Can You Have a Wood Burner Without a Chimney? A Complete Guide
Updated: 4 days ago
If you love the warmth, atmosphere and character of a real wood-burning stove but your home doesn't have a chimney, you may assume that a wood burner isn't an option.
The good news is that, in many cases, you can install a wood burner in a home without an existing chimney.
However, a wood-burning stove still needs a suitable way to safely discharge combustion gases. This means that, rather than simply installing a stove with no flue, you will generally need to install a purpose-built flue system.
In this guide, we explain how wood burners can be installed without an existing chimney, what is involved, the different flue options available and what you should consider before choosing a stove.
Can you have a wood burner without a chimney?
Yes. A wood burner can often be installed in a property without an existing chimney, provided there is a suitable route for a compliant flue system.
A chimney and a flue perform a similar essential function: they safely carry smoke and combustion gases away from the appliance and out of the building.
If your property doesn't have a traditional masonry chimney, a twin-wall insulated flue system can potentially be installed instead. This makes wood-burning stoves an option for a wider range of properties, including some modern homes, extensions, bungalows and properties where an existing chimney has been removed or isn't suitable for use. However, not every property will be suitable. The installation needs to be properly assessed and designed by a competent professional.
How does a wood burner work without a chimney?
A wood-burning stove without a traditional chimney can use a twin-wall flue system.
Unlike a conventional brick chimney, a twin-wall flue is a manufactured, insulated flue system designed specifically for solid-fuel appliances. The flue provides a controlled route for the combustion gases produced by the stove to travel outside.
Depending on the layout of your property, the flue may run:
Vertically through the room and roof
Through an upper floor and then through the roof
Externally up the outside of the property
Through an extension or single-storey part of the building before terminating above the roof
The exact route will depend on the property, stove position, roof design and applicable installation requirements.
What is a twin-wall flue?
A twin-wall flue consists of an inner flue pipe surrounded by insulation and an outer casing.
The insulation helps maintain the temperature of the flue gases while keeping the external surface of the system at a safer temperature.
This type of system is particularly useful where there is no existing masonry chimney because it provides a dedicated route for the stove's combustion gases.
Twin-wall flue systems can be used in a variety of installations, but they must be correctly specified and installed for the appliance and building.
Can a wood burner be installed in a house with no chimney?
In many cases, yes.
For example, you may have:
A modern home
Many newer properties were built without traditional fireplaces and chimneys. A wood-burning stove may still be possible if a suitable flue route can be created.
An extension
If you want a stove in an extension that doesn't have a chimney, a twin-wall flue may provide a solution.
A bungalow
A bungalow without a chimney may be suitable for a wood-burning stove, although the roof and flue termination still need to be carefully considered.
A property where the chimney has been removed
If an original chimney has been removed, it may be possible to install a new flue system rather than rebuilding a traditional masonry chimney.
A room without a fireplace
You don't necessarily need an existing fireplace to have a wood burner. The stove can potentially be installed in another suitable position, subject to the requirements for the appliance, hearth, clearances and flue.
Does a wood burner always need a flue?
Yes. A wood-burning stove produces smoke and combustion gases, so it needs a suitable flue system to safely discharge them outside.
This is an important distinction:
You can have a wood burner without an existing chimney, but you cannot simply have a wood burner with no flue. A flue is an essential part of a wood-burning stove installation. The flue also helps create the draw required for the stove to operate correctly.
What does a wood burner without a chimney look like?
One of the concerns homeowners often have is that a new flue will look unattractive.
Modern twin-wall flue systems are designed to provide a practical and relatively neat solution. Depending on the installation, the flue can be concealed within parts of the building or finished externally.
The visible section above the roof will generally be designed to provide an appropriate termination point while working with the proportions and appearance of the property.
A professional installer can discuss the available options before you decide where to position the stove.
Can the flue go through the roof?
Yes. In many installations without an existing chimney, the flue will pass vertically through
the roof.
This can be a particularly straightforward option when the stove is positioned below a suitable part of the roof.
The flue needs to be correctly designed and positioned in relation to the roof and surrounding structures. Its height and termination are important because the flue needs to discharge combustion gases safely and allow the stove to draw correctly.
Can the flue go through a wall?
A flue can potentially pass through a wall as part of the overall system, depending on the installation.
For example, an externally routed twin-wall flue may pass through the wall above the stove and then rise up the outside of the building.
However, the design cannot simply be based on the shortest route outside. The flue needs to meet the relevant requirements for clearances, termination height and positioning.
Your installer should assess the proposed route before installation.
Can you install a wood burner on an internal wall without a chimney?
