Why Dry Firewood?

  • Most people who live with woodfires know that their firewood needs to be dry. But it is more than that - I was shocked when I calculated how much heat is lost boiling off the sap, even from a normal seasoned ready-to-burn log. The physics of latent heat is almost magical - and knowing this opens up a new world of understanding for those of us who live with wood heating. Dry logs burn hotter and cleaner, this is becoming more important as attention on emissions grows - especially of smoke and fine particulate matter (PM2.5) from wood and coal, open fires and stoves. This is not just important in smoke controlled areas - it is for all of us. Wood is a true renewable, one we should be proud to use - as long as it is harvested sustainably and burned efficiently. This wonderful and ancient heating fuel does not release fossilised carbon, nor create radio-active waste!

    Good advice… summed up appropriately in the Latent Heat section of your book “Trying to burn unseasoned wood is like trying to get warm in wet clothes”

    Thank you very much.

    You really put the moisture content of our firewood into perspective. Thanks for another great video!

  • @wayneberry8703

    Well said, and I totally agree with your reasoning with damp or wet timber.

    Thank you for making this visual video.

    Couldent agree more

  • @MegaJamiegreen

    really good info thanks

    20% is still great for wood chunks that you want to use for smoking your food. Thanks for another very informative video. I just subscribed! Hello from Manitoba, Cadada

    There's a reason why nobody talks about this: people just don't understand it enough to see its importance. I know, that sounds mean and cynical. But it also happens to the case: simply put, we're just naturally bad at interpreting statistical information. That's why there are such things as casinos, adjustable-rate loans, and the lottery. The idea that small amounts gather seems intuitively obvious to us, yet, in practice, it somehow still remains ever beyond our conceptual grasp.

    Hello fella, just found your channel and absolutely love and appreciate your knowledge and the fact your from Somerset like me. Books on my Christmas list 👍 Thankyou

    Wow very graphic and really gets the message across. I knew it was good to have dry wood,now I understand why and it saves money and makes my wood last longer.Small wood store. Please do the overnight burn video. I have not heard of the put damp wood on. Thanks for kitchen physics! The OU would be proud.

    Thank you for such an informative video. I have never seen anyone else explain it in this way, and show how much water that 20% moisture equates too. Simply fascinating.

    We own a young small forest and sell off most of the thinnings as firewood. Currently we're thinning mostly softwood. Customers are so hung up on hardwood vs softwood when the should pay far more attention to the moisture content over the type of wood. Of course most very dry hardwood is superior but many sellers often don't wait long enough before selling it.

    Well done Vince. A great video!

    Appreciated the physics - if you wanted to continue how about breaking down the density of woods - we have heated debates (pun) over buying oak or ash or birch as a example as that’s generally what’s kiln dried commercially available I want oak and my wife is happy with ash.

  • @paulfisher7911

    so why was the garages and shops up till 2 yrs ago selling wet wood and coal oh yes for the weight so they could make more profit . glad your showing the importance of dry wood

  • @teatowel11

    I saw a video of a guy using latent heat extend the warm of his fire one.

    Great video, looking forward to the next one! It's staggering to think that at todays wood prices how much of your money can be lost if the wood is not sufficiently dry. Thankfully I use a lot of chunky untreated birch and oak joiners offcuts at around 10% moisture so hopefully getting maximum heat for my money!

    thank you for another really informative video we love it when you launch a new one. Big thank you for them all
