A Balanced Look at Wood Burning Stoves: Addressing Concerns from Mums for Lungs

Author: charnwoodstoves

Published: 18 Mar 2024

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.

Fire & Progress: A Legacy of Warmth, Innovation, and a Sustainable Future

Author: charnwoodstoves

Published: 15 Mar 2024

Fire has captivated humans since the dawn of our existence, becoming a cornerstone of human progress, shaping technologies, and our societies. Its warmth is life-preserving and life-affirming, offering not just physical comfort, but also a sense of togetherness and well-being. It’s a symbol of community, a gathering point for storytelling and shared experiences.

Read on to learn more about the origins of fire and why it continues to captivate us

Fire’s role in human development

The earliest evidence of fire use dates back hundreds of thousands of years and was more than just a source of warmth – it was a catalyst for change. Firelight lengthened the usable hours of the day, allowing early humans to venture out of the darkness and push back against nocturnal predators. More importantly, it unlocked a treasure trove of possibilities:

Cooking

Raw meat became cooked meat, a transformation that improved digestion and unlocked new nutrient sources. Where as 100% of a cooked meal is metabolised by the body, raw foods yield just 30 or 40 percent of their nutrients. Cooking is believed to have played a crucial role in the development of larger brains, a hallmark of early human evolution.

Crafting tools

Fire’s transformative power also extended to shaping our tools. Wood, hardened by fire, became more durable for crafting spears and other hunting implements. Fire also allowed early humans to work with metals, leading to the creation of even stronger tools and weapons, which further advanced their ability to hunt and acquire resources.

Bricks and pottery

Fire transformed clay into sturdy bricks and functional pottery revolutionising construction and food storage. These innovations laid the groundwork for permanent settlements and the rise of early civilisations.

Fire: The heart of the community

Beyond practical applications, fire has woven itself into the fabric of human culture. The flickering flames became the focal point for gatherings, fostering a sense of community and shared experience. Stories were told, traditions were passed down, and social bonds were strengthened around the warmth of the fire. Studies have shown how hearth and campfires can influence arterial blood pressure and defray the costs of the social brain through fireside relaxation.

Fire also held a profound symbolic meaning across cultures. For some, it represented purification and transformation while for others, it acted as a bridge between the physical and spiritual realms. It was both an awe-inspiring and comforting force and a constant presence in the lives of our ancestors.

Balancing fire with progress

In the modern world, our relationship with fire has become somewhat more complex. Air pollution concerns associated with open fires and older, inefficient wood-burning stoves, have come to the forefront and gained a lot of press.

While alternative heating methods have emerged, and environmental awareness has rightly grown, the desire for the unique warmth and ambiance of a fire remains deeply ingrained in us. Fortunately, innovation has not abandoned fire. Modern technology offers solutions that allow us to enjoy the benefits of fire while minimising any negative impacts.

Ecodesign compliant wood burning stoves

Modern Eco Design wood-burning stoves significantly lower emissions compared to their predecessors – up to 90% compared with an open fire! They optimise efficiency and dramatically reduce smoke and particulate matter released into the atmosphere.

In fact, it has been found that burning dry wood (e.g. Ready to Burn certified) in a Ecodesign compliant stove (e.g. clearSkies certified) makes up just 0.09% of total UK PM2.5 emissions. Source: NAEI.

Clearskies 5 stoves

Even better are ClearSkies 5 Stoves which are 30% more efficient than Ecodesign. In fact, in a recent study conducted by Imperial College London a ClearSkies 5 stove was shown to improve air quality in the home, even when refueling.

As the UKs leading wood-stove manufacturer we are continuing to develop the technology and know we can improve efficiency even further still!

Sustainable forestry practices

Responsible forestry practices ensure that trees harvested for fuel are replaced, maintaining a carbon-neutral cycle. Locally sourced wood fuel helps support small businesses and reduces the carbon footprint of fuel transport.

Wood fuel is an important component of the woodland management cycle and plays a key role in maintaining woodland diversity, health and resilience. Choosing wood from well-managed woodlands allows you to enjoy the warmth of fire with peace of mind.

Renewable energy sources

While fire continues to play a role in our lives, renewable energy alternatives like wind, solar, and geothermal power play an increasingly crucial role in meeting society’s energy demands. However, we strongly believe in wood-burning stoves co-heating future, which involves filling in inevitable gaps in supply, aiding the transition to renewables and providing energy security in an uncertain world.

