Nye installs wood burning stoves across London through his work with Stoake, moving between Victorian terraced houses, community spaces and, at times, more unexpected settings such as galleries. His relationship with fire goes back further. After moving to Australia as a child, he grew up in a culture where fire was part of everyday life, through barbecues, gathering and outdoor cooking, but also something that demanded care. That early awareness carries through into his work today. He speaks not only about the practicalities of installation, but about the enduring place of fire in the home, the appeal of wood burning stoves as a carbon neutral heat source, and the advances in stove technology that have made them strikingly simple to use.

Do you have any childhood memories of being around a stove or fire?

I always loved fire growing up. My parents came over from India in the 1970s, and we did not have a fire in the house. But when I was a little older, we moved to Australia, where barbecues were a big part of life, so there was always a fire going, with people gathered around it and all that came with it. In Australia there is also a strong awareness of fire in another sense, and of the need to treat it with care.

After school, I started work as a gas fitter and, through working with other renewable technologies, found my way to boiler stoves and then wood burners.

Day to day, what do you find most interesting about the different places and projects you install stoves for? 

One of the great things about working in London is meeting so many environmentally conscious people, particularly because everyone lives so closely together. People want to use the right stoves and make sure they are properly maintained. The work takes us into all sorts of homes and buildings, most often Victorian terraced houses, and every project has its own character. You might be working in a family sitting room one day, then in a completely different kind of space, such as a community farm, the next.

Your work has also taken you into unexpected places, including installing stoves for exhibitions at White Cube. What was it like bringing the element of fire into a contemporary gallery setting?

We installed six stoves for the artist Danh Vo at White Cube in Bermondsey. They were six Skye 7s, all connected to a single terminal and flued together, which is not something you would normally do in a domestic setting. Because it was a temporary exhibition in an industrial space, Building Regulations did not apply in the same way they usually would. Seeing all six running together in a white gallery space was quite something. It was a very different context for a stove, and a fascinating project to be part of.

Sitting beside a fire is such an ancient human act. Why do you think there is so much misunderstanding today about the ecological role of the modern wood burning stove?

It is such an ancient human act. A fire makes a house feel alive as well as warm, and those of us who work with stoves do not much like being in a house in winter without one. A lot of the misunderstanding comes from the way the issue has been represented in the media. There has been a tendency to blur the distinction between an open fire and a modern stove, and to simplify emissions reporting in a way that has confused people.

A modern stove, used properly, has very low emissions compared with many other sources of emissions. In reality, the picture is more nuanced. We began installing wood burning stoves because they are a carbon neutral heat source, and we have been particularly grateful for advances in technology, especially in stoves such as

the Charnwood Skye 700. Customers are genuinely interested not only in how well these stoves burn, but in how easy they are to live with. With a stove like the Skye 700, you still engage with the fire, but in a very simple way. You light it, close the door and let the stove do its job.

Smoke is bad. There, we have said it. You may well ask what a wood burning stove company is doing admitting that. Surely, we should be trying to defend smoke, because that is what stoves do, right? 

Well no, absolutely not. For over 50 years at Charnwood, we have been developing ways of reducing smoke emissions in our stoves, because we want clean air! That is what we do.  

We strongly believe that heating with wood has many unique benefits, including sustainability, increasing wellbeing, and community. However, we also recognise there are downsides, but that is true of every form of heating and, indeed, most things in life. Our job as stove makers is to keep innovating so emissions continue to fall while preserving the many benefits that draw people to a real fire in the first place. 

Progress, and why it gets ignored 

Modern stoves are 80-90% more efficient than older stoves and open fires

We and others in the industry have been very successful in cutting emissions. Since 1970 we have seen a huge reduction in smoke emissions and the air quality in the UK has never been better. More recently, since 2018 UK Government statistics show significant reductions in PM2.5 emissions from domestic combustion, despite a lot more stoves being installed over the period of the pandemic. 

However, the media headlines again recently have been telling us how stoves are causing health problems, even including making us fat! 

So what is going on? 

Catastrophising and fear 

To catastrophise means to ‘overestimate the danger and underestimate your ability to cope’. 

