How to Properly Operate a Woodburning Stove Wood stoves are an affordable and cozy method to heat your home. Smoke from wood stoves can be hazardous to your health. It is crucial to know how these appliances operate and to use them correctly. Modern stoves employ secondary or catalytic combustion to control emissions. However, 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 most simple way to think about the firebox is that it's an open-air combustion chamber that has walls and an entrance. The majority of fireplaces have a prefabricated metal firebox or masonry firebox. The type of firebox you pick will depend on your preferences as well as the type of fireplace you own. Most wood-burning fireplaces utilize a continuous flow of air to create the fire and burn fuel. Fresh air is drawn through the adjustable dampers in the stove's doors. This lets the fuel burn efficiently and helps reduce harmful gases produced by incomplete or unburnt combustion. The exhaust gases are then taken up by the chimney and safely out of your home. Modern stoves with catalytic secondary combustion employ a special catalyst that reburns the unburned gasses to generate additional heat. This results in a more clean and less polluting exhaust than traditional wood stoves that have no secondary combustion. Modern non-catalytic stoves are also available, but they're usually less efficient than stoves that have secondary combustion catalytically. Some wood-burning fireplaces come with backboilers that can be used for space heating and water heating. These are referred to as combination or hybrid stoves and have been around since the early 20th century. Wood burning stoves should only be used with seasoned wood. Freshly cut wood (green) has high levels of water. This can result in low flue temperatures, as well as an excessive accumulation of creosote in the chimney. This can cause chimney fires that can harm your stove or be harmful to the health of your family. If you're looking for an expert to examine your wood-burning stove or perform any firebox repairs ensure that the chimney specialist you choose is CSIA certified and offers reviews from their customers on their website. Ask about their pricing and the kind of work they perform. The ventilation pipe Wood stoves require ventilation to eliminate the smoke from the combustion process and keep the home warm and healthy. wood burning stoves for sale carries away 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 all have different venting requirements. 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 as well as the ventilation pipe. The chimney and ventilation pipe are used together to create a draft that draws smoke from the stove out through the fireplace. The differences in densities and temperature between the hot wood smoke and the cold outside air creates draft. The more hot the smoke, the more it can rise through the chimney and ventilation pipe. Modern wood stoves are certified as low-emission units by the EPA. They emit less pollution than older models that contribute to global heating and other environmental problems. The majority of modern stoves have built-in pollution controls to limit the amount they release while ensuring the emissions are burned in an efficient manner. Older stoves that have open flues produce more carbon dioxide. This is a toxic, toxic gas and it should not be released into your home. This can happen if your chimney is not clean or there is inadequate ventilation, which is why it is important to install carbon monoxide detectors in your home. Before installing a brand new or used wood stove, take note of the distance from the place where the stove is placed on the floor to the chimney opening in the ceiling or wall. Multiplying this number by 2 will give you the shortest length of stovepipe you need. You can choose a single-wall or double-wall stovepipes however, you must ensure adequate clearance from combustibles. When the stove first starts to burn, adjust the air vent until a stable flame has been established and combustion process is stable. It is also a good idea to stay clear of using wood briquettes in the stove, as they aren't logs and can contain volatile chemicals that can cause the air vent to malfunction and lead to a risky situation. The chimney The chimney is a complex system which requires attention and care. From top to bottom, the chimney is comprised of several important components each of which is crucial to ensuring that your stove operates effectively and safely. The firebox, ventilation pipe and chimney work together to vent the combustion gases produced by your woodburning fireplace to the outside. This is essential in preventing harmful emissions and reducing carbon dioxide levels within your home. To accomplish this the chimney and flue have to be sufficiently hot to carry the gasses out of the fireplace without cooling. This can be achieved by using a wood-burning stove which has a high heat output and by adding fresh logs frequently to the fire. Modern wood-burning stoves have a higher chimney than older models to increase the effect of drafting. However, this can be a disadvantage if the height of your chimney is higher than the maximum permitted for your particular location. In this situation the chimney could be competing with the house's stack for airflow, causing gases to cool down before leaving. This can cause a restriction in the flow of gas, and a buildup on creosote. One of the most frequent mistakes homeowners make is to open and close the fireplace door too frequently which could negatively impact the combustion. It is essential to keep the fireplace door as closed as possible, and only open it when you need to add ash or firewood. The door should not be opened for too long. This lets hot air from the stove to escape, making the wood cooler and more difficult to light. Other types of combustibles could produce higher emissions or a chimney fire. Woodburning stoves were developed and optimized for burning firewood. They are not suitable for other combustibles. The flue To ensure proper air flow for a woodburning stove, it requires an exhaust pipe that is the right size. The flue should be at a minimum 25 percent larger than the pipe connecting the chimney and stove to allow sufficient smoke flow. In addition the wood stove should be placed on a hearth that is made of a non-combustible material and is clear and unobstructed space in the front of the opening for the fireplace. Modern stoves have a catalytic combustion system that reduces the amount of harmful byproducts released into the chimney. This feature can improve the efficiency of wood stoves by burning a flame which produces more heat while releasing less pollution. However, using different types of combustibles, such as coal, could cause issues, including lower efficiency and higher emissions. It is important to use seasoned or dry wood when burning wood in your fireplace or stove. If your wood isn't well-seasoned or dried, it will release a large amount of water vapor into your chimney. This can result in low flue temperatures and possibly a chimney fire. A professional can also assist you in avoiding a fire in your chimney by regularly checking and cleaning the flue system. This includes the stovepipe, the chimney, and the chimney itself. A soiled stove or flue system can cause a poor draft in your chimney, which could cause carbon monoxide build-up in your home. This could be hazardous for your family and should never be allowed to occur. A good rule of thumb is to hire an experienced chimney sweep clean your chimney and stove each year. This will also help to keep your chimney and stove working efficiently.
