A negative narrative is being unfairly manufactured around the wood-burning stove industry, by anti-woodburning groups such as the ‘London Wood Burning Project’ and ‘Clean Air Hub’.
The TRUTH is that UK PM 2.5 emissions have been steadily decreasing over the years despite record stove sales. In this blog, we summarise the flawed data and unfair generalisations anti-woodburning groups are using.
1/ What do they mean by ‘Wood-Burner’ & ‘Domestic Burning’?
They combine emission sources (Inefficient Old Stoves, Open Fires, Bonfires and Modern Ultra Efficient Stoves) to create a bigger more impactful number, and then claim 17% of London’s emissions come from ‘domestic wood burning’ or ‘wood burners’. Catch-all terms the public understandably associates most often with wood-burning stoves – especially because they create ad campaigns prominently featuring images of wood stoves. However, the actual contribution of modern wood-burning stoves is estimated by the UK government’s official figures at just 1-2%! (1)
2/ They use Weak Science & Manipulate Data
Imprecise methodology
Their data collection relies heavily on estimations and ambient air sampling, offering a blurry picture at best. Traffic, construction, industrial processes and even natural dust all contribute to PM2.5 and cannot reliably be controlled in their methodology.
(Pg.20 of the LWBP report)
Walking around with modified backpacks does not allow them to distinguish in any way what the source of PM2.5 is in a given area.
Small sample sizes and insufficient testing equipment.
One of the major studies often cited, is by Rohit Chakraborty et al, and based on a sample size of just 19 homes that took measurements using, as they admit, “low-cost air quality monitors” (7)
Manipulated data
They exclude critical data to stack the narrative against wood-burning stoves. For example, comparing the emission rates between wood stoves and HGVs has caused unnecessary concern.
Closer inspection revealed their data excluded brake and engine wear and in fact, just one Euro 6 HGV produces 13 times more PM2.5 emissions than an Ecodesign wood-burning stove over the course of a week’s real-world use. Furthermore, emissions from HGVs are emitted at ground level (nearer head height) while wood smoke is dispersed more safely, higher up via a chimney flue. (8)
3/Claims Based on Their Opinion NOT Fact
In the bottom left-hand corner of every page of the London Wood Burning Project report you can see the following disclaimer:
“This report is the independent expert opinion of the author(s)”
Firstly, anyone can claim to be an expert, however, the key word here is ‘opinion’.
Well, the SIA has commissioned extensive independent research which casts serious doubt on the estimations and ‘opinions’ provided by anti-woodburners (6)
At the time of writing the original blog post (11/01/2024) on a very cold winter’s day when wood stove usage would typically be higher, here is the PM2.5 picture for the UK taken from DEFRA’s official website.
So, when the anti-woodburners say 17% of emissions. It is 17% of a very low amount in the first place. Then, remember modern wood-burning stoves are just 1-2% of that low amount.
5/ Modern Stoves Equal Lower Emissions with HUGE Benefits
-They produce heat reliably for sustained periods and are unaffected by the weather.
-Allowing them to work in tandem with wind, solar and other green heating solutions. A stove makes these great technologies more viable – They are not in competition with each other.
-Energy Security – a wood-burning stove is an ideal emergency/low-frequency heat source.
-Wood stoves are essential for off-grid, sustainable, eco-friendly living. Perfect for yurts and other tiny home accommodations.
-Wood is a carbon-neutral fuel as it gives off the same amount of carbon whether it is burnt or decays naturally. The carbon released from burning wood is balanced out by the carbon absorbed by the tree during its lifetime.
-Wood fuel can be sourced locally without fracking and deep-sea oil drilling.
-A good quality stove can last many decades and provide an affordable source of heat for low-income households.
-The right to repair. The majority of components used within a Charnwood stove are modular and can be replaced when or if they wear out further extending the life of your stove.
-There are significant well-being benefits from using a wood-burning stove. Read about the Charnwood wellbeing survey and all the amazing benefits of owning a stove for your wellbeing.

Read on to learn about the Charnwood Stove Accessory Survey and the other top wood-burning stove accessories!
The results
A woodstove is a wonderful addition to the home. Those of you who are new owners will be starting to notice how much more you are enjoying the colder evenings than before. What you will also notice is the ritual of building and maintaining a fire is much easier with the right tools.
The answers to the following questions will provide some ideas about which stove accessories you should consider next!
What is the most popular wood-burning stove accessory?
The results in the graph above show that the trusty Stove Pipe Thermometer is the most popular wood-burning stove accessory with 29% of the vote. 99% of respondents also found it easy to use.
Stove Pipe Thermometer
It’s perhaps no surprise that the trusty Stove (Flue) Pipe Thermometer is the favourite accessory of stove users. It is a crucial tool for conscientious wood stove users who prioritise safety and efficiency.
The ideal wood burning temperature range is between 140 and 240 degrees Celsius (284 to 464 degrees Fahrenheit) which avoids damage to the stove and a potential fire hazard from creosote buildup.
