My husband and I bought an 80-year old house and would like to install wood heat. The previous chimney was sheetrocked and a staircase (aka, flammable wooden boards) built up against it. We also have a Vogelzang Boxwood cast iron stove, which claims it should be able to heat the bottom floor of our 1 & 1/2 story house. This will be entirely DIY project, because of our budget. We are not sure what is the safest and most affordable way to go about installing a chimney. We thought of three options: Our favorite: Use the existing chimney. A sweep told us it might still be okay, even with the flammable materials against the brick, if we use extra insulation. But I don't know how much insulation would be needed. Back-up option: Use a metal chimney kit, but it would have to go through both stories, and location of the stove below becomes more problematic. Last resort idea: We eventually plan to build a room onto the house, in a couple years. If the other options aren't feasible, we could build a chimney into the new room. But, this is a last resort because the location would be de-centralized, and I'm not sure it would keep our plumbing warm. We might have to go out and buy a more powerful stove if we did this. Can anyone help, and tell us what we need to do regarding the chimney? Is the sweep right - we can still use the chimney if we extra-insulate - and if so, how much insulation would we need, and what type? Neither my husband nor I are experienced with major carpentry work, and we don't want to burn the house down, so any advice would be appreciated!