Rev Nicky Gumbel writes: Catastrophising leads to fear and is the opposite of faith. Fear tells you that you will not be able to cope. Faith tells you that your Father in heaven knows when you will need strength to cope and he will supply all you need just in time. God will arm you with the strength that you need for whatever lies ahead.  

This is about life, but it also says something about the current debate, and indeed other narratives in the media. In many ways modern society has become more and more risk adverse and scared. Things that we have long understood carry some risk are now sometimes presented as far more dangerous than the evidence suggests. Irrational and exaggerated fears seem to be constantlyprojected onto us. 

Smoke, and what we have always known 

Smoke is just one example, and we have known for a long time that it is not good for us. Whether it comes from car exhausts, bonfires, or cooking sausages in a frying pan or on a barbecue, when we are faced with a plume of smoke we instinctively turn away or cover our faces. 

Because we know it matters, we have tried to reduce exposure in sensible ways. Smoking has been restricted because the whole point of smoking is to inhale smoke, and that is not good for anyone. Where smoke is a by-product of something useful, like transport, cooking, or heating, work has been done to minimise emissions through better technology, better standards, and better behaviour. That approach has worked, and the UK’s air quality is now cleaner than ever, even if some of that progress has come at the expense of those countries that make many of the products we use. 

The consultation, and what it is really asking 

Recently we have seen a government consultation asking whether regulations should be tightened further and whether warning labels should be placed on stoves and wood fuel. We would not oppose further improvements in regulation. However, the real-world impact may be limited, since such changes would not affect the large number of older appliances already in use or other forms of burning, including outdoor fires, which can produce far higher emissions. Modern Ecodesign stoves are already very clean by comparison. 

Warning labels are also likely to be met with public scepticism. The emissions produced inside the home from normal activities such as cooking, frying and even burning candles can often far exceed those from a well run modern stove. Placing warnings on stoves without acknowledging these wider sources risks creating a distorted picture of indoor air quality. 

This is why some observers worry that the consultation could drift beyond sensible improvements into something closer to regulatory overreach, with calls from ‘clean air’ activists to restrict or even ban modern stoves despite the progress already made. 

So, what is the objective? Good air quality or a ban on stoves? Let’s be clear, attacking the cleanest products is not the same as improving air quality. What is truly behind the motivation of those wanting a ban is difficult to understand, and it would be unfair for us to speculate. What we can explain however, are our motivations. 

Our motivations 

Our company objectives are to transform lives and delight customers. To delight customers is obvious, we need to do that to keep getting sales. Transforming lives is more broad. As Christians we believe that lives are ultimately transformed by knowing Jesus and in our company this means that we strive to provide good employment, be a good customer, and make a positive difference in our local community, the Isle of Wight. It also means that we have a responsibility for the environment. We need to ensure we are acting sustainably, again as Christians, we believe the world belongs and is loved by God and so we have a responsibility to look after it. 

Many of our customers tell us how much they enjoy the warmth and beauty of a real flame. A fire has a way of transforming a room, drawing people together and creating a sense of welcoming comfort in the home. This recent article by Prof. Mike Parrott speaks beautifully about the power of fire and how for most of human history the hearth was the centre of the home, not just for heat but for gathering, conversation and shared life. Even today the presence of a real flame still draws people together in a way few other household features can. 

It’s also worth remembering that in a world where gas prices can spike suddenly, as recent disruptions to global LNG supply have shown, it makes sense to look for solutions that strengthen the UK’s energy resilience while preserving the warmth and social value of a real fire. 

At the same time we must ensure air quality continues to improve. That is why we focus on designing products that burn as cleanly as possible, most recently our Aire Intelligent range being a giant leap forward. By reducing emissions and encouraging good burning practices, we aim to improve life not only for our customers but also for their neighbours and communities. 

A better response than catastrophising 

So let’s not catastrophise the effects of smoke. But instead let us innovate to reduce emissions, giving ourselves the ability to cope and enjoy the many benefits and beauty of wood flames and heating.

A more useful response to the latest headline

A recent monitoring study in Wales has made headlines after reporting higher PM2.5 exposure for children living in non-smoking homes where a “fuel burner or fireplace” was present, compared with non-woodburning, non-smoking homes. The research tracked 53 primary schoolchildren using backpack sensors and found the home environment was the biggest contributor to daily exposure. 

