Expert Help from The Team At The Fireplace Superstore
A wood-burning stove can bring wonderful warmth, character and atmosphere into your home. However, choosing the perfect stove involves much more than simply finding a design you like.
The stove must be suitable for the room, the property and the chimney or flue system. It also needs to be installed correctly, supplied with the right ventilation and used with suitable fuel.
At The Fireplace Superstore in Poulton-le-Fylde, Richard Bailey and our experienced team can help you understand the choices available. From traditional cast-iron stoves to contemporary freestanding models, inset wood burners and complete chimney-liner systems, we can guide you through the important points before you make your decision.
With knowledge passed down through generations and more than 40 years of experience at The Fireplace Superstore, our advice is based on many years and years of knowledge passed through the genreations.
Experiencing A Wood-Burning Stove?
There is nothing quite like the experience of sitting in front of a real wood fire. The authentic movement of the flames, the glow of real burning logs and the natural warmth create the perfect atmosphere that is difficult to reproduce with any other type of heating appliance.
Todays modern wood-burning stoves also offer several practical benefits:
A beautiful real and natural flame picture
Extensive powerful heat for the room
Traditional and modern contemporary designs
Freestanding, inset and cylindrical models
A centre point in your living space that can transform an interior
High-efficiency models that use more of the heat produced
The ability to heat a room independently of the central-heating system
The ideal stove can look equally at home in a country cottage, a period property, a modern extension or a contemporary purpose built new-build home.
Wood-Burning Stove or Multi-Fuel Stove?
Although they can appear very similar, wood-burning and multi-fuel stoves are designed differently.
Wood-Burning Stoves
A dedicated wood-burning stove is designed specifically for burning suitable dry logs. Wood normally burns best on a bed of ash, so the base of the firebox is generally designed with this in mind.
Multi-Fuel Stoves
A multi-fuel stove is designed to burn more than one permitted fuel type. It normally incorporates a raised grate and an ashpan because mineral-based fuels require air to circulate beneath the fuel.
Not every fuel can be used in every multi-fuel appliance. You must always follow the stove manufacturer’s instructions and comply with any smoke-control restrictions applying in your area. Also European stoves generally are only wood burning fires.
If your intention is mainly to burn logs, a dedicated wood burner may offer the firebox design and appearance you prefer. Richard and the team can explain the practical differences while showing you suitable models in the showroom.
Choosing the Ideal Heat Output
One of the most important decisions is selecting a stove with the correct heat output for your living space.
A stove that is too small may struggle to heat the space. A stove that is too powerful can make the room uncomfortable and may regularly be operated at a low setting. This can result in inefficient combustion, dirtier stove glass and increased deposits within the flue.
The heat requirement will depend on several factors, including:
The room’s length, width and ceiling height
The age and construction of the property
The standard of insulation
The number and size of windows
Whether the room is open-plan
The number of outside walls
The position of the stove
How the adjoining rooms are used
Simple online stove calculators can provide a rough indication, but they cannot fully assess an individual property. A professional survey is the best way to confirm the appliance and installation requirements.
I Frequent Question to Our Team, Does Every Wood-Burning Stove Need a Chimney?
Not necessarily.
A traditional masonry chimney can often be used, subject to inspection and any necessary remedial work. If there is no suitable chimney, it may be possible to install a factory-made insulated flue system.
This means that a wood-burning stove can sometimes be fitted in:
Modern homes without masonry chimneys
Extensions and open-plan rooms
Garden rooms, subject to suitability and regulations
Barn conversions
Renovated properties
Rooms where an external insulated flue route is possible
Every installation is different. The proposed route must be assessed carefully, particularly where a flue passes through floors, ceilings, roofs or close to combustible materials.
Flue Installation kits and twin wall flues can be viewed in-store.
Chimney Liner Explained?
A chimney liner creates a defined passage through which the stove’s combustion gases travel before leaving the property safely.
