Smoke and Mirrors: Exposing the Flawed Data Behind the War on Wood Stoves

We don’t enjoy having to react to media sensationalism, however, there are times when it feels important to set the record straight. A negative narrative is being unfairly manufactured around the wood-burning stove industry, by anti-woodburning groups such as the ‘London Wood Burning Project’ and ‘Clean Air Hub’. Their campaigns repeatedly use misleading claims and stats to scare the public and they refuse to answer questions directly when challenged.

Therefore, we feel it is a duty to set the record straight, so people don’t succumb to the haze of misleading information out there. In this blog, we will shed light on some of the flawed data and unfair generalisations anti-woodburning groups are using.

What do they mean by wood-burner?

The campaigns paint a distorted picture, often using anxiety-inducing imagery and negative attention-grabbing headlines based on sweeping generalisations and weak or inaccurate data. They continue to mislead the public using stats that lump modern wood-burning stoves in with outdated, inefficient models, open fires and bonfires. It’s like saying cyclists are equally to blame for traffic congestion/emissions as lorries and private cars just because they all use wheels!  

They combine emission sources for a more impactful number, and then claim 17% of London’s emissions come from ‘domestic wood burning’ or ‘wood burners’. Catch-all terms the public understandably associate most readily with wood-burning stoves – especially because they create ad campaigns which prominently feature images of wood stoves. However, the actual contribution of modern wood-burning stoves is estimated by the UK government’s official figures at just 1-2%! (1)  

Differentiating between wood-burning practices is vital for progress  

Firefly London points out: “The irony of the billboard placement is that London’s tube network has appalling air quality, with PM 2.5 readings peaking at 600-700 ug/m3 – that’s 100 TIMES MORE PARTICULATES than an average London street…”

It is essential to differentiate between various forms of wood-burning. Chief Medical Advisor Chris Whitty in his report acknowledges this saying, “For air pollution emissions, there is substantial difference between the different open fire and stove designs, the age of the appliance and how well maintained it is, and the moisture content of the wood, for those who want to burn wood.”(2) 

While Ecodesign-compliant stoves are up to 90% more efficient than an open fire, ClearSkies Level 5 stoves, are even better still. They surpass Ecodesign standards, offering a further reduction in emissions by up to 30%! (3)  

This is where the anti-woodburning strategy is so incredibly counterproductive. In London 70% of wood burning still occurs on open fires. (4) If people were widely encouraged to switch to one of the many modern and efficient wood-burning stoves available, it would massively reduce urban PM 2.5 emissions. Just think, the emissions of 70% of London Wood burning could be reduced by 90%!  

Modern wood-burning stoves could help London reduce open-fire emissions by 90% ! 

 

PM 2.5 comes from such a wide array of natural and man-made sources that a zero-emission world is impossible! The best we can do is reduce them as much as possible while maintaining our ability to heat our homes. That is exactly what modern wood-burning stoves help achieve.   

If improvements were what the anti-woodburning brigade was truly after, it doesn’t make sense to ignore the vast advancements in clean-burn technology now defining modern wood-burning stove heating. They are the ones being ‘careless’. 

PM 2.5 perspective: How stoves can HELP improve indoor air quality 

This is also totally misleading. We could draw on our sources, but more powerfully we can draw on the London Wood-Burning Project’s own report as a rebuttal to this one. 

On page 71 of their 127-page report (5), we find the page titled Key Findings. Below are 3 crucial pieces of information from this page:  

1/ Use of the clearSkies Level5 stove (which is Ecodesign compliant) demonstrated some benefits for indoor air quality. Indoor PM2.5 did not increase when adding fuel to the stove once lit… At times there was actually a decrease in indoor concentrations of PM2.5 when adding fuel.  

As we have long pointed out, a properly functioning modern wood stove draws particulates out of the room and up the flue, helping improve air quality and ventilation in the home. The stove used in this study was our Charnwood C-Five.  

