The key to successful wood burning Whether you burn wood in a fireplace, stove or furnace, good quality firewood is the key to convenience, efficiency and safety. Wet wood and pieces that are not the right size and shape for your wood burner can be frustrating, burn inefficiently and deposit creosote that can fuel a dangerous chimney fire. Good planning, seasoning and storage of the firewood supply are essential to successful wood burning.
Measuring firewood quantity and comparing prices
The first challenge in buying firewood is to measure quantity so you can compare prices. The cord is the standard unit of measurement for firewood. A cord measures 4 x 4 x 8 ft. But nobody burns four foot long pieces, so some dealers sell fractions of cords, often called “face cords”, which are piles of wood 4 ft high and 8 ft long and as wide as the length of the individual pieces, usually between 12 in and 20in. The price of firewood sold in fractions of cords can be compared by calculating the volume of wood sold as a unit and comparing its cost per full cord. T
Tips on buying good firewood
What are the best tree species for firewood?
All wood is chemically similar, regardless of species. It is the density that influences its behaviour in the fire and its value as firewood. Dense hardwoods like maple and oak have a higher energy content per cord and so release more heat per firebox load. They also produce long-lasting fires and coal beds. Softer woods like pine, spruce and poplar are less dense, burn faster and do not produce a long-lasting coal bed when burned.
Traditionally, hardwoods were the preferred firewood, but softer woods make excellent fuel for spring and fall use. The newer advanced technology wood stoves, fireplaces and furnaces can function well with a wider variety of wood species because of their better control of the combustion process than older conventional stoves.
The length of the pieces must be suitable for your stove, furnace or fireplace. Shorter pieces are easier to handle and preferable to pieces that are too long for the appliance. Pieces that are even slightly too long can make fire stoking difficult or impossible. For stoves and furnaces, pieces should be at least 3 in shorter than the fire box size. Even if a stove firebox is big enough to take firewood as long as 20 in, shorter pieces are usually more desirable for ease of handling and fire maintenance. Good quality firewood is a consistent length. Lengths varying more than 2 in are a sign of poor quality and may cause problems in loading the appliance. For convenient handling and stoking in most wood stoves, firewood is best cut into pieces 14 to 16 in long. All pieces should be about the same length
Most commercial firewood is not split small enough for effective fire building and maintenance. Big firewood pieces tend to smoulder longer when placed in the fire, whereas smaller pieces ignite quickly. Small pieces are better for small fires in mild weather. Even in cold weather each load should be made up of a few small pieces that will ignite quickly and some larger pieces that will burn steadily for several hours. Ideally, the wood should be split to a variety of sizes ranging from 3 in to 6 in measured across the largest cross section. Expect to pay more for wood that is split smaller and into a variety of sizes. Small firewood pieces are often better than large pieces for convenient stoking. A range of piece sizes is best.
Tips for stacking and storing firewood
How to tell if wood is dry enough
There are a few ways to tell if wood is dry enough to burn efficiently. Use as many indicators as possible to judge the dryness of the firewood your are considering.
In the fall, move the wood to winter storage
When the firewood has dried in the sun and summer breezes, move it to winter storage. The area should be dry and fully sheltered from rain and snow. Ideally, this area is close to, but not inside the house. Large amounts of wood should not be stored inside houses because of the risk of mold growth, which can contaminate the indoor air with spores. However, a small amount of wood stored inside can give it time to warm to room temperature before burning. Look for firewood produced using sustainable harvesting methods Try to buy your wood from someone who uses good forest management practices. Environmentally sound woodlot management involves thinning out dying and damaged trees and less desirable species. To support sustainable forestry practices, use wood from a blend of species. Burn the softer woods, such as pine, poplar and aspen, in the spring and fall. These are the ways you can help to ensure that wood is a sustainable energy source for home heating.
Why is there no standard price for firewood?
Here are some of the factors that can affect the price of firewood:
For all these reasons, firewood can range in price from less than $150 for the equivalent of a full cord to more than $300. Paying a little extra to get good quality seasoned firewood that is the right length and split properly is a good investment because of increased convenience and efficient burning.
