Hi everyone. I just bought a Vigilant 1a that's in pretty good condition ($290). I have yet to hook it up, but I plan to do it in the coming weeks (and I'll have a lot of questions after that, I'm sure). My biggest question right now is this: I live on an island where a lot of building takes place and there is a continuous supply of framing ends and scrap wood at the dump. During the cold months, the dump is open to picking, and I can likely pick up enough free combustible material to heat my home for free each winter. The home we first rented when we moved here had a small wood stove and the owner encouraged us to burn scraps of pine, cedar and mahogany in it. So is it worth it? How often will I need to clean my chimney? (I'm not even certain how to clean my chimney) Or am I, pardon the pun, playing with fire and should bite the bullet and buy a cord of seasoned wood (which costs a lot here on Nantucket)? Great forum. I've already learned a lot just by reading old threads. G.
