The wood for this stove by Michiel Martens and Roel de Boer needn't be chopped as whole tree trunks can be fed into it (+ slideshow).

Dutch designers Michiel Martens and Roel de Boer collaborated to create the wood-burning Spruce Stove, which uses the entire length of a log to heat a room.

"By gently pushing the trunk inwards during the burning process the experience subtly becomes a natural and informal time-indicator which holds the promise for long, warm and cosy evenings at the fireplace," said the designers.

The stove consists of a circular horizontal drum in which the fire is lit. An aperture at the end closes around the tree, accommodating logs of different sizes.

Serrated teeth at the top of a stand clamp the wood at one end, which is moved on wheels towards the flames as the log burns.

Spruce Stove was shown at Dutch Design Week 2013, which also featured projects such as Dave Hakkens' Precious Plastic recycling machines and Evelien Crooy's ink made from insects.

Here is some more information from the designers:


A new approach of burning wood, you can feed this stove a complete tree trunk. The opening is a diaphragm and encloses seamless around the tree.

During the firing you need to gently push the trunk inwards into the stove until the last part disappears. The fire is in directly connected to the length of the tree log. The longer it is, the more you can enjoy the comfortable heat of the stove.

The Spruce Stove arose from collaboration between Roel de Boer and Michiel Martens.

Two young individual designers both with a personal handwriting but carrying the same interests and curious conceptions.

  • The Pope

    What a load of impractical, student drivel! Great design is timeless. Good design works. Therefore this is a waste of time, effort, space, materials etc.

    • annalisedyy264

      Lack of knowledge helps a concept, but spoils a design!

  • hudley

    Nice concept but the moisture content of a whole log may cause burning issues.

    • pipo

      There will probably be boiling hot moisture spewing out the backside of the log.

  • Bob

    Just one question. In case for one reason or another nobody pushes the burning trunk in. Does your house burn down? Or does everyone just die of CO poisoning? Is this the idea?

  • Cor

    Lack of knowledge helps a concept, but spoils a design!

  • pipo

    “Fire Hazard” a new stove by Michiel Martens and Roel de Boer. Don’t turn you back on this stove; it’ll burn down your house.

  • Gustav

    You make wood fit for burning by reducing its water content – usually by leaving it for a period of time and by cutting the wood to shorter lengths, which opens for the atmosphere to increase evaporation from the wood. Drying up a whole trunk will take ages, they are probably gonna hang on that wall for years…

  • Steve

    If this is why Dutch Design Week is two years ahead of Milan? I think I will stick to Milan.

  • metis1

    You wonder how it’s initially lit. A match and a newspaper is generally not going to ignite an entire tree.

    • polo

      Well, the same for a log cut in a 30cm length!

  • ilike

    Well you all clearly miss a touch of adventure and insight. How can you be sure it doesn’t work? I’ve seen it burn in Milan, and it does it majestically!
    So, you whiners, do stick with your boring central heating. This stove is clearly not made fore you.

      Thank you ilike! As usual no shortage of boring whiners presuming failure. When I was a kid we used to burn the christmas tree by sticking it in the fireplace and slowly stuffing it in as it burned. Was that totally dangerous? Yes. (My parents are crazy.) But we didn’t die, boiling sap didn’t spew out of the trunk, the house didn’t burn down, a grand time was had by all. And this plan is a darn sight safer than that.

      • pipo

        If you have ever felled some trees and made a campfire with fresh logs, you’ll know that deciduous trees contain a lot of moisture unlike pine. There will be sap boiling out of the trunk and it will take ages for the whole log to dry.

        I guess if your sense of great adventure comes from burning a Christmas tree in your stove, this product is just right for you.

  • amsam

    I said “grand time” not “great adventure,” and I’ll stick by that assessment.

      Interesting project. Curious how it manages ash?