_______________

Fire has been a constant companion throughout our journey as a species. At Charnwood, we believe that fire, when harnessed responsibly, can continue to be a source of comfort and progress. By embracing cleaner burning technologies, burning wood correctly and supporting sustainable forestry practices we can ensure that we continue to benefit from the power and life affirming magic of fire.

Brrr to Bliss: From Disused Open Fireplace to the Magic of a Wood Stove

Author: charnwoodstoves

Published: 01 Mar 2024

In my charming but chilly Victorian end of terrace, winters were not something I particularly looked forward to. It was a constant battle against drafts, and strategising when to crank up the central heating to get most bang for the buck. So, after two cold dreary winters I decided something had to change – it was time to invest in a wood burning stove!

Read on to learn how I turned chilly evenings into toasty nights by the fire

I moved into my home 2 and half years ago now and in the centre of the main living space a large open fire place was sealed off and not being used. Mould was an ever present issue during the winters as the home was designed to have the heat and airflow created by a working fire. Whilst the gas central heating works, it is expensive and never gets the house feeling truly warm and doesn’t contribute to ventilation.

I didn’t want an open fire as I knew well enough that they weren’t very efficient and I am not a fan of a smokey living space. So, I feel the stars aligned when I started working at A.J Wells & Sons and I was finally presented with the perfect solution – one of their Charnwood wood-burning stoves!

As I researched, learning about Ecodesign and different outputs I was happy to discover that all Charnwood stoves outperform those standards offering greater efficiency and even lower emissions. Therefore I felt I could choose based on what would look best in the space which in my opinion was the Charnwood Country 4 Blu. It’s a classic looking design, the perfect size, and I was told one of the easiest stoves to use – I was sold!

I arranged for my installers to visit to measure up and assess my fireplace and chimney. They were intrigued by my slightly unusual fireplace which is open from two sides – a modification made by a previous owner no doubt. They assured me all would be well and we arranged a day for installation. Quick tip, stove installers are, unsurprisingly, incredibly busy in the autumn/winter months so it is well worth planning ahead and locking in your install date as soon as possible.

Installation day arrived, and the folks from Stoveteciw were fantastic. They set about first installing the chimney register plate which seals the large chimney opening and is where the flue from the stove can attach to create a seal. Next thing I knew they were up on the roof and threading the chimney flue liner down the chimney to attach to the register plate.

I chose a rear flue adapter for two reasons. It allowed me to place the stove where I wanted in the fireplace, but also it allowed a Charnwood cooking plate which was installed at the same time. As my confidence grows I’m going to be experimenting with a bit of stovetop cooking and whipping up some winter warmers. At the very least, boiling water for a cup of tea on a chilly morning is easy and way more atmospheric than the kettle.

After some final tinkering and fine tuning the stove was in place and the room was transformed. A focal point where there once wasn’t any. This wasn’t just any appliance; it was a promise of warmth, comfort and good times – all in less than a day.

It was a fantastic effort from the guys and it was clear they had done an expert job and left the place cleaner than they started! I strongly recommend using a HETAS registered installer to ensure the job is done properly and to get a HETAS safety certificate. This can be important for insurance purposes and is also useful if you ever want to sell your house.

I’d already purchased my bags of Kiln dried wood (read why that’s important here!), fire lighters and kindling in preparation for this moment and I was ready to go! I checked the stove essentials pamphlet that comes with all Charnwood stoves (also available online), to remind myself of the best way to light the fire.

Then came the moment of truth – lighting the first fire. Now, as with most household appliances with heating elements, the first time lighting your stove can create a slight smell, but that quickly passes and then your stove is fully cured and ready to be enjoyed. Following the top down, Jenga stacking method meant I had crackling flames and radiating warmth in no time – pure magic!

I’m now enjoying the end of the cold weather and far from dreading next winter. In fact, I think I’m going to miss the fire for a few months. It has become my go to way to unwind in the evening and the best way to put down the phone/laptop and let my mind decompress and relax away from a screen. I now fully understand what other wood-stove owners were saying when they described the many ways owning and using a wood-stove enhanced their wellbeing.

My final thoughts to those of you interested in a stove, I’d say, of course, do your research, speak to a Charnwood registered dealer/installer for advice on what your space needs and plan well in advance for next winter. Your future self will thank you!