2/ Increases in pollutant concentrations may be more affected by participant technique or specific airflow characteristics of an individual appliance, rather than to the type of appliance or fuel.  

We always encourage best stove practices and will continue to do our level best to educate new and existing customers and beyond.   

3/ However, the biggest increases in PM2.5 concentrations indoors did not relate to indoor wood or solid-fuel burning but instead were a result of cooking, especially frying, grilling and use of the oven, and particularly when the extraction fan was not used.  

This really provides perspective on the issue of PM 2.5 in the home. A slice of burnt toast or your Sunday lunch can contribute far more than a wood-burning stove.  

 It’s a shame they don’t plaster these findings on a bus or large poster. 

A lack of scientific rigour 

Imprecise methodology  

“The results were compared to modelled wood and solid-fuel burning emissions to identify areas where the measurements match well with predictions or where measurements may provide evidence of solid-fuel burning that were not predicted by the model.” (pg.9 of the LWBP report)  

They do not sufficiently differentiate between the different sources of ‘solid fuel burning’. Data collection relies heavily on estimations and ambient air sampling, offering a blurry picture at best. Traffic, construction, industrial processes and even natural dust all contribute to PM2.5 and cannot reliably be controlled in their methodology. 

(Pg.20 of the LWBP report)

Walking around with modified backpacks does not allow them to distinguish in any way what the source of PM2.5 is in a given area.  

Small sample sizes & poor testing equipment 

One of the major studies often cited, is by Rohit Chakraborty et al, and based on a sample size of just 19 homes that took measurements using, as they admit, “low-cost air quality monitors” (7) 

Manipulated data 

Data is also often twisted and cherry-picked to bolster a blinkered argument. For example, comparing the emission rates between wood stoves and HGVs has caused much unnecessary concern.  

Closer inspection revealed their data excluded brake and engine wear and in fact, just one Euro 6 HGV produces 13 times more PM2.5 emissions than an Ecodesign wood-burning stove over the course of a week’s real-world use. Furthermore, emissions from HGVs are emitted at ground level (nearer head height) while wood smoke is dispersed more safely, higher up via a chimney flue.  

The SIA say, “ The claims are based on simplistic calculations using permitted rates of emission and do not consider either real world use or non-exhaust emissions. Furthermore, these permitted emissions rates rely on vastly differing measurement protocols and techniques. It should also be noted that there are several unreferenced assumptions, and the report does not appear to have been independently peer reviewed.” (8) 

Expert ‘opinion’  

In the bottom left-hand corner of every page of the London Wood Burning Project report you can see the following disclaimer: 

“This report is the independent expert opinion of the author(s)” 

Firstly, anyone can claim to be an expert in whatever they like, however, the key word here is ‘opinion’.  

Well, the SIA has commissioned extensive independent research which casts serious doubt on the estimations and ‘opinions’ provided by anti-woodburners (6). Experts question the methodologies and point out the lack of robust data used to support their dramatic claims.  

We highly encourage you to read this report undertaken by Dr Amanda Lea-Langton, senior lecturer in Bioenergy Engineering at the University of Manchester:  

 https://stoveindustryalliance.com/wp-content/uploads/2022/04/22-04-11-Indoor-air-final-V5-AL.pdf 

 We have listed some of the key findings below: 

-No scientific evidence found for adverse health impacts from exposure to the indoor air typically associated with modern, enclosed wood burning stoves

-No association shown between exposure to indoor wood burning and risk of asthma in developed countries

-Use of modern wood burning stoves may help to improve air quality inside the home due to the natural draught created during wood stove operation that pulls air from the room into the appliance and from outside

-Other sources of particulate matter in the home, such as cooking, can release much higher levels of PM compared to modern, enclosed wood burning stoves, and could therefore havegreater health risk potential

-In one study, oil-based cooking, such as frying food or grilling meat, had peak value PM concentrations significantly higher than the WHO recommended average 24hr exposure limit

-In the same study the Ecodesign wood burning stove indoor air quality averages during operation were below the WHO recommended limits

 The official data (the truth) is good news!

