Jason Scarlett is a modern stove expert and woodsman exploring the real-life potential of renewables that promote our humanity and local green environment.

_________

1/ Jason, can you tell us how your early career, (such as your time spent working in Borneo) has inspired your commitment to the use of sustainable renewable energy sources and which of these sources has the most likely benefit to future generations? 
 

As with most people, my understanding of renewables, efficiency and sustainability has grown throughout my lifetime during an era of great change for humanity. I was born in rural Norfolk in a house with one open fire and can remember the blackouts during the workers’ strikes in the 1970s. We had prepaid meters for electricity and had to make sure we always had a 50p piece at the ready. Moving to the urban sprawl of Southend on Sea aged 8, I can remember my first experience with a gas fire. Until the age of 15, all I had known was one appliance that heated one room in the housethen came the revelation of full central heating…and a shower! 

Coming from a poorer background, efficiency and sustainability are important aspects of everyday life. My early years living in the countryside allowed me an understanding of nature that many towns folk miss out on, but my year working for the oil and gas industry in the Borneo rainforest, aged 19, was a real eye-opener to how we are destroying the planet. I saw firsthand how the extraction and processing of fossil fuels and the yearning of corporates to replace the forest with agriculture was devastating the environment and the local indigenous tribes that had lived in harmony with the forests for thousands of years. If people really understood where their fossil fuels come from and the devastation they create, then it wouldn’t be hard for them to link the current crisis to their convenient lifestyles. 

Chatting to the ruling/ wealthier classes of Malaysians about deforestation, the usual answer was ‘you’ve chopped yours down, why shouldn’t we’ and that got me thinking about the countryside that I knew in the UK. Whereas my belief before going to Malaysia was that rich biodiversity was only found in rainforests like Borneo and wasn’t relevant to the UK, in fact, the comment ‘you’ve chopped yours down’ gave me the realisation that our countryside and biodiversity was just a shadow of its former self. 
 

Returning from Malaysia, I built a fireplace and chimney business based on my unique skill set. Over the coming years, I worked on traditional fireplaces, chimneys and solid fuel heating systems which led me to researching traditional woodland management and modern renewables relative to heating our existing housing stock. The realisation that the remnants of our ancient forests once held rich biodiversity comparable to Borneo and could be replaced and enhanced through traditional native management techniques funded by my customers’ energy bills, revolutionised my ethics, working practices and the products I installed. Compared to all other renewable energy solutions, no others depend on replanting native trees and managing them like our ancestors who looked after their environment with sustainability and future generations in mind.  

To leave our descendants’ native trees and environmental know-how seems to me far better than leaving them expensive upkeep costs of follies like carbon capture machines or the perpetual engine that is replacing old solar panels or turbines that are at the end of their life. Plant a tree to be coppiced and it could be there for 1000 years, lay down a solar panel and replace it in 25! 

2/ The coppicing of woodlands looks to be a practice that was used globally pre industrialisation dating back to indigenous populations. Can you tell us why this practice was so important and why approximately only 14% of woodlands in Europe are now coppiced? 
 

The management of local environments evolved in line with the advancement of human civilization and was key to our existence. There are many forms of traditional management, including coppicing, coppice with standards and pollarding, that will be relevant to the locality and what naturally grows there. Similar modern approaches such as continuous cover forestry, permaculture and agroforestry are all currently being implemented and link strongly to traditional techniques.  

The use of firewood is the reason humans were able to survive in colder climates and so it was a very important commodity that happened to grow naturally. Understanding how to nurture the environment to give enough fuel and food to survive without having to roam was key for the development of early settlements. As communities grew, so did demand… nothing much has changed in that aspect, but when the only resource is from the local environment, the necessity for better efficiency, local know-how, improved agriculture and forestry techniques became ever more important. There are instances throughout human history that suggest the downfall of some civilisations was caused by their inability to balance sustainability with growth. During the Middle Ages the UK overused its resources and so developments in managing techniques during the 15th century followed by declarations from Henry VIII and writings from John Evelyn set the path for unique practices that could arguably be attributed to creating the modern world as we know it. 

Then along comes the industrialisation of fossil fuels and cheap wood imports, and wood fuel from the local environment becomes worthless, even more so because of industrial farming and forestry. In a capitalist society, if something is worth keeping then it will be kept. The reason for sympathetic woodland management decline is because it can take more time, money, labour, effort and specialist local know how than modern industrialised fossil fuel extraction and forestry techniques. It also doesn’t follow with the corporate mindset and mainly promotes a local economy headed up by local specialists. 