That should be taken seriously as PM2.5 matters, particularly for children. However, it is not accurate to read this as “wood burners automatically mean higher indoor pollution”. 

A 2022 review by Dr Amanda Lea-Langton of Manchester University found no scientific evidence of adverse health impacts from exposure to indoor air typically associated with modern enclosed wood burning stoves, while noting that other indoor sources, especially cooking, can release much higher levels of particulate matter. 

The big issue is not modern wood burning stoves 

When people say “wood burner”, they can mean very different things and all with very different implications. 

•An open fire potentially with wet wood 

•An older stove that is poorly installed or poorly used

•A modern, efficient ClearSkies stove burning dry wood  

These “wood burners” are not comparable when it comes to emissions and efficiency. A modern stove is up to 90% more efficient than an open fire and can even reduce PM2.5 in the home.  

This is why the phrase “wood burner” matters. It is a broad label that can hide the real causes, and the real solutions. 

More on the study’s wording 

Jason Scarlett, a modern stove expert and woodsman, gives an expert critique in a response shared on LinkedIn. 

“Terminology is used to identify woodburning that is vague … ‘fireplace or fuel burner’ could include open fires or glass fronted appliances burning house coal … smokeless coal, peat, dry wood, wet wood and gas … Without that granularity, the data cannot tell us whether a small number of poorly performing homes are driving the average, nor whether well installed, well used systems perform very differently.” 

That is not a technical quibble, it is the difference between a useful public health message and a blunt headline. 

If you do not sufficiently separate appliance type, fuel type, ventilation, and whether a fire was actually alight during monitoring, it becomes far too easy to collapse everything into “wood burning”, even though the real world is more complex than that.

What the monitoring in the study does add 

This work by no means settles the debate. It is a relatively small study and it reflects one place, one season, and a limited number of households. 

Its value, however, is that it underlines two practical truths and can help guide a measured response to improve exposure. 

1) The home is the main exposure setting 

Children’s PM2.5 exposure was driven more by time at home than by school or travel. 

2) Indoor sources stack up 

Indoor air is a mix of what happens in the home and how well the home clears it. 

Cooking is often the big PM2.5 source hiding in plain sight 

 

Many households don’t realise that cooking and even making toast can create far more PM2.5 than a wood-burning stove. As you can see from Firefly London’s excellent post, frying, grilling, and oven use can create very sharp spikes, even in homes with no stove at all. If ventilation is poor, those particles can spread beyond the kitchen and linger.  

This is exactly why indoor air quality should not be treated as a single source story. It is a whole home story. Cooking, candles, cleaning sprays, damp, and poor ventilation can all add up in everyday life. That is why the approach to indoor air quality needs to be holistic, not focused on one headline source. 

Modern stoves, used properly, are a different category 

A key detail often missing from public debate is when and how particles actually enter the room. It is not simply “a stove in the house”. It is the moments when smoke escapes, typically during lighting, refuelling, or poor burning practice. 

The London Wood Burning Project is especially relevant because it involved real homes, real behaviour, and indoor monitoring. It found that once a modern, high performing ClearSkies Level 5 stove was properly lit, refuelling did not increase indoor PM2.5, and in some instances indoor PM2.5 levels fell. 

So, when burning is efficient and contained behind a closed door, indoor pollution need not rise in the way many people imagine. This is exactly why it is wrong to lump modern stoves in with open fires and older appliances. It produces the wrong conclusions, and it pushes attention away from where clean air gains are biggest. 

What families can do right now about indoor air 

Families need practical steps that reduce exposure from all sources. 

Ventilation is the first line of defence 

If air is not leaving the home, pollution inevitably builds up. Extraction and fresh air make a measurable difference, especially after cooking. So don’t forget to turn on your extractor when cooking and regularly open your windows and “house burp” as the Germans do! 

Filtration can give extra control 

A good air purifier can quickly cut indoor PM2.5, especially in bedrooms where people spend a big chunk of their time. It is not a replacement for ventilation, but is a back up that helps when opening windows is difficult. 