How to adjust the fire temperature?
To reach a sufficient temperature, ensure a good draft, use seasoned wood and build the fire correctly ensuring your fire burns hot enough. To reduce the temperature of your fire when in use, you can close the air vents.
Which of the following do you consider ‘Must Have’ stove accessories?
Here are some quotes from survey participants relating to the top 7 ‘Must-Have’ stove accessories.
Log Storage/Basket
“Having a full wood basket during these crazy days makes me feel safe and secure, whatever happens I know I have heat and hot water and light.”
“Keeps all the logs tidy and looks great beside the stove. Also useful for carrying in logs from the store outside!”
“Add to the aesthetics of the fireplace and is obviously useful for keeping wood supplies topped up.”
“It reminds me of my grandparents’ days as they always had one. It also keeps all my logs safe and tidy away from the children.”
“A good quality basket enhances the look of the stove as well as being practical.”
“My log basket really enhances both the look and the “feel” of my log burner.”
“Keeps my living room very tidy. Really neat and elegant looking item. Sturdy and robust”
“Looks great and saves having to leave the room/ go outside for logs.”
“It adds to the ambient feeling of the room when partially or fully loaded but I suppose more importantly it stops me from having to pop outside too frequently to get more logs, thus letting me enjoy the fire uninterrupted.”
“It saves us fighting about who is going to get more logs when it’s cold!”
“Ensures I always know the temperature my stove is at as to whether I need to add more fuel or calm it down.”
“Makes it so much easier to see if my fire is working at optimum temperature and if I need to adjust amount of wood/air flow.”
“Because it allows us to check whether we are burning at too hot a temperature or too cool. We use both hardwood and softwoods so it would be difficult to know without this vital tool.”
“It means that I always burn my logs in the most economical and environmentally friendly way.”
“I hadn’t realised just how hot the stove gets at full output making this an essential piece of it when topping it up with firewood.”
“It allows me to regulate my stove temperature to maximise the life of the stove and have efficient burning of my wood”
“Ensures the fire is hot enough to keep down the accumulation of creosote. Wouldn’t be without it!”
“I constantly use it to check that the stove is burning in its optimum range for efficiency and to prevent damage and tarring.”
“Invaluable, the little thermometer lets me know when the fire is at optimal temperature and I can then maintain that temperature throughout operation. Probably helps conserve wood too, a great bit of kit.”
“Just gives you so much information in regards to heat output from different fuel types, different wood species, hard woods, softer woods. It really allows you to dial in the stove to get the best from it.”
“This provides us with an idea of how well the stove is burning. For example, over the last two years we have been testing wood purchased from sellers and our own seasoned wood and the stove pipe thermometer gives us a real measure of the heat output (even though most of the time, we can tell the difference ourselves based on how nice the room feels). It also helps us regulate the flu for optimal burn. We learned a lot using the stove pipe thermometer about our stove and the wood we burn.”
“It reassures me that I have the right burn, low emissions and great heat output.”
“As an engineer I love indisputable visual indication of when things are operating correctly! Such a simple device and has definitely altered how we ‘set’ our stove.”

Stove Gloves
“Without them it would be very difficult and dangerous to use the burner”
“Only burn your fingers once to realise they are useful!!!”
“Provides confidence in 100% protection when refueling the stove.”
“Really effective and protects hands while loading logs”
“Just love them, total safety when loading the stove”
“Because it stops me blistering my hands.”
“Offers safety when handling logs, opening & closing stove and promotes attention to avoiding burns.”
“Makes me feel safe when stove has become very hot”
“They just make life so much easier handling logs and placing logs in the stove. No splinters or burns!”
Watch this space – Charnwood stove gloves are on the way!
Dustpan & Brush
“It makes emptying the stove so much easier and cleaner, the house is relatively dust free after clearing.”
“It helps to keep the room relatively dust free”
“Keeping the hearth clean and tidy stops ash and debris, from the stove and wood pile underneath it, from spreading to the floor and messing up the room.”
“Whenever the stove is used it is necessary to clean up small amounts of ash that fall out. The brush and pan are thus used very frequently.”
“The dustpan & brush makes removing the Ash so much easier, our charnwood is used every day from October to February so we collect a lot of Ash which we use as compost. We have other accessories but they don’t see as much use as the pan & brush.”
Poker
“An absolute must have accessory to reposition burning logs and coal.”
“Can re-arrange wood in the stove when going, safely.”
“Brilliant for getting fire going”
“I like poking the fire! Breaking it down to a bed of hot burning wood so I can get more fuel in!”
“I can poke the logs to get maximum burn.”
“Great to look at, well made and does the job perfectly.”
“You can move the logs about to create space and so regulate heat a bit better.”
“It’s so satisfying prodding at red hot embers on a freezing cold evening and feeling the heat on your face”.
“Great quality and have stood the test of time with good amount of use. Quality product.”
