I'll get some pictures of what I am using.
Its basically a converted coal stove. I don't really know if its "converted" but the old man burnt coal in it, then wood later on. It works great.
It basically looks like an over sized 55 gallon drum with a cast iron door for the burn box and a cast iron door for the ash bin. Then it has 4 holes in the top for the radiant heat to push through the duct work.
I can't find a single thing on the internet about it. Stamped 21st Century, has some dates and patent numbers on it. According to the older guys in town all the homes had one of these installed that were build from 1913 to 1930. They were put in the basement then the house was built over it. Its so huge you'd never get it in or out of there.
Anyone ever tried one of these?
I see them at fleamarkets and tag sales. They are under powered for logs more than about 10" in diameter depending on the species. Good Luck, Rick