Background levels can often sit low, then jump significantly during cooking. With extraction, a cracked window, and a purifier running, the numbers can drop back down again fast. The goal is not perfect air, but fewer big peaks, a lower daily average, and more control over the air children breathe at home. 

A clearer conclusion 

This latest study is a useful reminder that indoor PM2.5 can be higher in homes where solid fuel burning is present, if ventilation is poor and bad burning practices occur. 

However, we need to communicate more clearly that not all “wood burners” are the same.  

The most useful response is to focus on what reduces exposure in real homes most effectively. 

•Target the smokiest options, especially open fires and older, higher emitting stoves

•Use dry, certified fuel and burn well. You can read more about best practices here

•Treat indoor air as a whole home issue, with cooking and ventilation taken seriously 

If you would like some advice, your local Charnwood stockist can help you size and specify a stove, choose the right fuel and get set up to burn well. Taking action now can make next winter warmer, calmer and a little more in your hands.

Ofgem has confirmed a 2% rise in the energy price cap from the 1st of October 2025, taking a typical dual-fuel household bill from £1,720 to £1,755 per year, an increase of £35.14 annually. While modest compared with previous spikes, it comes at a time when many families are still watching costs closely. As the Stove Industry Association (SIA) explains, a modern, Ecodesign-compliant wood-burning stove can offer affordable, renewable heat that reduces reliance on grid energy and adds resilience when prices or demand peak. 

Why modern wood-burning is more important than ever 

Used correctly, today’s stoves deliver high, controllable efficiency on renewable wood fuel. They can: 

•Deliver highly efficient, controllable heat using renewable wood fuel.

•Reduce the need for expensive gas or electricity at peak times.

•Provide households with a reliable and affordable secondary heating option, adding energy security and peace of mind.

The Aire Intelligent range: smart control, simpler savings 

 

Alongside our traditional models, the Aire Intelligent range uses our iBlu technology to manage airflow automatically throughout the burn. That means easier lighting, steadier heat and a cleaner burn without constant adjustment. Many users also report significant fuel savings with up to 50% less wood being used compared with manual stoves, when using properly seasoned logs and running the appliance in automatic mode. 

The good news is if you enjoy hands-on control, you still can. One retailer summed it up perfectly in response to a Youtube comment 

YT Comment: “Looks very intelligent, but would it take away the enjoyment of controlling a stove? Bit like manual against automatic gearbox in a car?” 

Ecofiresstoves: “We see the Charnwood ‘intelligent’ as more like cruise control than a full automatic gearbox. It keeps everything running at peak efficiency in the background, but if you want to take the wheel and adjust things yourself, you can!” 

At a glance 

•The new Aire Intelligent rangeimproves the user experience by allowing you to just “Load it, light it and leave it” (with optional app insights if you want them).

•Achieve test lab performance with the highest possible efficiencies and lowest emissions by design.

•Enjoy a crystal-clear view of the fire and bask in the unique bone warming heat that only a wood stove can provide.

How to get the best savings 

Real-world performance depends on a few basics. To maximise comfort and minimise costs: 

•Use properly seasoned or kiln dried wood (≤20% moisture).

•Size the stove correctly for the room and property. Click here for our stove calculator.

•Install and service via a qualified professional and always follow the user guidelines.

•Let your intelligent stove run in its automatic mode for day-to-day use and adjust manually when you want a more hands on experience.

Resilience when prices change 

Combining efficient wood-burning with your primary system creates flexibility and resilience. When bills rise or when demand surges, you have a reliable renewable alternative that helps keep costs under control and your home nice and warm whatever the circumstances.

Modern Woodburing stoves key benefits  

• Cleaner air – continuous R&D has led to the Skye E700 and Aire Intelligent, which cut emissions even further than EcoDesign standards and can dramatically cut emissions from open fires and old stoves. Learn more here.

• Energy resilience – locally sourced wood offers a reliable and renewable back-up when storms, world conflicts or other supply issues disrupt the grid. Read more here.

• Healthier Forests – managed coppicing for firewood stimulates new growth and encourages greater biodiversity. Learn more here

• Well-being – studies confirm that a real fire lowers stress, brings people together and can significantly improve well being. Read more here.