And how about this for good news? The TRUTH is that UK PM 2.5 emissions have been steadily decreasing over the years despite record stove sales (please see the short video above). This is data taken directly from DEFRA and is a scientific and unbiased representation of the air quality in the UK. Whilst there is more we can all do, the evidence is resoundingly positive. 

At the time of writing (11/01/2024) on a very cold winter’s day when wood stove usage would typically be higher, here is the PM2.5 picture for the UK taken, once again, from DEFRA’s official website.  

https://uk-air.defra.gov.uk/forecasting/ 

So, when the anti-woodburners say 17% of emissions. It is 17% of a very low amount in the first place. Then, remember modern wood-burning stoves are just 1-2% of that low amount. 

Modern stoves equal lower emissions with HUGE benefits 

Next time you encounter someone who questions the benefits of modern wood-burning stoves, here is a list you can reel off! 

1/ They can produce heat for sustained periods and are unaffected by external factors such as the weather. 

2/ Allowing them to work in conjunction with wind, solar and other green heating solutions. A stove makes these great technologies more viable – They are not in competition with each other. 

3/ A wood-burning stove is an ideal emergency/low-frequency heat source. 

4/ Wood is a carbon-neutral fuel as it gives off the same amount of carbon whether it is burnt or decays naturally. The carbon released from burning wood is balanced out by the carbon absorbed by the tree during its lifetime. 

5/ Wood fuel can be sourced locally without fracking and deep-sea oil drilling. 

6/ A good quality stove can last many decades and provide an affordable source of heat for low-income households. 

7/ The right to repair. The majority of components used within a Charnwood stove are modular and can be replaced when or if they wear out further extending the life of your stove. 

8/ Charnwood stoves and packaging are fully recyclable. 

9/ There are significant well-being benefits from using a wood-burning stove. Read about the Charnwood wellbeing survey and all the amazing benefits of owning a stove for your wellbeing. 

Building a Collaborative Path Forward 

The wood-burning stove community’s voice in this debate isn’t just about defending an industry; it’s about ensuring a fair and balanced path towards a cleaner and more energy-secure future. Targeting outdated appliances, promoting responsible practices, and encouraging sustainable forestry practices would yield far greater results for all. 

Modern wood-burning stoves offer many benefits beyond warmth. They provide energy independence, encourage mental wellbeing, support rural communities, and help foster sustainable forestry practices. Responsible utilisation of modern wood-burning stoves can absolutely coexist with clean air initiatives, without compromising the environment. 

We are passionate about building on our 50 years of experience leading developments in the industry and producing the most efficient stoves on the market. We understand why people want to reduce PM2.5 emissions even further and we support doing more to achieve this. That is precisely why we continue to invest significantly in technological advances rather than sensationalist marketing campaigns. 

Thank you for reading and please share if this has resonated with you.

Is your stove ready for winter?

charnwoodstoves
03 Jan 2024

Now that the winter is in full swing, and the days are darker and colder, many of us are spending more time indoors.

And when the temperature drops, there’s nothing better than hibernating indoors, warm and snug in front of the stove. However, you must make sure that your stove is ready for the winter months.

We’ve created a helpful guide outlining how you can ensure that your stove is ready for winter.

 

Conduct a thorough stove examination

To make the most of your stove and maximise its longevity, it’s important that you conduct regular maintenance checks to ensure that your wood burning stove remains in sound working order, especially during the colder months of the year.

First and foremost, you should conduct a thorough examination, checking the below elements.

 

Clean out the ash pan

Most people begin their wood burning stove winter maintenance by emptying the ash pan. However, it’s important that you ensure that the stove is cold and remember, you should always wear protective gloves when cleaning your stove.

The ash pan can easily be cleaned out by using a small shovel to take the burnt ash from the bottom of the pan and dispose of it in a metal bucket. As a general rule of thumb, you should never keep warm ash indoors as it can cause a build-up of carbon monoxide. At the same time, all ash should be stored for at least 24 hours outside before it is disposed of.