“We have a wrought-iron poker made by a friend from years ago..handle in the shape of a hare’s head..love it, wasn’t cheap but a real beauty.”
“Simple basic tool allowing rearranging of fuel to ensure even burning and helping keep glass door clean.”
“Get the fire going. Can push the logs back into the fire so they burn probably.”
“Easy to use. Metal. Compact. Stops dust flying around. Carry handle is useful.”
“Great 4 carrying ashes out on a windy day.”
“Ease of use in keeping ash contained and not flying all over the place.”
“Allows dust free disposal of ash.”
“I have two Charnwood stoves. One has the ash bin/carrier and the other doesn’t. It’s SO difficult to get the ash out of the stove that doesn’t have the ash bin/carrier.”
“It is a safe and clean way of dealing with the only downside to a log burner, the ash.”
“Ease of emptying.”
“Makes it easy to empty ashes no fear of dropping them all over the floor.”
“Makes it more convenient to remove ash over several days without having to fill smaller bin bags thus reducing plastic waste.”
“Easy to use with minimal dust released when moving around can hold at least 1 month’ worth of ash.”
“Simplifies the worst job – cleaning out the ashes and getting them to the bin without being covered in ash from head to foot in a gust of wind. Neat to store, fits the ashcan perfectly and contains the dust when you tip the ashes in.”
Surprisingly only 23% of those surveyed own a moisture meter. We consider a moisture meter a must-have stove accessory to ensure wood is properly seasoned before burning and we urge you to get one!
It is very important to only burn wood with a moisture content of 20% or less. This will keep harmful emissions to a minimum and significantly improve efficiency, while protecting your stove and chimney – saving you money!
Look out for the Woodsure Ready to Burn label which guarantees a moisture content of 20% or less.
For a list of approved firewood sellers in your area click here.
Here are what some moisture meter owners had to say:
“I know I’m complying with byelaws and also prolonging the life of my Island 2 stove”
“Because I like to know that the logs I’m burning are dry and safe to use”
“Allows us to keep the stove clean by making sure we only burn the driest wood”
“This plus thermometer can’t really be replicated using non specialist tools.”
“It means I know when I can burn the wood that I’ve collected myself from the neighbourhood.”
“Vital for the whole seasoning process.”
“Especially Important given that the cost of kiln dried logs has doubled compared to this time last year!”
“I know I’m complying with byelaws and also prolonging the life of my Island 2 stove”
“Because it saves me burning wood which is too wet. Genuinely get a buzz when I ‘detect’ anything too moist on my meter!”
If you are seasoning your own wood, make sure you test it with a moisture meter before burning. You can get yours here.

Finally, thank you to everyone who took part in the survey!
We don’t enjoy having to react to media sensationalism, however, there are times when it feels important to set the record straight. A negative narrative is being unfairly manufactured around the wood-burning stove industry, by anti-woodburning groups such as the ‘London Wood Burning Project’ and ‘Clean Air Hub’. Their campaigns repeatedly use misleading claims and stats to scare the public and they refuse to answer questions directly when challenged.
Therefore, we feel it is a duty to set the record straight, so people don’t succumb to the haze of misleading information out there. In this blog, we will shed light on some of the flawed data and unfair generalisations anti-woodburning groups are using.
What do they mean by wood-burner?
The campaigns paint a distorted picture, often using anxiety-inducing imagery and negative attention-grabbing headlines based on sweeping generalisations and weak or inaccurate data. They continue to mislead the public using stats that lump modern wood-burning stoves in with outdated, inefficient models, open fires and bonfires. It’s like saying cyclists are equally to blame for traffic congestion/emissions as lorries and private cars just because they all use wheels!
They combine emission sources for a more impactful number, and then claim 17% of London’s emissions come from ‘domestic wood burning’ or ‘wood burners’. Catch-all terms the public understandably associate most readily with wood-burning stoves – especially because they create ad campaigns which prominently feature images of wood stoves. However, the actual contribution of modern wood-burning stoves is estimated by the UK government’s official figures at just 1-2%! (1)
Differentiating between wood-burning practices is vital for progress
Firefly London points out: “The irony of the billboard placement is that London’s tube network has appalling air quality, with PM 2.5 readings peaking at 600-700 ug/m3 – that’s 100 TIMES MORE PARTICULATES than an average London street…”
It is essential to differentiate between various forms of wood-burning. Chief Medical Advisor Chris Whitty in his report acknowledges this saying, “For air pollution emissions, there is substantial difference between the different open fire and stove designs, the age of the appliance and how well maintained it is, and the moisture content of the wood, for those who want to burn wood.”(2)
While Ecodesign-compliant stoves are up to 90% more efficient than an open fire, ClearSkies Level 5 stoves, are even better still. They surpass Ecodesign standards, offering a further reduction in emissions by up to 30%! (3)
This is where the anti-woodburning strategy is so incredibly counterproductive. In London 70% of wood burning still occurs on open fires.(4) If people were widely encouraged to switch to one of the many modern and efficient wood-burning stoves available, it would massively reduce urban PM 2.5 emissions. Just think, the emissions of 70% of London Wood burning could be reduced by 90%!
