How to Properly Operate a Woodburning Stove Wood stoves are a fantastic option to heat your home. They're also cheap. But the smoke they emit can also be harmful to health. It's important to understand how these appliances work and how to use them correctly. Modern stoves use secondary or catalytic combustion to reduce emissions. However, older stoves and open fires produce large amounts 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 described as a combustion chamber that has walls and an enclosure. Most fireplaces have either an already-built metal or the masonry fireboxes. The type of box you choose will depend on your personal preferences and the type of fireplace you have. Most wood-burning fireplaces use a constant air flow to create the fire and burn fuel. Fresh air is drawn in through the adjustable dampers within the doors of the stove. This allows the fuels to burn properly, and reduces toxic gases produced by incomplete or unburnt combustion. The exhaust gases are then transported through the chimney and safely out of your home. Modern stoves that have catalytic secondary combustion make use of a specific catalyst to reburn the unburnt gasses to create additional heat. This results in a much cleaner and less polluting emission than traditional wood stoves that have no secondary combustion. Modern non-catalytic wood stoves are also available, but these are typically less efficient than those with catalytic second combustion. Certain fireplaces that burn wood have backboilers, which can be used for space heating and water heating. These stoves are referred to as hybrids or combination. They are in use since the beginning of the 20th century. Wood burning stoves must be used with seasoned wood. Freshly cut wood burning stoves uk (green) has high levels of water. This can lead to low flue temperatures and excessive creosote accumulation within the chimney. This could lead to chimney fires that destroy the stove, and they can be hazardous to your family's health. If you're looking for an expert to examine your wood-burning stove, or make any firebox repairs ensure that the chimney specialist you choose is CSIA certified and offers testimonials from customers on their website. It's also important to ask about their rates and what is the type of work they can do. The pipe that allows for ventilation Ventilation is essential for wood stoves to help remove smoke and keep the home safe and warm. Ventilation is essential to remove carbon monoxide and nitrogen dioxide from the process of combustion. It also helps reduce the amount of air pollution and heat loss to the outdoor. Gas, wood and pellet stoves all have different requirements for venting. It is important to maintain the stove's venting systems on an every year to ensure security and efficiency. The ventilation system consists of the firebox and the vent pipe. The chimney and the pipe work together to create a draft that draws smoke from the stove out through the fireplace. Draft is created by the differences in temperature and density between hot wood smoke and cold outside air. The greater the temperature of the smoke, the better it can rise through the chimney and vent pipe. Modern wood stoves have been certified as low-emission models by the EPA. They produce far less pollutants than older models, which contribute to global heating and other environmental issues. Most modern stoves have built-in pollution control systems that limit the amount of emissions while making sure that they burn efficiently. Older stoves with open flues produce much more carbon dioxide, an extremely poisonous gas and should not be allowed to escape into your home. Carbon monoxide is produced if your chimney is dirty or there is inadequate ventilation. Installing carbon monoxide alarms inside your house is therefore important. Measure the distance between the opening of the chimney in the ceiling or wall and the location where the wood stove is located on the floor. Multiplying this number by 2 will provide you with the minimum length of stovepipe that you will require. Single-wall or double-wall stovepipes, and you must account for proper clearances from combustibles for either type. The stove's air vent should be adjusted whenever it is first lit up and maintained until a stable flame is created in the stove and its combustion process has stabilized. It is advised to avoid using wood based logs in the stove as they may contain volatile chemicals which can cause the air vents to malfunction. The chimney The chimney may not be something that homeowners give a lot of thought to, but it's an intricate system that requires careful attention. From top to bottom, the chimney is made up of a number of important components that are crucial to ensure that your stove works safely and efficiently. The wood burning stove's combustion gases are vented to the outside by the firebox, the vent pipe, and the chimney. This is crucial to reduce carbon dioxide levels as well as prevent harmful emissions. To achieve this, the chimney and flue have to be sufficiently hot to allow the gasses out of the fireplace without them cooling. This is achieved by using a woodburning stove with a high heat output and by adding regularly new logs to the fire. The majority of modern woodburning stoves are designed to operate with a chimney which is higher than older systems in order to achieve a better draft effect. This could be a problem if your chimney height exceeds the maximum allowed for your area. If this occurs, the chimney may compete with the house stack for draft, causing the gases to cool prior to exiting. This can cause a restriction in the flow of gas and the formation of creosote. One of the most common mistakes homeowners make is to open and shut the fireplace door too frequently which can adversely affect the combustion. It's important to leave the door of your fireplace closed as much as possible and only open it when you're required to add more ash or firewood. Keeping the door open too long permits the hot air to escape from the stove, causing the logs to become cooler and more difficult to light, and also releases unburned volatile compounds into the room. Other types of combustibles could produce higher emissions or a chimney fire. Woodburning stoves were developed and optimized for burning wood for fire. They are not suitable for other combustibles. The flu A woodburning stove needs a correctly sized flue to allow for adequate draft and air flow. The flue must be at least 25 percent larger than the pipe connecting the chimney and the stove to allow for adequate smoke flow. A wood stove should be set on a non-combustible hearth that has a clear space in front of fireplace opening. Modern stoves come with a feature called catalytic combustor, which can reduce the amount of harmful byproducts that are released into the chimney. This feature can improve the efficiency of wood stoves by burning a flame which produces more heat while emitting less pollutants. However, using other kinds of combustibles, such as coal, can cause issues, including lower efficiency and more emissions. When burning wood in a stove or fireplace it is essential to burn seasoned or dried wood. If your wood isn't dry or seasoned, it will emit high levels of creosote and water vapour into the chimney. This could result in low flue temperatures and even a fire in the chimney. Another way to avoid a fire in your chimney is to have a professional examine and clean your flue system regularly. This includes the stovepipe, chimney and the chimney itself. A dirty stove and flue system can lead to an unclean chimney draft that could result in carbon monoxide being released into your home. This could be hazardous for your family members and should never be allowed to happen. A good rule of thumb is to hire a professional chimney sweep clean your chimney and stove once per year. This will keep your chimney and stove in good working order.
