Combination wood/coal stove? One word...compromise. Can't do both well with one stove. Also, folks who think they want to burn both have never learned to burn coal. You've got hot water baseboard. A coal boiler is a no brainer.
I read your post in the other thread about this stove and after reading your re-build thread of your riteway 37 you seem to know a lot about these stoves and appreciate your opinion, BTW nice job on the 37. I'm going to stop by the dealer and take a picture of the firebox for anyone that is interested to comment on them.
