I have the Vogelzang Boxwood stove and I have been using it since last winter.
One good point is that besides being very inexpensive (got mine for $200) it will crank out probably 50K BTU without over firing the stove although at optimal safe output it has a 3 hr burn time on the very best hardwood. Throw in pine and it will eat it like cotton candy.
I have it rigged up with fans and makeshift duct work to heat my basement and keep the pipes from freezing by directing the flow up the stack chase in the corner of the building.
Last winter my pipes never froze, the basement was toasty and a wee bit of that heat actually drifted up to the 2nd floor bathroom where Iive but no way can it produce output to heat the basement, and the 2nd floor where I live.
I have to use natural gas on the floor I live on.
I have an unfinished basement that has 24" thick stone walls and a cieling that is 3" of fireproof plaster and mesh. For this reason I can overfilre this thing and have no fear of burning my house down.
It will crank out close to 100K BTU wide open but to do so I'm filling it up every hour and a half, dumping ashes daily and absolutely abusing the stove and the flu pipe.
If I keep using it like I do (overfiring it most of the time) it will burn thru my galvanized pipe and probably the stove itself by the end of this winter.
If this stove was not in a basement area that is absolutely fireproof I would not be able to get away with abusing it it the way I do to get the output I want. I even used to toss in big chunks of coal on the zero degree days.
I have been treating this thing as a disposable stove until I get my stoker.
This thing is not anywhere close to a solution to heat a house or a finished area.
If you plan to heat than just the area around the stove then you gotta get a coal stove.
Im about to get an LL Pocono. I will love that 200# hopper giving me a week long burn without overfiring while it heats the basement and the floor Im living on.
