Wood-burning stoves have continued to grow in popularity as they offer a host of benefits that other heating solutions can’t provide. They are a true focal point in a home, encouraging those life affirming moments where friends and family gather together to share quality time. However, where sustainability and emissions targets are now in the forefront of minds, some sections of the media are asking if wood-burning stoves are still a good choice? The simple answer is a resounding yes! Modern wood-burning stoves are ultra-efficient and more sustainable than ever and shouldn’t be confused with other forms of wood-burning such as open fires, bonfires and old stoves.
Read on to find out how modern wood-burning stoves are evolving and why they will play an important role in our home heating future!
So, what are the current wood-burning stove regulations?
Many towns and cities in the UK, have been designated as ‘smoke control areas’ by the government with a number of rules introduced:
1/ You cannot release smoke from a chimney
2/ You must only burn authorised fuel, unless you use an appliance approved by DEFRA (also known as an ‘exempt appliance’ or ‘DEFRA exempt appliance’)
The good news is by choosing a DEFRA-exempt stove, such as a Charnwood stove, you can still enjoy a wood fire and the benefits of wood-burning while adhering to strict emission standards.
Smoke control areas cover most towns and cities in England, Scotland, Northern Ireland, and parts of Wales. We recommend checking with your local council to see if these regulations apply to you. If you don’t live in a smoke control area, these restrictions won’t affect you.
DEFRA-exempt stoves
If you live in a smoke control area you have two options:
1/Use a DEFRA-exempt stove: These stoves use the latest wood-burning technology to minimise smoke emissions and allow you to continue to burn dry wood.
DEFRA, which stands for the Department for Environment, Food & Rural Affairs, uses a special independent testing house that tests and approves stoves for use in smoke control areas. If you’re looking to burn wood in these areas, it’s crucial to have a DEFRA-exempt stove or you could receive a fine.
Fuel types
It’s now illegal to burn coal (with the exception of smokeless coal like anthracite) or wet wood in your home (any wood with a moisture content above 20%). The focus is on encouraging using cleaner fuels that produce less smoke and are better for the environment and your health.
You can burn the following fuels in your stove:
Kiln-dried logs
-Wood dried in a kiln with a moisture content below 20%. Look for the Ready-To Burn Label.
-Your own wood that has been seasoned properly. We recommend using a moisture meter to check it is ready to use (moisture levels below 20%).
Smokeless fuels
As discussed above, these include fuels such as anthracite, semi-anthracite, gas and low volatile steam coal. Check here.
If you live in a smoke control area, remember that you can only burn logs (dry wood with a 20% mositure level or less) if you have a DEFRA-exempt stove.
Leading the way with Ecodesign & Clearskies stoves
The introduction of Ecodesign regulations has marked a new era for wood-burning stoves. Since 2022, all new stoves have had to meet stringent standards for emissions and efficiency (an efficiency rating of at least 75%). Charnwood is at the forefront of this movement, offering stoves that not only comply with but outperform these regulations. Our Clearskies 5 rated stoves are up to 89% efficient – that is an exceptionally cleaner and more efficient burn!

Whilst concerns with modern wood-burning stoves are misguided and the result of not accurately interpreting the data, it is still certainly worth using the most efficient stoves on the market to be as sustainable as possible and save money on wood fuel.
This blog will look at some of our most efficient wood-burning stoves, and a very exciting development in technology!
What is wood-burning stove “efficiency”?
Wood-burning stove efficiency refers to how effectively the stove burns wood fuel to heat your home. Typically, this is measured as a percentage, where higher percentages indicate better performance. Used correctly, a more efficient stove will produce more heat with less wood, reducing both fuel costs and emissions. If a stove has 80% efficiency, it means only 20% of the potential heat from the fuel is lost in the combustion process.
How to choose the most efficient and suitable wood-burning stove?
Finding the most suitable and efficient wood-burning stove for your home means considering several factors:
Energy efficiency rating
The easiest way to determine efficiency is to check the stove’s energy efficiency rating. This rating is shown as a percentage and indicates how efficiently the stove converts fuel into heat. It should be clearly marked on the stove and if not, be sure to ask the dealer for more info. We suggest looking for stoves with high energy efficiency ratings as these will offer you the best possible performance.
With the introduction of Ecodesign regulations all stoves must have an efficiency rating of at least 75%. This is significant progress, however here at Charnwood we have worked hard to make sure that all our stoves significantly outperform this efficiency rating. Our Clearskies 5 rated stoves are up to 89% efficient – that is an exceptionally clean and efficient burn!
Heat output
Another key consideration is choosing a stove size that is appropriate for your space. A stove that is too large will waste fuel, while one that is too small may struggle to heat the room enough. It’s important to consider the heat output of your stove, measured in kilowatts (kW) and match it to the size and insulation of your space – you can use our handy Stove Calculator toolto find the level of output you’d need to effectively heat your room or you can speak to your local Charnwood dealer for help.
Customer reviews and recommendations
Researching customer reviews and recommendations can provide valuable insights into the real-life performance and efficiency of different wood-burning stoves.
