A wood stove is a heating or cooking appliance capable of burning wood fuel, often called solid fuel, and wood-derived biomass fuel, such as sawdust bricks. Generally the appliance consists of a solid metal (usually cast iron or steel) closed firebox, often lined by fire brick, and one or more air controls (which can be manually or automatically operated depending upon the stove). The first wood-burning stoves were high-end consumer items and only gradually became used widely.
Advantages of Wood Stove
Placement Flexibility
A wood stove can be installed virtually anywhere in the home, providing there is a way to run a vent pipe to the outside of the house. This means you can zone-heat any room or space. A few well-placed stoves can almost completely replace a central heating system.
Economical Heating
Wood is an inexpensive fuel source. It costs less per btu than oil, gas or electricity. Homeowners who practice strategic zone heating in their homes can save hundreds of dollars in utility bills each year.
Exceptional Heating
The biggest advantage homeowners have with a wood burning stove is the quality of heat the unit gives off. Woods stoves operate on the principal of radiant heat, which warms an area faster and more efficiently than warm air being blown through a home’s vent system. The powerful heat from a wood stove radiates from all sides of the unit as well as the top, sending warmth in all directions.
Better For The Environment
Compared with using fossil fuels for heat wood is much more eco-friendly. It’s considered “carbon-neutral,” which means when it burns, it doesn’t add additional carbon dioxide to the environment. This is because in its natural state as a tree, wood absorbs carbon dioxide that’s in the atmosphere. During combustion, a balance is maintained.

Fireplaces and wood stoves
Wood stoves are often compared to fireplaces and where the application of wood might be similar as is the flue, they are quite different entities. Fireplaces are notorious for being very draughty and inefficient in homes. Heat leaks out through the flue and throughout the fireplace making it difficult to concentrate the heat in one contained area for optimal heating.
With a wood stove the gaskets and tight fitting nature enable the heat to be concentrated within the stove radiating from the unit. A contemporary wood stove can heat even a larger home far more effectively than a fireplace can.
Ventilation needs
The primary reason that a wood stove works so effectively is due to how the system utilizes air. Ventilation holes in the air control valve work to supply the firebox with necessary oxygen to maintain a hot flame. Flame control is enabled by opening and shutting the holes of the shaft. When the holes are fully open, the unit works at top capacity, but when the holes are closed off, the unit works with a lower flame. This cannot be accomplished with other forms of heating such as fireplaces.
Importance of materials
Not all materials conduct heat effectively. Heaters and wood stoves throughout the years have been made of a variety of different metals, but the one that has stood out the most is trusted cast iron. Iron maintains many properties that make it the best choice for any wood burning stove. It is convenient, cheap to use, an abundant metal, and last for many years, so manufacturing a stove out of cast iron means that the owner need only to invest in the initial purchase of the stove with annual follow up inspections for the life of the unit.
Apart from cast iron being the main functioning material, bricks add an additional heating element to the unit. Although heat easily absorbs and maintains within the unit, the bricks absorb even more heat in the bottom of the unit to maintain the heat within the fire box. Bricks also act as a way to maintain air flow through the unit for maximum flame. Without the bricks, the wood would simply sit on the bottom of the unit and making it difficult to achieve the necessary high temperature for effective heating.
Outflow
Contemporary wood stoves work simply by allowing air to flow into the fire box allowing the flame to rise to the necessary heat. Holding in heat is essential, but excess heat has to have a place to escape so an overabundance of pressure does not build within the unit. The addition of a blower system into modern units provides an effective outlet for excess heat to escape. With the blower engaged, the home can be heated more effectively, but this is not the only outflow area for the stove.
Like a standard fireplace, a contemporary wood stove maintains a flue to allow the smoke and excess heat to rise from the unit. Some wood stoves are fitted into existing fireplaces to maximize their efficiency and older chimneys require an interior flue tube to be inserted into the chimney.
Stand alone units allow the flue to come from the top or back of the unit, but no matter which style you have, proper cleaning is always essential. To clean the flue, a specialized chimney sweeping brush is used, or a professional cleaning service can be called in.
Breakdown of the process
A contemporary wood burning stove is essentially an easy device to understand. Wood is stacked in the firebox and lit to provide the initial flame. The ventilation into the unit brings in fresh air to fan the flames to the desired heat. Excess heat is sent out from both the flue and the blower to maintain the proper amount of pressure within the system. With additional air flow provided by the bricks in the system as well as their heat absorption capabilities, contemporary wood burning stoves have proven to be the most efficient and cost effective way to heat any home.
The stove itself
While it might sound obvious, your stove's size, design, and heat output are worth considering. The size should suit the room, ensuring adequate warmth without overheating. Still trying to decide? Check out our range of wood-burning stoves here.
Flue pipe
This will connect your stove to the chimney or external vent. Ensure the diameter matches the stove's outlet and is of the appropriate length.
Chimney cap
The chimney cap prevents rainwater, birds, and debris from entering the chimney. Plus, it helps to avoid downdraughts that could push smoke back into the home. They are typically made from a durable material like stainless steel.
Stove hearth
This non-combustible platform will sit beneath the stove, protecting your floor from embers and the stove's heat. Common materials include stone, granite, tile, or heat-resistant glass.
Chimney liner
Suppose you are connecting your stove to an existing chimney. In that case, a chimney liner will ensure the efficient exit of smoke and prevent leaks into the house. Choose a liner of suitable material, such as 316 or 904-grade stainless steel, and ensure it's the correct diameter.
