That stove has been burnt really hard you can see allot of distortion on the sides as well the op said coal was hardly ever used so i dont think that had much to do with it i think it was just burnt out probably due to not very good design and not the best quality materials

OP said coal was used "A few times." Didn't quantify "A few" nor say how long or how hot. Coal burns hot as well as acidicly. I can go with you on poor quality and design but I stand by my comment on coal being causal.
I can agree with that but it was made as a coal stove as well so it should be able to handle it as well. I would expect to see that damage after 15 or 20 years but 5 years is pretty bad

They said no cold air return voids warranty. I burned coal three times. I think the thickness of the steel has a lot to do with it. Back wall 7 gauge and side walls 5 gauge. Any suggestions for an alternative add on furnace?
What specific model furnace is this? Can you provide a full exterior shot? Is the return blocked off or just pulling air from the basement?
yea it says very specifically that you need a cold air return and gives you the required size. As long as the return is not blocked i don't see why it would cause that damage but it clearly voids warantee
brother bart, the thickness of the box was given to me by the manufacturer. Sheet metal, no chit, that is what it feels like. I don't think my basement ever reached the point that the air was to hot. The floor vents going upstairs would put out very nice heat. In the basement it was comfortable, I would say between 60-65. Lesson learned. An education is expensive. So lets hear some suggestion for a replacement unit.
That stove is suffering from the same thing that did in my big Sierra insert. Hot stove and slamming the butt end of splits and rounds into the back wall of the firebox. Mine was 1/4" plate so it took a little longer.
5 gauge is 0.21 inches thick. Thicker than your stove's firebox BB.
And steel is sheet until it exceeds 6mm which is 0.24 inches. So our Englanders are sheet metal too except the top plate which is supposed to be 0.25". Or is it? See photo.
My BK is really thin, looks to only be 0.125" on the sides.

he said his was 1/4" which is .25 more than the .21 but both are fine i am sure. And yeah that looks like 3/16 to me but cant tell for sure with the edge roundover
Yes but i still think thicker is better

When I go back and read his post, he clearly said "Back wall 7 gauge and side walls 5 gauge."
Yes, thicker is better but even thin sheet stoves are very common.
ahhhh ok you are correct my bad. Honestly it has as much if not more to do with the quality of the steel as it does the thickness.
