We have been eagerly anticipating the updated figures for PM 2.5 emissions from ‘domestic burning’ as we knew this should go a long way to settling the debate that has been raging on socials and in the wider media this winter. The reason all eyes are on this data is because it reflects a period of emissions that coincided with record stove sales. Therefore, if anti-wood-burning campaigners were right then a significant increase in PM2.5 should, logically, be observed. However, as reported by the SIA, Defra have finally released their figures and it is official: PM2.5 from domestic burning has DECREASED despite record wood-burning stove sales over the same period.
The release of the latest air pollution data by Defra shows an 18% reduction in PM2.5 emissions nationally between 2012 and 2022.
Particulate emissions from “domestic combustion” fell between 2021 and 2022 with a 3.9% reduction in PM10 and a 4% reduction in PM2.5 from “domestic combustion”. The latest data also shows that PM2.5 emissions from the domestic use of wood fuel specifically fell by 2.7%.
Chair of the SIA, Andy Hill, commented:
“SIA members reported annual sales of over 200k units in 2022, a 40% increase on 2021. This increase was driven by several factors including spiralling energy prices and increasing consumer apprehension regarding grid reliability. What is clear from the latest data is that, despite an increase in stove sales, domestic emissions have come down. This points clearly and conclusively to the improvement in air quality that can be achieved by replacing open fires and older stove models with modern, Ecodesign design compliant stoves such as clearSkies certified appliances.”
“The SIA looks forward to being able to apportion the numbers more accurately once the NAEI publishes the detailed source and activity name data that drives the top-level figures released by Defra. Last year this clearly showed that PM2.5 emissions from Ecodesign stoves burning dry wood fuel accounted for less than 0.1% of the UK total.”
_________
We are delighted this data finally confirms what we have been trying to communicate about the benefits offered by modern wood burning stoves. But rest assured, it is our full intention to go even further in reducing emissions. Through further investment and technological advances and extending our hand to those across the aisle to collaborate.
In one of our most recent blogs, we called upon those seeking to ban wood-burning to open constructive dialogue so that we can potentially work together to make even greater progress reducing emissions. The data is conclusive, and it’s time to come together and focus on the pragmatic changes that will move the needle further in the right direction.
Over the last few weeks there has been a lot of talk on wood burning centered around ‘No Burn Night’.
As a stove manufacturer we certainly have a vested interest and have been pushing back on claims which we have felt to be unfair, misleading or untrue. Much of this debate has spilt over onto social media where it has often been less than savoury! Of course, we all know that social media is never the best place to have these in-depth discussions.
Often in debates we tend to try and demonise our opposition, we try to (mis)represent their arguments on our terms, often to discredit their motives, and aim to crush them and be the victors of the argument. We saw this during the Brexit debate, on both sides, – issues were simplified, positions were demonised, mistruths were told, and it is probably fair to say from whatever perspective you come from, that the results have been a bit of a disaster. When it comes to the debate on air quality it is too important to allow this to happen. So, what if we take a different approach? What if we tried to believe the best in each other and the motivations behind what we are all trying to achieve?!
There is a risk here – surely if we try and understand the other side, give them the benefit of the doubt even, won’t they take advantage and undermine our position further? Surely, the first rule of negotiation is to go in hard and then maybe meet in the middle. Well maybe, but what if we try to do things differently? Indeed, the prize is surely one worth having as this debate centers around an important issue: the environment and more specifically air quality. Something that we all believe is vitally important.
What are the arguments on both sides?
One of the first Charnwood stoves replacing a more polluting open fire
In writing this, we are aware that we approach this from a position of vested interest, so let’s start with us. We manufacture, amongst other things, wood burning stoves and have done so for around 50 years. We employ around 180 people here on the Isle of Wight and export to around 20 countries. We are a family business and work with other small, often family-run businesses up and down the country who sell and install our stoves. We started making stoves because there was an oil crisis and at the end of the 1970s, Dutch Elm disease had killed many trees. This wood was often burnt on open fires, which was neither efficient or clean. That inspired the founders to start making stoves to burn the wood better. Over the years we have found ways to dramatically improve performance, so we get more heat and less smoke from the wood we burn.
But why burn wood at all?
Well, wood is a plentiful natural and renewable resource that reduces our reliance on fossil fuels. It has been used for heating and other things for millennia. Forest management is also vitally important – well-managed woodland is good for biodiversity and is lost if it is not managed well. We also see forest fires tragically result from not managing forests, such as those in California.
