This bark retains loads of dampness and can protect against the Wooden from drying evenly.one Thus, it's best To combine birch with An additional variety of hardwood for a cleaner burn and fewer smoke. Smoke contributes to a buildup of creosote, which happens to be a byproduct of wood combustion consisting predominantly of tar that frequently brings about chimney fires.2

Apple
Beech (American)
Birch (Yellow)
Hickory (Shagbark)

Birch (White)
Cherry (Black)
Douglas fir
Elm (American)
Maple (Red and Silver)
Tamarack
In the bottom heat-Power class, each wire of Wooden makes about the exact heat as 100 to 150 gallons of gas oil:
Alder (Crimson)
Aspen
Cedar (Red)
Cottonwood
Hemlock
Pine (Lodgepole and White)
Redwood
Spruce (Sitka)
Ensure Your Wood Is Dry
