I had a massive chimney fire (my own fault really) back in March or so... Well, it cracked the liner to where the chimney unusable (the handsome firemen told me so) to use the woodburner again. Estimate from a chimney place? To "sleeve" the inside? $1800. OR I can put double walled - stainless pipe in as a "kit" from the same people for $700. My question is this: the chimney is still in good shape - the LINER is cracked/split/damaged (I haven't actually gone up there and looked at it, btw - the handsome firemen told me this). I want to know why I can't put 8" (my woodstove's flange size) black pipe from the woodstove up through the chimney, securing it so it stays in the CENTER of the existing chimney - to minimize the heat from the stove pipe. I've been told the black pipe will rust out and fail almost immediately. My Fisher stove doesn't have a baffle, btw. It would be much cheaper (my pipes for the water to the house have also failed so I have to come up with at least $1,000 to repair it) and I could get by and have a warm house (my furnace quit YEARS ago so I have few options). The specs? It's a single-story ranch home. The chimney is in the center of the house (keeps warm), and is a straight shot from the woodstove flange to the top of the chimney. Thoughts?
