I recently bought a 2 story 2900 sq ft home built in 1892. There are two fireplaces, one downstairs and one upstairs, which share one chimney. There are two more chimneys that each have a hole (flue vent?) at about 7' or 8' feet, one on the first floor and one on the second floor in each chimney. There is a fourth chimney which actually starts about mid-way up a wall in one of the second story rooms. From what I gather, the fireplaces were for coal, they're very shallow and small. As for the other chimneys, I guess they were for coal or woodburning stoves. I would like to use wood or pellet burning stoves where the three chimneys are, and I'd like to use the fireplaces, too, if possible. I live in Texas so I think coal is somewhat unavailable. My question is, can I modify the fireplaces somehow so I can use them for wood? And what needs to be done to the other three chimeys in order to use wood or pellet stoves? I'm assuming chimey liners should be installed in all four chimneys if they are too be used. Any information would be greatly appreciated.
