Stay Warm This Winter with the Perfect Firewood

Thursday, December 15, 2011 | 08:31am
NASHVILLE – The Tennessee Department of Agriculture is offering advice to consumers purchasing firewood this winter. When purchasing firewood, consumers need to take into consideration a variety of factors including the type of wood, its origin and the quantity.
 
“Firewood can be purchased almost anywhere and in many varieties,” said Steve Scott, State Forester. “Consumers should educate themselves to make sure they get the best product for their money.”
 
The first factor to consider while purchasing firewood is the type of wood because different woods burn differently and produce varying amounts of heat. For example, oak burns slower and produces less smoke while pine burns faster and produces more soot and smoke. Educate yourself about the type of wood that will best serve your needs.
 
After deciding on the type of wood, be sure to ask retailers about the seasoning of the wood. Seasoning is the process of drying wood. Firewood typically takes nine months to become seasoned. Burning wood that has not been dried out properly or seasoned will produce less heat, burn poorly and create unnecessary soot and smoke.
 
Another factor to take into consideration when purchasing wood is the origin of the wood. This is important because buying wood from other states may transport invasive exotic insects into Tennessee. Consumers can help avoid potential problems by purchasing firewood locally harvested near where they plan to burn it.
 
“The Emerald Ash Borer and Thousand Cankers Disease are two examples of invasives that have devastated many native hardwood trees in the U.S. as a result of the transportation of infested wood products,” said Scott. “We continue to survey for both EAB and TCD since their discovery in Tennessee last year. Citizens can help slow the spread by burning firewood near where they buy it and by obeying county firewood quarantines.”
 
The last factor to consider when buying firewood is the quantity. Firewood has its own unit of measurement called a cord. Firewood must be sold by the cord or fractions of a cord starting at 1/8 of a cord. A cord of wood by law must equal 128 cubic feet. Be wary of terms such as face cord, rack, rick, tier, pile or truck-load, as these terms are not standardized in the sale of firewood. Some firewood dealers also try to sell firewood by the truckload. A typical pick-up truck cannot hold a cord of firewood. Rest assured, when purchasing firewood at brand retailers, there are established labeling protocols for firewood. 
 
If consumers follow these tips, they can feel confident that they purchased a local, worthy product that will keep them warm throughout the winter months.