Whereas most of my knowledge about coppicing centres around Essex and the southeast, what I do understand is that some colder climates do have natural environments that have only a few species of tree that supports less biodiversity than a rich mixture of tree types. The industrialisation of forestry over the past 200 years has promoted the planting of monocultures across the globe that supports very little biodiversity. Planting one or two species solely to harvest by clear felling for a certain product using industrialised techniques has overwhelmed many green environments. We can see this practice across Europe.  

Portugal planted vast amounts of eucalyptus for paper, which is not an indigenous species and is blamed for many of the forest fires they now experience. In the UK we planted many poplars for use as matches, while chestnut was used for fencing. In Scotland there is much debate about the foreign Sitka spruce and pine forest monocultures that were planted, the forestry commission has recently updated guidance for planting mixed species in the future. 

In Los Angeles, there has been mass planting in urban areas of palm trees because they look nice while the surrounding forests have not been managed properly in the way that the indigenous people did for millennia. Again, this meddling in the local environment is misguided and has been a contributing factor to the recent tragic devastation. 

Monoculture for the sake of a single product and big corporate profits can be seen across the world and can be blamed for the loss of many habitats. In Borneo, the virgin rainforests I worked in have now largely been replaced with oil palm. The corporate takeover of our forests removes the connection of local sustainable management practices, such as coppicing that enhances biodiversity.  

3/ Would sustained local/global coppicing have helped mitigate the circumstances of climate change and find us in different circumstances today? 
 

Climate change is just one of the problems we now face and there seem to be many reasons apart from carbon why weather patterns are changing. What seems obvious to me is how forests play their part with weather and reduce how much heat is trapped in the ground. In Borneo, I would be woken up at 5 am to a biblical downpour outside but when I left for work at 6 am, the roads and urban areas were bone dry. The rainforest, however, held on to the moisture with noticeable increases in humidity and in the forests, it was slightly cooler. I often walk through local Essex woodlands midsummer and the temperature drops considerably under the tree canopy. Removing these natural environments surely plays a big part in the formation of clouds, wind and rain.  

The method of harmonious management of the environment has taken many forms that are relevant to the local climate, landscape and ecosystem. The systems each civilisation followed were carefully developed over thousands of years and were born through the necessity to survive. The added bonus of well-managed woodlands using coppice techniques is that the whole process can be carbon neutral (and possibly carbon negative). By only taking what the forests want to give in order to be healthy, ensures that the root systems, that store carbon, are not affected while promoting rigorous regrowth that in turn speeds up the carbon sequestration time of the carbon neutral cycle. 
 

My concept is that if people survived alongside their local nature, being part of the ecosystem, then they are the best source to understand how their local environment can survive and even be enhanced alongside modern lifestyles. Turning our back on our history and ancestral wisdom is easy if it is blindly fueled by a corporate takeover that sees no easy profit in our old ways. Surely, it’s better and morally right to work with the locals to enhance their local economy that relies on the sustainable natural products around them rather than chop it all down in favour of monocultures that decimate communities and landscapes just to feed corporate greed.  

4/ You place a great onus on the health benefits of switching off and staring at a fire. Is there a poignant story you might share with us, of how this has impacted a customer’s life you have worked with? 
 

What if our fixation on TV, computers, and phones is just a modern version of fire-watching? It’s the same endorphin release, which taps into our primal love for the flicker of flames. At what point in human history did we evolve to have sufficient concentration and the ability to contemplate, recalculate our methods and use language to communicate, plotting the activities for the next day? What else other than controlling fire gave us a feeling of warmth and security while allowing a time for the community to come together in social gatherings. The day is done, daily chores completed, night falls and the only reason we didn’t go straight to sleep like other animals is because we lit a fire. What superstitions, religions and beliefs evolved from around a fire while watching the random flame picture of this magical element. 

Over the past 50 years, there have been many attempts to recreate the real flame of a wood fire. Gas and electric fires with the best technology still cannot come close to the mesmerising effect of the random flame picture created from the gases released from wood. 

Modern society has changed exponentially over the past few generations, some of it in a positive way, while it can be argued that family cohesion has fallen by the wayside. Modern whole house central heating methods give a luxurious touch button warmth in every corner of every room that allows children to disappear to their own seclusion, usually armed with their own screens to fulfill their desire to ‘fire watch’. In the past, when there were no distractions from the TV and only one space was heated, the whole family sat around the fire, staring into the abyss while ‘talking’ amongst themselves. Many of my customers say that when the stove is on, their children are more likely to sit with them, reestablishing traditional family cohesion. 

