Hello,
I am planning on purchasing a chimney cleaning brush for my furnace chimney. It is brick, with terra cotta lining (original), 50 years old..
The lining measures 6.5 inches across, measured at the roof
Should I purchase a 6" or 7 " brush (there are no 6.5 inch brushes.
I get the impression from researching, that this is considered a 6" lining, so a 6" brush is the way to go. Am I correct ?
Also, would you recommend metal or plastic (polypropylene) ?
And, bonus question, there is no cap, never has been. Some people say that is fine, as the terra cotta and brick will absorb the minimal rain that enters, others say that a cap is essential.
Opinions ?
