I really like the idea of using a dual bell system, where one is small and steel and the other’s large and masonry. The thing that triggers me to build/add to a fire is feeling cold, so having quick response is nice. But then of course you want heat mass to avoid dumping all of the extra heat out the chimney. If my Hearthstone stove ever goes out, I’d like to build one of these.
