New to the forum... After we froze our butts off during Hurricane Sandy, we're a wee bit closer to installing a wood stove (or two). Here's the situation: -Old stone house, fireplaces (unlined stone flues) on each end. There is an addition on one end, and that's the end we're talking about here. Looking at two options: - 1. Poke a hole through into the flue from the addition side, line the flue, and install a wood stove. Leave the fireplace as is - with a newly lined flue -[that would be two flues inside the existing stone flue]) and functioning. - 2. Same as above, except put a second wood stove in the fireplace. The opening of the fireplace is 44.5"w x 39"h. (1735.5 square inches). The existing stone flue is fairly large (I don't have the measurements on hand) and straight. Looking at the 1/10 ratio rule for flue/fireplace opening, am I going to have trouble accomplishing option 1? Your thoughts? SS vs. poured? Cost? DIY?