Energy has, throughout history, been the key to power – the British empire was built on coal. Then came oil and we saw the rise of America, Russia and the Middle East. As we move into a low carbon economy, we see access to rare earth metals that make batteries as critical, and it is China who have taken the lead in this race. Those who control access to energy hold power. But wood is different and it’s plentiful which means it cannot be controlled by any large player.
In this image a modern ultra-efficient Charnwood Island Stove has replaced an open fire
So, clearly, we think wood has many advantages. “Of course you do”, you might say! But we are also aware that to heat from wood it needs to be burnt, and burning things creates smoke. In the UK, traditionally it has been open fires which have been the primary method of heating, and it has always been our argument that burning on a stove is far better – more efficient and with significantly less emissions (3). Over the years we have continued to invest in equipment to keep improving even further.
SO, what is the problem with wood?
If we look at those that don’t like wood burning we hear a very different story. It is perhaps unfair of us to try and explain the opposite position, but notwithstanding our obvious bias, we will try and Steel Man their position: Wood when burnt produces, amongst other things PM2.5 – these are small particles that are not good for us and when breathed it can cause health problems. These health problems are hotly debated as the body will deal with a certain amount of PM2.5 (and different types) but it is claimed that it can cause respiratory disease, and even dementia. In fact, all types of burning will produce these particles to greater and lesser extents. The term PM2.5 describes the size of the particle rather than the composition, and its composition depends on what is being burnt. More research is needed to understand the relative toxicity of the different types of particles. If we take the position that there is no safe level of PM2.5 then logically it must follow that we should not burn things – and wood is included in this.
What do anti-wood burners think of pro wood burners
Again, this is difficult to answer and there are many views. But it is probably fair to say that they think we are an industry with vested interests whose desire to make money overrides the damage we do to the environment and air quality. Of course on a local and personal level if you are living next to someone who is creating a lot of smoke by burning wood badly, maybe on an open fire, old appliance, using bad wood or even unregulated burning outside it is really not pleasant and rightly this should be stopped.
What do pro-wood burning people think of anti-wood burners
It is easier for us to answer this one! We often feel misrepresented and frustrated by the lack of distinction between different types of wood burning. Wood burnt on a stove will generally be much cleaner than that of wood burnt on an open fire or outdoor appliance. 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)
We can often also feel aggrieved because for us (and some other stove companies) the reason we got into making stoves was to improve air quality and the environment. So, we feel as if we are being shoved out of our own party! We want to improve air quality by better burning, and we feel through misrepresentation we are frustrated in this mission. We strongly believe that we are at risk of seeing air quality worsen by not getting people to burn better.
Ecodesign-compliant stoves are up to 90% more efficient than an open fire and in London 70% of wood burning still occurs on open fires. (1) 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. In fact, the latest wood-burning figures released by Defra appear to show this taking place across the country as reported by the SIA:
“What is clear from the latest data is that, despite an increase in stove sales, domestic emissions have come down. This points clearly and conclusively to the improvement in air quality that can be achieved by replacing open fires and older stove models with modern, Ecodesign design compliant stoves such as clearSkies certified appliances.” (4)
Finally, it must be said that on some fringes of our community, there is also a feeling that we are up against bigger powers (in much the same way that those who don’t like wood burning feel we have large commercial interests). We are in fact quite a small industry made up of a lot of small and medium-sized companies. There is often a feeling that the anti woodburning lobby is being funded by big players (perhaps fossil fuel companies) who have a vested interest in having control over energy. There is also a subset who feels that governments don’t like wood burning because they cannot tax it!
Believe the best
So, there is distrust on both sides – and although there may be good reason for some of it, we share the same motivation: we both want to improve air quality and the environment. Of course, we are taking different approaches towards this. Some want to ban burning, while in our company we want to improve it. But we mustn’t forget, during these debates, that our goal is the same – cleaner air!
Can we work together?
If we share the same goal can we help each other? Is the pragmatic approach mutually exclusive to the idealistic one? Is the idealistic path really threatened by the pragmatic one? Can we work together?