More Than Just Heat: The Power of Modern Wood Stoves for Sustainability and Wellbeing (Insights by the SIA)

Author: charnwoodstoves

Published: 01 Mar 2024

We are proud to amplify the Stove Industry Association (SIA) and their excellent article that highlights the many benefits of having a modern wood stove in the home. We encourage you to visit the SIA website to read the full article and learn more about the SIA’s valuable work.

Here, we will look at some of the key takeaways!

General benefits & wellbeing

Modern sustainable wood-burning stoves offer a low-emission and highly efficient way to heat your home. When used correctly, they contribute to a reduced carbon footprint while warming your main living space with ease. This gentle radiant heat extends throughout your property, creating a consistently comfortable living environment.

A real fire can help promote feelings of warmth and security and provides a focal point for the whole family, benefiting mental wellbeing.

Anti-mould and damp

They’re highly effective at heating your space which combats drafts and cold spots, creating a consistently warm environment. Additionally, they help circulate air and ventilate your property, helping reduce condensation and moisture buildup, a common issue in older homes.

A roaring stove typically draws air and moisture from the room it’s in, before evaporating and expelling it through the chimney system. This can help alleviate the formation of mold and damp, creating a healthier and more comfortable living space.

Fuel security & independence

A wood-burning stove provides independence from the grid, ensuring you can heat your home even during power cuts. And unlike fluctuating mains energy bills, with a pre-purchased fuel supply, you gain control and cost-efficiency, knowing exactly what you’re using/paying to stay warm.

The SIAs key facts on PM & Carbon Emissions

“There is a world of difference between an open fire and a modern stove designed for precision combustion and maximum efficiency. Switching from an open fire to a modern stove will reduce PM emissions by up to 90%.”

“Scaremongering tactics about “domestic combustion” as a whole are unhelpful. Modern Ecodesign compliant stoves burning dry wood make up a tiny fraction of UK particulate matter emissions – less than 0.1% in fact. Source: NAEI “

“Using dry wood fuel is both sustainable and renewable; wood logs have the lowest carbon emissions factor of any domestic heating fuel at 0.01 kg CO2e per kWh. That’s 1/20th the carbon emissions of natural gas or electricity and 1/29th that of oil. Source: gov.uk”

“Burning dry wood (e.g. Ready to Burn certified) in a Ecodesign compliant stove (e.g. clearSkies certified) makes up just 0.09% of total UK PM2.5 emissions. Source: NAEI. Take care when choosing your appliance and your fuel to ensure that you minimise emissions and maximise efficiency.”

Biodiversity & the wood fuel industry

Choosing locally sourced wood fuel supports small businesses, reduces transportation emissions, and contributes to the health of our woodlands.

Sustainable wood management is crucial for maintaining their health and diversity, while helping reduce wildfires and providing a vital habitat for wildlife. By choosing responsibly sourced fuel, you can contribute to a more resilient ecosystem.

“Unmanaged woodland is bad for wildlife. At present 42% of UK woodland is unmanaged. Source: Small Woods Association”

SIA Report: Wood burning emissions DECREASE despite record year for stove sales

Author: charnwoodstoves

Published: 24 Feb 2024

We have been eagerly anticipating the updated figures for PM 2.5 emissions from ‘domestic burning’ as we knew this should go a long way to settling the debate that has been raging on socials and in the wider media this winter. The reason all eyes are on this data is because it reflects a period of emissions that coincided with record stove sales. Therefore, if anti-wood-burning campaigners were right then a significant increase in PM2.5 should, logically, be observed. However, as reported by the SIA, Defra have finally released their figures and it is official: PM2.5 from domestic burning has DECREASED despite record wood-burning stove sales over the same period.

The release of the latest air pollution data by Defra shows an 18% reduction in PM2.5 emissions nationally between 2012 and 2022.

Particulate emissions from “domestic combustion” fell between 2021 and 2022 with a 3.9% reduction in PM10 and a 4% reduction in PM2.5 from “domestic combustion”. The latest data also shows that PM2.5 emissions from the domestic use of wood fuel specifically fell by 2.7%.

Chair of the SIA, Andy Hill, commented:

“SIA members reported annual sales of over 200k units in 2022, a 40% increase on 2021. This increase was driven by several factors including spiralling energy prices and increasing consumer apprehension regarding grid reliability. What is clear from the latest data is that, despite an increase in stove sales, domestic emissions have come down. This points clearly and conclusively to the improvement in air quality that can be achieved by replacing open fires and older stove models with modern, Ecodesign design compliant stoves such as clearSkies certified appliances.”

