Nothing is worse than building a roaring fire, only to experience a smoky room. Unfortunately, many people deal with smoke problems associated with a fireplace but with the right information, you can change that. Remember, if you smell smoke, chances are your fireplace or wood-burning stove is not working properly. The problem is that while a gentle waft of smoke is one thing, too much smoke is air pollution, which is harmful and could even be deadly.
However, if your fireplace or stove are designed, installed, and working as they should, then you would enjoy the heat produced and ambience but without the smoke. In addition to having your fireplace or wood-burning stove in proper working condition, you also want to use the right type of wood, as well as seasoned wood. If wood is too green, it contains high water content, which causes smoke.
Typically, the problem with smoke is due to poor system design with your fireplace or stove. What happens is that low draft and flue temperatures are serious problems. If your fireplace has a long, single walled flue pipe, then what happens is excessive heat is produced prior to gas reaching the chimney. In addition, a 90-degree flue pipe would cause a problem with slow or now gas flow. Finally, if your chimney goes up the outside wall, chances are a weak draft is created. In this case, you would need a new solution so gasses can escape, forcing smoke outside.
Another common problem with some is that the house has negative pressure. For instance, most building codes result in an airtight house, which you would think is a good thing. Yes, the new home is easier to heat due to less air leakage but for high-volume exhausts, you would face challenges. Because of this, the house develops negative pressure when compared to air on the outside. Unfortunately, this then works in contrast with chimney draft. Now, if the problem is severe, smoke is drawn back down the chimney, where it flows inside the house.
Another reason for smoke in the house is from a smoldering fire. In this case, if wood does not have enough air, it smolders. With this, exhaust temperature decreases too low, which means an appropriate draft is not produced. As it would happen, opening the glass door while a fire were smoldering would also cause smoke to filter into the home. Now, remember that even closed doors during a smoldering fire may not be enough to stop the flow of smoke.
Finally, some smoke inside the house can be reduced or even eliminated by using a duct. Keep in mind that some people do not believe this works, while some do. The reason is at the controversy is that smoke can still happen at the same level of room depressurization, even if an outdoor duct were not installed. Therefore, do your homework prior to going this route, as a means of eliminating smoke spillage into the home.
