It's the Vigilant II model 2310 in current production I think. It was the redesigned coal only model with the ash pan in the ash drop compartment added below the lip of the double doors. With coal, mine is rated at 50,000 BTU/hr. It's a tad small for all out use of coal for heating my house
but does do the majority of the heating. I'll eventually get to that level.
I think that since your are burning wood in your Vigilant the output will be lower than 50k due to the lower BTU content of the fuel. There's another thread about calculating heat output of your solid fuel stove
in another thread. It might get you close if you can't get a quote from the literature.