 

Check all air holes are clear

Next, you should check that all air holes are clear and free from any debris buildup. After all, it’s not uncommon for dust, dirt and other elements to accumulate in your stove during Spring and Summer when it is not used as much or at all.

Clearing all air holes will ensure that a vital flow of oxygen can access your fire, optimising efficiency.

 

Check stove rope

Now you should take the time to check your stove rope, which can be found around the seals of your stove doors. If you do spot any sign of damage, when you are opening and shutting the door it should be addressed straight away, especially if you identify any gaps.

 

Remove any flammable objects

Before you start using your wood burning stove again, it’s important that you remove any

flammable objects from the area around your stove including decorations and combustibles such as plastic, wood-based products, carpet, textiles and upholstery.  You will be amazed at how many flammable household items can end up next to your stove when it is not being used.

Also explore how best to prepare for the winter energy crisis with a wood-burning stove.

 

Test your smoke and carbon monoxide alarms

When the time comes to get your stove ready for Winter, you should also test your smoke and carbon monoxide alarms, as it is vital that these are in sound working order.

 

Start to bring in some seasoned wood into your property

Now it’s time to start stocking up on seasonal wood so that you are good to go! Remember to always store your wood in a dry space.

 

Also explore our main reasons why it is essential to have a wood-burning stove during the winter.

We love December and the magic, tradition and festivities it brings. Nowhere is that magic stronger than in the Cotswolds at Charlie and Josie’s beautifully restored Grade II listed 14th Century home. We recently made our annual pilgrimage to visit them and film roaring log fires and the cosiest of festive decors. We even ended up featuring in Josies’ Vlogmas episode which you can check out below!

Read on for some behind the scenes fun and why a wood stove really brings the Christmas feels!

Fireplace dressing 

There are so many ways to dress a fireplace and we think you’ll agree that Charlie and Josie have achieved an absolutely stunning result! Their attention to detail and bauble strategising was totally worth it. You can’t help but feel in the Christmas spirit in a space like this – Father Christmas will be pleased to visit! 

At the same time as getting into full festive swing, it’s good to consider some ‘Elf and Safety measures’ and we have just the right blog for you!  8 Tips For Wood-Stove Users Over The Holiday Season 

The wood-burning stove lifestyle 

From collecting wood from the store, to building a fire and enjoying the unique bone warming heat that emanates, the process of owning a stove is a delight that puts you back in touch with yourself. 

Charnwood’s rich heritage 

Charnwood is over 50 years old, so despite the fun banter in the video, we can confirm Ced is not a founder, but he is one of the current directors and part of the 3rd generation of family to run the business.

How to Check Firewood Moisture Content

charnwoodstoves
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.

Check out the best firewood to burn chart UK here.

 

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.

Find out our firewood storage suggestions here.

 

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

charnwoodstoves
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.

Find out our commonly asked questions around wood-burning stoves here.

 

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.

Find out how to clean your wood-burning stove here.

 

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.

Explore how to use a wood-burning stove here.

 

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.

Is it Safe to Leave a Wood Stove Burning at Night?

charnwoodstoves
05 Dec 2023

Have you been using your wood-burning stove and are wondering if it is safe to keep burning overnight? Charnwood Stoves explains everything. Read below.

Wood burners and wood-burning stoves can significantly reduce a home’s heating bill making it an attractive alternative to electric, gas and oil heating for many homeowners.

Not only that, but research suggests that installing a log burner can even increase your home’s value by around five per cent. Additionally, a wood-burning stove can be used to heat not just the room it sits within, but the whole house.

For this reason, wood stoves and log burners have become immensely popular. The demand for wood-burning stoves has soared in recent years as households look for affordable ways to keep warm during freezing temperatures and an energy crisis.

