How to Properly Operate a Woodburning Stove
Wood stoves can provide an inexpensive and cozy way to heat the home. Smoke from wood stoves can be hazardous to your health. It is essential to know how these appliances function and to operate them properly.
Modern stoves utilize secondary or catalytic combustion to reduce emissions. But older stoves and open fires generate 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 to think of it as an open-air combustion chamber that has walls and an entrance. The majority of fireplaces come with a prefabricated metal or masonry firebox. The type of firebox you pick will depend on your preferences as well as the kind of fireplace you own.
The majority of wood-burning stoves utilize a constant flow of air to create the flame and burn the fuel. Fresh air is pumped into the stove via dampers which can be adjusted inside its doors. This lets the fuel be properly burned and also helps reduce toxic gases that are produced by incomplete or unburnt combustion. The exhaust gases are then taken up by the chimney and safely out of your house.
Modern stoves with catalytic secondary combustion use a special catalyst to reburn the unburnt gasses to create additional heat. This creates a cleaner and less polluting fume than traditional wood stoves without secondary combustion. Modern non-catalytic stoves are also available, but they're generally less efficient than stoves that have catalytic secondary combustion.
Certain wood-burning stoves come with a backboiler that can be used to heat water in addition to space heating. These stoves are called "hybrids" or "combination". They have been around since early 20th century.
Wood burning stoves should be lit with seasoned wood. Freshly cut (green) wood has a high moisture content and can result in low flue temperatures and excessive creosote buildup in the chimney. This can lead to chimney fires that destroy the stove, and can be hazardous to your family's health.
If you are looking for a professional who can inspect your wood-burning stove, or make repairs to your firebox, make sure that the chimney professional you hire has CSIA certification and provides testimonials from their customers on their website. It's also important to inquire about their pricing and what kind of work they perform.
The ventilation pipe
Ventilation is required for wood stoves in order to remove smoke and keep the home healthy and warm. 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 to the outdoors. Wood, pellet and gas stoves have different requirements for venting to adapt to the way they operate. It is crucial to keep the stove's venting system on an an annual basis for safety and efficiency.
The ventilation system is comprised of the firebox, the ventilation pipe and the chimney. The chimney and the vent pipe are used in conjunction to create draft, which draws smoke from the stove through the fireplace to the outside air. The difference in temperature and densities of the hot wood smoke and cold outside air creates draft. The higher the temperature, more smoke can rise through the pipe of ventilation and chimney.
The majority of modern wood stove s are certified by the EPA as low-emission units. They produce less pollution than older models which contribute to global heating and other environmental problems. Most newer stoves also include pollution controls that reduce the amount of carbon dioxide they emit while ensuring that the emissions are disposed of efficiently.
Older stoves with open flues generate more carbon dioxide. This is a poisonous, toxic gas and it cannot be escaped into your home. This could happen if the chimney is not properly maintained or if there is not enough ventilation, which is why it is essential to install carbon monoxide detectors within your home.
Before installing a brand new or used wood stove measure the distance from the point where the stove is on the floor to the chimney opening on the wall or ceiling. Multiply this number by two to find the minimum length of stovepipe you need. You can use single-wall or double-wall stovepipes, and you must be aware of the proper clearances from combustibles for either type.
The stove's air vent should be adjusted when it first starts to light up and maintained until a stable flame is established in the stove and its combustion process has stabilised. It is best to avoid using wood logs in the stove since they could contain volatile chemicals which can cause the air vents to malfunction.
The chimney
The chimney may not seem like something that people give a lot of thought to, but it's actually an intricate system that requires care and attention. The chimney is composed of numerous important parts that are essential for the safety and efficiency of your stove.
The combustion gases are vented to the outside by the firebox, the vent pipe and the chimney. This is essential to lower carbon dioxide levels and prevent harmful emissions. To accomplish this the chimney and flue must to be sufficiently hot to carry the gases out of the fireplace, without cooling. This can be accomplished by using a wood-burning stove that has a high heat output and by adding fresh logs frequently to the fire.
Modern wood-burning stoves have a higher chimney than older systems to increase the effect of drafting. This could be a problem in the event that your chimney's height exceeds the maximum height for your area. In this scenario, the chimney could compete with the stack of your house for airflow, causing gases to cool before leaving. This can cause a restriction in the flow of gas, and a buildup on creosote.
One of the most frequent mistakes that homeowners make is to close and open the door to the fireplace too often which can adversely affect combustion. It is crucial to keep the fireplace door as shut as you can and only open it when you need to add ash or firewood. Keeping the door open too long permits the hot air to escape from the stove, which causes the logs to get cooler and harder to light. It also releases unburned volatile compounds into the room.
Other types of combustibles could cause higher emissions or even an explosion in a chimney. Woodburning stoves were developed and optimized to burn firewood. They are not suitable for other types of combustibles.
The flu
To ensure proper air flow, a woodburning stove needs flues that are the correct size. The flue should be at least 25% larger than the pipe connecting the stove and chimney to allow adequate smoke passage. A wood stove must be placed on an uncombustible 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 also assist to increase the efficiency of a wood stove by burning a fire that produces more heat and emits less. Utilizing other kinds of combustibles than firewood, however, could cause issues, such as lower efficiency and higher levels of emissions.
It is important to use seasoned or dry wood when you are burning wood in your stove or fireplace. 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 possibly a chimney fire.
A professional can also assist you in avoiding a fire in your chimney by regularly inspecting and cleaning the flue system. This should include the chimney, stovepipe and chimney itself to ensure that they are all in good working order.
A soiled stove or flue system may lead to a poor draft in your chimney, which can cause carbon monoxide to build up in your home. This could be harmful for your family members and you shouldn't allow it to occur.
A good rule is to have your chimney and stove swept by a professional every year. This will also help to keep your chimney and stove working efficiently.