“The SIA looks forward to being able to apportion the numbers more accurately once the NAEI publishes the detailed source and activity name data that drives the top-level figures released by Defra. Last year this clearly showed that PM2.5 emissions from Ecodesign stoves burning dry wood fuel accounted for less than 0.1% of the UK total.”

_________

We are delighted this data finally confirms what we have been trying to communicate about the benefits offered by modern wood burning stoves. But rest assured, it is our full intention to go even further in reducing emissions. Through further investment and technological advances and extending our hand to those across the aisle to collaborate.

In one of our most recent blogs, we called upon those seeking to ban wood-burning to open constructive dialogue so that we can potentially work together to make even greater progress reducing emissions. The data is conclusive, and it’s time to come together and focus on the pragmatic changes that will move the needle further in the right direction.

Wood-Stove Owner Tips to Help Prepare for the Winter Energy Crisis

Author: charnwoodstoves

Published: 14 Feb 2024

Whilst the notion that a colder winter follows a hot summer isn’t necessarily supported by science, it’s smart to hope for the best but prepare for the worst. With temperature records recently broken and weather impossible to predict, who is going to bet against it being a particularly chilly winter?!

With talk of gas and electricity prices rising significantly from October, it is understandable to feel somewhat alarmed. Rather than just feeling a sense of helplessness, we will discuss some tips for how stove owners can be proactive and soften the effects of the cost-of-living crisis. After all, the trusty wood-burner helped many homeowners through the oil crisis of the 1970s, and we’ll show you why it can still be relied upon more than ever in 2022.

Read on to get some stove owner tips (for all budgets) to help prepare for the winter energy crisis.

Get winter ready now!

Whether you’ve owned a stove for several years or are still considering buying one, it makes sense to start your preparations now. During the summer months, demand for stoves and spare parts, as well as stove installers and chimney cleaning services, reduces slightly and can make the process easier and sometimes a little cheaper.

Wood-stove owner tips to prepare for winter:

Clean your chimney and service your stove

We recommend an annual service for your chimney and stove. This ensures optimum performance and safety, meaning you are burning wood efficiently/cost effectively and avoid potential (expensive) problems down the line. We recommend speaking with your local dealer or installer about organising an annual service.

Explore how to clean your wood-burning stove!

Buy a great value & highly efficient stove

The Charnwood Country 4 Blu is fantastic value and a great long-term investment suitable for most homes. While the Country 4 is the smallest model in the Country collection, it still incorporates the ingenious features of the larger stoves and is exceptionally fuel efficient.

The Country 4 takes a decent sized log length of 332mm (13”) and has a rated output of 5kW and can be installed in certain situations without the need for external air – this is ideal for most sizable family rooms.

Fix up your existing stove

If you can’t afford a new stove, then the spares site could be just the solution to give your existing stove a new lease of life! We still recommend everyone upgrade to one of our new ultra-efficient stoves as soon as possible, but for those who are currently struggling financially, we hope the spares shop can help tide you over.

Heat Shields

Protect your home and benefit from redirecting your stove’s heat back into the heart of the room, further improving efficiency. Vlaze, our sister company, offer the original and best heat shields on the market. Check out our broad range of heatshields!

Source your wood early

Demand for wood has skyrocketed recently and this may have knock-on effects. It is prudent to source your wood from a local supplier now, so that you are winter ready and avoid any potential price rises as we approach the colder months.

Reduce your fuel bill – free sources of wood for your log burner!

1. Fallen trees

After a storm, fallen trees and branches become available which, with permission, you can collect, dry out/season, and use for firewood.

2. Industrial off-cuts

Woodworkers, sawmills, and joiners near to your home are worth contacting to find out if they ever have any off-cuts of untreated wood that they need to get rid of.

3. Freecycle

People often advertise free wood on sites like Gumtree and Freecycle for those who are happy to collect it.

Wherever you source your wood from, it must be untreated and free from paint, finishes or other potentially harmful substances. Also, check wood with a moisture meter and do not burn it unless it has a moisture content of less than 20%. This reduces harmful emissions and will increase the lifespan of your stove. For a list of the best types of firewood check out our Firewood chart.

