Nice! You ever get your hands on any hardwood there? That white birch is like chit thru a tin horn here for heating, I'm sure it's the same for you, Yellow or black birch, now that's a different story here. Stayin warm is the deal no matter what the wood!
Obviously a different kind of birch you have, looked like the white paper birch we have here, different part of the globe....and wood....whoops. It all makes heat, hopefully when you need it, I'm burnin hemlock right now.
