If you have one, it is essential to keep it maintained regularly to prevent dangerous build-ups of creosote. A damper is an important element in maintaining a high quality combustion. Hardwoods like oak and ash produce less creosote. Energy Efficiency Wood fireplaces can be an attractive feature, creating warm and inviting ambience. However, they are not efficient in energy use and can result in harmful air pollution if they aren't properly maintained. The condition and the quality of your chimney, firebox system, and installation may have a significant impact on the overall efficiency. The main fuel source for a traditional wood burning stove is firewood, which is typically purchased in a face cord or full cord (measured at 4'x8'x8'). Before using firewood, it must be "seasoned", to reduce the amount of water and increase its energy density. If the wood is too wet it will not burn as efficiently and could cause lots of creosote. Seasoning wood generally takes from months to a year or more, based on the weather and the climate. Wood burning fireplaces demand a significant investment of time and money to keep them properly. In addition, to purchasing large quantities of firewood, homeowners must regularly check and clean their fireplace. This is to ensure that the chimney is clear of obstructions, that it is operating correctly, and that there is no combustible material close to the fireplace. Regular cleaning and inspections will reduce the risk of chimney fires and room fires. Smoke from a wood-burning stove is a source of fine particle pollution which can damage the lungs and lead to serious health problems including lung disease, cardiovascular disease and heart attacks. It also releases carbon monoxide and other toxic air pollutants including volatile organic compounds such as nitrogen oxides,