Wood stoves can burn for hours providing homeowners with cost-effective and efficient heating solutions. However, many people with newly installed log burners and wood stoves wonder whether it is safe to leave their wood stoves burning at night.

This blog will mention everything you need to know about keeping your wood-burning stove on overnight.

 

Can You Leave Your Wood Stove On?

The safety of your home is of key importance. Leaving a burning fire unattended can be dangerous however, by following some key steps it is possible to keep your wood stove burning to warm your home at night.

 

Limit the Air Getting to the Fire

Once the flames have dampened down, it is important to close your stove’s air events to control and limit the air getting to the fire. Oxygen causes embers to increase in heat and strength causing the fire to burn faster. Charnwood stoves feature a simple, single air control that can be pushed in to slow the the burn to a slumber.

 

Check Your Space

The more space you have around your wood stove, the more effectively it will heat the room and the safer it will be. If there isn’t enough space around the stove for air and heat to circulate, the performance may be hindered.

What’s more, your wood stove burner must also be a suitable distance away from combustible materials, especially when left unattended at night. It is important never to stack logs close to the sides of your stove.

 

Maintain Your Chimney

If you have a wood stove, you need to have your chimney swept at least once a year to prevent the risk of a chimney fire. Soot and creosote will naturally collect in a chimney after using a wood-burning stove. If not regularly cleaned away, this can cause a chimney fire hazard. Regularly maintaining your chimney by having your chimney swept will allow the free passage of combustion gases to prevent carbon monoxide poisoning and chimney fires. Additionally, chimney sweeping will also remove foreign objects from your chimney such as bird nests, cobwebs, and other blockages.

 

Use the Right Wood

Using the right type of seasoned wood and stacking it correctly in your wood stove ensures the fire burns for much longer. Furthermore, continually burning improperly seasoned wood can cause a build-up of creosote deposits in the chimney. This not only affects the performance of the stove but can also lead to dangerous chimney fires.

Some types of wood, such as driftwood, are poisonous and release toxic chemicals into the air when burnt. This is another reason why you should always choose the right wood for your wood-burning stove carefully.

 

Explore the best firewood to burn in the UK.

 

Key Points to Take into Consideration

The key points to take into consideration when leaving a wood stove to burn at night, include:

• Are the air vents closed to control and limit air that can get to the fire?

• Are all combustible materials, such as paper and candles, placed within a safe distance of the wood stove?

• Does your chimney get regularly swept? Is there any risk of a chimney fire?

• Are you burning the right type of wood in your wood stove?

01 Dec 2023

We’re proud to present the Cranmore: a classic new wood burning stove from Charnwood. While it may be traditional in style it uses the very latest in clean burn technology. The Cranmore draws inspiration from the Regency era with a single framed glass door and archetypal detailing. The stoves pleasing proportions make it well suited to a traditional fireplace and with its large picture window and mesmerising flame pattern it is an ideal replacement for an open fire.

Timeless style, exquisite detailing and built to last a lifetime

The best of British

The Cranmore is British made with British materials, using the latest technology that draws on Charnwood’s 50 years of expertise. It is available in a range of colours and features a firm close, cool-to-touch, handle for safe and easy reloading. It is incredibly simple to operate with one single air control and features a sliding firebed for clean and easy ash removal.

The Cranmore 5 has a narrower portrait window than the 7 but still provides a punchy 5kw output

Available as 5 or 7kW models, the Cranmore uses our clean-burn BLU technology and is exceptionally efficient, with a level 5 clearSkies rating. The comparison table below is a useful tool; however we recommend speaking with your Charnwood supplier to help you decide which stove is most suited to your space.

The perfect open fire replacement

With rules around Eco Design Ready stoves coming into force in 2022 and the potential for further regulation, the Cranmore is an ideal and timely choice. It offers the wonderful ambience and flame picture associated with open fires, while exceeding all minimum criteria for Eco Design Ready status.

