Using a wood-burning stove is a very safe, sustainable and cost-effective way to heat your home and create a warm and cosy ambience. It is, however, important to consider the type and condition of the wood you burn as this can significantly impact the positive benefits of your fire. One important aspect to consider is whether the wood is sufficiently dry enough or is it still too damp to burn and does it require more seasoning (drying).
Why is burning damp wood in your home a problem?
More smoke and condensation can cause residue buildup
When you burn damp or wet wood, it produces much more smoke that condenses onto the cooler sides of the flue or chimney. This can lead to creosote residue build-up which is highly flammable and increases the risk of chimney fires and damage to your stove and flue.
Damp wood results in poor-quality fires
Damp wood, which is wood with a moisture level of over 20%, doesn’t burn efficiently. The high moisture content prevents the wood from reaching the high temperatures needed for adequate combustion. As a result, the fire will produce far more smoke and significantly less heat which is highly inefficient. The excess smoke and particulates can also contribute to indoor and outdoor air pollution which is something we can all agree we want to minimise.
The good news: A Charnwood Clearskies 5 rated stove using well-seasoned or kiln-dried wood drastically reduces any emissions and maximises fuel efficiency – ultra-clean burning that saves you money on your fuel bill!

Increased maintenance of stove glass required
The excessive smoke and soot produced by burning damp wood can lead to an increased accumulation of residue on the stove glass. This can be a real pain to clean and there is also a risk of scratching the glass surface in the process if you’re not careful. As well as stopping you from being able to fully enjoy the aesthetic appeal of your stove, it can also impede your ability to monitor and respond to the fire and ensure it is burning optimally.

It is less sustainable and costs you more money
Burning damp wood is much less efficient which means you end up burning more wood for less heat. That means more trees are required and more expensive fuel bills.
The lower combustion rate of wet wood produces more pollutants than that of dry wood releasing higher levels of particulate matter (PM10 and PM2.5) carbon monoxide and volatile organic compounds (VOCs) into the atmosphere.
More good news: By burning dry wood with a modern stove, you can reduce your carbon footprint and significantly minimise the environmental impact of your fires. It is important to remember that burning dry wood on an Ecodesign-compliant stove accounts for less than 0.3% of total UK PM2.5 emissions – so be mindful of what you read in the media!

Is burning wet wood ever worth it?
Beyond an extreme situation where there are no other options, the short answer is no. The safety issues, inefficiency, potential damage to your stove and the environmental impacts far outweigh any potential convenience. It’s always better to allow your wood to season thoroughly before burning or you can purchase kiln-dried wood which is readily available – remember to look for the Ready To Burn logo!
Properly seasoned wood will have a moisture content of less than 20%, which you can check with a moisture meter. This will ensure a cleaner, hotter and safer fire to enjoy.
