Bathroom Exhaust Fan Condensation

Is there in your world of knowledge, thank you by the way in advance… a bathroom fan that will heat the vented air as it is being pulled out? Thereby preventing it from condensing and collecting in the vent tube. If this magical device exists could you list info on where to obtain one? Thank You again for what you are doing, William

I am not aware of any that will heat the exhausted air, as this would be very costly an inefficient.  However, you could insulate the exhaust duct thereby keeping air inside warm until it exists the building, and lessening the condensation problem.  I'd also use metal ducting instead of the flexible plastic duct for this.