Could we think of it as more of a relay race where the goal is clean air? To get there we all need to work together to get the biggest improvements first and then keep improving. For our industry it means using technology to keep improving stoves, it means working constructively with legislators to implement meaningful and challenging standards which are enforceable and actually make a difference. We need to be really honest about where this is not happening and be prepared to take tough decisions. For those whose goal is to see all burning banned it might mean first putting their efforts into stopping the worst kind of burning – unregulated indoor and outdoor burning. Difficult conversations need to be had; goodwill needs to be shown on both sides, we may not agree on everything but we share the same goal and we can support each other in those things we do agree on. The prize is worth it, so let’s choose to believe the best in each other and together make a difference!

Further reading that explains in more detail why we strongly feel a collaborative approach is required:
The SIA have written a fantastic blog to address the anti-woodburner’s misleading, ambiguous and, in some cases, untrue media campaign. It was released in time for Clean Air Night to give consumers a chance to get both sides of the story. Here we will share the key information as we want to amplify their important voice in this ongoing debate.
The claims made here by the London Wood Burning Project (above left) and cleanairhub.org.uk (above right) rely on the grouping of all methods of burning wood (including garden bonfires & firepits) at home. However, the data from the National Atmospheric Emissions Inventory (NAEI) shows us that burning dry wood on an Ecodesign compliant stove accounted for less than 0.1% of total UK PM2.5 emissions in 2021.
Modern stoves offer a range of benefits and you can get both sides of the story and learn more about that here.
Just like the posts above, the term ‘wood burning’ in this post (below) is deliberately ambiguous and takes no account of the type of appliance or quality of the wood fuel.
There is reliable evidence that using dry wood and other sustainable solid fuels can help consumers reduce their home heating bills. A recent study by Gemserve for Homefire found that households with gas central heating that adopt zonal heating using dry wood fuel could save up to 7% on their annual heating bill and up to 11% using smokeless solid fuel in the same way.
The same study also found that using renewable, sustainably sourced wood fuel instead of fossil fuel gas results in typical carbon savings of over half a tonne of CO2e / year.
The claim (above) that a wood burning stove is six times more polluting than an HGV is hugely misleading.
The claim is based on a report by the European Environmental Bureau published in 2022 that looks at the amount of emissions given off by generating a GJ of heat in a stove compared to the emissions releases generating a GJ of power in an HGV.
The claims made by the study rely on a simplistic calculation using permitted rates of emission. The study also fails to factor in the non-exhaust emissions of the HGV.
What we end up with is an apples and oranges comparison that fails to consider the impact of real-world use. According to a 2020 Defra report, on average stove users light their stoves for between 3.7 and 4.5 hours a day during the winter months. An HGV can be driven by the same driver for up to 9 hours per day, and the vehicle potentially operates 24/7 up to 365 days a year.
This means that over the course of 1 week’s real-world use a Euro 6 HGV actually produces 13 times more PM2.5 (271g) than an Ecodesign stove (20.16g). You can read more on this comparison here.
This claim (above) by campaign group Mums for Lungs is ambiguous and relies on the reader not seeking any further information on the data.
The data from the National Atmospheric Emissions Inventory (NAEI) which breaks down UK PM2.5 emissions by activity and source, shows us that in 2021 cigarette smoking accounted for 12 times more PM2.5 in the UK than burning dry wood on an Ecodesign compliant stove did.
Some of the adverts by the cleanairhub.org.uk, part of Global Action Plan, in support of Clean Air Night even contain false claims (see below).
This is one example. Contrary to the information given in this post, wood logs have the lowest carbon emission factor of any domestic heating fuel at 0.01kg CO2e per kWh. That’s 1/20th the carbon emissions of natural gas or electricity, and 1/29th that of oil.
Burning dry wood is a modern, Ecodesign compliant stove is a low carbon way to heat you home and can play a key role in helping the UK to meet its net zero objectives.
You can find out more about the benefits of choosing modern stoves here.
This statement (above) is false. Woodland management is needed to ensure healthy forests and the ecosystems they support.
Wood fuel is a key component of the woodland management cycle and the economies attached to it. Using wood as fuel also plays a vital role in maintaining woodland diversity, health, and resilience. Locally sourced wood fuel helps support small businesses and reduces the carbon footprint of fuel transport.
You can learn more about the importance of woodland management here
This is another misleading statement (above) and one which is actually disproved by the findings of a recent Imperial College study which found that a “clearSkies Level 5 stove demonstrated some benefits for indoor air quality” and that “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…”.
A literature review by commissioned by the SIA and carried out by the University of Manchester found no scientific evidence for adverse health impacts from exposure to the indoor air typically associated with modern, enclosed wood burning stoves.
