In some ways I liked the 55 gallon drum stove a little more than the real stove I have now. It was larger and I could fill it twice a day, it never burned out. The stove I have now is probably doing a better job but I have to fill it 3 or 4 times; morning, after work, evening, and if I get up- once in the middle of the night.
The drum stove I had was a double barrel over under deal, and perhaps let the exhaust get too cool as I'd have to brush the chimney a few times a season, I've brushed the same chimney no more than once in 2 seasons now with the Fisher stove. Seems like I use the same or less wood with the new stove as well.
What I'd really like to have is an indoor wood fired boiler, a "Wood Gun" They get good reviews on some of the wood heat forums but from what I can tell do take some tuning and understanding to operate correctly.

One day when I have more time and can afford to, until then the indoor wood stove works decent.
