It's Time To Expand Your Woodburning Stove Options How to Properly Operate a Woodburning Stove Wood stoves are an excellent way to heat your home. They're also inexpensive. But the smoke they emit can be harmful to your health. It is important to know how these appliances operate and how to use them safely. Modern stoves employ secondary or catalytic combustion to control emissions. But older stoves and open fires produce 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 thought of as a combustion chamber with walls and a lid. The majority of fireplaces have an already-built metal firebox or a masonry firebox. The type of firebox you choose will depend on your personal preferences and the type of fireplace you own. Most wood-burning fireplaces make use of a constant flow of air to create the fire and burn fuel. Fresh air is drawn into the stove via dampers which can be adjusted inside its 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 through the chimney and safely away from your home. Modern stoves with catalytic second combustion use a special catalyst that allows the unburned gasses to create additional heat. This results in more clean and less polluting smoke than traditional wood stoves with no secondary combustion. Modern non-catalytic stoves are also available, but they're typically less efficient than stoves with catalytic secondary combustion. Some fireplaces with wood burning have backboilers that can be used for space heating as well as water heating. These stoves are known as "hybrids" or "combination". They have been in use since the early 20th century. Wood burning stoves can only be made use of well-seasoned wood. Freshly cut wood (green) has an excessive amount of water. This could lead to low flue temperatures, as well as an excessive accumulation of creosote in the chimney. This can cause chimney fires that cause damage to the stove, and they could be harmful to your family's health. If you're in search of a professional who can inspect your wood-burning stove, or make firebox repairs, ensure that the chimney technician you choose has CSIA certification and also has customer testimonials on their site. Find out their rates and the type of work they do. The pipe for ventilation Wood stoves require ventilation to eliminate fumes from combustion and help keep the home warm and healthy. Venting helps eliminate carbon monoxide, nitrogen dioxide and excess moisture from the process of combustion. It also reduces the amount of air pollution and heat loss outside. Wood, gas and pellet stoves have different venting requirements. It is essential to maintain the stove's venting systems on an every year to ensure security and efficiency. The ventilation system consists of the firebox, the vent pipe and the chimney. The chimney and ventilation pipe are used together to create a draft that draws smoke from the stove out through the fireplace. Draft is generated through the difference in temperature and density between hot wood smoke and cold air outside. The higher the temperature, more smoke can rise through the ventilation pipe and chimney. Most modern wood stoves are certified by the EPA as low-emission units. This means they emit far fewer pollutants than older models, which contribute to global warming and other environmental issues. Most newer stoves also come with pollution controls built-in to reduce the amount of carbon dioxide they emit, while also ensuring that the emissions are disposed of in an efficient manner. Older stoves with open flues produce a lot more carbon dioxide, which is an extremely poisonous gas and should not be allowed to escape into the home. Carbon monoxide is produced when the chimney is dirty or has inadequate ventilation. Installing carbon monoxide alarms in your house is therefore important. Before installing a brand new or used wood stove determine the distance between the point where the stove is on the floor to the chimney opening on the ceiling or wall. Multiply modern wood burner by two to find the length of stovepipe you need. You can choose to use single-wall or double-wall stovepipes and be aware of the proper clearances from combustibles. When the stove first starts to burn and the flame is first lit, adjust the vent until a stable flame has been established and the combustion is stable. It is recommended to avoid using wood based logs in the stove since they may contain volatile chemicals that can cause the air vents to fail. The chimney The chimney is a complex system that requires careful care. The chimney is composed of many important components that are all crucial for the safety and efficiency of your stove. The ventilation pipe, the firebox and chimney work together to exhaust the gases from combustion produced by your woodburning stove to the outside. This is crucial to reduce carbon dioxide levels as well as prevent harmful emissions. To achieve this the chimney and flue should be hot enough to allow the gases to exit the fireplace without cooling. This is accomplished by using a woodburning stove that has high heat output and by frequently adding new logs to the fire. Modern wood-burning stoves have a higher chimney than older systems to increase the effect of drafting. However, this may be a disadvantage when the height of your chimney exceeds the maximum allowed for your particular location. In this situation the chimney may compete with the stack of your house for airflow, causing the gases to cool before leaving. This can cause a restriction in the flow of gas, and a buildup on creosote. The most common error homeowners make is to open the fireplace door and close it too often. This can negatively affect the combustion. It is important to keep the fireplace door as shut as you can and only open it to add ash or firewood. The door shouldn't be open for long. This allows the hot air from the stove to escape, making the logs cooler and more difficult to light. Other kinds of combustibles may cause higher emissions or even an explosion in a chimney. Woodburning stoves are designed and optimised 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 development and air flow. The flue should be at least 25 percent larger than the pipe connecting the stove and chimney to allow for sufficient smoke flow. A wood stove should be placed on a non-combustible hearth with a clear area in front of fireplace opening. Modern stoves feature an element called catalytic combustor, which can cut down on the amount of harmful by-products which are released into the chimney. This feature can help increase the efficiency of wood stoves by burning a fire that produces more heat and releasing less pollution. Utilizing other kinds of combustibles other than firewood however, could cause issues with lower efficiency and higher levels of emissions. It is crucial to use seasoned or dry wood when burning wood in your stove or fireplace. If your wood isn't seasoned or dry it will release high levels of water vapor and creosote into the chimney. This could result in low flue temperatures, and even a chimney fire. A professional can also help you avoid a fire in your chimney by regularly inspecting and cleaning the flue system. This includes the stovepipe, the chimney, and the chimney itself. A dirty flue and stove could result in a poor chimney draft that could release carbon monoxide into your home. This could be harmful for your family members and you should never let it happen. A good rule of thumb is to ensure that your stove and chimney are cleaned by a professional once a year. This will also help to keep your chimney and stove functioning efficiently.