One day last autumn was quite poignant, I was out servicing wood stoves that I had previously fitted and had two elderly customers booked in one after the other. The first lady, who lives in a standard Victorian house, was concerned about the current anti stove campaign. With tears in her eyes, she asked ‘are they going to take my fire away?’ She explained how the fire was her crutch during winter, not just for the warmth, but with her little dog laid out in front, it eased her loneliness and gave a feeling of security that is hard to explain. 

The second lady lives in an affluent mansion by herself, surrounded by expensive furnishings and trinkets, she has the best of everything. Again, with tears in her eyes she said ‘this stove is my best friend, I couldn’t live without it’ 

One of the reasons I love my job is because of the feedback I get from customers. Even those ‘middle-class’ customers who initially turned up at my shop in their new BMW and just wanted a stove ‘because their friends got one’, come back a year later to proclaim ‘what have you done to me, that stove is the best thing I’ve ever bought, I can’t leave it alone, I even love chopping and stacking the wood!’ 

It makes you wonder what’s missing in the modern world, we call it all progress, but is it really?

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. 

Please join the #PositiveWoodBurning conversation

The SIA invites everyone to join the conversation online using the hashtag #PositiveWoodBurning. Visit www.stoveindustryassociation.org to learn more about modern stoves, responsible wood-burning, and the many benefits this approach offers.

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)

“The light shines in the darkness, and the darkness has not overcome it.” John 1:5

The word ‘light’ originates from the Greek word to ‘portray, show.’ As we move into December, the reality of shorter days and reduced natural light becomes more apparent. There is a reluctance to leave our homes as we are beckoned to stay indoors and shielded from the elements. As if by magic, we reach the veil of darkness with short bursts of light in between the dark mornings and early evenings. The trees, holding on to the last of their gloriously Autumnal coloured leaves, but the bareness is growing more apparent. Though it is this light that keeps us buoyant through the darker months. As we consider this darkness, it gives us the opportunity to also think about light in its many forms.

The artist Dan Flavin said that light itself was art, and as we head towards the winter, this artist’s statement resonates with me more deeply. The miracle of light becomes particularly transparent with the weather patterns during the Autumn months such as anticyclonic gloom, that creates a wrapped silence to the day covered by dull and cloudy weather. The search for intermittent light through the changing weather patterns and the joy it brings on Autumn days is treated as a wonder by us all. The light almost seems unexpected and it turns in a moment, the shadows it casts take us through the days that begin to layer with the quest for staying cosy and keeping our mood buoyant. There is a curiously magical quality to light, feeling like a message from the divine and day to day through the darkness a temperate presence against the cold.

As our thoughts begin to turn to the end of the year with winter and Christmas drawing towards us, light plays a crucial part in the season. The putting up of decorations in public spaces, the dotting of fairy lights and discussions on when to put up the Christmas tree are all centred around bringing light into our homes and shared spaces.

Though as we consider light in the literal sense of daylight, or perhaps the light of a fire that also warms our homes, there is maybe another more metaphorical form of light, which could be the one of conversation. In consideration of the role ChatGPT plays these days, it’s said that speaking with AI is immediate and responsive. However, there is a striking difference between AI conversations and in-person experience. When talking by fire or at the dining table it’s notable how these responses are slower, with a combination of conversation that’s not always marked by words.

Historically artists have conjured conversation through the cafe culture of cities. Artists have ritualistically gone to the same spot to be sometimes alone, to watch and to speak with others. Anthony Bourdain, in his travels often remarked on the importance of the spontaneity of sitting at a bar, taking in the moment and talking to a stranger. In our fast-paced, uncertain world where somehow we are pressured to broadcast every event, as some digital communication, the unmeasured time we spend simply being is not spoken of much. Though it would be hard-pressed for even the most cynical of us to dismiss the power of time spent with another, whether that person is a friend or stranger the exchange of energy and presence is a light itself. The miracle of Christmas, and the stress often associated with gift-giving and cooking, can be replaced with the thought that this all gives us a moment, regardless of our faith to be with people, to listen and to share a light we all hold with others.

Suppose we were to instead consider light, in its many forms and remove the ‘Hallmark’ pressure of what things ought to look like, and draw from within, the light that can be shared from our own soul with both friends and strangers alike. Somewhat like the spread of a lit fire, we can provide warmth by the simplest acknowledgements of each other.