We recommend choosing a stove that combines high efficiency, eco-friendly credentials and stylish design. Our range of DEFRA-approved stoves, including the popular Aire, Arc and Cove models, offer excellent efficiency ratings and low emissions. With innovative features such as Cleanburn technology and a cool-to-touch handle, Charnwood stoves provide both warmth and peace of mind.
Ultimately we recommend you speak to an official Charnwood dealer for guidance on what will best suit your space and other requirements.

Using a wood-burning stove is a very safe, sustainable and cost-effective way to heat your home and create a warm and cosy ambience. It is, however, important to consider the type and condition of the wood you burn as this can significantly impact the positive benefits of your fire. One important aspect to consider is whether the wood is sufficiently dry enough or is it still too damp to burn and does it require more seasoning (drying).
Why is burning damp wood in your home a problem?
More smoke and condensation can cause residue buildup
When you burn damp or wet wood, it produces much more smoke that condenses onto the cooler sides of the flue or chimney. This can lead to creosote residue build-up which is highly flammable and increases the risk of chimney fires and damage to your stove and flue.
Damp wood results in poor-quality fires
Damp wood, which is wood with a moisture level of over 20%, doesn’t burn efficiently. The high moisture content prevents the wood from reaching the high temperatures needed for adequate combustion. As a result, the fire will produce far more smoke and significantly less heat which is highly inefficient. The excess smoke and particulates can also contribute to indoor and outdoor air pollution which is something we can all agree we want to minimise.
The good news:A Charnwood Clearskies 5 rated stove using well-seasoned or kiln-dried wood drastically reduces any emissions and maximises fuel efficiency – ultra-clean burning that saves you money on your fuel bill!
The excessive smoke and soot produced by burning damp wood can lead to an increased accumulation of residue on the stove glass. This can be a real pain to clean and there is also a risk of scratching the glass surface in the process if you’re not careful. As well as stopping you from being able to fully enjoy the aesthetic appeal of your stove, it can also impede your ability to monitor and respond to the fire and ensure it is burning optimally.
Burning damp wood is much less efficient which means you end up burning more wood for less heat. That means more trees are required and more expensive fuel bills.
The lower combustion rate of wet wood produces more pollutants than that of dry wood releasing higher levels of particulate matter (PM10 and PM2.5) carbon monoxide and volatile organic compounds (VOCs) into the atmosphere.
More good news: By burning dry wood with a modern stove, you can reduce your carbon footprint and significantly minimise the environmental impact of your fires. It is important to remember that burning dry wood on an Ecodesign-compliant stove accounts for less than 0.3% of total UK PM2.5 emissions – so be mindful of what you read in the media!
Beyond an extreme situation where there are no other options, the short answer is no. The safety issues, inefficiency, potential damage to your stove and the environmental impacts far outweigh any potential convenience. It’s always better to allow your wood to season thoroughly before burning or you can purchase kiln-dried wood which is readily available – remember to look for the Ready To Burn logo!
Properly seasoned wood will have a moisture content of less than 20%, which you can check with a moisture meter. This will ensure a cleaner, hotter and safer fire to enjoy.
Charnwood has been manufacturing the highest quality British made wood-burning stoves since 1972. So, if you have any questions about heating your home with a wood-burning stove, please get in touch and our experienced team will be happy to help.
As previously reported, the latest data from the National Atmospheric Emissions Inventory (NAEI), supports the fact that modern wood-burning stoves are safe, environmentally responsible and cost-effective. In the SIA’s recent blog, they look closely at the details to see what more can be learnt.
The facts about wood-burning stoves and PM2.5 emissions
One of the main concerns about wood-burning stoves is their impact on air quality, specifically regarding PM2.5 emissions. However, the main cause of concern is that certain media outlets continue to report in a reductive way and lump in the emissions of modern wood-burning stoves with those of old stoves, open fires and bonfires. They add all the emissions together and present an inflated figure which unfortunately misleads people.
However, when we take the time to examine the detailed NAEI data, we start to see huge differences between the different forms of domestic combustion:
“there was a huge difference between the PM2.5 emissions produced by an open fire compared to an Ecodesign closed stove in 2022; the former being responsible for 13.3% of total UK PM2.5 emissions, while the latter accounts for just 1.8%.1
Secondly, we can see that the type of fuel we choose to burn has a significant impact on our emissions. When looking at wood fuel only, open fires account for 9.8% of total UK PM2.5 emissions and Ecodesign stoves a much lower 1.4%.2
Furthermore, the data also shows the impact that dry wood fuel has on reducing emissions, bringing the figures above down to 1.8% of total UK PM2.5 from open fires and just 0.3% from Ecodesign compliant stove models.3
It is clear to see that when choosing a modern, Ecodesign stove and only burning dry (at or below 20% moisture content) wood fuel, PM2.5 emissions are minimal.”
For further context, the NAEI data also shows us that:
-Burning dry wood on an Ecodesign-compliant stove accounts for less than 0.3% of total UK PM2.5 emissions.