Modern wood-burning stoves could help London reduce open-fire emissions by 90% !
PM 2.5 comes from such a wide array of natural and man-made sources that a zero-emission world is impossible! The best we can do is reduce them as much as possible while maintaining our ability to heat our homes. That is exactly what modern wood-burning stoves help achieve.
If improvements were what the anti-woodburning brigade was truly after, it doesn’t make sense to ignore the vast advancements in clean-burn technology now defining modern wood-burning stove heating. They are the ones being ‘careless’.
PM 2.5 perspective: How stoves can HELP improve indoor air quality
This is also totally misleading. We could draw on our sources, but more powerfully we can draw on the London Wood-Burning Project’s own report as a rebuttal to this one.
On page 71 of their 127-page report (5), we find the page titled Key Findings. Below are 3 crucial pieces of information from this page:
1/ Use of the clearSkies Level5 stove (which is Ecodesign compliant) demonstrated some benefits for indoor air quality. Indoor PM2.5 did not increase when adding fuel to the stove once lit… At times there was actually a decrease in indoor concentrations of PM2.5 when adding fuel.
As we have long pointed out, a properly functioning modern wood stove draws particulates out of the room and up the flue, helping improve air quality and ventilation in the home. The stove used in this study was our Charnwood C-Five.
2/ Increases in pollutant concentrations may be more affected by participant technique or specific airflow characteristics of an individual appliance, rather than to the type of appliance or fuel.
We always encourage best stove practices and will continue to do our level best to educate new and existing customers and beyond.
3/ However, the biggest increases in PM2.5 concentrations indoors did not relate to indoor wood or solid-fuel burning but instead were a result of cooking, especially frying, grilling and use of the oven, and particularly when the extraction fan was not used.
This really provides perspective on the issue of PM 2.5 in the home. A slice of burnt toast or your Sunday lunch can contribute far more than a wood-burning stove.
It’s a shame they don’t plaster these findings on a bus or large poster.
A lack of scientific rigour
Imprecise methodology
“The results were compared to modelled wood and solid-fuel burning emissions to identify areas where the measurements match well with predictions or where measurements may provide evidence of solid-fuel burning that were not predicted by the model.” (pg.9 of the LWBP report)
They do not sufficiently differentiate between the different sources of ‘solid fuel burning’. Data collection relies heavily on estimations and ambient air sampling, offering a blurry picture at best. Traffic, construction, industrial processes and even natural dust all contribute to PM2.5 and cannot reliably be controlled in their methodology.
(Pg.20 of the LWBP report)
Walking around with modified backpacks does not allow them to distinguish in any way what the source of PM2.5 is in a given area.
Small sample sizes & poor testing equipment
One of the major studies often cited, is by Rohit Chakraborty et al, and based on a sample size of just 19 homes that took measurements using, as they admit, “low-cost air quality monitors” (7)
Manipulated data
Data is also often twisted and cherry-picked to bolster a blinkered argument. For example, comparing the emission rates between wood stoves and HGVs has caused much unnecessary concern.
Closer inspection revealed their data excluded brake and engine wear and in fact, just one Euro 6 HGV produces 13 times more PM2.5 emissions than an Ecodesign wood-burning stove over the course of a week’s real-world use. Furthermore, emissions from HGVs are emitted at ground level (nearer head height) while wood smoke is dispersed more safely, higher up via a chimney flue.
The SIA say, “ The claims are based on simplistic calculations using permitted rates of emission and do not consider either real world use or non-exhaust emissions. Furthermore, these permitted emissions rates rely on vastly differing measurement protocols and techniques. It should also be noted that there are several unreferenced assumptions, and the report does not appear to have been independently peer reviewed.” (8)
Expert ‘opinion’
In the bottom left-hand corner of every page of the London Wood Burning Project report you can see the following disclaimer:
“This report is the independent expert opinion of the author(s)”
Firstly, anyone can claim to be an expert in whatever they like, however, the key word here is ‘opinion’.
Well, the SIA has commissioned extensive independent research which casts serious doubt on the estimations and ‘opinions’ provided by anti-woodburners (6). Experts question the methodologies and point out the lack of robust data used to support their dramatic claims.
We highly encourage you to read this report undertaken by Dr Amanda Lea-Langton, senior lecturer in Bioenergy Engineering at the University of Manchester:
-No scientific evidence found for adverse health impacts from exposure to the indoor air typically associated with modern, enclosed wood burning stoves
-No association shown between exposure to indoor wood burning and risk of asthma in developed countries
-Use of modern wood burning stoves may help to improve air quality inside the home due to the natural draught created during wood stove operation that pulls air from the room into the appliance and from outside
-Other sources of particulate matter in the home, such as cooking, can release much higher levels of PM compared to modern, enclosed wood burning stoves, and could therefore havegreater health risk potential
-In one study, oil-based cooking, such as frying food or grilling meat, had peak value PM concentrations significantly higher than the WHO recommended average 24hr exposure limit
-In the same study the Ecodesign wood burning stove indoor air quality averages during operation were below the WHO recommended limits
The official data (the truth) is good news!
