no clue... it would in fact add heat maybe lots of heat. as soon as you get far enough along to where you can build i fire. do a test burn and see what temps you get. if you need more use the hair dry into an air vent and see what happens. you can always add a damper to the fan to control it if needed. you can use scrap for a mok up. i didn't come up with the fan idea. i just found the fan.