-Road transport PM2.5 emissions are 66.7 times higher than those from Ecodesign stoves burning dry wood.
-Cigarette smoking causes 4.7 times more PM2.5 emissions than Ecodesign stoves burning dry wood.
-Bonfire night generates 7.4 times more PM2.5 emissions in a single night than all Ecodesign stoves burning dry wood do in an entire year.
The data is clear, modern wood-burning stoves burning dry wood have a very minimal impact on air quality especially when compared to other common sources of pollution.
Ecodesign regulations
Since January 1, 2022, all new solid fuel stoves have had to adhere to Ecodesign Regulations, which ensures higher efficiencies and lower emissions. At Charnwood Stoves, we are proud to offer products that not only meet but often improve upon these standards. Our stoves are designed to burn wood more completely, which means less smoke, significantly fewer particulates, and more heat from less fuel.
An Ecodesign-compliant stove used correctly will emit up to 90% less emissions than an open fire and up to 80% less than many older stove models. This makes modern wood-burning stoves a very sustainable choice for heating your home.
The economic and environmental benefits of wood-burning stoves
In addition to their low emissions, modern wood-burning stoves offer several other benefits:
Cost-effective heating
The Nottingham Energy Partnership’s July 2024 data states that the price per kWh of kiln-dried logs is now 10.53p (down from 11.18p), making it significantly cheaper than electricity (28.58p per kWh) and comparable to mains gas (7.01p per kWh). This cost efficiency was particularly notable between November 2022 and June 2023 when kiln-dried wood logs were more affordable than mains gas per kWh.
Energy independence
Wood-burning stoves can provide low-carbon heat that is perfect for living off-grid. This is particularly valuable in remote areas where gas and electricity supply may be unreliable or expensive. It also offers protection from the volatile price of mains energy we have witnessed in recent years.
Sustainability
Using sustainably sourced wood reduces dependence on fossil fuels and supports local forestry management practices. Look for the Ready to Burn logo to ensure your wood logs have a moisture content at or below 20%, which is crucial for efficient and clean burning. Learn more here
Well-being
We conducted a survey of stove users to better understand the significant and unique benefits that wood-burning stoves provide their owners and family’s wellbeing. The response was phenomenal with 1227 users providing deep insight into the wider benefits of owning and using a stove.
93% replied, definitively, that their stove has a positive impact on their wellbeing. Learn more here
Our top tips to ensure safety and top performance
To maximise the benefits of your wood-burning stove, proper installation, using the right wood and maintenance are essential. Here are some key recommendations:
Professional installation
Ensure your stove is fitted by a qualified professional, such as those registered with HETAS or OFTEC. This guarantees that your stove is installed correctly and safely and will function optimally.
Use the right fuel
Ensure you use quality fuel. Look for the Ready to Burn logo to ensure your wood logs are at or below 20% moisture content. Never used chemically treated wood or burn waste on your stove.
Regular servicing
Like any heating appliance, wood-burning stoves require regular servicing. The SIA recommends NVQ qualified sweeps for ongoing annual maintenance. Chimney sweeps are also valuable sources of advice for good practice and ensuring your stove operates efficiently and safely.

In today’s fast-paced world, stress and anxiety have become commonplace. While there are many ways to combat these issues, you may be surprised to learn that a wood-burning stove can have a profoundly positive impact on your mental fitness and wellbeing.
In this blog, we’ll delve into the ways lighting a wood-burning stove can benefit mental fitness, including reducing stress and anxiety, promoting relaxation and mindfulness. With Mental Health Awareness Week approaching (15-21 May), there’s no better time to explore this simple yet highly effective technique.
How lighting a wood burning stove can support mental fitness
A wood-burning stove is more than just a source of heat and can support mental fitness in multiple ways. The experience of making a fire, followed by the warmth and soothing crackling sounds it generates, creates a calming and meditative atmosphere that promotes relaxation and reduces stress. Focusing on the process of lighting and maintaining the fire can also help shift the mind away from negative thoughts and distractions.
‘Results indicated consistent blood pressure decreases in the fire-with-sound condition, particularly with a longer duration of stimulus, and enhancing effects of absorption and prosociality. Findings confirm that hearth and campfires induce relaxation as part of a multisensory, absorptive, and social experience.’
By incorporating wood burning into your self-care routine, you can enjoy a mindful and fulfilling experience that promotes mental fitness and overall wellbeing.
The physical/mental fitness benefits of wood burning
As well as providing a source of heat that is both sustainable and environmentally friendly, wood-burning can also benefit physical health. Chopping and carrying wood requires physical activity that can help improve cardiovascular health and build muscle strength.
These benefits to physical fitness have a positive knock-on effect to one’s mental fitness:
“There is a growing body of literature that recognizes the positive effects of exercise on mood states such as anxiety, stress and depression, through physiological and biochemical mechanisms…”
Additionally, the unique bone warming heat produced by your wood-stove promotes physical activity as it is a great way to ease any aches and pains of the day. For example, a long winter walk is far more tempting when you know you have a warm fire to cosy up to when you get home.
