Newbie here, I have been reading some posts and this place has a load of information. The make of the stove in the pictures attached is by "Elco", but have found no information about it.(Note: the damper plate chain is an add on after the original was replaced) I hear this stove is more than likely a prefab, in a masonry chimney with a 8" square clay liner. The house butts right next to the chimney, built in the late 80's. I wanted to try and see how it was built in and took the face plate off. I was hoping I could just put an wood insert in, but looks like my options maybe limited. I was reading in another post about the kozy heat z42 option. I'm curious what my options are, if anyone has taken one of these out completely (if possible) or modified it a way so that another, more efficient, stove can be put in. The size of this stove opening is 44" wide by 30" tall. I want to run the stove 24/7 to heat a 2,000 sqft area, or the biggest stove I can fit in there so it doesn't look stupid. Thanks for the help!