And lastly for something positive. We could not agree more with this post and there are significant reductions (up to 90%) possible in the emissions created by domestic burning by switching from open fires and older stoves to modern, Ecodesign compliant stoves.
The SIA encourages all solid fuel stove users to educate themselves on the importance of:
Using the right appliance – if you use an open fire or an older stove it is time to upgrade. A modern Ecodesign compliant stove releases up to 90% less emissions than an open fire and up to 80% less than many older stoves.
Ensuring your stove is fitted by an appropriately qualified competent person e.g. HETAS or OFTEC registered.
Always use good quality fuel. Look for the Ready to Burn logo and never use chemically treated wood or burn waste on your stove.
Get your stove serviced and your chimney swept at least once a year. We recommend NVQ qualified sweeps for this.
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.

We were delighted to receive such an incredible response from our engaged wood-stove community. From discovering the most popular stove accessory to users’ other must-haves and how easy people find them to use – many interesting and useful insights were gained!
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.

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.
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.
We’re proud to present the Cranmore: a classic new wood burning stove from Charnwood. While it may be traditional in style it uses the very latest in clean burn technology. The Cranmore draws inspiration from the Regency era with a single framed glass door and archetypal detailing. The stoves pleasing proportions make it well suited to a traditional fireplace and with its large picture window and mesmerising flame pattern it is an ideal replacement for an open fire.
The best of British
The Cranmore is British made with British materials, using the latest technology that draws on Charnwood’s 50 years of expertise. It is available in a range of colours and features a firm close, cool-to-touch, handle for safe and easy reloading. It is incredibly simple to operate with one single air control and features a sliding firebed for clean and easy ash removal.
Available as 5 or 7kW models, the Cranmore uses our clean-burn BLU technology and is exceptionally efficient, with a level 5 clearSkies rating. The comparison table below is a useful tool; however we recommend speaking with your Charnwood supplierto help you decide which stove is most suited to your space.
&nsbp;
The perfect open fire replacement
With rules around Eco Design Ready stoves coming into force in 2022 and the potential for further regulation, the Cranmore is an ideal and timely choice. It offers the wonderful ambience and flame picture associated with open fires, while exceeding all minimum criteria for Eco Design Ready status.
The difference between an open fire and the Cranmore in terms of its efficiency and eco-credentials shouldn’t be understated. The Cranmore produces a far more efficient burn and reduces PM emissions by 90%. Added to Charnwood’s policy of caring for the environment, in all aspects of the business, means a Cranmore stove is an environmentally sound heating solution you can be proud of.

In the ongoing debate over air quality and PM2.5 emissions, modern wood-burning stoves often face unfair criticism. The root of the issue lies in the unfortunate lumping together of modern ultra-efficient stoves with their vastly more polluting counterparts—open fires, outdoor bonfires and old, poorly maintained stoves. Today, we turn our attention to the latest report, released by the Environmental Research Group.
Anti-woodburning groups have previously drawn on questionable data often not recognising the crucial distinctions between various types of wood-burning. However, there is a glimmer of progress, as this latest report at least acknowledges some of the benefits of ultra-efficient stoves and that ClearSkies 5 Stoves can in fact improve indoor and outdoor air quality. This is a step in the right direction.
Key Findings from the London Wood-Burning Project:
On page 71 of the 127-page report, we find the page titled Key Findings. Below are the 4 crucial pieces of information from this page:
1/ Use of the clearSkies Level5 stove 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 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.
Again, we have tried to communicate this fact for a long time, as it 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.
4/ The PM2.5 increase measured outdoors, due to the non-DEFRA exempt stove, was double the increase due to the clearSkies Level 5 stove. 50 μg m-3 and approx. 25 μg m-3
The methodology used to gather this data from the environment, again, can not adequately separate the different sources of PM2.5 in the tested areas. It is subject to error from many environmental factors, such as road traffic, construction, manufacturing, and other industrial processes.
However, this data does still accept that a modern ClearSkies 5 stove significantly reduces emissions. We have rigorously tested all Charnwood stoves and when ensuring best stove practices and using seasoned wood with a moisture content of less than 20%, emissions can be reduced by up to 90% in comparison with an open fire. This provides an exceptionally clean burn!