And how about this for good news? The TRUTH is that UK PM 2.5 emissions have been steadily decreasing over the years despite record stove sales (please see the short video above). This is data taken directly from DEFRA and is a scientific and unbiased representation of the air quality in the UK. Whilst there is more we can all do, the evidence is resoundingly positive.
At the time of writing (11/01/2024) on a very cold winter’s day when wood stove usage would typically be higher, here is the PM2.5 picture for the UK taken, once again, from DEFRA’s official website.
So, when the anti-woodburners say 17% of emissions. It is 17% of a very low amount in the first place. Then, remember modern wood-burning stoves are just 1-2% of that low amount.
Modern stoves equal lower emissions with HUGE benefits
Next time you encounter someone who questions the benefits of modern wood-burning stoves, here is a list you can reel off!
1/ They can produce heat for sustained periods and are unaffected by external factors such as the weather.
2/ Allowing them to work in conjunction with wind, solar and other green heating solutions. A stove makes these great technologies more viable – They are not in competition with each other.
3/ A wood-burning stove is an ideal emergency/low-frequency heat source.
4/ Wood is a carbon-neutral fuel as it gives off the same amount of carbon whether it is burnt or decays naturally. The carbon released from burning wood is balanced out by the carbon absorbed by the tree during its lifetime.
5/ Wood fuel can be sourced locally without fracking and deep-sea oil drilling.
6/ A good quality stove can last many decades and provide an affordable source of heat for low-income households.
7/ The right to repair. The majority of components used within a Charnwood stove are modular and can be replaced when or if they wear out further extending the life of your stove.
8/ Charnwood stoves and packaging are fully recyclable.
The wood-burning stove community’s voice in this debate isn’t just about defending an industry; it’s about ensuring a fair and balanced path towards a cleaner and more energy-secure future. Targeting outdated appliances, promoting responsible practices, and encouraging sustainable forestry practices would yield far greater results for all.
Modern wood-burning stoves offer many benefits beyond warmth. They provide energy independence, encourage mental wellbeing, support rural communities, and help foster sustainable forestry practices. Responsible utilisation of modern wood-burning stoves can absolutely coexist with clean air initiatives, without compromising the environment.
We are passionate about building on our 50 years of experience leading developments in the industry and producing the most efficient stoves on the market. We understand why people want to reduce PM2.5 emissions even further and we support doing more to achieve this. That is precisely why we continue to invest significantly in technological advances rather than sensationalist marketing campaigns.
Thank you for reading and please share if this has resonated with you.
Now that the winter is in full swing, and the days are darker and colder, many of us are spending more time indoors.
And when the temperature drops, there’s nothing better than hibernating indoors, warm and snug in front of the stove. However, you must make sure that your stove is ready for the winter months.
We’ve created a helpful guide outlining how you can ensure that your stove is ready for winter.
Conduct a thorough stove examination
To make the most of your stove and maximise its longevity, it’s important that you conduct regular maintenance checks to ensure that your wood burning stove remains in sound working order, especially during the colder months of the year.
First and foremost, you should conduct a thorough examination, checking the below elements.
Clean out the ash pan
Most people begin their wood burning stove winter maintenance by emptying the ash pan. However, it’s important that you ensure that the stove is cold and remember, you should always wear protective gloves when cleaning your stove.
The ash pan can easily be cleaned out by using a small shovel to take the burnt ash from the bottom of the pan and dispose of it in a metal bucket. As a general rule of thumb, you should never keep warm ash indoors as it can cause a build-up of carbon monoxide. At the same time, all ash should be stored for at least 24 hours outside before it is disposed of.
Check all air holes are clear
Next, you should check that all air holes are clear and free from any debris buildup. After all, it’s not uncommon for dust, dirt and other elements to accumulate in your stove during Spring and Summer when it is not used as much or at all.
Clearing all air holes will ensure that a vital flow of oxygen can access your fire, optimising efficiency.
Check stove rope
Now you should take the time to check your stove rope, which can be found around the seals of your stove doors. If you do spot any sign of damage, when you are opening and shutting the door it should be addressed straight away, especially if you identify any gaps.
Remove any flammable objects
Before you start using your wood burning stove again, it’s important that you remove any
flammable objects from the area around your stove including decorations and combustibles such as plastic, wood-based products, carpet, textiles and upholstery. You will be amazed at how many flammable household items can end up next to your stove when it is not being used.
When the time comes to get your stove ready for Winter, you should also test your smoke and carbon monoxide alarms, as it is vital that these are in sound working order.