The difference between an open fire and the Cranmore in terms of its efficiency and eco-credentials shouldn’t be understated. The Cranmore produces a far more efficient burn and reduces PM emissions by 90%. Added to Charnwood’s policy of caring for the environment, in all aspects of the business, means a Cranmore stove is an environmentally sound heating solution you can be proud of.

Victorian, Georgian, and Regency period properties all provide a perfect backdrop for the traditional aesthetic of the Cranmore. The elegant and timeless design blended with the latest technology makes the Charnwood Cranmore nothing short of a modern classic.

And after the earthquake a fire; but the LORD was not in the fire: and after the fire a still small voice.And it was so, when Elijah heard it, that he wrapped his face in his mantle, and went out, and stood in the entering in of the cave. And, behold, there came a voice unto him, and said, What doest thou here, Elijah? – Kings 19 verses 12-13

The first shiver of Autumn, brings to us thoughts of roaring fires, cosy layers, soft blankets and warming food. Though with the drawing in of the nights and the reduced length of daylight, we increase our time for contemplation and the opportunity to hear that still small voice within us. We live in a time of rapidly progressing AI, which some fear will render much of all work obsolete. In such a scenario, many of us would have to find meaning elsewhere. Regardless of whether our lives are reimagined by AI, a human search for meaning exists, a humane search for empathy and connection. The most independent of us are not immune to feelings of loneliness and a requirement for warmth that no matter how clever the robot, it cannot be surpassed by what tactility offers.

One simple reach towards feeling connection can be found in the simple daily need for nourishment. There are so many off the shelf prepackaged solutions for our ‘busy lives’, that tie in with the materialistic goals of efficiency and valuable results. Though it is in the very act of cooking and sharing food, where we can find the time for a moment to connect and be entirely present with ourselves and others. As winter draws closer, we may wake up feeling uninspired by the rain lashing at our window, and the daily news grind of the troubles that face us both in our own communities and together as a planet. The act of being nourished and nourishing others holds a sacred place; such a basic act comprises a rare, untarnished purity, like the simple comforting sound of a purring cat. The process of preparing, cooking, and laying the table gives us the opportunity to listen to that still small voice which can be so hard to hear within us, in the midst of burgeoning communication channels that keep us distracted.

The journey inwards brings us solace against the chill of the elements and brooding skies. We become concentrated on our homes as a solace from the hibernation of the sun and look forward to the thought of lighting a fire, playing some music and enjoying the pleasure of comfort cooking. We think of tucking into slow cooked stews, silken soups and puddings that invoke the nostalgia of childhood such as old school rice pudding, or a constantly renewing stack of pancakes. As the song by Spike Jones goes, “Pack up your troubles in your old kit bag, And smile, smile, smile. Don’t let your joy and laughter hear the snag…”

In the essay ‘A Purple Future’, Daniel Pinchbeck speaks of how we have lost the knowledge of ancient and indigenous cultures, of our connectivity with one another. Pinchbeck suggests this is, ‘an underlying consciousness that is indivisible, instinctive, timeless and spaceless and without boundary.’ We have instead turned to a way of living that quantifies everything by measurable value and outcomes. It is of course hard to sometimes reach into this thought process, when we are faced with the rising costs of living and an uncertainty of basic material requirements. Though as with all human progress, our fears have become so strong that they curtail the freedom to be creative as we try to grip onto certainty. We can see as a simple observation that with young children, who are unencumbered with anything but the moment that joy is always present and experimentation paramount as they learn about the world around them.

The lead into winter and the early nights drawing in some way gives us this sacrosanct time in which to pause, to cook that slow stew and undertake simple acts such as lighting a fire. These moments allow us to open ourselves to the silent possibilities and creativity that arise from ‘hunkering in’ so we may begin to see new shafts of light as we navigate our way through the darkness.