Explore more on how wood is a sustainable fuel.

Save energy by cooking and heating at the same time

As well as heating your home you can save energy by cooking on your stove at the same time!

For some recipes, our blog has some great ideas…

Four things to cook on a stove top

If you want to take your stove cooking to the next level, keep your eyes peeled for our autumn stove release. The Charnwood Haven is a brand-new compact wood-burning cooker to celebrate Charnwood’s 50 years in business.

Here are some customer responses to our Wellbeing Survey in relation to owning a stove:

“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.”

“Back up for central heating given no of power outages,”

“As an electric only house, we wanted a plan b during a power cut to heat the home”

“more efficient than previous coal fire and, in extremis, if gas supply fails or is too expensive, will provide warmth.”

“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 peace of mind our customers get from knowing, whatever the weather or economic or political climate, they can access fuel locally to heat their home is huge.

Harnessing the Power of Wood Fuel: A Sustainable Approach to Home Heating

Author: charnwoodstoves

Published: 12 Dec 2023

Charnwood is passionate about championing wood as a sustainable and eco-friendly fuel source. As the world transitions towards cleaner energy, wood continues to be a renewable, local, and efficient option that works perfectly in tandem with other renewable heat solutions.

Wood fuel has multiple benefits

Wood isn’t just great for generating heat; it also contributes to the health of our environment and the well-being of our communities. So, it is great news that, according to the Woodland Trust’s 2021 report, the UK’s woodland cover has more than doubled in the last 100 years, reaching 13.1% of the total land area. Forest coverage is set to continue increasing which provides a host of benefits, including:

Local Jobs: Wood fuel production and distribution creates jobs and supports economies in rural areas. This is crucial for maintaining the vibrancy of local communities.

Harvesting & using wood sustainably

To ensure the long-term sustainability of wood as an energy source, it’s essential to adopt responsible practices including:

Silviculture: Silviculture encompasses the nurturing and management of woodlands. It’s the practice of controlling the growth, composition/structure, as well as quality of forests while supporting timber production. A wide spectrum of silvicultural systems exists, each tailored to specific woodland types and areas.

Practicing coppicing: a traditional method of harvesting trees by cutting branches and shoots, allowing them to regrow and provide a continuous supply of wood.

High-Efficiency Stoves: Using high-efficiency stoves that burn cleanly and efficiently, minimising emissions and maximising heat output.

Avoiding Freshly Felled Wood: Avoiding burning freshly felled ‘wet’ wood, as it produces higher emissions due to its high moisture content.

Why seasoned wood matters

Seasoned wood is wood that has been dried so that its moisture content is 20% or lower. This is crucial for several reasons:

Reduced Smoke Emissions: Seasoned wood burns with a cleaner flame, producing significantly lower levels of smoke and harmful pollutants.

Better Burning Efficiency: Dried wood ignites more easily and burns more evenly, ensuring maximum heat output and minimising waste.

Extended Stove Life: Burning seasoned wood helps to protect your wood stove from damage caused by excessive moisture and creosote buildup.

At Charnwood, we recommend using Woodsure wood. Woodsure is a UK-wide wood fuel certification scheme that ensures the wood you’re buying is sourced responsibly and is of the highest quality. Woodsure wood is always seasoned to the correct moisture content, ensuring you enjoy a clean, efficient, and eco-friendly heating experience.

Wood, when harvested and used responsibly, can play a significant role in a sustainable energy future. Charnwood are committed to creating a cleaner, greener future powered by renewable energy sources while preserving the natural beauty and wonders of our woodlands. Choosing your wood wisely and using best stove practices, you can be confident that you are contributing to a sustainable future while enjoying the warmth and comfort of a wood-burning stove.

How to Check Firewood Moisture Content

Author: charnwoodstoves

Published: 11 Dec 2023

When it comes to heating our homes, firewood is a popular choice. However, using wet or improperly seasoned firewood can lead to reduced efficiency, increased smoke and even potential chimney fires. This article will guide you through the process of checking firewood moisture content, understanding the ideal moisture levels, and recognising the importance of properly seasoned firewood for optimal burning.

Checking Firewood Moisture Content

What should the moisture level of logs be?

To achieve efficient and clean burning, firewood should be properly seasoned to reach an ideal moisture level. The optimal moisture content for firewood is generally considered to be around 15-20%. Anything above 20% is considered wet, while below 15% is considered overly dry.

