I wasn't aware that the ash would etch the glass. That's the highest I've had my stove , 525,,, at that temp that baby is throwing out some serious heat...QuadraFire 5700 I had would get the room to 72,,, the Fireview has had it up to 79 plenty of times, not even going over the 525 mark.... People thought the Quad was going to out heat the fireview,, because the fireview having a smaller fire box,,, not so,,, thing with the stone,, doesn't matter if it's wood or coals the thing is always pumping out the heat.. What's really nice is if you happen to have a bunch of soft wood,,, your still good to go as all that quick heat is being stored into the stones, not pumped out through the steel and immediately lost.