Start to bring in some seasoned wood into your property
Now it’s time to start stocking up on seasonal wood so that you are good to go! Remember to always store your wood in a dry space.

Charnwood is passionate about championing wood as a sustainable and eco-friendly fuel source. As the world transitions towards cleaner energy, wood continues to be a renewable, local, and efficient option that works perfectly in tandem with other renewable heat solutions.
Wood fuel has multiple benefits
Wood isn’t just great for generating heat; it also contributes to the health of our environment and the well-being of our communities. So, it is great news that, according to the Woodland Trust’s 2021 report, the UK’s woodland cover has more than doubled in the last 100 years, reaching 13.1% of the total land area. Forest coverage is set to continue increasing which provides a host of benefits, including:
Carbon Sequestration: Wood absorbs carbon dioxide from the atmosphere as it grows. When wood is burned responsibly, a closed-loop carbon cycle can be created with the carbon dioxide released being reabsorbed by new trees.
Biodiversity Enhancement: Woodlands are the habitat for a diverse range of wildlife, including many insects and birds. When done sustainably, harvesting wood encourages new growth and benefits biodiversity.
Local Jobs: Wood fuel production and distribution creates jobs and supports economies in rural areas. This is crucial for maintaining the vibrancy of local communities.
Harvesting & using wood sustainably
To ensure the long-term sustainability of wood as an energy source, it’s essential to adopt responsible practices including:
Silviculture: Silviculture encompasses the nurturing and management of woodlands. It’s the practice of controlling the growth, composition/structure, as well as quality of forests while supporting timber production. A wide spectrum of silvicultural systems exists, each tailored to specific woodland types and areas.
Practicing coppicing: a traditional method of harvesting trees by cutting branches and shoots, allowing them to regrow and provide a continuous supply of wood.
High-Efficiency Stoves: Using high-efficiency stoves that burn cleanly and efficiently, minimising emissions and maximising heat output.
Avoiding Freshly Felled Wood: Avoiding burning freshly felled ‘wet’ wood, as it produces higher emissions due to its high moisture content.
Why seasoned wood matters
Seasoned wood is wood that has been dried so that its moisture content is 20% or lower. This is crucial for several reasons:
Reduced Smoke Emissions: Seasoned wood burns with a cleaner flame, producing significantly lower levels of smoke and harmful pollutants.
Better Burning Efficiency: Dried wood ignites more easily and burns more evenly, ensuring maximum heat output and minimising waste.
Extended Stove Life: Burning seasoned wood helps to protect your wood stove from damage caused by excessive moisture and creosote buildup.
At Charnwood, we recommend using Woodsure wood. Woodsure is a UK-wide wood fuel certification scheme that ensures the wood you’re buying is sourced responsibly and is of the highest quality. Woodsure wood is always seasoned to the correct moisture content, ensuring you enjoy a clean, efficient, and eco-friendly heating experience.

Wood, when harvested and used responsibly, can play a significant role in a sustainable energy future. Charnwood are committed to creating a cleaner, greener future powered by renewable energy sources while preserving the natural beauty and wonders of our woodlands. Choosing your wood wisely and using best stove practices, you can be confident that you are contributing to a sustainable future while enjoying the warmth and comfort of a wood-burning stove.
When it comes to heating our homes, firewood is a popular choice. However, using wet or improperly seasoned firewood can lead to reduced efficiency, increased smoke and even potential chimney fires. This article will guide you through the process of checking firewood moisture content, understanding the ideal moisture levels, and recognising the importance of properly seasoned firewood for optimal burning.
Checking Firewood Moisture Content
What should the moisture level of logs be?
To achieve efficient and clean burning, firewood should be properly seasoned to reach an ideal moisture level. The optimal moisture content for firewood is generally considered to be around 15-20%. Anything above 20% is considered wet, while below 15% is considered overly dry.
How do you know if firewood is dry enough?
There are a few methods you can use to check how moist your firewood is.
Visual Inspection
Inspect the firewood for visible signs of moisture such as bark that is still attached, discolouration of the log, or a dull appearance. Wet wood tends to be heavier (because of the weight of the water) and may show signs of mould or fungi growth.
Sound Test
Tap two pieces of firewood together. If they produce a dull thud or a heavy sound, it indicates higher moisture content. Dry firewood will sound hollow and produce a sharper noise.
Moisture Meter
Investing in a moisture meter is an excellent way to accurately measure the moisture content of firewood. These devices use metal prongs to penetrate the wood and provide a digital readout of the moisture percentage. Because they provide a specific number, moisture meters are the most accurate method of determining firewood moisture content.
Why is firewood’s moisture level important?
Understanding the importance of firewood moisture levels is key to efficient and safe burning. Here are a few reasons why it matters:
Energy Efficiency
Wet firewood contains a significant amount of moisture, which requires extra energy to burn off. This energy is wasted as it is used to evaporate excess water rather than generate heat. Properly seasoned firewood with ideal moisture levels (15-20%) maximises energy efficiency.