Facts, not fear  

Modern clearSkies-certified stoves like Aire Intelligent cut particulate emissions by up to 90 percent compared with an open fire and around 80 percent versus an older pre-Ecodesign stove. Independent data from Defra’s latest National Atmospheric Emissions Inventory shows that cleaner appliances and dry-wood fuel are already driving down national PM 2.5 levels despite record stove sales. Yet some campaigns continue to cite outdated figures or lump all forms of domestic burning together which misleads the public.

We have repeatedly offered to share and discuss our test data and innovations with Global Action Plan and other groups behind Clean Air Night but, to date, have received no meaningful engagement. Our invitation remains open because we believe the best outcomes come from collaboration and accurate information, not scare-stories. 

Common sense prevails 

Recent rulings by the UK and Scottish governments, and even the Advertising Standards Authority, have all confirmed that modern Ecodesign stoves are part of the low-carbon solution, not the problem. Aire Intelligent embodies that direction of travel, delivering lab-grade cleanliness in real-world homes 

People, planet and prosperity

Dealers from across the UK, Europe, North America and as far afield as Australia tuned in for this year’s online Dealer Homestay. After several buoyant years, 2024 was undeniably challenging, however several factors including new legislation and an uptick in stove orders leave the industry optimistic about the winter season ahead. Stunning drone footage of the Isle of Wight coastline mixed with a factory tour set the scene for an event that highlighted Charnwood’s commitment to innovation, resilience and responsible wood-burning. 

Introducing Aire Intelligent – effortless wood-burning  

Building on the runaway success of the Skye E700, we revealed the next chapter in intelligent combustion: Aire Intelligent. The stove comes in three perfectly proportioned sizes. The 300 is ideal for snug spaces, the 500 suits most living rooms, and the 700 is designed for generous open-plan areas. At the heart of every model lies Charnwood’s I-Blu combustion technology. A built-in microprocessor that reads the fire in real time and continually adjusts the air supply, delivering laboratory-grade efficiency in everyday use. Early adopters report burning up to fifty per cent less wood while enjoying crystal-clear glass and scarcely any ash. Control is effortless: press the discreet button on the front or use the mobile app, then simply load it, light it, leave it and love it. 

Welcome to effortless wood-burning; welcome to Aire Intelligent.

A return to common sense – three rulings that changed the conversation

The first quarter of 2025 delivered a welcome reality-check for the wood-burning debate:

The Ministry of Housing confirmed that modern stoves will remain a permitted secondary heater in new homes, provided they meet Ecodesign and clearSkies criteria – ending speculation about an outright ban and giving self-builders genuine low-carbon choice.

Cosy Killer” campaign – Advertising Standards Authority issued Brighton & Hove City Council an advice notice over its Ad campaign linking stoves to “1 in 20 deaths”. The ASA agreed the statistics were unsubstantiated. Scare-mongering headlines are now starting to get the pushback they warrant.

After a rural backlash, the Scottish Parliament amended its regulations so that wood-burning stoves can be fitted in new homes, recognising the resilience they offer island and off-grid communities. 

With legislators north and south of the border and the UK’s ad watchdog all acknowledging the role of modern wood burners, they are starting to receive the credit they deserve for their key role in UK’s low-carbon, energy-secure future. Read more here.

The Lord replied, “My Presence will go with you, and I will give you rest.” Exodus 33:14

The world is in such a state of flux that even the advice of parents or grandparents in their eighties doesn’t quite hold the knowledge for what might prepare us best for the future. There are headlines that decree that AI is changing our lives and will be the source of creating further divisions in a world already so divided. It is enough to make us all want to take that one time heavily marketed ‘duvet day’. But somehow even the warmest duvet doesn’t give us the restful respite and genuine nurture of nature or the tranquility of trees. May brings us the blossom of Spring and notable shoots forming on trees. Burgeoning boughs give us the signs of longer, lighter days ahead and basking in a new outdoor room of many colours.

