3.1.5 How to Dry Firewood
Firewood that is not dry enough to burn is the cause of most complaints about wood fireplaces. Continually
burning green or unseasoned wood produces more creosote and involves lack of heat and dirty glass door.
See
Section 5: Maintaining your wood heating system
for concerns about creosote.
Here are some things to consider in estimating drying time :
•
Firewood takes a long time to dry.
•
Small pieces dry more quickly than large pieces.
•
Split pieces dry more quickly than unsplit
rounds.
•
Softwoods take less time to dry than
hardwoods.
•
Softwoods like pine, spruce, and poplar/aspen
can be dry enough to burn after being stacked
in the open for only the summer months.
•
Hardwoods like oak, maple and ash can take
one, or even two years to dry fully, especially if
the pieces are big.
•
Firewood that is ready to burn has a moisture
content between 15% and 20% by weight and
will allow your fireplace to produce its highest
possible efficiency.
•
Firewood bought from a dealer is rarely dry
enough to burn, so it is advisable to buy the
wood in spring and dry it yourself.
•
Drying happens faster in dry weather than in
damp, maritime climates.
•
Drying happens faster in warm summer weather
than in winter weather.
•
Firewood dries more quickly when stacked in
the open where it is exposed to sun and wind; it
takes much longer to dry when stacked in a
wood shed.
3.1.6 Judging Firewood Moisture Content
You can find out if some firewood is dry enough to burn by using these guidelines:
•
cracks form at the ends of logs as they dry,
•
as it dries in the sun, the wood turns from white or cream colored to grey or yellow,
•
bang two pieces of wood together; seasoned wood sounds hollow and wet wood sounds dull,
•
dry wood is much lighter in weight than wet wood,
•
split a piece, and if the fresh face feels warm and dry it is dry enough to burn; if it feels damp, it is too
wet,
•
burn a piece; wet wood hisses and sizzles in the fire and dry wood does not.
