We just moved into a 65 year old house that has an oil furnace in the basement. Our hope is to put in an EPA wood stove on the main floor. Ideally it would be set up so we could burn wood when we wanted to but the oil furnace would kick in when the fire died down or when we were away etc. It is a brick chimney with a clay liner. Is this a possibility or would the two interfere with each other in terms of draft, flue diameter, etc.? There is already a hole in the wall into the chimney on the main floor where presumably there was a wood stove in the past. After reading some great info on this site, my thinking is that I could install an insulated steel liner down the chimney as well. Hoping this will work because I have dreamed of having a wood stove for 20 years! Thanks in advance for any advice.