The tree, it seems, is literally the gift that keeps giving, through the way it absorbs carbon dioxide. Like us trees breathe — they absorb carbon dioxide and exhale oxygen. Forests in the US have been credited with removing three decades worth of greenhouse emissions from trucks, power plants and cars from the atmosphere. Walking in trees also helps our mental health, and releases phytoncides that provide a benefit to our gut microbiome. Our tree friends may stand still but there is always one close by. As we further our understanding of trees and how they communicate we are drawn into recognising that perhaps we too share in their sentient nature. In a recent project run by Trinity College Dublin, passers-by were given the opportunity to have a conversation with trees, through an AI language tool powered by the use of a localised battery. The tree’s feelings were analysed by sensors connecting to the tree’s bio electrical signals, which consider factors such as the atmosphere it exists within, including soil, wind and light. The answers were interesting. Translating these signals gives us a sense of their experience over the lifespan of a two hundred year old plane tree. This project gives us the ability to connect with nature’s network, to gain an understanding of our partnership with the tree, and a wisdom that is almost incomprehensible in our short span on this earth.

This recognition is not something new to indigenous cultures. Trees are seen as an integral part of their culture, rather than something to be managed. They view trees and their supporting network of fungi, birds and animals, as an instruction on how to live, and a demonstration that building community requires the inclusion of everyone and working together in an interconnected way. Indigenous populations, which make up 5% of the world’s global population, safeguard 50% of the world’s biodiversity. Their long traditions of spoken stories mean that this safeguarding and intrinsic connection to nature is as natural for them as it is for us to awaken and brush our teeth. We now understand more that the pressing issue of climate change is something we as individuals need to act upon, rather than delegate in our minds to activists and government. The issue of climate is affecting even our most basic considerations such as heating our own homes. The desire for warmth is not just a practical requirement but one that sets the scene of invitation and warmth and ensures that home is a place of rest. The wood burning stove addresses both the issue of climate and creates restfulness, fulfilling both these needs.

There has been some misunderstanding around woodland management and the use of timber for woodburning. Understanding this type of management is not something we are necessarily drawn to think of day to day. Those among us who are gardeners or even curious novices, understand the benefit of pruning for growth, which could perhaps be a good analogy for how we might understand sustainable woodland management. Ancient practices of coppicing woodland encourages biodiversity, while also providing a sustainable heat source for its local population. Indigenous people across the world have always managed forests in this way. Over centuries, they have found this an effective way of also preventing the wild fires that cause untold damage. It has been proven to work more effectively than the more contemporary methods of fire suppression.

This unity of thinking found within the tree network and Indigenous guardianship shows us the benefits of communing with the ancient wisdom and mortality of the tree. During a morning walk through a quiet park the other day, I was moved from the chatter of birds to a lone saxophonist playing face to face with a tree. At first, it seemed like they were in conversation. However, on further inspection, the musician was using the tree’s shade so he could see his music. I left feeling a little disappointed by my romantic vision of this commune with the tree. But maybe in fact, the tree was working its restful silence, watching, being and waiting for us to connect. Nature has long been patient with us, maybe it’s time for us to work with the trees, so we can all be more restful.

At Charnwood, we’re in full support of the Stove Industry Association (SIA) launching the #PositiveWoodBurning campaign to highlight the many environmental, economic, and personal benefits of modern wood-burning stoves. Running for two weeks from 15th January 2025, this campaign is an opportunity to shine a spotlight on how responsible wood-burning can be a key part of a sustainable and low-emission future. 

Modern wood-burning stoves: The difference is clear

 

Efficiency and sustainability are more important than ever and modern Ecodesign-compliant stoves are an innovation-led led response to these demands. Compared to older, inefficient models or open fires, these stoves can reduce particulate emissions by up to 90% while providing families with a reliable, cost-effective heating solution. Meaning no matter what’s going on in the world with energy prices/availability, they can always heat their home! 

By using dry, seasoned wood— with a moisture content of 20% or less—modern stoves deliver optimal performance, generating more heat while using less fuel. This simple change not only enhances efficiency but also significantly lowers emissions, making it an environmentally responsible choice too. 

A campaign rooted in awareness and action

 

The #PositiveWoodBurning campaign is not just about stoves; it’s about building awareness of the broader benefits of sustainable wood-burning: 

Emission Reductions: Modern stoves produce far fewer emissions than outdated systems or open fires, making them a key ally in improving air quality. 