Finding light, particularly with the winter drawing in, is perhaps best found through time spent together and building lifelong memories.

The unique bone-warming heat of a fire and the magical dance of flames, have brought people together and offered them comfort throughout generations. Now, as our modern lives grow busier, we are rediscovering just how beneficial the soothing ritual of lighting a fire at home really is. Recent studies and traditional wisdom suggest that fire can offer much more than just warmth by helping us to relax, unwind, and transition from the stresses of the day into a peaceful restorative night.

Fire and its calming influence

Throughout human history, fire has been central to our lives and survival. However, it’s not just the life-giving warmth we’ve depended on. Studies indicate that fire can play a calming role, showing how campfires and hearths influence relaxation and even reduce blood pressure. One study demonstrated that blood pressure dropped significantly in participants who sat by a fire with the sound of crackling wood, creating a multisensory experience of relaxation. This effect was strongest over time, suggesting that watching and listening to a fire may have genuine physiological benefits.

Colours of fire and their potential effects

The colours that dance within the flames are also a key part of a fire’s allure. While science is still exploring the psychological effects of colour, there’s a long-standing belief that specific colours have unique impacts on our moods. The warm orange and yellow tones of a fire are thought to have calming effects helping ease fears and worries. This may be why, in the low light of an evening fire, people often find it easier to let go of their daily concerns, creating a comforting environment where the mind can more deeply relax.

The hypnotic patterns of fire

When a fire burns, it often moves in a subtle, spiralling and mesmerising spiralling way. This rhythmic, almost hypnotic motion of gentle spirals and sways of a flame are inherently relaxing to watch. While more research is needed to fully understand the psychological impact, many people report that the visual flow of a fire has a meditative quality, helping to reduce stress and encourage a sense of calm.

The sounds and calming frequency of a crackling fire

Alongside the visual appeal, the sound of crackling wood is another aspect that draws people in. As mentioned before, the cracking, rhythmic sound is soothing in itself, but it may go a step further. There’s some speculation that these sounds resonate at lower frequencies, potentially in harmony with delta brainwaves, which are the frequencies our brains emit during deep sleep. While more research into this specific effect is required, the idea that the sounds of a fire might help signal relaxation to the brain aligns with why so many of us find fires deeply restful, especially before bedtime.

A modern ritual for today’s world

Lighting a stove can be a simple, rewarding ritual that separates the stresses of the day from the calm of the evening. This intentional act of creating warmth and light helps signal to our minds that it’s time to unwind. Just as our ancestors used fires to ward off the dark and create a sense of security, today, we can use modern wood burning stoves to create a comfortable space for ourselves and our loved ones.

A wood-burning stove’s superpower is the ability to heat a space while offering a host of other benefits that other heating solutions just can’t match. They can transform any room into a warm, inviting space, improve well-being and offer energy security and independence. Stoves come in many sizes to suit the size of your home and the spaces you wish to heat. A 7kW wood-burning stove is perfect for those larger spaces needing just a little more oomph! 

In this blog we’ll give you the information and tools to decide if a 7kW stove is the perfect fit for your home. 

Why a 7kW stove? 

A 7kW stove is ideal for medium to larger spaces, typically ranging from 100 to 150 cubic meters, depending on insulation and if you have cavity walls. Unlike a 5kW stove, which is better suited to smaller rooms and well insulated modern homes, a 7kW model can provide enough warmth for larger living rooms with high ceilings and open-plan spaces. To ensure the best match, measure your room carefully and consider factors like insulation, the number of windows, and overall layout. Using a Stove Calculator or consulting a stove specialist can help you make the right choice. 

Maximising efficiency and safety 

To ensure safety and efficiency when choosing the location for your wood-burning stove we recommend consulting a HETAS-registered installer. They will guarantee that your stove installation meets all safety standards, considers chimney access, proper ventilation, and safe distances from combustible materials. 

The benefits of a 7kW stove 

Versatile installation options 

With its larger heat output, a 7kW stove can be installed in more substantial rooms or spaces with a higher heat demand. This includes open-plan kitchens, combined living and dining areas, or even conservatories. 

Eco-friendly and cost-effective 

Modern log burners are designed to burn wood (a renewable resource) cleanly and efficiently, helping reduce emissions, unlike older models or open fires. This makes them kinder on the environment and a cost-effective solution, particularly as energy prices fluctuate. 

Energy Security 

Burning wood from sustainable sources reduces your reliance on fossil fuels. Additionally, during power outages, a wood stove can serve as a reliable source of warmth, adding to your home’s energy security. 

