I can find tables of average BTU's per unit for most species of wood - I
burn red and white oak almost exclusively .

A couple of critical variables are difficult impossible
to factor in to a calculator - what type of structure ?
- old & drafty - or new and sealed ? somewhere between ?
How warm do you like to keep it ?
Also - if the structure is open to the howling winds -
it will affect things as much as degree days.
I would ask a few wood-burning neighbours before trusting
a guess-work calculator.