Potentially, yes.
The absence of an existing chimney doesn't necessarily mean that a stove must be installed against an external wall.
A stove can sometimes be positioned more centrally within a room, with the flue travelling vertically through the property and exiting through the roof.
This can provide greater flexibility when planning your room layout.
However, the feasibility will depend on the building structure, available flue route, stove requirements, hearth and clearances.
What type of wood burner can you have without a chimney?
There isn't a special type of wood burner that magically doesn't need a chimney or flue.
Instead, many suitable wood-burning stoves can be installed using an appropriate twin-wall flue system where a traditional chimney isn't available.
The stove itself needs to be suitable for the proposed installation and fuel, and the complete system should be designed as a whole.
When choosing a stove, you should consider:
The size of the room
The required heat output
The available flue route
The position of the stove
The hearth requirements
Air supply
The property's construction
Whether the stove meets current requirements for the installation
Do you need a hearth for a wood burner without a chimney?
In most installations, a wood-burning stove will require a suitable hearth. The fact that the property doesn't have a chimney doesn't remove the requirements associated with the stove and its installation.
The type, size and construction of the hearth will depend on the appliance and installation.
This is something that should be considered at the planning stage rather than after the stove has been chosen.
Do you need an air vent for a wood burner?
Whether additional ventilation is required depends on factors including the stove's rated output and the characteristics of the property.
Modern homes can be particularly well insulated and airtight, so air supply is an important consideration when planning a stove installation.
Your installer should assess the property and appliance to determine the appropriate ventilation requirements.
Is planning permission required for a wood burner without a chimney?
Planning requirements can vary depending on the property and installation.
A new flue can alter the external appearance of a building, so it is important to establish whether any planning permission or other permissions are required before work begins.
There can also be additional considerations for listed buildings, properties in conservation areas and other protected buildings.
Building Regulations and installation requirements also need to be considered.
For this reason, it's important to get professional advice before purchasing a stove or starting installation work.
How much does it cost to install a wood burner without a chimney?
The cost can vary considerably because there is no single standard installation.
Factors that can affect the cost include:
The wood-burning stove you choose
The length and type of flue required
Whether the flue is internal or external
The number of floors it needs to pass through
Roof type and access
Hearth requirements
Any additional ventilation requirements
Structural work
Finishing and making good
The complexity of the installation
A property without an existing chimney may therefore require additional installation work compared with a straightforward existing chimney installation.
The best way to establish the likely cost is to arrange a site survey and receive a quotation based on your individual property.
Is a wood burner without a chimney safe?
A professionally designed and correctly installed wood-burning stove and flue system can be a safe heating and lifestyle feature.
However, installation is critical.
The stove, flue, hearth, ventilation and clearances all need to work together correctly. The system should be installed by an appropriately qualified and competent installer and maintained in accordance with the manufacturer's requirements.
Once installed, the stove and chimney or flue system should also be properly maintained and swept at appropriate intervals.
Can you have a wood burner in a new build?
A new-build property without a traditional chimney may still be suitable for a wood-burning stove. In fact, the absence of a chimney doesn't necessarily prevent you from including a stove in a new home. The key is to consider the flue route during the design and planning stage.
Planning the stove and flue position early can make it easier to create a neat installation and avoid unnecessary complications later.
If you're building an extension or renovating your home, it is therefore worth discussing your plans with a stove installer before construction work is completed.
Wood burner without a chimney: what should you consider?
Before choosing your stove, consider the following:
1. Where will the stove go?
Think about both the appearance of the room and the practical requirements of the installation.
2. Where will the flue go?
The flue route is one of the most important considerations in a chimney-free installation.
3. What size stove do you need?
Choosing a stove based purely on appearance can result in an appliance that is too powerful or not powerful enough for the room.
4. Is there enough space?
The stove needs appropriate clearances from surrounding combustible materials and other surfaces.
5. What type of hearth is required?
Your installer can advise on the appropriate hearth for your chosen appliance and installation.
6. Does the property have adequate ventilation?
Air supply needs to be considered as part of the installation design.
7. Are there any planning considerations?
Check this before installation, particularly if your property has restrictions or special status.
Can you have a wood burner without a chimney? The answer is often yes.
If you've always assumed that a wood-burning stove requires an existing chimney, it may be worth exploring your options.
A traditional chimney isn't necessarily essential - but a correctly designed flue system is.
A twin-wall flue can provide a practical solution for many properties without an existing chimney, allowing you to enjoy the warmth and atmosphere of a real wood-burning stove.
Every property is different, however, so the suitability of an installation should be assessed individually.