New Report Reveals Charnwood C-Five Stove Helps Improve Indoor Air Quality!

charnwoodstoves
28 Nov 2023

In the ongoing debate over air quality and PM2.5 emissions, modern wood-burning stoves often face unfair criticism. The root of the issue lies in the unfortunate lumping together of modern ultra-efficient stoves with their vastly more polluting counterparts—open fires, outdoor bonfires and old, poorly maintained stoves. Today, we turn our attention to the latest report, released by the Environmental Research Group. 

Anti-woodburning groups have previously drawn on questionable data often not recognising the crucial distinctions between various types of wood-burning. However, there is a glimmer of progress, as this latest report at least acknowledges some of the benefits of ultra-efficient stoves and that ClearSkies 5 Stoves can in fact improve indoor and outdoor air quality. This is a step in the right direction.   

Key Findings from the London Wood-Burning Project: 

On page 71 of the 127-page report, we find the page titled Key Findings. Below are the 4 crucial pieces of information from this page: 

1/ Use of the clearSkies Level5 stove demonstrated some benefits for indoor air quality. Indoor PM2.5 did not increase when adding fuel to the stove once lit… At times there was actually a decrease in indoor concentrations of PM2.5 when adding fuel. 

As we have long pointed out, a properly functioning wood stove draws particulates out of the room and up the flue, helping improve air quality and ventilation in the home. The stove used in this study was our Charnwood C-Five. 

2/ Increases in pollutant concentrations may be more affected by participant technique or specific airflow characteristics of an individual appliance, rather than to the type of appliance or fuel. 

We always encourage best stove practices and will continue to do our level best to educate new and existing customers and beyond.  

3/ However, the biggest increases in PM2.5 concentrations indoors did not relate to indoor wood or solid-fuel burning but instead were a result of cooking, especially frying, grilling and use of the oven, and particularly when the extraction fan was not used. 

Again, we have tried to communicate this fact for a long time, as it really provides perspective on the issue of PM 2.5 in the home. A slice of burnt toast or your Sunday lunch can contribute far more than a wood-burning stove. 

4/ The PM2.5 increase measured outdoors, due to the non-DEFRA exempt stove, was double the increase due to the clearSkies Level 5 stove. 50 μg m-3 and approx. 25 μg m-3 

The methodology used to gather this data from the environment, again, can not adequately separate the different sources of PM2.5 in the tested areas. It is subject to error from many environmental factors, such as road traffic, construction, manufacturing, and other industrial processes. 

However, this data does still accept that a modern ClearSkies 5 stove significantly reduces emissions. We have rigorously tested all Charnwood stoves and when ensuring best stove practices and using seasoned wood with a moisture content of less than 20%, emissions can be reduced by up to 90% in comparison with an open fire. This provides an exceptionally clean burn! 

Differentiating Wood-Burning Practices: 

It is essential to differentiate between various forms of wood-burning. The UK government’s 2020 figures highlight that Ecodesign-compliant stoves contribute only 1-2% to PM2.5 emissions, a fraction compared to other sources. ClearSkies Level 5 stoves, surpass Ecodesign standards, offering a further reduction in emissions by up to 30%! 

This is where the anti-wood-burning stove movement has gotten it so wrong in the past. By not differentiating accurately between different wood-burning practices they have missed the opportunity to really help reduce PM 2.5 emissions with a solution that has been proven to work – modern ultra-efficient stoves. 

In London 70% of wood burning still occurs on open fires. If people were widely encouraged to switch to one of the many modern and efficient wood burning stoves available, it would massively reduce urban PM 2.5 emissions. The emissions of 70% of London Wood burning could be reduced by 90%! 

Wood-Burning Stove’s Co-Heating Future  

Heat pumps, solar and wind energy, have positive qualities, but are simply not sufficient to meet our home heating needs on their own. This is particularly true for the vast amount of older housing stock across the UK. Wood-burning stoves can increase the uptake of other renewables by providing energy security and filling the gaps in power. 

Below is a link to an article which comprehensively explains why modern wood-burning stoves will be an essential heating solution long into the future. 