In an existing masonry chimney, a suitable liner may be installed to provide a continuous flue passage between the stove connection and the chimney terminal.
A liner can help ensure that the flue is correctly sized for the appliance and reduce the risk of gases finding their way through cracks, gaps or damaged sections of an old chimney. It can also help the flue warm up more effectively, which may improve the chimney’s performance and make maintenance more manageable.
A chimney liner is an important component, but it cannot compensate for an incorrectly selected stove, poor installation, inadequate ventilation or unsuitable chimney construction.
Does My Chimney Need Lining?
Not every existing chimney automatically requires a new liner. However, the chimney must be suitable for the appliance, sound throughout its length and capable of safely carrying the products of combustion outside.
Before installing a stove, the chimney should be properly inspected. Depending on its condition and history, the assessment may include sweeping, testing and a camera inspection.
A liner may be recommended where:
The existing chimney is damaged or deteriorating
Smoke or fumes could escape through gaps in the chimney
The chimney is too large for the selected stove
The internal surface is rough or difficult to maintain
Previous modifications have affected the chimney
Condensation or tar deposits are a concern
The stove manufacturer or installation design requires one
The chimney has not previously served a solid-fuel appliance
Testing shows that the existing flue is unsuitable
The final decision should be based on the condition of the chimney, the chosen appliance and the professional installer’s assessment.
Types of Stove and Chimney Liner
Different installations require different flue products. A liner must be suitable for the appliance, fuel, chimney and expected operating conditions.
Flexible Stainless-Steel Liners
Flexible stainless-steel liners are commonly used inside an existing masonry chimney. They are designed to be enclosed by the chimney and should not be used as an exposed chimney system.
Different grades and specifications are available. The installer will determine which type is appropriate for the appliance and installation.
Twin-Wall Insulated Flue Systems
Where a property does not have a suitable masonry chimney, a factory-made twin-wall insulated flue may provide an alternative.
These systems are made from connected, insulated sections and can sometimes pass internally through the building or externally up an outside wall. Their position, height, terminal and distance from combustible materials must all comply with the relevant requirements.
Other Lining Systems
Depending on the property and condition of the chimney, other specialist systems may be considered. These can include rigid liners and chimney-remediation products.
There is no single liner that is right for every home. The entire system should be designed around the chosen stove and the construction of the property.
Is the Diameter of the Liner Important?
Yes. The diameter of the liner or flue must be suitable for the stove and must not simply be chosen by guesswork.
An incorrectly sized flue can affect:
Chimney draw
Lighting and refuelling
Stove performance
Combustion efficiency
The cleanliness of the glass
The formation of deposits
The safe removal of combustion gases
The stove manufacturer’s instructions and the applicable building requirements must be followed. A flue should not be reduced below the permitted size simply because a smaller liner may be easier to install.
Chimney Draw and Stove Performance
A wood-burning stove relies on the chimney or flue to create sufficient draw. As the gases inside the flue become warmer, they rise and help pull fresh combustion air into the stove.
Poor draw can cause problems such as:
Difficulty lighting the stove
A weak or unstable fire
Smoke entering the room when the door is opened
Blackening of the glass
Slow combustion
Increased soot or tar deposits
Excessive draw can also be undesirable because it may cause the fuel to burn too quickly and make the stove difficult to control.
Chimney height, internal diameter, bends, insulation, terminal position and surrounding buildings or trees can all affect performance. This is another reason why a proper survey is so important.
Ventilation and Air Supply
Every wood-burning stove needs a reliable supply of air for combustion.
Modern homes and properties that have been extensively insulated can be particularly airtight. Extractor fans, cooker hoods and mechanical ventilation systems may also influence the air pressure within the building.
Depending on the appliance and property, a dedicated air vent may be required. Some stoves can be connected to an external air supply, although the suitability of this arrangement depends on the individual model and installation.
A stove must never be fitted without checking the ventilation requirements. Insufficient air can affect combustion and prevent the chimney from operating safely.
