I am in the beginning process of finishing my garage and since it is not attached to the home heating system (and it would be a great cost to do so) I would like to install a ceiling fan that provides heat. The garage is a tight 2-car garage at 19'-4"x18'-6". Everything I seem to read says that one ceiling fan will heat a 20'x20' room. Would this be correct to assume that 1 fan would be sufficient for my space? Has anyone installed a heating ceiling fan? I would be very interested in your input.