Forest Health: Responsible wood-burning supports active woodland management, encouraging biodiversity and reducing the risk of forest fires. 

Energy Security: With modern wood-burning stoves, households can rely on a renewable, locally sourced fuel that offers independence from volatile global energy markets. 

• Wellbeing: Find out why 93% of wood stove owners say it helps their wellbeing! 

As Andy Hill, Chair of the SIA, highlights, “Modern wood burning stoves are not only a cost-effective and low carbon heating solution, they also play a crucial role in reducing emissions compared to other ways of burning wood such as open fires. By using dry wood, we can ensure that our stoves operate at their highest efficiency, providing warmth and comfort while minimising our environmental impact. We believe that through this campaign, we can help educate the public on the benefits of modern wood burning and encourage a shift towards more sustainable and lower emission domestic combustion practices.” 

Why now? The case for positive wood-burning

 

Recent global challenges underscore the importance of reliable, sustainable heating. Energy security is a growing concern in the UK, with limited gas reserves and increasing reliance on imports. Modern wood-burning stoves offer a vital alternative, providing homes with consistent heat even during power outages or supply disruptions. 

Moreover, the environmental benefits of positive wood-burning cannot be overstated. By combining advanced stove technology with responsible fuel use and proper maintenance, households can contribute to a more sustainable future without compromising comfort or convenience. 

Best practices for responsible wood-burning

The #PositiveWoodBurning campaign offers practical advice for homeowners to get the most from their stoves while minimising environmental impact: 

Choose the Right Stove: Ecodesign-compliant and clearSkies-certified appliances are up to 90% cleaner than open fires and significantly outperform older stoves. 

Use the Right Fuel: Opt for wood with the Ready to Burn logo, ensuring moisture content is at or below 20%. Avoid chemically treated wood or waste materials. 

Regular Maintenance: Have your chimney swept and stove serviced annually by qualified professionals. The Federation of British Chimney Sweeps has links to all the main sweep associations.  

Proper Installation: Ensure your stove is installed by a competent person registered with HETAS or OFTEC for safety and performance. 

Follow Manufacturer’s Guidelines: Adhering to the manufacturer’s instructions ensures optimal stove performance and longevity.

For generations, wood-burning stoves have offered warmth, comfort, self-reliance, and a connection to one of nature’s oldest renewable fuels. At Charnwood, we believe these qualities must be closely aligned with responsible design – ensuring the timeless joy of a real wood fire has a valuable place in an increasingly environmentally and health conscious world. 

A proven record of facing challenges head-on 

While older stoves improved on open fires, there was still significant room for improvement in terms of efficiency and emissions. As we all learned more about PM2.5, the wood-stove industry tackled the issue head-on through technological innovations including: 

Advanced firebox design 

High-efficiency combustion systems 

Precision air controls 

Intelligent microprocessor controlled stoves 

Modern, Ecodesign-ready stoves now significantly reduce PM2.5 – by up to 90% in many cases when compared to older stoves and open fires. These improvements arose from dedicated innovation and a willingness to embrace new scientific insights. Thanks to independent testing and ongoing refinements, today’s stove owners can be confident their modern appliances, used appropriately, are both cleaner and more efficient than ever before. This track record underscores the integrity of our industry: we see challenges, respond with research and engineering, and deliver on our promises. 

Emerging science on Ultrafine Particles (UFPs) 

Now, scientific focus is turning to ultrafine particles. These are smaller than PM2.5 particles and are found everywhere. From road traffic and industrial emissions to sea spray, mushroom spores, laser printers and even the simple act of peeling citrus fruit. Their potential impacts on human health are not fully known and are still being investigated: 

UFPs can arise from activities at a distance – such as large-scale industry or busy motorways far from our homes – but the reality is that winds can carry these particles over vast areas. Pinpointing an individual source’s contribution to local air quality is extraordinarily difficult. 

