Question:

A couple of weeks ago- I asked for some suggestions on how to cure a chimney that was filling with water and weeping back into the house. You suggested an insulated insert into the chimney. We contacted the people who sold us the stove and they installed a barometric damper. The net effect is that it sucks air from the room and allows it to go up the chimney to heat it better. The net result is that we can burn our stove hotter...thats good- it is not so hot in the room- thats good too- but best of all- we have a chimney that has enough warm smoke going up it to avoid the condensation problem.



Answer:

Great..installing a barometric helps the airflow up the chimney stay constant- and may allow the water vapor to exit before it condenses..
