My husband and I are planning to put a wood stove in our basement to cut down on propane costs. The house was my grandparents, built in the early 70's. They had a wood burning stove in the basement for one year, after that their sole source of heat was a woodstove upstairs. We are having the chimney checked this month. If the chimney looks good with no cracks, etc. - is it necessary to add a new lining? (Of course, the chimney/fire place store around here recommends new stainless steel lining - $1200 if they install). Any input would be appreciated. Thanks.
