I've got a Fisher wood stove - a Mama Bear model, I believe (it's a single door, with the handle on the left side, a screw-driven draft on the left side, and an after-market temperature selectable draft on the right side). I'd like to use some coal I've got around the house as a fuel for it. I can say that as of right now, my plans would be maybe to load a lump or two of it at night in there, or while I'm gone during the day, more or less as a mix with wood. I know that a coal fire can & will be much hotter than a wood fire, so I would be looking at it only as a supplement to what I'm burning now. Again - my only intention is as to burn a little coal along as a supplement to what I burn now. Any drawbacks to this? I'm not able to find anything on Fisher wood stoves, so I don't really know the temperature ratings on these. Also, as an alternative fuel, I am looking for something to supplement the wood I am burning now - mostly hardwood. Anything cost-effective (i.e. cheap) but good? Can't depend on the junk mail to supply with a steady stream this year....... I'd appreciate any feedback on this.
