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 harmful 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 reduce their 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 most straightforward way to think of the firebox is to think of it as an enclosed combustion chamber that has walls and doors. Most fireplaces have an already-built metal or the masonry firebox. The type of firebox you choose will depend on your personal preferences and the type of fireplace you own. Most wood-burning stoves use an air flow that is constant to produce the fire and burn the fuel. Fresh air is pumped into the stove via dampers that can be adjusted inside the doors. This allows the fuels to be burned correctly, and also reduces the toxic gases that are produced by burning that is not complete or properly burned. The exhaust gases are drawn up through the chimney and safely out of your home. Modern stoves with catalytic secondary combustion employ a special catalyst that allows the unburned gasses to generate additional heat. This results in a cleaner and less polluting exhaust than traditional wood stoves that have no secondary combustion. Modern wood stoves that are not catalytic are available however they are generally less efficient than those with secondary combustion that is catalytic. Certain fireplaces that burn wood have backboilers that 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 should be lit with seasoned wood. Freshly cut wood (green) has an excessive amount of water. This could lead to low flue temperatures and an excessive accumulation of creosote in the chimney. This can lead to chimney fires that destroy the stove and could be harmful to your family's health. If you're in search of an expert to look over your wood-burning stove or make any firebox repairs ensure that the chimney professional you choose is CSIA certified and has reviews from their customers on their website. It's also important to inquire about their pricing and what is the type of work they can do. The pipe that allows for ventilation Wood stoves require ventilation in order to remove emissions from the combustion process and keep your home warm and healthy. Ventilation is necessary to remove carbon monoxide and nitrogen dioxide from the combustion process. It also helps reduce the amount of air pollution and heat loss outside. Wood, gas and pellet stoves all have different requirements for venting. It is crucial to keep the stove's venting system on every year to ensure safety and efficiency. The ventilation system consists of the firebox, the ventilation pipe and chimney. The ventilation pipe and chimney work together to create draft, bringing smoke from the stove through the fireplace and into the outside air. The differences in temperature and densities of the hot wood smoke and cold outside air creates draft. The more hot the smoke, the more it can rise through the chimney and through the ventilation pipe. Modern wood stoves are EPA-certified low-emission units. This means they emit significantly less pollution than older models, which contribute to global warming and other environmental issues. The majority of modern stoves come with pollution control systems to limit the amount of carbon dioxide released while ensuring that they are burned efficiently. small wood burner that have open flues create lots of carbon dioxide, which is poisonous gas that should not be allowed to escape into the home. This can happen if your chimney is not properly maintained or there is insufficient ventilation. It is crucial to install carbon monoxide detectors into your home. Before installing a brand new or used wood stove take note of the distance from the point where the stove is on the floor to the chimney opening on the ceiling or wall. Multiplying this number by 2 will provide you with the minimum length of stovepipe you require. You can use either single-wall or a double-wall stovepipe, but you must ensure adequate clearance from burning combustibles. The stove's air vent should be adjusted when it first starts to light up until a proper flame is created within the stove and its combustion process has been stabilized. It is advised to stay clear of using wood logs in the stove since they may contain volatile chemicals that can cause the air vents to fail. The chimney The chimney may not seem like something that homeowners pay a lot of attention to, but it's a complex system that requires care and attention. From top to bottom the chimney is made up of a number of important components that are crucial to ensuring that your stove operates effectively and safely. The combustion gases are emitted to the outside through the firebox, the vent pipe and the chimney. This is essential to reduce carbon dioxide levels as well as prevent harmful emissions. To achieve this, the flue and chimney should be hot enough to move the gases from the fireplace without cooling. This can be achieved by using a wood-burning fireplace that has a high heat output and by adding new logs on a regular basis to the fire. Modern woodburning stoves are taller chimney than older systems to improve the drafting effect. This can be a problem in the event that your chimney's height exceeds the maximum allowed for your area. In this case the chimney could be competing with the house's stack for airflow, causing the gases to cool before they leave. This could result in a pause in the flow of gas, and an accumulation of creosote. One of the most frequent mistakes that homeowners make is to open and shut the door to the fireplace too often which can adversely affect combustion. It is important to keep the fireplace door as closed as possible, and only open it when you need to add firewood or ash. The door should not be opened for too long. This allows hot air from the stove to escape, making the wood cooler and more difficult to light. Other types of combustibles can create higher emissions, or even the possibility of a chimney fire. The fact is that woodburning stoves are built and optimised to burn firewood and not other types of combustibles. The flu To ensure that the airflow is proper, woodburning stoves require a flue that is the right size. Typically, the dimensions of the flue has to be at least 25 percent larger than the stove pipe (which connects the stove to the chimney) to allow enough space for smoke passage. A wood stove must be set on a non-combustible hearth with a clear area in front of the fireplace opening. Modern stoves come with catalytic combustion systems that reduces the amount of harmful byproducts released into the chimney. This feature is also able to improve the efficiency of wood stoves by burning a fire that generates more heat and less polluting. However, using other types of combustibles like coal, can cause issues, such as lower efficiency and higher emissions. It is crucial to use dry or seasoned wood when you are burning wood in your fireplace or stove. If your wood isn't dry or seasoned it will release high levels of creosote and water vapour into the chimney. This could lead to low flue temperatures, and even a chimney fire. Another way to avoid the possibility of a chimney fire is to have a professional inspection and clean your flue system on a regular basis. This includes the stovepipe, the chimney and the chimney itself. A dirty stove or system may lead to a poor draft in your chimney, which can cause carbon monoxide to accumulate in your home. This could be harmful for your family members and you should never allow it to happen. A good rule of thumb is to have your chimney and stove swept by a professional every year. This will keep your chimney and stove in good working order.