Wood burning as a type of mindfulness
Lighting a fire and tending to it requires a level of patience, focus, and attention to detail that can bring a real sense of calm and centeredness.
As the flames flicker and the wood crackles, it’s easy to become absorbed in the sensory experience of the fire and let go of distracting thoughts or worries. This type of mindfulness practice can be particularly beneficial for those who struggle with anxiety or stress.
How to get started
With the fire lit, sit comfortably with eyes open or closed and try focusing on the sound of the crackling wood and the warmth of the flames. Allow yourself to be fully present in the moment and let go of any distracting thoughts as they arise and simply return your attention to the fire.
Wood burning Increases bonding and improves relationships
Gathering around the fire with family and friends provides a sense of warmth, comfort, and connection that is often missing in our fast-paced, technology-driven world.
Invite friends or family to join you around the fire and enjoy the warmth and connection that it can provide. You’ll be surprised how much more the conversation flows when there is a fire crackling in the background!
Here are some quotes from some Charnwood customers:
“My grandchildren ask for the fire to be on when they are having a hot chocolate on a frosty day.”
“Winter evenings with friends. Whenever we have visitors during the winter, we always make sure the stove is running as this usually ensures nobody will request the television be turned on, leading to an altogether much nicer atmosphere with people actually chatting and engaging much more, rather than staring at the screen.”
“Chopping wood is a great way to relieve stress! Everyone congregates around the fire and the children like to help with the kindling etc. It just creates a special atmosphere.”
“The stove is the catalyst for family bonding, which helps with relaxation & mood improvement. It helps to unwind after a days exertions at work.”
“You can just gaze into the fire and be taken away from the stresses of work. It gives opportunity for the family to come together and talk. Talking just seems to come easier when siting around the stove.”
A wood-burning stove also has some very practical ways of reducing common life stressors. With energy prices going up and supply issues still a real concern, a wood-burning stove provides a great way to mitigate both worries.
Here are some more Charnwood customer quotes:
“We love our log burner. It makes us feel warm, safe and secure. It helps heat the whole house, which has proved an asset in power cuts. Nothing beats sitting in the living room with the warmth of the fire in the depths of winter.”
“Lighting the stove after a walk by the sea during winter is a joyful experience. Has helped to alleviate the worry of power failures as we live in an area prone to electricity outage during bad weather. Just knowing that we have our lovely stove for independent heat and low light is fab.”
“As an electric only house, we wanted a plan b during a power cut to heat the home”
“Having a wood burner means I am less vulnerable in power cuts. I can still have heating, boil a kettle, cook food if I need to.”

The government’s Environmental Improvement Plan 2023 outlines its strategy for the continued improvement of regulations for burning fuel at home. It will tighten limits on new stoves in Smoke Control Areas (not banning), expand solid fuel legislation to fuels burnt outside and implement measures to encourage the replacement of older appliances with modern wood-burning stoves.
These are regulations we support and believe will make a real difference. Despite this balanced government plan, there continues to be a fair bit in the news about wood burning stoves with some sensationalist headlines, untruths and misrepresented information.
Understandably these scare-stories can cause concern, so with this blog we will show you how to heat your home with a wood-burning stove without having to worry about PM 2.5 emissions.
Benefits of Using Wood-Burning Stoves
Wood-burning stoves offer a carbon-neutral and cost-effective way to heat your home without relying on electricity or other fuel sources. They provide energy independence and can be used in conjunction with renewables, helping make these technologies more viable.
They are an ideal source of emergency heating and can even be used to cook food – in fact a Charnwood Cooking Plate can transform your stove giving you even more cooking options. Wood-burning stoves also last for decades, providing an affordable source of heat for low-income households as well as significant well-being benefits.
PM 2.5 is fine particulate matter with a diameter of just 2.5 microns, which is approximately 30 times smaller than the width of a human hair. These microscopic particles or droplets present in the air can be damaging to health when inhaled in sufficient quantity and come from a wide range of natural and human-made sources.
The good news, however, is that 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 clearly positive.
When you consider that a candle, cleaning spray or even making toast can produce levels of PM 2.5 in the home far in excess of a wood stove, it does put things in perspective. However, whilst it’s impossible to remove PM 2.5 completely from our lives, there are ways to minimise your wood-burning stove’s contribution both inside and outside the home.
Choosing the right Wood-Burning Stove
The first step to minimising PM 2.5 starts with choosing a wood-burning stove that is the appropriate size for the space and is certified to the highest possible efficiency standards.
Whilst all Ecodesign rated stoves provide improved efficiency, some are undoubtably better than others. In fact, ClearSkies 5 rated Charnwood stoves are up to 48% more efficient than standard Ecodesign. This reduces emissions by up to 90% compared with an open fire and by up to 80% compared with older, basic stove models.
This is an exceptionally clean burn which unlocks all the benefits of wood-burning while keeping emissions to a bare minimum!
