My sister's neighbor is selling his mid 1980's vigilant wood/coal stove. The stove was purchased new by him in the mid 1980 and has been in use in his home every year since. I went over and looked it over lastnight appears to be in pristine condition. He told me that he each spring he cleans it out and lines it with kitty litter to absorb any moisture during the summer then in the fall he cleans all of that out and lines the bottom with sand to insulate the bottom of the stove. The only reason he is selling it is he is now in his 60's and doesnt want to keep dealing with the wood anymore. My questions on this are: what is a fair price to pay for one of these stoves? I have noticed them selling from as low as 200 to completed restored at over 1200.00 Is it ok to run these into a 6" metalbestos flue? I have straight up flue right now from my current stove, that runs straight up and out of a two story house 20' I am guessing. Are these safe to run any more my neighbor indicated that they are known for a lot of chimney fires. I am currently running the smallest regency out there with a 1.3 cube foot burn box and really am looking to upgrade to a large burner with extended burn times. What are the estimated burn times on this stove, he told me it normally burns a good 8 hrs on a fill and usually cranks out so much heat you cant even sit in the same room the stove is in. I have no reason to doubt the seller he seems very honest and offered to dig out all his receipts and original paper work to show me he is the type to save every piece of paper.