How do you know if firewood is dry enough?

There are a few methods you can use to check how moist your firewood is.

Visual Inspection

Inspect the firewood for visible signs of moisture such as bark that is still attached, discolouration of the log, or a dull appearance. Wet wood tends to be heavier (because of the weight of the water) and may show signs of mould or fungi growth.

Sound Test

Tap two pieces of firewood together. If they produce a dull thud or a heavy sound, it indicates higher moisture content. Dry firewood will sound hollow and produce a sharper noise.

Moisture Meter

Investing in a moisture meter is an excellent way to accurately measure the moisture content of firewood. These devices use metal prongs to penetrate the wood and provide a digital readout of the moisture percentage. Because they provide a specific number, moisture meters are the most accurate method of determining firewood moisture content.

Why is firewood’s moisture level important?

Understanding the importance of firewood moisture levels is key to efficient and safe burning. Here are a few reasons why it matters:

Energy Efficiency

Wet firewood contains a significant amount of moisture, which requires extra energy to burn off. This energy is wasted as it is used to evaporate excess water rather than generate heat. Properly seasoned firewood with ideal moisture levels (15-20%) maximises energy efficiency.

Reduced Smoke and Pollution

Burning wet firewood produces more smoke, particulate matter and harmful pollutants. By using dry firewood, you can minimise smoke production and reduce environmental pollution.

Chimney Safety

Wet firewood can create excessive creosote build-up in the chimney, which increases the risk of chimney fires. Properly seasoned firewood has the right moisture content and thus reduces the likelihood of dangerous amounts of creosote building up in your chimney.

Can firewood be too dry?

While it’s essential to avoid using wet firewood, excessively dry firewood can also pose challenges. Extremely dry firewood burns quickly and can lead to an overly hot fire that may damage your fireplace or wood stove and is likely to be uncomfortable for you and your family.

The best way to check if certain firewood is too dry is with a moisture meter as it will give you an easy-to-read percentage – anything less than 15% is too dry. In the rare event that your wood is too dry, mix it in with regular firewood to help raise the moisture content.

How to Prevent Carbon Monoxide from Wood-Burning Stove

Author: charnwoodstoves

Published: 10 Dec 2023

Wood-burning stoves are a popular way to heat homes because they offer an unparalleled source of comfort and warmth, however, it is important to be aware of carbon monoxide (CO) and the potential threats associated with its emissions.

Carbon monoxide is a colourless, odourless gas that can be very dangerous if inhaled in high concentrations. In this article, we will discuss the dangers of carbon monoxide, symptoms to look out for and, importantly, effective strategies for preventing carbon monoxide issues when using a wood-burning stove.

Why CO Is So Dangerous

Carbon monoxide is a dangerous gas because it binds to haemoglobin in the blood and reduces its ability to transport oxygen effectively. This can lead to oxygen deprivation and carbon monoxide poisoning. The gas can accumulate indoors and pose a severe threat, especially in poorly ventilated spaces. Even low levels of carbon monoxide exposure can result in long-term health issues.

CO Exposure Symptoms to Look Out For

Recognising the signs of carbon monoxide exposure is key for early detection and prevention of severe consequences.

Headaches and dizziness are common initial symptoms of carbon monoxide poisoning; exposure can also cause nausea and vomiting, often accompanied by a general feeling of being unwell.

Excessive tiredness, confusion, and difficulty concentrating are further signs of carbon monoxide poisoning. These symptoms can be particularly dangerous as they may impair judgment and hinder your ability to recognise the risk.

If you or anyone in your home experiences any of these symptoms while using your wood-burning stove, immediately ventilate the area and seek fresh air, and consult a medical professional.

How to Avoid Carbon Monoxide Problems

While the effects of carbon monoxide inhalation can be severe, it is thankfully easy to minimise the risk by following some simple precautions.

Clean Out Your Wood-Burning Stove

Regular maintenance is essential for the safe operation of your wood-burning stove. Cleaning the stove and its flue system helps prevent the build-up of creosote, a highly flammable substance that releases carbon monoxide and can lead to chimney fires.

Regularly remove ash (leaving about an inch in the base) and debris from the stove’s interior, including the firebox, grate, and ash pan. Use a metal scoop or shovel designed for this purpose. Dispose of the ashes in a metal container placed away from flammable materials.