Minimizing PM 2.5 Emissions from Wood-Burning Stoves
Once you have the right wood-stove installed, the next part of the equation is using the best wood burning practices – we all have our part to play. Trusted Chief Medical Advisor Chris Whitty in his latest 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.”
Achieving the perfect cosy fire requires choosing the right wood. Charnwood stoves are designed to run on seasoned or kiln-dried wood with a moisture content of less than 20%, which results in a cleaner and more efficient burn. This keeps harmful emissions to a minimum and significantly improves efficiency while protecting your stove and chimney – saving you money!
Seasoned wood is wood that has been cut and usually allowed to dry for at least 6-12 months. You can roughly estimate if wood is seasoned by its lighter weight when compared to wet wood and telltale cracks in the end grain. However, to be sure, we strongly recommend using a moisture meter to accurately check the moisture content.
Alternatively, you can purchase kiln-dried wood from an approved firewood seller. Click here to search in your area.
To ensure optimal performance and efficiency, regular inspection and maintenance of wood-burning stoves is essential. This includes cleaning the stove and its components, inspecting for signs of wear and tear, and examining the flue and chimney for any blockages or other issues. Here are some of the key proactive steps to take, so you can enjoy the warmth and ambiance of your wood-burning stove for years to come while keeping PM 2.5 emissions to a bare minimum.
Use a stove pipe thermometer
A Stove or Flue pipe thermometer is an essential piece of equipment that allows you to accurately monitor your stove’s temperature. This helps burn wood efficiently, protecting your stove and chimney, while reducing emissions and maximising heat output.
As one Charnwood customer from the 2022 stove accessory survey said, “It makes it so much easier to see if my fire is working at optimum temperature and if I need to adjust the amount of wood/air flow.”
Additionally, we recommend keeping your stove glass clean so you can monitor your fire and gauge its intensity. As you become more experienced, you’ll be able to anticipate the necessary interventions for maximum efficiency.
Check the seals on your stove
Ensuring the seals of your stove are secure is essential to maintaining its efficiency and keeping any smoke out of your home. Visually inspect the gasket (rope seal) around the stove door; if it is not snug against the door, replace it. Additionally, check the seal around the chimney to prevent any leakage. Taking a few minutes to check your wood-burning stove seals will help you stay safe and warm all winter long.
If you’re unsure how to check the seals, refer to your stove owner’s manual or contact a qualified technician.
Don’t overfill the stove – allow for air circulation
When using a wood-burning stove, it is important not to overfill the firebox. Filling the firebox no more than halfway ensures that the fire has enough oxygen to burn evenly and efficiently. A tightly packed firebox can cause the wood to smoulder instead of burning, which can lead to creosote buildup. Creosote is a highly flammable substance and can be the cause of dangerous chimney fires. For a safer and more efficient burn, make sure to leave enough space in the firebox for air to circulate.
Clean out ash and soot from inside the stove regularly
Regularly cleaning out the ash and soot that builds up in your wood-burning stove is key to its performance and appearance. Clogged airflow caused by a buildup of ash and soot can cause the fire to struggle and reduces efficiency.
How often you clean will depend on how often the stove is used, but generally, it is best to do a thorough cleaning once every couple of weeks during the colder months.
We highly recommend using an ash carrier to make the process much easier and mess-free!

It is important to remember that all energy sources, including renewables, require compromise and tradeoffs to receive the benefits they provide. The key is to maximise the benefits while reducing the negatives. Wood-burning stoves are playing a pivotal role in helping families get through the energy and cost of living crises. However, we agree it is important to understand PM 2.5 emissions and to take steps to minimize them. By following the tips outlined in this article, you can heat your home with wood-burning stoves without excessive worry about PM 2.5 emissions.

I spent the weekend clearing and chopping a large Eucalyptus which had blown down in storms a few weeks ago. It was a magnificent tree and one which we were sad to see come down. Its beauty, however, went beyond its imposing stature. As logs were cut and split ready for stacking and seasoning to provide heat at a much later date, the beauty of creation’s ability to store energy was demonstrated in its fullness. Energy storage has always been a human challenge, but this tree had done it perfectly. Earlier that day I had been at Parkrun and the subject of wood burning had been raised in light of the Scottish government’s reported ‘ban’ on installing wood burners in new builds (which has caused problems for the Scottish Government): “It is just crazy, where is the common sense in that” a local businessman said to me. Indeed, as I looked at the logs I had just cut, I agreed – where is the common sense of not using this stored energy for heat? It is local, widely available, and it is nature’s gift. When we look out of our window we may see a number of energy sources – maybe some sun, sometimes the effects of wind, but almost always trees.
