White birch, paper birch and gray birch firewood burns good but doesn’t last long. It has low to medium heat. White birch doesn’t dry well until it is split because the bark seals moisture in so well. And it will rot fairly quickly if it is not cut split and dried. It tends to rot (or pooches) from the inside out.
Yellow birch and especially black birch are higher in BTU and usually considered to be the best of the birches for firewood. Black birch is more comparable to oak in BTU and density.
Birch is usually easy to cut and split and is very abundant in the northeast parts of the US and western Canada. In many of the more northern areas birch is one of the few hardwoods and in some cases the only hardwood available.
