If you have an incurable draft problem, we have the solution. Lindemann Chimney sells exhaust fans that ensure proper draft and prevent smoke and odors from filling your home. Exhaust fans are mounted at the top of the chimney and literally suck smoke or gas up the flue. The chimney fan is designed to disperse the smoke sideways like a regular chimney cap. Chimney fans also help to reduce the amount of creosote in the flue, while preventing back puffing. We carry Enervex fans, formerly Exhausto fans, the clear industry leader. High temperature exhaust fans are an easy solution for smoking fireplaces, stoves, BBQ’s and more. They will correct an existing draft problem and ensure a perfect draft every fire.