Despite the clear benefits of using wood as a fuel source, there has been much anti-wood-burning talk recently, not least in Scotland. So, are we losing our common sense? Are we disregarding nature? At Charnwood, environmental responsibility has always been a core value and driver of our business as we try and make a difference in what we do. We want to listen, we want to engage with the voices that are contrary to our views, indeed that is the way we learn. There is a proverb from the bible which says:
“Instruct the wise and they will be wiser still; teach the righteous and they will add to their learning.” (Proverbs 9)
We initially held back from engaging with the anti-wood burning lobby on social media. However, we eventually felt compelled to start pushing back on some of the misleading and untrue claims made by the Wood Burning London and Global Action Plan campaigns. As we started to engage more, we realised that there were a lot of different viewpoints, some of which we hadn’t considered fully before. In light of this, we wrote:
In this, we argued we needed to start believing the best in each other in order that we work together for positive solutions. In truth, this has been really hard. We have always sought to be polite – to engage well and be constructive. However, perhaps unsurprisingly, this is rarely reciprocated. In hindsight, maybe we should have paid more attention to the first part of the proverb:
“Whoever corrects a mocker invites insults; whoever rebukes the wicked incurs abuse. Do not rebuke mockers or they will hate you; rebuke the wise and they will love you”
We were certainly mocked, insulted, abused and hated! We are apparently representatives of the ‘Stink Industry’, our customers are ‘stokers’ and we have been given a new brand name ‘CharrredWood’. We were called liars, condescending and not genuine…. The claims went on, abuse was thrown our way and when we did invite more meaningful debate away from X we were accused of having bad motives and wanting to discredit people. When there seemed to be genuine concerns and we offered to engage in detail away from social media to find solutions, in most cases, those with the issues refused the offer of help and even called us creepy for offering! Our motives and funding were questioned, and we were accused of acting in bad faith. Some users have even learnt how to use AI images to produce grotesque anti-wood-burning memes. It was tempting to want to reply aggressively, but we tried to resist.
We know there are strong voices on both sides, and social media can breed one-sided arguments while amplifying negativity. But the intensity of the anti-wood burning sentiment online from certain groups was still a little unexpected. Engaging felt a bit like venturing into a lion’s den – or maybe a nest of angry wasps – we got our fair share of stings! Our words were sometimes twisted, and our motives misconstrued.
Here is one example of a social media post that highlights some of the challenges to the debate. An unwillingness to recognise the very real differences between different stoves and other forms of woodburning is not constructive. Obviously ‘good’ is subjective, but we think it is a justified adjective when you consider a modern stove, burned correctly, is up to 80% more efficient than an old stove and 90% more than an open fire. Additionally, emissions from modern wood stoves, when used correctly, are negligible. Burning dry wood (e.g. Ready to Burn certified) in an Ecodesign-compliant stove (e.g. clearSkies certified) makes up just 0.09% of total UK PM2.5 emissions. Source: NAEI(1).
Also, scaremongering tactics regarding an increased cancer risk to stove owners misrepresent the facts and is very unhelpful to all. This report undertaken by Dr Amanda Lea-Langton, (2) senior lecturer in Bioenergy Engineering at 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
-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. (Even the findings from the London Wood-Burning Project(3), who are anti-woodburning, back this up: “Use of the clearSkies Level 5 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.”)
-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 have greater health risk potential
Despite the hostility online, the experience did provide some value. We do recognise people’s concerns and understand some of the frustration. What was very apparent is that many of the most vehement anti-wood-burners have had very bad neighbourhood experiences of wood-burning. Pictures of smoky chimneys are too frequent, and, in all honesty, we would be complaining just as much if we had to live next to some of the chimneys in question. Undoubtably, there is a very real and present problem with the way that some people are burning their wood fuel which is something we rarely hear as most of the people we interact with at Charnwood HQ love their stoves. They find it has improved their health and well-being, keeps them warm and provides energy security – but we acknowledge that our experience on X has revealed there are others who have been very negatively affected by bad burning.
So where does this leave us – what do we do? We are passionate about wood-burning heating, to us and to many it seems like common sense. It makes use of a local, natural and renewable fuel source that encourages the planting and managing of forests and woodland which is important for improving biodiversity (4). We make Charnwood stoves here on the Isle of Wight, we employ local people and one of our company objectives is to make a positive difference to the local community. Sustainability is a core driver in our business, and we continue to seek ways to minimise our environmental impact. We are confident of the many benefits of wood-burning, however, we are not oblivious to the downsides and burning anything can produce bad particles. Although the improvements in burning technology have overall reduced wood smoke emissions significantly (1), if you have a neighbour who is burning badly, this is of little comfort.
However, we do need to be realistic about energy solutions and apply common sense to each situation. There will not be a one-size-fits-all solution. Heat pumps are the solution being pushed by governments at the moment, but the uptake has been really poor. Where around one million gas boilers are fitted every year there were only around 60000 heat pumps sold last year (5). Despite the best efforts of governments, consumers have been reluctant to install them and many who have, are left disappointed. I was talking to a local heating engineer a couple of weeks ago and he was telling me how he now has customers asking him to remove their heat pumps and instead install a gas solution. In Germany, part of the success of the AFD has been its opposition to heat pumps (6). Although heat pumps can work very well, they have limitations and when policymakers ignore these genuine concerns and try to push a one-size-fits-all solution, we can see it backfire. But in the same way that we need to be careful about over-pushing one solution, we also need to be careful about restricting other solutions because of their perceived negatives. Should we ban electric cars and battery storage because the metals used often come from mines using child labour? (7). Should we ban solar panels because most are produced in China using Uygur forced labour and some of the chemicals used are toxic (8)? And should we ban all solid fuel burning because of the problems of emissions in some cases? All of these are valid questions which are likely to make us feel uncomfortable, and our lived experiences will determine our responses. But instead of banning things and reducing our energy security and flexibility, should we not mitigate the negatives so we can take advantage of the positives?