Wood-Burning Stove’s Co-Heating Future (A Nuanced Look At PM 2.5 Emissions) 

____________ 

With gas and electricity prices set to increase even further in January 2024, we need all sides of the debate to work towards a more informed and positive dialogue. For our part, we continue to lead the industry in creating the most efficient stoves on the market. We are investing heavily to continually improve and are passionate about providing people with energy security and the many other benefits offered by wood-burning stoves. 

The SIA Examine the Latest (Misleading) Wood-Burning Stove Study

charnwoodstoves
17 Nov 2023

The Stove Industry Alliance (SIA) has carefully examined a recent study by Global Action Plan/Impact on Urban Health, titled “Relight my fire? Investigating the true cost of wood-burning stoves.” In this blog, we will present some of the key insights and considerations revealed by the SIA that address the misleading conclusions made. 

Study Methodology Critique 

The SIA raises important questions regarding the methodology used in the study. Specifically, the model scenarios seem to artificially inflate the costs associated with wood-burning stoves while decreasing costs related to Air Source Heat Pumps (ASHP). The SIA points out discrepancies in cost consideration, installation assumptions, and the efficiency impact of heating system distribution. 

Here are just two of the key points raised which show why it is impossible to draw accurate conclusions from the data set: 

Model B “includes the cost of purchasing the item (stove) and installation, while all options include maintenance and replacement costs.” The SIA questions why the purchase and installation costs have been factored in for the stove led heating in Model B, as they have not been factored in for the gas boiler led heating, Model A? 

Model E “Newly installed Air Source Heat Pump (ASHP) providing 100% of heat” underestimates the actual running costs of the ASHP in the reference dwelling used (a Victorian mid-terrace of single skin, uninsulated solid brick construction). Heat pumps are not suitable for use in badly insulated housing stock; they will not run optimally in these conditions and therefore won’t give a 3.5 seasonal CoP which the report uses to reach its conclusions.  

Appliance Efficiency 

When evaluating cost-effectiveness, appliance efficiency is a highly significant variable, and is not accurately reflected in the study. Since January 1, 2022, all solid fuel stoves have had to adhere to Ecodesign Regulations and ensure a minimum efficiency of 75%. Many of our stoves surpass this requirement, with tested efficiencies exceeding well beyond 80%, which is comparable to the most efficient gas room heaters in peak condition. It is also important to consider that wood-stoves offer individuals better localised space heating, meaning they allow you to heat the space you need without wasting heat on empty rooms. This is a key part of many people’s heating strategy and this flexibility also facilitates off-grid low-carbon sustainable living. 

Comparative Fuel Costs 

The SIA references data from various sources, including Nottingham Energy Partnership, to provide readers with a comprehensive view of comparative costs per kWh for different heating fuels. As of October 2023, the price per kWh for an ASHP is 12.37p, kiln-dried logs at 11.18p, mains gas at 8.64p, and electricity at 33.40p. It should be noted that, between November 2022 and June 2023, kiln-dried wood logs were more cost-effective than mains gas per kWh. 

This points to another key reason people choose wood-burning stoves – energy security. It is still fresh in everyone’s minds how susceptible gas and electricity prices are to spiking at a moment’s notice because of global issues. Sustainable sources of wood are available locally and provide a vital shield against the next crisis. 

We invite you to read our blog on why people are choosing wood-burning stoves to better understand the many factors that were missed in this study. 

SIA’s Recommendations: 

We are fully aligned with the SIA on the recommendations for those considering or currently using wood-burning stoves: 

-Choose an Ecodesign compliant, sustainable, solid fuel stove. 

-Upgrade from an open fire or older stove to reduce emissions significantly. 

-Ensure your stove is Defra exempt if you live in a Smoke Control Area. 

-Seek guidance from local SIA Retail Group members for the right stove size and installation. 

-Have your stove fitted by a qualified professional (HETAS or OFTEC registered). 

-Use quality fuel, ensuring wood logs have a moisture content at or below 20%. 

-Regularly service and sweep your chimney for optimal stove performance.