Reduced Smoke and Pollution
Burning wet firewood produces more smoke, particulate matter and harmful pollutants. By using dry firewood, you can minimise smoke production and reduce environmental pollution.
Wet firewood can create excessive creosote build-up in the chimney, which increases the risk of chimney fires. Properly seasoned firewood has the right moisture content and thus reduces the likelihood of dangerous amounts of creosote building up in your chimney.
While it’s essential to avoid using wet firewood, excessively dry firewood can also pose challenges. Extremely dry firewood burns quickly and can lead to an overly hot fire that may damage your fireplace or wood stove and is likely to be uncomfortable for you and your family.
The best way to check if certain firewood is too dry is with a moisture meter as it will give you an easy-to-read percentage – anything less than 15% is too dry. In the rare event that your wood is too dry, mix it in with regular firewood to help raise the moisture content.

Wood-burning stoves are a popular way to heat homes because they offer an unparalleled source of comfort and warmth, however, it is important to be aware of carbon monoxide (CO) and the potential threats associated with its emissions.
Carbon monoxide is a colourless, odourless gas that can be very dangerous if inhaled in high concentrations. In this article, we will discuss the dangers of carbon monoxide, symptoms to look out for and, importantly, effective strategies for preventing carbon monoxide issues when using a wood-burning stove.
Why CO Is So Dangerous
Carbon monoxide is a dangerous gas because it binds to haemoglobin in the blood and reduces its ability to transport oxygen effectively. This can lead to oxygen deprivation and carbon monoxide poisoning. The gas can accumulate indoors and pose a severe threat, especially in poorly ventilated spaces. Even low levels of carbon monoxide exposure can result in long-term health issues.
Recognising the signs of carbon monoxide exposure is key for early detection and prevention of severe consequences.
Headaches and dizziness are common initial symptoms of carbon monoxide poisoning; exposure can also cause nausea and vomiting, often accompanied by a general feeling of being unwell.
Excessive tiredness, confusion, and difficulty concentrating are further signs of carbon monoxide poisoning. These symptoms can be particularly dangerous as they may impair judgment and hinder your ability to recognise the risk.
If you or anyone in your home experiences any of these symptoms while using your wood-burning stove, immediately ventilate the area and seek fresh air, and consult a medical professional.
How to Avoid Carbon Monoxide Problems
While the effects of carbon monoxide inhalation can be severe, it is thankfully easy to minimise the risk by following some simple precautions.
Clean Out Your Wood-Burning Stove
Regular maintenance is essential for the safe operation of your wood-burning stove. Cleaning the stove and its flue system helps prevent the build-up of creosote, a highly flammable substance that releases carbon monoxide and can lead to chimney fires.
Regularly remove ash (leaving about an inch in the base) and debris from the stove’s interior, including the firebox, grate, and ash pan. Use a metal scoop or shovel designed for this purpose. Dispose of the ashes in a metal container placed away from flammable materials.
It’s also important to have a clean chimney and flue. Schedule annual professional inspections and cleanings to remove creosote and other blockages from your chimney and flue system. A qualified technician will ensure that the flue is clear, reducing the risk of carbon monoxide build-up.
An annual inspection should include:
• Inspecting the flue for any cracks, leaks or damage that could result in the escape of carbon monoxide.
• Ensuring that there are no blockages or obstructions in the chimney, such as nests or debris. These can impede proper ventilation and increase the risk of carbon monoxide buildup.
• Assessing the combustion efficiency of your wood-burning stove. They will ensure that the stove is operating at its optimal level, minimising the production of carbon monoxide.
Provide Sufficient Ventilation
Proper ventilation is crucial to minimise the risk of carbon monoxide build-up. Ensure your stove is installed in a well-ventilated area, and that your home has adequate fresh air intake. Keep air vents unobstructed and consider installing a vent fan to improve air circulation.
Install Carbon Monoxide Alarms
Installing a carbon monoxide alarm is a crucial safety measure for any home with a wood-burning stove. These alarms can detect the presence of carbon monoxide gas and alert you to its presence, allowing for swift action.
Install a carbon monoxide alarm on each level of your home and near sleeping areas. Ensure they are mounted in accordance with the manufacturer’s instructions for placement, and test your carbon monoxide alarms regularly to ensure they are working properly.
Another important precaution to take is using only the correct fuel – this is paramount for safe wood-burning. Burn only seasoned hardwood that has been properly dried; it burns more efficiently, produces less smoke and reduces the risk of carbon monoxide emissions.
Do not burn treated or painted wood in your stove. These materials can release toxic chemicals when burned, including carbon monoxide.

Have you been using your wood-burning stove and are wondering if it is safe to keep burning overnight? Charnwood Stoves explains everything. Read below.
Wood burners and wood-burning stoves can significantly reduce a home’s heating bill making it an attractive alternative to electric, gas and oil heating for many homeowners.
