We live in an old 2 story farm house and have a woodstove that is attached to an unlined chimney in the center of the house. I know this is not safe and would like to sleep at night! I am not sure what I need to do. I have researched the topic and it some say to throw in a insert, some say it's not safe to put an insert in a unlined chimney. Any suggestions? Can I install a SS liner from the roof down and call it good or will I still be worried about chimney fires? THANKS! I have lurked here for a year now and have gained much needed knowledge!