All energy sources have upsides and downsides – are they low carbon? Are they emission-free at the point of generation? Are they emission-free at the point of use? Is the energy source sustainable? What about the manufacturing impact of the equipment? What about the recyclability of the equipment? In the UK we often congratulate ourselves on being well on our way to having sustainable energy, however as Sir Dieter Helm, Professor of Economic Policy at the University of Oxford points out much of this has been because we have deindustrialised(9). For example, closing the steelworks at Port Talbot won’t mean that we consume less steel. It will just mean that the environmental and carbon impact of the steel we use gets moved to another country often with less human and environmental protections than our own. The same could be said for importing wood pellets from North America to power the Drax power stations – we still use and generate the carbon here, even if it is offset where the trees are grown. We need to use the ‘common sense’ test, and both of these examples fail miserably.
Now more than ever, with so much instability in the world, we need a pragmatic and diverse energy mix that is resilient to future demands. We believe burning wood on modern wood-burning stoves is an overall small, but important part of this. By using logs from locally managed forests, and burning properly with locally made, long-lasting equipment which can be easily recycled at the end of its life, wood-burning stoves are one common sense solution for many situations. At Charnwood, we are investing in new technology which mitigates the negatives of wood-burning emissions. We have just launched the Skye E700 which uses electronic control to constantly monitor the fire and make automatic adjustments to ensure wood is always burnt cleanly and efficiently. The results are remarkable and build on the already large steps forward we have made in clean burning technology. What is more, wood burning compliments heat pumps very well. Whereas heat pumps struggle in cold weather, combining a heat pump with a stove works well and could increase heat pump uptake if encouraged. Indeed, in Norway, if a heat pump is installed a provision must be made for a flue to take a stove.
So,let’s use our common sense as we think about heating. We are continuing to invest in new technology which will allow us to burn wood more cleanly and efficiently. We know it is sustainable and a brilliant solution for many situations that have suitablewood fuel available. As an industry, we need to continue making improvements in our appliances to ensure overall air quality improves, but we also need to work together with other stakeholders to ensure that local instances of bad burning are eradicated. This might mean tougher penalties, improved education and it may include a stove swap-out programme to replace old appliances with cleaner ones.It may also mean other things, but to do this we need positive and constructive engagement. Will we get criticism? Of course, we will, and we will expect it – just take a look at the comments below when we post this article on social media! Sustainability, the environment and air quality are important issues, so we welcome constructive debate and criticism, we want to see real improvements so this time we just might not respond to the mockers. Instead,our efforts will focus oninnovation and developmentto overcome the challenges of wood-burning while further amplifying its many benefits.
We at Charnwood appreciate the work Mums for Lungs does in advocating for clean air. We share their concern for healthy homes and the environment. However, some recent information they released on wood burning does not reflect the latest available data which shows significantly reduced emissions from advancements in wood-stove technology and responsible fuel practices. Let’s explore some key points raised in their leaflet:
Air Quality Concerns:
MfL “Wood burning is a leading cause of PM2.5. Emissions of PM2.5 from domestic wood burning increased by 56% between 2012 and 2022, to represent 22% of overall PM2.5 emissions in 2022. This is more than all UK road transport exhausts (18%).”
The term ‘domestic wood-burning’ continues to mislead. The public understandably associates this catch all term most readily with wood-burning stoves – despite it being a combination of emissions including open fires, outdoor bonfires and old stoves. The actual contribution of modern wood-burning stoves is estimated by the UK government’s official figures at just 1-2%! (1)
And when good fuel practices are undertaken this reduces even further. (2)
As reported by the SIA “Last year…PM2.5 emissions from Ecodesign stoves burning dry wood fuel accounted for less than 0.1% of the UK total.”
MfL “There is no such thing as clean burning. The newest Ecodesign, Defra compliant stove emits six times more PM2.5 per hour than a Euro VI heavy goods vehicle.”
This stat has repeatedly been shown to be flawed and has caused much unnecessary concern.
Closer inspection reveals the data used to create this stat excludes 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 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.” (3)
It is fair to say that a 90% reduction in emissions, which is what modern wood-burning stoves offer, is clean burning. With 70% of wood burning in London taking place on open fires, modern stoves could reduce those emissions by 90% and that would certainly clean up the air dramatically!
Furthermore, it is important and pragmatic to say that the reality is there is no pure way to keep warm. Every heating solution, from gas and electric to wind, solar, heat pumps and nuclear involves tradeoffs and compromises. The key is to optomise these solutions and use them intelligently together to provide us with greater energy security and wellbeing. Read about wood-burning stoves co-heating future here.