The WHO determined that there was not enough data to provide guidelines for ultrafine particles (UFPs) – aerosolised particles measuring as little as 0.1 micrometers in diameter or less.(1) 

Studies and risk assessments remain inconclusive. As of now, scientists do not fully agree on the level of health risk posed by UFPs specifically, nor do we have a comprehensive understanding of each source category’s relative contribution. (2) 

In this context, it is too early to claim a direct, confirmed health risk from UFPs emitted by any single source, including wood stoves—particularly as stoves contribute only a small fraction of overall UFP emissions compared to transportation, industry, and natural occurrences.

Nevertheless, at Charnwood we approach new challenges as we always have – by embracing further research. We continue to push for greater efficiency gains/emission reductions and are monitoring developments in filtration technology and beyond. 

Overestimation and real-world context 

As we’ve seen before with PM2.5, there is a desire from some to overestimate the impact of modern wood-burning stoves and the same will likely happen with UFPs. However, no matter the heating method – whether it’s a gas boiler, electric, heat pump, wind or solar – ultrafine particles inevitably arise somewhere along the chain including drilling, shipping, road transportation and burning for fossil fuels, large-scale manufacturing of high-tech components etc. All these processes can generate huge amounts of UFPs and other sized particles at different stages capable of contributing in varying degrees to the levels in the air. 

A 2024 report by the Institute for Fiscal Studies (IFS) found that: Average PM2.5 levels in England fell by 54% between 2003 and 2023, reaching a 20-year low.(3) 

Despite frequent sensational headlines, the IFS explicitly noted a tendency to “overestimate the importance of wood burning” in overall PM2.5 apportionment. 

They clarified that “emissions may be dispersed by the wind or brought to the ground by rain, meaning a large emission of PM2.5 may not translate into significantly higher amounts of PM2.5 in the air we breathe … Considering only primary PM2.5 tends to overestimate the importance of wood burning as opposed to transport and energy combustion.” 

By focusing broadly on “domestic wood burning” and neglecting the huge performance gap between old, inefficient stoves and modern designs, some public campaigns overlooked real opportunities to tackle air pollution more effectively. The same may prove true for UFPs, where conflating all wood-burning – regardless of technology or best practices – could distort our understanding of actual emission levels.(4) 

The unique positives of Wood Burning 

 

While every form of home heating solution has an environmental footprint somewhere along the line, only wood-burning brings such a variety of unique benefits when done responsibly: 

Energy security & resilience
Wood stoves offer a degree of independence during power outages and times of high energy prices. They can heat a home even when the grid is down or gas supplies are uncertain and they don’t rely on intermittent sources such as sun and wind. 

Sustainably managed woodlands
Responsible wood-burning supports active forest management. Using locally sourced firewood encourages healthy woodlands when replenished responsibly. 

Lower carbon footprint (with good forestry practices)
Trees absorb carbon dioxide as they grow, making well-managed wood fuel part of a more balanced carbon cycle. 

Ambience & wellbeing
There’s an intangible comfort to a wood stove’s gentle crackle and glow – a focal point that brings the family together. 93% of stove owners say it has a positive impact on their well-being(3)
(See our blog on “The Real Reason People Install a Wood Burning Stove” for more.) 

Compatibility with older homes
Many traditional homes were designed with solid-fuel heating in mind. Removing or neglecting this feature can lead to inadequate ventilation and moisture problems, sometimes resulting in mould or dampness. By using a suitable wood stove, occupants can maintain the home’s historical character and proper airflow patterns. 

A big future role for positive wood burning 

Beyond emission numbers, positive wood burning is about family comfort, reliable energy, and the stewardship of our woodlands. At Charnwood, our mission is to safeguard this heritage while meeting and improving upon modern standards – through rigorous research, responsible innovation, and genuine care for our customers and the environment. Our success in cutting PM2.5 emissions so far shows our commitment to leading the way. As emerging science investigates UFPs, we promise to bring the same diligence to any future challenge, ensuring wood burning remains a truly sustainable, rewarding choice that gives us energy security. 

We can’t – and shouldn’t – try to live in a world with zero UFPs, as they’re a natural byproduct of countless human activities and processes that are vital for progress. But we can be sensible, realistic, and evidence-based in reducing emissions where we can – just as we have done with PM2.5. With news recently that Britain’s gas storage levels are “concerningly low” it’s clear that modern wood-burning stoves have a big role to play now and in the future.(5)
