings to worry about that could be a different subject but the average home there is not much difference except as already mentioned for comfort. I suggest a variable speed control since running the fan at slower speeds usually work well.

Counter clockwise pushes the air down cooling for summer. Clockwise pretty much circulates the air. We keep ours on low in the winter and our heat comes from the ceiling.

Ceiling fans should be used in downdraft mode in the summer (CCW). In the winter you can use either updraft or downdraft mode (CW or CCW) depending on your preferences, it REALLY doesn't make much of a difference unless you feel a draft. I keep my fans running CCW in the winter and just set them to low.
