Comparing Firewood by Heat Vitality
Distinctive firewoods may be categorized by the quantity of warmth Electrical power they produce for each twine of wood. The ideal firewoods offer the heat-Power equivalent of 200 to 250 gallons of fuel oil.4 These contain the next:
Apple
Beech (American)

Purple oak

Birch (White)
Cherry (Black)
Douglas fir
Elm (American)
Maple (Crimson and Silver)
Tamarack
In the lowest heat-energy classification, each wire of wood creates in regards to the very same heat as a hundred to one hundred fifty gallons of fuel oil:
Alder (Red)
Aspen
Cedar (Pink)

Hemlock
Pine (Lodgepole and White)