Hearths and Distances from Combustible Materials
A wood-burning stove must stand on a suitable non-combustible hearth. The required construction and dimensions will depend on the appliance, installation and floor beneath it.
The stove and flue must also be positioned at safe distances from combustible materials. These may include:
Timber walls and studwork
Wooden beams
Flooring
Furniture
Shelving
Curtains
Television cables and electrical equipment
Decorative wall finishes containing combustible materials
Clearances vary between stove models, so the manufacturer’s instructions must always be checked.
A material that looks like stone or masonry may still be fixed to timber or another combustible structure. The complete construction behind the visible finish must therefore be considered.
Can a Television Be Fitted Above a Wood-Burning Stove?
This requires considerable care.
Wood-burning stoves and their flue pipes can produce substantial heat. A television, soundbar, electrical cables or media equipment placed above or close to a stove may be exposed to temperatures outside the manufacturer’s recommended limits.
The design must take account of:
Heat rising from the stove
The temperature of the flue pipe
Required clearances from combustible materials
The construction of the chimney breast
The television manufacturer’s instructions
Cable routes and electrical connections
Suitable ventilation around the television
The use of an appropriately designed mantel or heat deflection, where permitted
A conventional electric-fire media wall cannot simply be copied and fitted around a wood-burning stove. It requires a properly designed, regulation-compliant construction and individual professional assessment.
Smoke-Control Areas and DEFRA-Exempt Stoves
Many towns and cities are located within smoke-control areas.
In a smoke-control area, wood may only be burned in an appliance that has been approved for that purpose, commonly described as a DEFRA-exempt stove. The appliance must be operated correctly and only with the fuel permitted by its instructions and exemption.
Do not assume that every modern stove is automatically suitable for use in a smoke-control area. Check the exact appliance and contact your local authority if you are unsure whether your property is included.
Our team can help you identify suitable stove models, but responsibility for complying with local smoke-control rules remains important.
Ecodesign Wood-Burning Stoves
Modern Ecodesign stoves are engineered to meet stricter standards for efficiency and emissions than many older appliances.
Depending on the model, features can include:
Improved control of combustion air
More complete burning of the gases produced
Higher seasonal efficiency
Reduced particulate emissions
Cleaner-burning firebox technology
Airwash systems designed to help keep the glass clearer
Ecodesign does not mean that a stove produces no emissions, nor does it remove the need to use dry fuel, sweep the chimney and operate the appliance correctly.
The stove, fuel, chimney and user all contribute to its real-world performance.
Choosing and Storing Firewood
The quality of the logs you burn has a major effect on stove performance.
Wet or unseasoned wood can be difficult to light and produces less useful heat because energy is used evaporating the moisture. It can also create more smoke, blacken the glass and increase deposits inside the stove and chimney.
For best results:
Purchase dry, suitable firewood from a reputable supplier
Look for properly certified, ready-to-burn logs where applicable
Follow the stove manufacturer’s fuel instructions
Store logs in a dry and ventilated location
Keep stored wood protected from rain
Allow air to circulate around the logs
Never burn painted, treated or manufactured timber unless expressly approved
Do not burn household rubbish, plastics or waste materials
A moisture meter can provide a useful indication, but it should be used correctly. Split a log and test the freshly exposed internal face rather than only measuring the outside surface.
Why Burning Wet Wood Causes Problems
Wet wood may appear cheaper, but it normally gives poorer results.
Burning logs with excessive moisture can lead to:
Reduced heat output
Difficulty lighting and maintaining the fire
Excessive smoke
Blackened stove glass
More soot and tar in the flue
Increased chimney maintenance
Greater risk of chimney deposits igniting
Complaints from neighbours
Correctly seasoned dry wood burns hotter and more cleanly, helping the stove and chimney reach their proper operating temperatures.