Register plate
If you're using an existing chimney, this plate will seal off the base of the chimney, ensuring all smoke and fumes exit through the liner, and preventing heat loss up the chimney.
Fireproof mortar or sealant
This will seal gaps between the stove pipe and the wall or chimney. It'll ensure that no smoke or fumes leak into your room.
Carbon monoxide detector
Although it's not a direct installation tool, having a working carbon monoxide detector in any room with a wood-burning stove is crucial. This device will sound an alarm to alert you to any dangerous build-ups of this odourless gas.
How to Choose Wood Stove
Pick the right size wood stove
How big of a wood stove do you actually need? Many first time buyers instincts tell them to get the biggest stove available. Many wood stoves for sale come with huge fireboxes, 3, 4, and sometimes even 5 cubic feet, and correspondingly high heat outputs. But with modern insulation and the supplementary heat that most houses have now, these are usually overkill. Wood stoves are space heaters, and best for heating one zone of your home.
Decide if you want a freestanding stove or fireplace insert
There are essentially two types of wood stoves for sale: Free standing stoves and fireplace inserts. Freestanding stoves are typically installed in places without pre-existing masonry fire places, such as on a brick or tile floor or a store bought hearth pad. These stoves are available in many configurations including low to the floor with legs or elevated on a tower or pedestal.
Efficiency, efficiency, efficiency
Higher efficiency means less money spent on wood, less work chopping and hauling wood, and a product that is better for the environment. Older wood stoves tend to be inefficient and waste wood and many companies don’t publish their efficiencies as a result. Look for wood stoves for sale that have epa listed efficiencies of 70% or above to get the most bang for your buck.
Clean air and the new epa regulations
Gone are the days of smoke belching potbelly stoves. New clean air standards have set a high bar, restricting wood stove smoke emissions to only 2.0 grams/hour. But some manufacturers are still trying to squeeze out their old units before the deadline.
Catalytic or non-catalytic
When they were first introduced in the 80’s catalytic stoves, or wood burning stoves that use a catalytic combustor to reduce emissions, got a bad reputation. These initial poorly designed wood burning stoves were impossible to get started and used catalytic combustors that fouled and went bad after only a few seasons. New catalytic stoves don’t have those problems.
Go ahead and schedule that first chimney cleaning
All wood burning stoves need proper maintenance. We recommend getting your chimney swept at the beginning of every burning season, and maybe more frequently if you notice any problems. With more and more people switching to wood stoves every year, chimney sweeps usually fill their schedules up fast. After buying a wood stove, set that cleaning appointment early to make sure you keep burning happy.
Precautions of Wood Stove
While wood stoves can provide savings in heating your home, there are some do’s and don’ts to keep in mind to help avoid potential risks, such as burns, fire or carbon monoxide poisoning.
Keep children and pets away when you have a fire burning in the stove, as the outer surfaces of the stove and flue pipe are very hot. And keep anything that can burn at least 3 feet away from the stove.
Make sure you have working carbon monoxide and smoke alarms in your home. Alarms—Both fire and carbon monoxide—Should be located outside each sleeping area and on every level of the home.
Regularly remove ashes and properly dispose of them—But do not put them directly into a trash can. Ashes can take several days to cool completely. Instead, place ashes in a covered metal container located at least 10 feet away from buildings or vehicles.
Have your chimney cleaned and inspected regularly; ideally, at the start of the heating season. It is also a good idea to have it checked halfway through the burning season to check for any creosote buildup.
Have your wood stove inspected by a professional at least once every year for any wear and tear, especially to the door hinges, the combustion chamber and the connection between the stove and chimney.
Keep an eye out for any damage or unusual wear and tear, such as buckling, cracks in the glass, open seams or cracks in or corrosion of the metal.
How to Maintenance Wood Stove
Empty the ashpan
If hot ashes start to pile up in the ashpan they come into contact with the lower side of the grate. Having the grate sitting in hot ashes can cause it to distort and lose shape.
Clean the glass
Most modern stoves are fitted with an airwash sytstem to keep the glass clean as a vent at the top of the stove glass allows air to flow an dcreated a layer between the glass and the gases prodduced by the stove. If yours isn’t, clean your glass daily with a specialist cleaning product made for use on stoves or by using newspaper dipped in malt vinegar.
Check for rust
Again, probably not a problem you will encounter with a modern stove, but it’s worth mentioning nonetheless. If you do spot any rust, it’s better to act sooner to nip the problem in the bud.
Clean the baffle / throat plate
The area on and around the baffle plate is a favourite spot for soot and other deposits to gather. This not only makes your stove less efficient by blocking the flue, it is also potentially dangerous. These are flammable materials, after all.
Check rope seals
You’ll find your stove has specialist firerope around the door. This heat resistant rope forms a seal around the door to ensure it closes properly and to prevent excess air from getting into the stove.
Get chimney swept
Calling upon the services of a chimney sweep at least twice-a-year is a vital part of your stove maintenance. Failing to do so can lead to a build-up of creosote throughout the system and a subsequent risk of chimney fires.
Leave the door ajar during extended periods of non-use
If you’re not planning to use the stove for the summer or it’s going to be out of use for longer than a few days for any other reason, leave the door slightly open. This allows a flow of air through the system, which helps to stop corrosion.
