How To Recognize The Right Woodburning Stove For You
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 dangerous to your health. It's important to understand how these appliances work and to operate them properly.

Many modern stoves rely on a catalytic or secondary combustion to reduce their 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 simplest way to think about the firebox is that it's an open-air combustion chamber that has walls and doors. Most fireplaces come with prefabricated metal fireboxes or a masonry firebox. The kind of firebox you select will depend on your personal preferences as well as the kind of fireplace that you have.

Most wood-burning stoves use an air flow that is constant to generate the flame and burn the 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 caused by unburnt or incomplete combustion. The exhaust gases are transported through 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 cleaner and less polluting exhaust than traditional wood stoves that have no secondary combustion. Modern non-catalytic wood stoves are available however they are usually less efficient than those with secondary combustion that is catalytic.

Some wood-burning stoves have a backboiler that can be used to heat water, in addition to space heating. These stoves are referred to 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 a high water content. This can result in low flue temperatures, and an excessive accumulation of creosote in the chimney. This can cause chimney fires, which could harm your stove or be harmful to the health of your family members.

If you're looking for a professional to inspect your wood-burning stove, or perform any firebox repairs ensure that the chimney professional you choose is CSIA certified and has customer testimonials on their website. You can inquire about their prices and the kind of work they can perform.

The pipe for ventilation

Ventilation is required for wood stoves in order to remove fumes and keep the house healthy and warm. Ventilation helps remove carbon monoxide, nitrogen dioxide and excess moisture from the process of combustion. It also reduces the impact of air pollution and heat loss to the outdoor. Gas, pellet and wood stoves have different requirements for venting to adapt to the way they operate. Properly maintaining the stove's ventilation system annually is critical for safety and efficiency.

The ventilation system consists of the firebox as well as the ventilation pipe. The chimney and the vent pipe are used in conjunction to create draft, drawing smoke from the stove through the fireplace and into the outside air. Draft is caused by the variation in temperature and density between hot wood smoke and cold outside air. The more hot the temperature, the more smoke rises through the ventilation pipe and chimney.

The majority of modern wood stoves have been certified as low-emission units by EPA. This means that they produce significantly less pollution than older models, which contribute to global warming and other environmental issues. Most newer stoves also include pollution controls that limit the amount they emit while ensuring that the emissions are disposed of in an efficient manner.

Older stoves that have open flues create lots of carbon dioxide, which is an extremely poisonous gas and should not be allowed to escape into the home. This can happen if the chimney isn't clean or there is insufficient ventilation, which is why it is essential to install carbon monoxide detectors in your home.

Before installing a new or used wood stove, measure the distance from the point where the stove is on the floor to the chimney opening in the wall or ceiling. Multiplying this number by 2 will give you the shortest length of stovepipe you need. Single-wall or double-wall stovepipes, and you must 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 proper flame has been established and the combustion is stable. It is advised to stay clear of using wood logs in the stove since they could contain volatile chemicals that could cause the air vents to fail.

The chimney

The chimney is a complex system that requires careful care. From top to bottom, the chimney is made up of a number of important components, all of which are essential to ensure that your stove functions safely and efficiently.

The ventilation pipe, the firebox and chimney work together to release the combustion gases generated by your woodburning fireplace to the outside. This is crucial to reduce carbon dioxide levels and to prevent harmful emissions. To accomplish this the chimney and flue must be sufficiently hot to allow the gases to exit the fireplace without cooling. This can be achieved by using a wood-burning stove which produces a large amount of heat and by adding fresh logs frequently to the fire.

Modern woodburning stoves are built to work with a chimney which is higher than older models in order to get a better drafting effect. However, this could have its drawbacks in the event that the size of your chimney is greater than the maximum allowed for your location. In this situation, the chimney could compete with the stack of your house for airflow, causing the gases to cool before they leave. This could result in a pause in the flow of gas, and the formation of creosote.


One of the most common mistakes that homeowners make is to open and shut the fireplace door too often which can adversely affect the combustion. It's important to leave the door of your fireplace closed whenever possible, and only open it when you're required to add more ash or firewood. If you leave the door open for too long allows the hot air to escape from the stove, causing the logs to cool and more difficult to light. It releases volatile compounds that are not burned into the room.

Another common mistake that people make is using other kinds of combustibles with their woodburning stoves , which can result in more emissions or even a chimney fire. Woodburning stoves are designed and optimized to burn firewood. They are not suitable for other combustibles.

The flue

A woodburning stove requires an appropriately size flue to permit proper draft development and air flow. Typically, the size of the flue has to be at 25 percent larger than the stove pipe (which connects the stove to the chimney) to allow enough space for smoke passage. A wood stove should be placed on an uncombustible hearth with a clear area in front of the fireplace's opening.

Modern stoves have an element called catalytic combustor, which can cut down on the amount of harmful byproducts that are released into the chimney. This feature can increase the efficiency of wood stoves by burning a flame which produces more heat while emitting less pollutants. However, using different types of combustibles, like coal, could cause issues, including lower efficiency and higher emissions.

It is important to use dry or seasoned wood when you are burning wood in your fireplace or stove. If the wood isn't properly seasoned or dried, it could release a lot of water vapor into your chimney. This could result in low flue temperatures and even a fire in the chimney.

A professional can also help you avoid the possibility of a chimney fire by regularly inspecting and cleaning the flue system. This should include the chimney, stovepipe and the chimney itself to ensure all are in good working order.

A soiled stove or flue system can cause an unclean draft in your chimney, which can cause carbon monoxide to accumulate in your home. This can be harmful to your family members and should never be allowed to occur.

A good rule of thumb is to ensure that your stove and chimney are swept by a professional every year. This will also help to keep your chimney and stove operating efficiently.
