Due to insufficient draw I’m planning to rebuild the chimney and would like to have your opinion.
I kind of concluded that my chimney is simply too narrow. it has a 18cm diameter and a length of 4m.
The oven has ‘sufficient’ draw with a diameter of only 12cm in the first section.
When I look at some formulas to determine ideal dimensions I get to a diameter of ~23cm with a lenghth of 4m.
Should I simply rebuild with a diameter of 23cm or with a bit of oversize?
Before I’m going to do this investment of mainly ‘time’ im really curious about the opinions of others so please feel free to comment and advice
Thanks
