This may not be pretty but it would be great for heating a big farm house. Claims 200,000 BTUs and really long burn times. Given the size of that firebox, I have no doubt a big custom woodstove would blow the doors off any conventionally manufactured non-cat stove. If I had $$$ and a big property with outbuildings and such, I would be by-passing the traditional stove makers and looking for custom designers to build huge stoves that could take equally big splits.
