Ceiling fan question, large room.

I heat an 1800 SF shop with a woodstove. The shop has 14 foot tall ceilings. In the shop I have a small mechanical room that the stove backs up against so the stove is central but against a wall. I am getting ready to put up the ceiling and am pondering the placement of a ceiling fan that is intended to maximize the movement of heated air to all parts of the 30x60' shop. I have noticed that there is a strong plume of hot air that rises vertically from the stove.

So would you place the ceiling fan right on top of the stove, just barely missing the chimney pipe with the intention of intercepting that plume and either accelerating it or blowing it back down to the floor. Or option 2, would you place the ceiling fan far enough away from the stove that the fan can only mix the room air but not blow directly onto the stove.

In my house I like the central fan to provide highest comfort and mixing without air currents. In the shop, I am trying to maximize heat distribution.

The fan(s) will be the industrial 60" three blade type that are supposed to make 10,000 CFM.

I would put a pair of conventional fans instead of one large one. The purpose in a large space being to create a convection loop with one blowing up and one blowing down.

One is going near the stove and I can't decide whether to put it right on top of the stove or in the center of the area just in front of the stove.

I don't believe that you need two fans in opposite directions to create a flow. The fan itself creates that convection loop by sucking from one side and blowing to the other. These fans will almost certainly blow down all the time and their airfoil blade design makes them directional.

When I said "one is going near the stove" I meant one of the fans. There will be three. equally spaced down the long dimension so twenty feet apart. It's that one by the stove that I can't figure out exactly where to place. RIght above in the rising heat plume or more central to create a stir.