Lighting a Wood-Burning Stove
Always follow the instructions supplied with your particular stove. A typical lighting procedure may involve placing suitable kindling and a firelighter in the firebox, opening the required air controls and establishing a bright fire before gradually adding larger logs.
Important points include:
Use only suitable firelighters
Never use petrol, methylated spirits or other accelerants
Do not overload the firebox
Allow the flue to warm up
Add logs gradually
Keep the stove door closed during normal operation
Adjust the controls as described by the manufacturer
Do not leave the air controls fully open for longer than necessary
Never operate the stove with damaged glass or door seals
Some manufacturers recommend a top-down lighting method because it can warm the flue gradually and establish cleaner combustion. Follow the procedure provided for your appliance.
Avoid Slumbering the Stove
A common mistake is closing the air controls too far in an attempt to make logs burn all night.
Starving the fire of air can cause incomplete combustion, reduced efficiency, black glass and increased soot or tar within the chimney.
A modern stove should normally be operated with visible, controlled combustion in accordance with its instructions. The fire should not be left smouldering for long periods.
Correct operation helps you obtain more useful heat from the fuel while keeping the stove and flue cleaner.
Carbon-Monoxide Alarms
A suitable carbon-monoxide alarm is an essential safety measure for a room containing a solid-fuel appliance and must be positioned in accordance with the applicable requirements and manufacturer’s instructions.
An alarm is an additional safeguard; it is not a substitute for:
Correct stove installation
Suitable ventilation
A sound chimney or flue
Regular chimney sweeping
Appliance maintenance
Proper fuel and operating practices
Test the alarm regularly and replace its battery or the complete unit as directed by the alarm manufacturer.
If a carbon-monoxide alarm activates, stop using the appliance, ventilate the property, leave the affected area and seek appropriate emergency and professional assistance. Do not use the stove again until the cause has been identified and corrected.
Chimney Sweeping and Maintenance
A wood-burning stove and chimney require ongoing maintenance.
The chimney should be swept at intervals appropriate to the appliance, fuel and frequency of use. Many regularly used wood-burning systems require sweeping at least twice during the burning season, but the correct schedule should be agreed with a competent chimney sweep.
Maintenance may include:
Sweeping the chimney or liner
Removing deposits from the stove and flueways
Inspecting firebricks and internal components
Checking door rope seals
Inspecting the baffle or throat plate
Checking the flue connection
Inspecting the chimney terminal
Servicing air controls and moving components
Checking the carbon-monoxide alarm
Looking for corrosion, damage or signs of overheating
Always allow the stove to become completely cold before cleaning it, and follow the manufacturer’s maintenance instructions.
What Is a Chimney Fire?
A chimney fire can occur when combustible deposits inside a chimney or liner ignite.
Possible warning signs include:
A loud roaring sound
Unusual vibration
Flames or sparks coming from the chimney
An intense increase in temperature
A strong smell of burning
Sections of the chimney breast becoming excessively hot
If you suspect a chimney fire, call the fire and rescue service. Do not use the stove or chimney again until the complete system has been professionally inspected and confirmed safe.
Burning suitable dry fuel, operating the stove correctly and having the chimney swept regularly can reduce the build-up of dangerous deposits.
Can an Old Fireplace Opening Be Used?
Many traditional fireplace openings can be adapted to accommodate a stove, but their condition must be assessed first.
Work may be required to:
Open up a previously reduced fireplace
Remove unsuitable materials
Repair or rebuild parts of the chamber
Install a suitable lintel
Prepare the chimney for a liner
Construct or extend the hearth
Add ventilation
Fit a register or closure plate
Create suitable access for sweeping
Finish the chamber with non-combustible materials
Older properties can contain hidden alterations, damaged flues or combustible materials close to the opening. These issues may only become apparent during a detailed survey or once previous coverings are removed.
Do New-Build Homes Need Special Consideration?
Yes. Newer homes are often well insulated and relatively airtight, which can affect the air available to the stove.
