When the alarm clock rings at half past five in the morning, the master chimney sweep Michael Hügel heads off to his Franconian district of Iphofen near Würzburg in his Citan 109 CDI. The daily business of a chimney sweep awaits: sweeping, cleaning and measuring. This is important for the environment and even saves lives. Because if the smoke no longer flows up the chimney properly, it can cause carbon monoxide poisoning. That is what makes the chimney sweep’s work so important today.
