Firewood is an area where you can have great influence over
how well your system performs and how enjoyable your experience
will be. Quality, well seasoned firewood will help your wood
stove or fireplace burn cleaner and more efficiently, while
green or wet wood can cause smoking problems, odor problems,
rapid creosote buildup and possibly even dangerous chimney
fires.
A few minutes spent understanding firewood will be time well
spent, so please read on for general background information, as
well as how to buy wood and store wood.
Seasoned Wood
All firewood contains water. Freshly cut wood can be up to 45%
water!, while well seasoned firewood generally has a 20-25%
moisture content. Well seasoned firewood is easier to start,
produces more heat, and burns cleaner. The important thing to
remember is that the water must be gone before the wood will
burn. If your wood is cut 6 months to a year in advance and
properly stored, the sun and wind will do the job for free. If
you try to burn green wood, the heat produced by combustion must
dry the wood before it will burn, using up a large percentage of
the available energy in the process. This results in less heat
delivered to your home, and literally gallons of acidic water in
the form of creosote deposited in your chimney.
Wood is composed of bundles of microscopic tubes that were
used to transport water from the roots of the tree to the
leaves. These tubes will stay full of water for years even after
a tree is dead. This is why it is so important to have your
firewood cut to length for 6 months or more before you burn it,
it gives this water a chance to evaporate since the tube ends
are finally open and the water only has to migrate a foot or two
to escape. Splitting the wood helps too by exposing more surface
area to the sun and wind, but cutting the wood to shorter
lengths is of primary importance.
There are a few things you can look for to see if the wood
you intend to purchase is seasoned or not. Well seasoned
firewood generally has darkened ends with cracks or splits
visible, it is relatively lightweight, and makes a clear
"clunk" when two pieces are beat together. Green wood
on the other hand is very heavy, the ends look fresher, and it
tends to make a dull "thud" when struck. These clues
can fool you however, and by far the best way to be sure you
have good wood when you need it is to buy your wood the spring
before you intend to burn it and store it properly.
Storing Firewood
Even well seasoned firewood can be ruined by bad storage.
Exposed to constant rain or covered in snow, wood will reabsorb
large amounts of water, making it unfit to burn and causing it
to rot before it can be used. Wood should be stored off the
ground if possible and protected from excess moisture when
weather threatens.
The ideal situation is a wood shed, where there is a roof but
open or loose sides for plenty of air circulation to promote
drying. Next best would be to keep the wood pile in a sunny
location and cover it on rainy or snowy days, being sure to
remove the covering during fair weather to allow air movement
and to avoid trapping ground moisture under the covering. Also
don't forget that your woodpile also looks like heaven to
termites, so it's best to only keep a week or so worth of wood
near the house in easy reach. With proper storage you can turn
even the greenest wood into great firewood in 6 months or a
year, and it can be expected to last 3 or 4 years if necessary.
Buying Firewood
Firewood is generally sold by volume, the most common measure
being the cord. Other terms often employed are face cord, rick,
or often just a truckload. A standard cord of firewood is 128
cubic feet of wood, generally measured as a pile 8 feet long by
4 feet tall by 4 feet deep. A face cord is also 8 feet long by 4
feet tall, but it is only as deep as the wood is cut, so a face
cord of 16" wood actually is only 1/3 of a cord, 24"
wood yields 1/2 of a cord, and so on.
Webster defines a rick simply as a pile, and truck sizes
obviously vary tremendously, so it is very important that you
get all of this straight with the seller before agreeing on a
price; there is much room for misunderstanding. It is best to
have your wood storage area set up in standard 4 or 8 foot
increments, pay the wood seller the extra few dollars often
charged to stack the wood, and warn him before he arrives that
you will cheerfully pay only when the wood actually measures up
to an agreed upon amount.
Another thought concerning getting what you pay for is that
although firewood is usually sold by volume, heat production is
dependent on weight. Pound for pound, all wood has approximately
the same BTU content, but a cord of seasoned hardwood weighs
about twice as much as the same volume of softwood, and
consequently contains almost twice as much potential heat. If
the wood you are buying is not all hardwood, consider offering a
little less in payment
