How to Properly Operate a Woodburning Stove Wood stoves are an excellent option to heat your home. They're also affordable. Smoke from wood stoves can be dangerous to your health. It is essential to know how these appliances work and how they operate. Many modern stoves rely on a catalytic or secondary combustion to control their emissions. Older stoves and open flames release high levels of particulates. The firebox The firebox is the heart of any fireplace system. It's where you create a fire to heat your home and provide ambiance. It's a simple concept, but there are many important details that must be accounted for to keep your wood burning stove safe and efficient. The firebox is considered an open-air combustion chamber with walls and a lid. Most fireplaces come with a prefabricated metal firebox or masonry firebox. The type of firebox you pick will depend on your personal preferences and the type of fireplace that you have. Most wood-burning stoves use a constant flow of air to generate the fire and burn the fuel. Fresh air is drawn into the stove through adjustable dampers that are located in the stove's doors. This lets the fuel burn efficiently and helps reduce toxic gases that are produced by incomplete or unburnt combustion. The exhaust gases will then be drawn up the chimney and safely away from your home. Modern stoves with catalytic second combustion employ a special catalyst that reburns the unburned gasses to generate additional heat. This produces a more clean and less polluting exhaust than traditional wood stoves that have no secondary combustion. Modern non-catalytic stoves are available, but they're generally less efficient than stoves that have secondary combustion that is catalytic. Certain wood-burning stoves come with backboilers that are used to heat water in addition to space heating. These stoves are called hybrids or combination. They are in use since the beginning of the 20th century. Wood burning stoves should only be lit with well-seasoned wood. Freshly cut wood (green) has high levels of water. This can lead to low flue temperatures, and an excessive accumulation of creosote in the chimney. This can lead to chimney fires, which can damage your stove and even be hazardous to the health of your family. If you're in search of an expert to examine your wood burning stove or perform any firebox repairs, make sure the chimney expert you hire is CSIA certified and offers testimonials from customers on their website. You can inquire about their prices, and what type of work they can perform. The pipe for ventilation Ventilation is essential for wood stoves in order to eliminate fumes and keep the house healthy and warm. Ventilation helps remove carbon monoxide, nitrogen dioxide and excess moisture from the process of combustion. It also helps to reduce air pollution and loss of heat to the outdoors. Wood, gas and pellet stoves all have different venting requirements. Maintaining the stove's ventilation system annually is critical to ensure safety and efficiency. The ventilation system consists of the firebox as well as the ventilation pipe. The chimney and the vent pipe work together to create draft, which draws smoke from the stove through the fireplace and into the outside air. The differences in temperature and densities between the hot wood smoke and cold outside air creates draft. The higher the temperature of the smoke, the more it can rise up the chimney and ventilation pipe. The majority of modern wood stoves are EPA-certified as low-emission units. They produce less pollution than older models that contribute to global heating and other environmental concerns. Most modern stoves have built-in pollution control systems to limit the amount of emissions, while making sure that they burn efficiently. Older stoves with open flues produce more carbon dioxide. It is a poisonous, toxic gas and it should not be released into your home. Carbon monoxide can be a source if your chimney is dirty or has inadequate ventilation. Installing carbon monoxide alarms inside your home is therefore essential. Find the distance between the opening of the chimney in the wall or ceiling and the spot where the wood stove is located on the floor. Multiply this number by two to calculate the length of stovepipe that you require. You can use a single-wall or a double-wall stovepipe, but you must ensure the adequate clearance from combustibles. When the stove is lit for the first time, adjust the air vent until a proper flame has been established and combustion is stable. It is also a good idea to avoid using wood briquettes in the stove, since they aren't logs and can contain volatile chemicals that can cause the air vent to malfunction and create a dangerous situation. The chimney The chimney is a complex system which requires attention and care. From top to bottom the chimney is made up of several important components each of which is essential to ensure that your stove operates effectively and safely. The wood-burning stove's combustion gases are vented to the outside through the firebox, the vent pipe, and the chimney. This is essential in preventing harmful emissions and reducing carbon dioxide levels in your home. To accomplish wood burning stove near me and flue must be sufficiently hot to allow the gases to exit the fireplace without cooling. This can be achieved by using a wood-burning stove which has a high output of heat and by adding new logs on a regular basis to the fire. Modern woodburning stoves are designed to operate with a chimney that's taller than older models to achieve a better draft effect. However, this could have disadvantages when the height of your chimney is higher than the maximum permitted for your location. In this scenario the chimney could be competing with the house's stack for airflow, causing gases to cool before leaving. This could impede the gas flow and cause creosote buildup that could be a fire hazard. One of the most frequent errors that homeowners make is to open and close the fireplace door too frequently which can adversely affect the combustion. It's important to leave the fireplace door closed whenever you can and only open it when you are required to add more firewood or ash. The door shouldn't be left open for too long. This allows hot air from the stove to escape, making the wood cooler and harder to light. Another mistake that many make is to use different kinds of combustibles inside their woodburning stoves, which can result in higher emissions, or even a chimney fire. Woodburning stoves were developed and optimized for burning wood for fire. They are not suitable for other combustion products. The flu To ensure that the airflow is proper, a woodburning stove needs an exhaust pipe that is the proper size. The flue should be at a minimum 25% larger than the stove pipe that connects the chimney and stove to allow sufficient smoke flow. In addition the stove must be set on a hearth constructed of a non-combustible substance and has a clear, unobstructed space in front of the fireplace opening. Modern stoves come with a feature called catalytic combustor which can cut down on the amount of harmful by-products that are released into the chimney. This feature can help increase the efficiency of wood stoves by burning a flame which generates more heat while releasing less pollution. Making use of other types of combustibles other than firewood however, could cause issues, such as lower efficiency and more emission levels. When burning wood in a stove or fireplace it is essential to use dried or seasoned wood. If the wood isn't properly seasoned or dried, it could emit a lot of water vapor into your chimney. This can result in low flue temperatures, and even a chimney fire. Another way to prevent a chimney fire is to have a professional examine and clean your flue system on a regular basis. This includes the chimney, stovepipe and the chimney itself to ensure that everything is in good shape. A unclean stove and flue system could result in a poor chimney draft that could release carbon monoxide into your home. This can be dangerous to your family members and you should never let it occur. A good rule of thumb is to hire an experienced chimney sweep sweep your stove and chimney once per year. This will help keep the stove and chimney working efficiently.
