   Make sure you balance the fan blades good before powering them up full speed. Otherwise that 12 foot downrod will be a whipping and wobblin'

   Remember a professor for mechanical systems remarking about the inefficiency of ceiling fans.  They're often an automatic resort to moving air in large spaces (i.e., church sanctuarys), yet there would need to be so many of them to notice any effect that their cost would override any energy savings.

   i might question whether a single ceiling fan arranged as you describe would really be worth it.  Roughly centered in a 22' high space, it wouldn't move heated air above or cooler air below.  A floor fan might be more noticable for cooling, and a space heater/radiator for heating.

   You just need a big enough fan: http://www.bigassfans.com/catalog.phpThe smallest they sell is 6 feet in diameter.

   i want one cause nobody else has one. so if i buy the 8 foot model,where do i get a fan rated box for 175lbs!!!!!!thats there small one.the one i relly want is 24' but i would have to enlarge the shop by 8". heck i'd probably have to put in more trusses to hold the weight. larryhand me the chainsaw, i need to trim the casing just a hair.

   That's why you install those hurricane straps.