A new-build installation may require:
A stove compatible with the property’s air-tightness
A dedicated external air supply
Careful coordination with mechanical ventilation
A factory-made insulated chimney system
Appropriate floor and wall protection
Strict attention to combustible materials
Approval from the housebuilder or warranty provider where applicable
The installation should be planned before decorative work is completed. This helps avoid expensive alterations later.
Professional Installation and Certification
A wood-burning stove is a combustion appliance and should be installed by a suitably competent professional.
In England and Wales, qualifying work can normally be self-certified by an installer registered with an appropriate competent-person scheme. Alternatively, an application may need to be made through local-authority building control.
Following installation, the customer should receive the relevant commissioning and compliance documentation. The appliance, controls, safe operation, fuel requirements and maintenance schedule should also be explained.
Keep all certificates, instructions, guarantees and sweeping records. They may be important for insurance, future maintenance and the eventual sale of the property.
What Happens During a Stove Survey?
A proper survey may consider:
The dimensions and construction of the room
The required heat output
The proposed stove position
The condition and route of the chimney
Whether a liner is needed
Flue diameter and height
The chimney-terminal position
Hearth construction
Distance from combustible materials
Ventilation requirements
Access for installation and future sweeping
The presence of extractor fans
Smoke-control-area requirements
The type and condition of the property
Photographs and approximate measurements can be helpful during an initial showroom discussion, but they do not replace a professional site assessment.
Questions to Ask Before Buying a Wood-Burning Stove
Before making your final choice, consider the following:
Is the stove output appropriate for my room?
Is it a wood burner or a multi-fuel appliance?
Is my property in a smoke-control area?
Is the exact model DEFRA exempt if required?
Does my chimney need lining?
What type and diameter of liner or flue are required?
Does the room need additional ventilation?
Is the hearth suitable?
Are the distances from combustible materials achievable?
Who will install and certify the appliance?
How often will the chimney need sweeping?
What fuel does the manufacturer permit?
What guarantee applies to the stove and liner?
Will the installation affect my home insurance or property warranty?
Frequently Asked Questions
Can I install a wood burner in a house without a chimney?
It may be possible to use a properly designed insulated flue system. The route, height, clearances and terminal position must be assessed for the individual property.
Must every chimney have a liner?
No. However, every chimney must be suitable, sound and correctly sized for the appliance. Inspection and testing will determine whether lining or remedial work is required.
Can I fit a stove myself?
A stove installation must comply with the relevant building requirements. Using a suitably registered competent installer is generally the simplest way to obtain a correctly commissioned and certified installation.
Can I burn any wood?
No. Burn only suitable dry wood permitted by the appliance manufacturer. Never burn painted or treated timber, household waste, plastics or other unsuitable materials.
Why does my stove glass turn black?
Possible causes include wet fuel, insufficient combustion air, low-temperature burning, poor chimney draw, overloading or incorrect operation. The appliance and chimney may need checking if the problem continues.
Why does smoke enter the room when I open the door?
Possible causes include poor chimney draw, a cold or restricted flue, inadequate ventilation, extractor-fan interference, unsuitable weather conditions or opening the door too quickly. Stop using the stove if fumes continue to enter the room and arrange a professional inspection. Our installation team can help with any issues with a wood burning stove.
How long does a chimney liner last?
There is no single lifespan that applies to every liner. Longevity depends on the liner specification, installation quality, fuel, stove operation, chimney conditions and maintenance. Guarantees also vary, so check the terms carefully and keep evidence of regular sweeping.
Can a stove provide heat for the whole house?
Most conventional wood-burning stoves are primarily intended to heat the room in which they are installed. Heat may travel into adjoining areas, but this should not be confused with a designed whole-house heating system. Many European wood burning stoves have a flue option where a flexible pipe can be connected to an outlet on top of the stove and then situated in to a vent in to another location in the home to help distribute some of the heat.
