What makes the best firewood?

Reading Time: < 1 minute

Pound for pound, what is the best firewood? Actually, they’re all the same.

“The main variation between different species is the tree density, which means they have different calorific values (amounts of heat) per volume of wood,” said bioenergy/agroforestry specialist Toso Bozic. “A cubic foot of air-dried white birch weighs about 16 kilograms, while the same volume of white spruce weighs about 11 kilograms.”

The other difference is coniferous species such as pine and spruce contain more resin and that can create creosote buildup. To avoid creosote buildup, ensure there is enough oxygen so the wood is completely burned.