Wellbeing 

The Charwood wellbeing study found that people and their families are getting significant well-being benefits from owning and using their stove. Learn more here

What’s your earliest food memory?

I think this might have to be a tart I used to have at primary school, it was a butterscotch fudge tart with custard, unreal.

Can you share any experiences of cooking on fire?

 

Two years ago me and my partner had an amazing experience in Norfolk staying in a cabin by Un.yoked. At the cabin they supply all the tools, logs etc to build your own fire and then cook on it. We had steaks with a soy sauce glaze and stir fried vegetables.

Do you think cooking on fire adds any additional flavour to food?

100%, especially to any protein. I don’t know anyone that doesn’t love a good bbq or campfire cooking. I feel there’s a real sense of nostalgia when cooking on fire or when the food catches that charred finish.

Are you able to share a simple recipe that we might make on the Charnwood Haven?

 

Pan-fried cod (also works great with Dover sole), brown butter, crispy capers, chervil, charred hispi cabbage, saffron aioli.

For the Cod:

• 2 cod fillets (about 6-8 oz each) or a 12-16oz Dover sole
• Salt & water for brine
• 2 tablespoons sunflower or rapeseed for cooking
For the Brown Butter and Crispy Capers:
• 4 tablespoons unsalted butter
• 2 tablespoons capers, drained and patted dry
• 1 lemon, juiced
• Fresh chervil, for garnish (or substitute with fresh parsley if chervil is not
available)
1. Cod – 2 fillets – skin on
Make a 5% brine (1000ml Water, 1000ml ice water, 100g Salt)
Boil the water, add the salt then wait for it to dissolve, pour the salty solution over
the ice water and wait for it to completely cool before adding the cod. Leave the cod
in the brine in the fridge for 45mins. One out of the brine, pat down dry with a
J-cloth and live skin side up in the fridge till cooking time.
2. Prep the hispi cabbage
Cut length ways into quarters.
3. Saffron aioli
Ingredients:
1/2 cup mayonnaise
1 small garlic clove, minced 1/2 teaspoon lemon juice
A pinch of saffron threads
1 tablespoon hot water Salt, to taste
Pepper, to taste

Instructions

Bloom the Saffron -In a small bowl, combine the saffron threads and hot water. Let it steep for about 5 minutes to release the saffron’s flavour and colour.

Mix the Ingredients:

In a medium bowl, combine the mayonnaise, minced garlic, lemon juice, and the saffron water (including the threads). Mix well. Season, add salt and pepper to taste. Mix again until all ingredients are well combined.

Chill:

Cover and refrigerate the aioli for at least 30 minutes to let the flavours meld together. Preparing the dish.

Char the cabbage:

• Heat a cast iron pan on the Charnwood Haven, add rapeseed or sunflower oil,
Char the cabbage on both cut sides then leave in a warm/hot place on the stove in
a metal bowl.
• Add the cod fillets to the same skillet with a bit more oil, once the oil is hot, skin
side down. Cook for about 3-4 minutes on each side, or until the fish is golden
brown and cooked through. The fish should flake easily with a fork.
• Drain the oil but keep the pan for the sauce
Make the Brown Butter and Crispy Capers:
• In the same skillet, reduce the heat to medium and add the butter.
• Allow the butter to melt and cook until it turns a golden brown colour and smells
nutty,
about 3-4 minutes. Be careful not to burn it.
• Add the capers to the skillet and fry them in the brown butter until they are
crispy, about
1-2 minutes.
Add Lemon Juice:
• Remove the skillet from the heat and stir in the lemon juice. This will stop the
butter from
cooking further and add a bright, tangy flavour to the sauce.
Assemble the Dish:
• Place the cooked cod fillets & charred cabbage on serving plates.
• Spoon the brown butter and crispy capers over the top of each fillet and hispi
cabbage. • Add a nice dollop of the saffron aioli
• Garnish with fresh chervil (or parsley).

charnwoodstoves

Charnwood are the oldest British manufacturer of wood-burning stoves, run by second and third generations of the family, dedicated to providing products of enduring design and of the highest quality. We have been leading the industry with breakthrough technology since 1972. Sustainability and a desire to create the most efficient stoves on the market have always been central to what we do.

Whilst, wood-burning stove technology has improved dramatically over the years, particularly with the introduction of Ecodesign and Clearskies regulations, there has still been some concern recently generated by the media about efficiency and air pollution. 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 tool to 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.

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.

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.
