My concern with these multi fuels is that they get over fired with wood because people try to heat a large space with them. I looked at the new Ashley type a few yrs ago when I was thinking about coal and found them somewhat light for my application. You state this is your 3rd wood stove, this should be a red flag. My 2 coal stoves that I use will last my life time if used properly, 1 is already 30 plus yrs old and I think my Vigilant is 10 or so yrs. If you could afford a used coal stove, there are many in your area. Now about the King, if it was used without fire bricks chances are it won't handle a stove full of coal. Blacksmiths forge metal with a coal fire and a stove that has been compromised could be very dangerous. Please do a search in the upper right corner on how to start a coal fire and put a pot of coffee on. I don't want to seem negative but your safety is very positive! Mike.
P.S. Operating the King should require a couple C.O. detectors in the house
Also start a new thread if you like about your stove and the response will be better!