Not only that, but research suggests that installing a log burner can even increase your home’s value by around five per cent. Additionally, a wood-burning stove can be used to heat not just the room it sits within, but the whole house.
For this reason, wood stoves and log burners have become immensely popular. The demand for wood-burning stoves has soared in recent years as households look for affordable ways to keep warm during freezing temperatures and an energy crisis.
Wood stoves can burn for hours providing homeowners with cost-effective and efficient heating solutions. However, many people with newly installed log burners and wood stoves wonder whether it is safe to leave their wood stoves burning at night.
This blog will mention everything you need to know about keeping your wood-burning stove on overnight.
Can You Leave Your Wood Stove On?
The safety of your home is of key importance. Leaving a burning fire unattended can be dangerous however, by following some key steps it is possible to keep your wood stove burning to warm your home at night.
Limit the Air Getting to the Fire
Once the flames have dampened down, it is important to close your stove’s air events to control and limit the air getting to the fire. Oxygen causes embers to increase in heat and strength causing the fire to burn faster. Charnwood stoves feature a simple, single air control that can be pushed in to slow the the burn to a slumber.
Check Your Space
The more space you have around your wood stove, the more effectively it will heat the room and the safer it will be. If there isn’t enough space around the stove for air and heat to circulate, the performance may be hindered.
What’s more, your wood stove burner must also be a suitable distance away from combustible materials, especially when left unattended at night. It is important never to stack logs close to the sides of your stove.
Maintain Your Chimney
If you have a wood stove, you need to have your chimney swept at least once a year to prevent the risk of a chimney fire. Soot and creosote will naturally collect in a chimney after using a wood-burning stove. If not regularly cleaned away, this can cause a chimney fire hazard. Regularly maintaining your chimney by having your chimney swept will allow the free passage of combustion gases to prevent carbon monoxide poisoning and chimney fires. Additionally, chimney sweeping will also remove foreign objects from your chimney such as bird nests, cobwebs, and other blockages.
Use the Right Wood
Using the right type of seasoned wood and stacking it correctly in your wood stove ensures the fire burns for much longer. Furthermore, continually burning improperly seasoned wood can cause a build-up of creosote deposits in the chimney. This not only affects the performance of the stove but can also lead to dangerous chimney fires.
Some types of wood, such as driftwood, are poisonous and release toxic chemicals into the air when burnt. This is another reason why you should always choose the right wood for your wood-burning stove carefully.

With the colder, darker months fast approaching, autumn is well and truly upon us.
And, with chunky knits, boots and jumpers already making an appearance, many people are thinking about how they’ll keep their homes warm and snug during the winter months.
Over recent years, wood burners have increased in popularity, with many people considering them to be an effective way to heat their homes for less during the ongoing energy crisis.
However, it’s important to remember that not all types of fuel are suitable for use in a wood burner. In fact, using the incorrect wood can increase maintenance costs, deliver poor stove performance, and even prove to be dangerous.
Types of wood to avoid
Within this guide, we’ll take a look at the types of wood you should avoid or burn with caution when using your wood burning stove.
Old pallets and treated timber
However tempting it may seem avoid burning pallets and treated timber. Paint, varnishes and oils can give off harmful emissions and can damage your stove and chimney.
Pine
Because pine has a high resin content, it is not considered the best wood to burn on a log burner. It burns quickly and the resin can seep out and clog up different parts of the stove system, which can lead to a whole host of operational problems. If you do choose to burn pine ensure it is well seasoned.
Larch
Much like Pine, Larch contains high levels of resin, which forms sticky deposits inside of the stove and flue.
Poplar
Poplar doesn’t burn for long periods of time and, when it does burn it can be smoky. As a result, it isn’t a good choice for a wood burner.
Laburnum
Laburnum is poisonous when used as firewood so should not be used as fuel for a log burner.
Alder
Alder produces a relatively low heat output, and is renowned for popping and sparking as it burns. This type of wood burns quickly but produces very little heat.
Chestnut
Most varieties of chestnut are okay to burn on a log burner, however, you should be aware that they tend to spit and spark, meaning many people are reluctant to use them.
Cypress
Cypress isn’t ideal as your main firewood source as it provides a low heat output and doesn’t produce very good coals.
Spruce
Spruce produces little heat making it an ineffective fuel for a log-burning stove.
Willow
Firewood should contain a moisture content of below 20%. Willow tends to grow in wet soils or beside water bodies, giving it a high moisture content so if you choose to burn it ensure it is dry and well seasoned.
Although there are many types of wood that shouldn’t be used on a wood burner, there are also many that you can use for fuel, including:
Hardwood firewood
Hardwoods, including ash, birch, maple, oak, and the majority of fruit trees, are some of the best fuels for wood burning stoves due to the fact that they can burn for long periods of time while generating plenty of heat. Hardwood is also cleaner to handle than other types of wood.
Softwood firewood
Some softwoods tend to be cheaper than hardwoods and can also be used in your wood burning stove.