Get Your Flue Inspected Annually

It’s also important to have a clean chimney and flue. Schedule annual professional inspections and cleanings to remove creosote and other blockages from your chimney and flue system. A qualified technician will ensure that the flue is clear, reducing the risk of carbon monoxide build-up.

An annual inspection should include:

• Inspecting the flue for any cracks, leaks or damage that could result in the escape of carbon monoxide.

• Ensuring that there are no blockages or obstructions in the chimney, such as nests or debris. These can impede proper ventilation and increase the risk of carbon monoxide buildup.

• Assessing the combustion efficiency of your wood-burning stove. They will ensure that the stove is operating at its optimal level, minimising the production of carbon monoxide.

Provide Sufficient Ventilation

Proper ventilation is crucial to minimise the risk of carbon monoxide build-up. Ensure your stove is installed in a well-ventilated area, and that your home has adequate fresh air intake. Keep air vents unobstructed and consider installing a vent fan to improve air circulation.

Install Carbon Monoxide Alarms

Installing a carbon monoxide alarm is a crucial safety measure for any home with a wood-burning stove. These alarms can detect the presence of carbon monoxide gas and alert you to its presence, allowing for swift action.

Install a carbon monoxide alarm on each level of your home and near sleeping areas. Ensure they are mounted in accordance with the manufacturer’s instructions for placement, and test your carbon monoxide alarms regularly to ensure they are working properly.

Burn the Correct Fuel

Another important precaution to take is using only the correct fuel – this is paramount for safe wood-burning. Burn only seasoned hardwood that has been properly dried; it burns more efficiently, produces less smoke and reduces the risk of carbon monoxide emissions.

Do not burn treated or painted wood in your stove. These materials can release toxic chemicals when burned, including carbon monoxide.

With the colder, darker months fast approaching, autumn is well and truly upon us.

And, with chunky knits, boots and jumpers already making an appearance, many people are thinking about how they’ll keep their homes warm and snug during the winter months.

Over recent years, wood burners have increased in popularity, with many people considering them to be an effective way to heat their homes for less during the ongoing energy crisis.

However, it’s important to remember that not all types of fuel are suitable for use in a wood burner. In fact, using the incorrect wood can increase maintenance costs, deliver poor stove performance, and even prove to be dangerous.

Types of wood to avoid

Within this guide, we’ll take a look at the types of wood you should avoid or burn with caution when using your wood burning stove.

Old pallets and treated timber

However tempting it may seem avoid burning pallets and treated timber. Paint, varnishes and oils can give off harmful emissions and can damage your stove and chimney.

Pine

Because pine has a high resin content, it is not considered the best wood to burn on a log burner. It burns quickly and the resin can seep out and clog up different parts of the stove system, which can lead to a whole host of operational problems. If you do choose to burn pine ensure it is well seasoned.

Larch

Much like Pine, Larch contains high levels of resin, which forms sticky deposits inside of the stove and flue.

Poplar

Poplar doesn’t burn for long periods of time and, when it does burn it can be smoky. As a result, it isn’t a good choice for a wood burner.

Laburnum

Laburnum is poisonous when used as firewood so should not be used as fuel for a log burner.

Alder

Alder produces a relatively low heat output, and is renowned for popping and sparking as it burns. This type of wood burns quickly but produces very little heat.

Chestnut

Most varieties of chestnut are okay to burn on a log burner, however, you should be aware that they tend to spit and spark, meaning many people are reluctant to use them.

Cypress

Cypress isn’t ideal as your main firewood source as it provides a low heat output and doesn’t produce very good coals.

Spruce

Spruce produces little heat making it an ineffective fuel for a log-burning stove.

Willow

Firewood should contain a moisture content of below 20%. Willow tends to grow in wet soils or beside water bodies, giving it a high moisture content so if you choose to burn it ensure it is dry and well seasoned.

What wood can I burn on a log burner?

Although there are many types of wood that shouldn’t be used on a wood burner, there are also many that you can use for fuel, including:

Hardwood firewood

Hardwoods, including ash, birch, maple, oak, and the majority of fruit trees, are some of the best fuels for wood burning stoves due to the fact that they can burn for long periods of time while generating plenty of heat. Hardwood is also cleaner to handle than other types of wood.

Softwood firewood

Some softwoods tend to be cheaper than hardwoods and can also be used in your wood burning stove.