Costs:
MfL “Wood burning is costly…”
Prices of all types of fuel constantly fluctuate and are dependant on many factors including availability and how much you buy. Wood is consistently one of the cheapest fuel sources available and as recently as 18 months ago was widely considered the cheapest fuel source! (4) What is constant is that wood is the only fuel source that you can collect yourself for FREE and is not subject to spiking due to global crises in the way that gas and electricity is. It also provides energy independence and security from outages caused by various factors from storms to supply issues.
Environmental Impact:
MfL “Wood burning is not a climate friendly way of heating a home. Burning wood releases more greenhouse gases than gas, oil or coal for the same amount of heat.”
Wood is a renewable fuel source compared with fossil fuels that take millions of years to produce. Additionally, acquiring the remaining fossil fuel supply requires increasingly destructive methods such as fracking and deep-sea oil drilling. Wood fuel, on the other hand, can be sourced locally and in harmony with the environment.
Sustainably harvested wood fuel can absolutely be considered climate-friendly because trees absorb carbon dioxide as they grow, offsetting the emissions released when burned. However, we acknowledge that responsible forest management and efficient burning practices are crucial to ensure true sustainability.
MfL “Leaving trees to grow and mature creates forests which capture more carbon and sustain a richer variety of species”
Managing woodland is vital for healthy forests and increasing biodiversity. Coppicing is an ancient woodland management technique dating back to the stone age used to ensure regular supply of timber and firewood and improve forest health. It involves felling trees at their base to create a ‘stool’ where new shoots will grow. Coppicing today is often used as a way of improving the health and biodiversity of a woodland area by opening it up to the sunlight and allowing a wider range of plants to flourish.
The National Trust say “Today, we use it at many of the places we care for to create a range of habitats for plants and wildlife – dramatically increasing the diversity of species that thrive in these areas.” (5)
According to the Woodland Trust’s 2021 report (6), the UK’s woodland cover has more than doubled in the last 100 years, reaching 13.1% of the total land area and 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 who in turn invest in looking after their woodland areas.
____________
We understand concerns about PM2.5 and we want to continue playing a key role in improving air quality. Modern wood-burning stoves are NOT the problem and the latest data shows that they can in fact massively improve air quality.
We would encourage everyone to come together to focus on the real issues that can make a genuine difference. Let’s encourage people to reduce bonfires, switch from open fires to modern wood-burning stoves, and burn wood responsibly and efficiently. This would make a huge difference while protecting our energy security.
Remember there is no 100% clean technology. Every heating source has its positives and negatives. Modern wood-burning maximises the many positives while drastically reducing the negatives.
On May 1st new government regulations came into force that restricts the types of fuel you can burn at home. We welcome DEFRA’s announcement, that going forward, only fuels that reduce air pollution can be burned in stoves and open fires in the domestic setting. That means coal and wet wood are no longer allowed to be used. Charnwood fully support this change and have long been producing exceptionally high-performance stoves already designed to run on approved wood-burning stove fuel.
The Best Wood-Burning Stove Fuel Options
Seasoned wood
This is wood that has been stored and allowed to dry until the moisture content has reduced to 20% or less. Freshly cut or ‘green wood’ holds around 60% water which causes far more smoke to be produced. It is for this reason we have long stressed the importance of using seasoned wood because it produces a significantly cleaner burn – reducing emissions by up to 50%. Additionally, improved efficiency equals cheaper running costs, while a cleaner fuel means your stove and chimney will require less maintenance. It’s win-win.
How to season wood in 4 Steps
1/ Split wood into logs in a size to suit your stove no larger than 15cm (6”) in diameter.
2/ Stack the wood in a place that gets plenty of sun and allows the wind and air to circulate. To avoid injury from falling logs, never stack above head height.
3/ Cover the stack to protect it from rain and snow. Make sure to cover the top and if you cover the sides as well, make sure the air can get in and that moisture is not getting trapped.
4/ Store the wood for 18-24 months, until the moisture content is below 20%. Test this with a moisture metre.
Different species of wood have varying qualities that effect their wood burning capability. We have compiled a useful chart with more information.
Another fuel that is DEFRA approved is kiln dried wood that is cut, split, and then dried in large ovens. This speeds up the drying process and means that there is always readily available fuel for your stove if your supply is short. Look out for the Woodsure Ready to Burn label which guarantees a moisture content of 20% or less.
While choosing the right wood to burn is important, having an efficient stove is also key. Most of the stoves we sell are Ecodesign Ready and our Island Stove is one of the very cleanest on the market.
Charnwood are proud to have stoves certified in the inaugural ClearSkies listing, an independent emissions and energy performance certification mark for stoves. Many Charnwood products carry a level 5 certification (the highest available rating) which guarantees performance levels exceed the minimum Ecodesign criteria by a sizable 30%. This is only awarded to stoves that significantly reduce particle emissions while ensuring high efficiencies and a superior flame picture.