Differentiating Wood-Burning Practices:
It is essential to differentiate between various forms of wood-burning. The UK government’s 2020 figures highlight that Ecodesign-compliant stoves contribute only 1-2% to PM2.5 emissions, a fraction compared to other sources. ClearSkies Level 5 stoves, surpass Ecodesign standards, offering a further reduction in emissions by up to 30%!
This is where the anti-wood-burning stove movement has gotten it so wrong in the past. By not differentiating accurately between different wood-burning practices they have missed the opportunity to really help reduce PM 2.5 emissions with a solution that has been proven to work – modern ultra-efficient stoves.
In London 70% of wood burning still occurs on open fires. 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. The emissions of 70% of London Wood burning could be reduced by 90%!
Wood-Burning Stove’s Co-Heating Future
Heat pumps, solar and wind energy, have positive qualities, but are simply not sufficient to meet our home heating needs on their own. This is particularly true for the vast amount of older housing stock across the UK. Wood-burning stoves can increase the uptake of other renewables by providing energy security and filling the gaps in power.
Below is a link to an article which comprehensively explains why modern wood-burning stoves will be an essential heating solution long into the future.
With gas and electricity prices set to increase even further in January 2024, we need all sides of the debate to work towards a more informed and positive dialogue. For our part, we continue to lead the industry in creating the most efficient stoves on the market. We are investing heavily to continually improve and are passionate about providing people with energy security and the many other benefits offered by wood-burning stoves.
The Stove Industry Alliance (SIA) has carefully examined a recent study by Global Action Plan/Impact on Urban Health, titled “Relight my fire? Investigating the true cost of wood-burning stoves.” In this blog, we will present some of the key insights and considerations revealed by the SIA that address the misleading conclusions made.
Study Methodology Critique
The SIA raises important questions regarding the methodology used in the study. Specifically, the model scenarios seem to artificially inflate the costs associated with wood-burning stoves while decreasing costs related to Air Source Heat Pumps (ASHP). The SIA points out discrepancies in cost consideration, installation assumptions, and the efficiency impact of heating system distribution.
Here are just two of the key points raised which show why it is impossible to draw accurate conclusions from the data set:
Model B “includes the cost of purchasing the item (stove) and installation,while all options include maintenance and replacement costs.” The SIA questions whythe purchase and installation costs have been factored in for the stove led heating inModel B, as they have not been factored in for the gas boiler led heating, Model A?
Model E “Newly installed Air Source Heat Pump (ASHP) providing 100% of heat” underestimates the actual running costs of the ASHP in the reference dwelling used (a Victorian mid-terrace of single skin, uninsulated solid brick construction).Heat pumps are not suitable for use in badly insulated housing stock; they will not run optimally in these conditions and therefore won’t give a 3.5 seasonal CoP which thereport uses to reach its conclusions.
Appliance Efficiency
When evaluating cost-effectiveness, appliance efficiency is a highly significant variable, and is not accurately reflected in the study. Since January 1, 2022, all solid fuel stoves have had to adhere to Ecodesign Regulations and ensure a minimum efficiency of 75%. Many of our stoves surpass this requirement, with tested efficiencies exceeding well beyond 80%, which is comparable to the most efficient gas room heaters in peak condition. It is also important to consider that wood-stoves offer individuals better localised space heating, meaning they allow you to heat the space you need without wasting heat on empty rooms. This is a key part of many people’s heating strategy and this flexibility also facilitates off-grid low-carbon sustainable living.
Comparative Fuel Costs
The SIA references data from various sources, including Nottingham Energy Partnership, to provide readers with a comprehensive view of comparative costs per kWh for different heating fuels. As of October 2023, the price per kWh for an ASHP is 12.37p, kiln-dried logs at 11.18p, mains gas at 8.64p, and electricity at 33.40p. It should be noted that, between November 2022 and June 2023, kiln-dried wood logs were more cost-effective than mains gas per kWh.
This points to another key reason people choose wood-burning stoves – energy security. It is still fresh in everyone’s minds how susceptible gas and electricity prices are to spiking at a moment’s notice because of global issues. Sustainable sources of wood are available locally and provide a vital shield against the next crisis.
There are many factors that determine which heating solution is best for your home. As pointed out by the SIA, this latest study has missed many factors that favour wood-burning stoves, particularly as part of a modern co-heating solution.
Charnwood Stoves remains committed to leading the industry in producing the most reliable, efficient, and sustainable wood-burning stoves on the market. We continue to invest heavily in research and development to improve efficiencies even further and have many exciting developments on the way!
