Fire wood burning wood

All you need to know about firewood.

Why should we burn dry firewood?

Nic says: There still seems to be a misunderstanding about the importance of burning dry wood. It seems that when it comes to fuelling our car, or buying oil or gas for the home, it is simple to buy a set standard of fuel that we can trust. 

However, when it comes to firewood, historically there has been no set standard, just the knowledge by many that you need to burn ‘seasoned wood’. But what does that mean? This does not give specific information, but it is supposed to mean ‘dry wood’. The correct moisture content for firewood that is ready to burn is below 20% moisture content and the benefits of this are massive. Not only will you get far more heat output, you will avoid blackening of the stove glass and minimal soot build up in the chimney or flue. Finally, because you get more heat output, you will actually use less fuel.

If wood is too wet, it will not only be difficult to light, but it will also struggle to burn, give very little heat output and most certainly tar up the flue very quickly. Ultimately this could lead to a chimney fire, so it is important to burn sufficiently dried firewood.

What does it mean to be ‘sustainably sourced’?

Nic says: Quite simply the best way to ensure your firewood is sustainably sourced is to buy locally sourced British wood as this is tightly controlled by the forestry commission. All UK woodland has a management plan in operation, so for any felling to take place, a licence is required. This means no British woodland will ever be clear felled unless in extreme circumstance such as disease, but nevertheless, plantations will always be replanted – those are the regulations. 

What is the Ready to Burn Scheme?

Nic says: This was set up by HETAS about 2 years ago and provides suppliers and customers with a recognisable ‘brand’ and logo that guarantees that the wood you are buying is below 20% moisture content so, ‘ready to burn’. However, make sure your ‘Ready to Burn’ logs are stored under cover to avoid any unnecessary increase in moisture content.

Look out for the logo on packaging and at your local retailer and once again, if in doubt ask the retailer. It does not presently cover anything else, so if you want to ensure your wood is British, then look out for the Grown in Britain logo.

Handy hints for efficient burning

Following on from this weeks posts about burning your stove correctly, here’s a few basic tips to help you avoid bad burning.

• Read your stove handbook thoroughly (honestly, you’d be surprised)
• Learn how to effectively control your stove ( eg the difference between primary and secondary air controls, if your stove has them)
• Know what the recommended fuel load is, so you don’t ever over fire the stove.
• Never burn wet wood – always look for the Ready to Burn sign.
• Don’t skimp on kindling – this quickly creates flames and the vital heat that produces an efficient updraft.
• Use smaller logs at the start until the fire is established before you begin to add regular sized logs.
• Don’t reduce the combustion air supply until all of the log surfaces are burning (they should look grey).
• When you eventually turn your stove down, make sure it’s not to the point where you can see smoke rising off the fuel.
• Never add regular or other sized logs to embers as these big, cold logs will quickly reduce the fire chamber temperature and create smoke.
• When refuelling sometimes it’s better to add kindling and effectively start again.
• Always provide the maximum amount of combustion air until all of the new log’s surfaces are burning.

EU Ecodesign is just around the corner… what does it mean for log burners / multi-fuel Stoves?

Ecodesign Air Quality Benefits

As well as Carbon Monoxide (CO), now emissions of Nitrogen Oxides (NOx), Organic Gaseous Carbon (OGC) and Particulate Matter (PM), which also contribute to climate change and air quality issues, will be tested.

The EU Ecodesign limits for these emissions are actually very difficult for new stoves to achieve and many old stoves, particularly all-cast iron stoves, simply won’t come close enough to passing them to warrant manufacturers putting them through the expensive tests. Sadly, this will also herald the end of traditional high-output boiler stoves. Very old stoves, inefficient open fires, burning deadly wet wood and smoky old coal are amongst the biggest pollution threats to cleaner air.

This is definitely not the case for environmentally friendly Ecodesign stoves!

Be kind to the environment

Burn bright and burn right

There are a couple of important things that today’s environmentally-conscious home owner needs to know about getting the best out of their stove: How not to waste fuel and how to avoid producing smoke which damages our air quality.

Wood logs are virtually carbon neutral and when they’re fully seasoned and burned correctly in a modern stove, they will also produce significantly less particulate matter (PM).

Smoke indicates inefficient burning and the main difference between it and flame is temperature. When lighting a fire you need to get the temperature inside the fire chamber as high as possible and as quickly as possible.

This is critical when it comes to creating a good ‘draw’ within the flue system, especially when it is particularly cold outside. The higher the temperature, the less smoke is produced and more of the harmful particulates are burned away, so less of it goes into the air.

Chimney sweeping and stove maintenance

Maintenance is key to an effective log burning stove / wood burning stove / multi fuel stove

An effective stove is a clean stove… said nobody ever! But it is true. Efficient burning requires the correct amount of air and fuel. Your chimney creates the ‘draw’ that sucks air into your fire. So if your chimney is blocked or the draw is reduced by soot and tar then your fire ain’t going to get enough air to burn efficiently.

Chimney sweeping

You should get your chimney swept twice a year in order to ensure appropriate ‘draw’ is achieved. But, much more important than this, a clean chimney is a safe chimney. Dirty, sooty and tarred chimneys will eventually lead to a chimney fire. And that’s not going to be fun at all.

We sweep chimneys and service log burners and stoves. We also install wood burners / log burners / multi fuel stoves.
