This bark retains lots of moisture and might reduce the Wooden from drying evenly.one Hence, it's best to mix birch with Yet another type of hardwood to get a cleaner burn up and fewer smoke.

Cherry (Black)
Douglas fir
Elm (American)
Maple (Red and Silver)
Tamarack
In the lowest heat-Electrical power category, Each individual twine of wood generates in regards to the identical warmth as one hundred to one hundred fifty gallons of gas oil:
