Drolet DB03060 Wood Stove Utilisation, Average Energy Yield of ONE AIR Dried Cord of CUT Wood

WOOD STOVE UTILISATION

Your heating unit was designed to burn wood only; no other materials should be burnt. Wastes and other flammable materials should not be burnt in your wood stove. Any type of wood may be used in your stove, but specific varieties have better energy yields than others. Please consult the following table in order to make the best possible choice.

AVERAGE ENERGY YIELD OF ONE AIR DRIED CORD OF CUT WOOD

	Wood species	Energy yield
		(millions of BTU/cord)
	Oak	29
	Sugar Maple	28
High energy yield	Beech	26
	Yellow birch	25
	Ash	24
	Elm	23
	Larch (Tamarack)	23
	Red Maple	23
Medium energy yield	Douglas red fir	23
	Silver birch	22
	Alder	18
	Poplar	17
	Hemlock	17
	Spruce	17
Low energy yield	Pine	17
	Bass	16
	Fir	13

IT IS EXTREMELY IMPORTANT THAT YOU USE DRY WOOD ONLY IN YOUR WOOD STOVE. The wood must have dried for 9 to 15 months, such that the humidity content (in weight) is reduced below 20% of the weight of the log. It is very important to keep in mind that even if the wood has been cut since one, two or even more years, it is not necessarily dry, if it has been stored in poor conditions; under extreme conditions, it may even rot instead of drying. The vast majority of the problems related to the operation of a wood stove are caused by the fact that the wood used was too damp or had dried in poor conditions. These problems can be:

•ignition problems

•creosote build-up causing chimney fires

•low energy yield

•blackened windows

•incomplete log combustion
