Dry wood vs green wood: how to recognize good firewood

Good firewood is sufficiently dry wood: it burns more cleanly, heats better and doesn't load your stove, boiler or chimney with unnecessary smoke and deposits.

When you buy firewood, one of the most important questions is not just "what species is it?", but also "how dry is it?". Beech, oak and hornbeam are excellent hardwoods for heating — we've written a comparison between them here — but if they're green or poorly stored, they won't deliver the expected output. The difference between a winter with good fires and one with smoke, sooty windows and double the consumption comes down, most of the time, to the wood's moisture.

In short:

• Green wood loses a significant part of its heat evaporating the water inside it — you burn more to get the same comfort.
• You recognize dry wood by its weight, the cracks at the ends, the "dry" sound when struck and the bark that peels off easily.
• The most reliable test remains the moisture meter; as a guideline, wood ready to burn should be under about 20% moisture.
• Green wood is not a problem if you buy it in good time and store it correctly for the following season.
• The real problem is green wood sold as "ready to burn" — which is why the questions you ask before ordering matter.

What green wood means

Green wood is freshly cut or insufficiently dried wood. It's usually heavy, cold to the touch, has lighter or downright wet ends and may have a strong sap smell. When you put it on the fire, part of the energy is lost evaporating the water in the wood, before the wood even starts to burn efficiently.

The result for you is simple and immediately visible: you burn more wood, you get more smoke, the fire is harder to start and the heat comes more slowly. On top of that, damp, smoldering combustion deposits soot and tar on the chimney walls — meaning a chimney that needs cleaning more often and an additional risk that no one wants in the middle of the season.

A detail that many learn too late: green wood weighs noticeably more than the same volume of dry wood. If you pay for wood "by sight" and it's green, you're also paying for the water in it — and water doesn't heat.

How to recognize dry wood without instruments

There are a few practical signs you can check directly at delivery, in a few minutes:

• The weight. Dry wood is noticeably lighter than green wood of the same size and species. Pick up a piece — you can feel the difference.
• The ends. Dry wood often has small radial cracks at the ends, like rays. Wet, dark ends or ends with visible sap indicate green wood.
• The sound. Knock two pieces together: dry wood "rings" clear and dry, almost like a baseball bat. Green wood makes a muffled, dull sound.
• The bark. On dry wood, the bark starts to come off more easily or has already fallen off in places. On green wood, the bark is firmly attached.
• The interior. Ask for a piece to be split on the spot: the core should not look cold, wet or darker than the outside.

None of these signs is enough on its own, but together they give you an accurate picture. For large quantities, especially for a boiler, it's worth checking several split pieces from different parts of the load, not just from the top.

The reliable test: the moisture meter

The most reliable test remains measuring the moisture with a moisture meter — a simple and inexpensive device with two electrodes that you push into the wood. Always measure on a freshly split surface, inside the piece, not on the outside: the outside dries first and can be misleading.

As a guideline, wood ready to burn should be under about 20% moisture. Freshly cut wood starts from much higher values and needs, depending on species, splitting and storage conditions, one to two years to reach the right level. Oak, for example, dries more slowly than beech — yet another reason to ask not only about the species, but also about how long ago the wood was cut.

Dry wood doesn't mean old, degraded wood

A common confusion: "dry" doesn't mean any old wood that has sat in the yard for years. Properly dried wood should not be rotten, moldy or full of dirt. Good wood has a firm texture, a natural color and a clean wood smell. If it's crumbly, has soft spots, mold patches or a stale smell, we're no longer talking about proper drying, but about poor storage — and its heating value has suffered.

For serious heating, in stoves, boilers and fireplaces, the complete combination matters: hardwood, cut to the right size for your firebox, properly dried, stored with good airflow and delivered with clear documents — we've written separately about the documents you should receive at delivery.

When it's worth buying green wood

Green wood is not the enemy — sold correctly, as green wood, it can even be a smart choice. It makes sense if you buy it in good time, in spring or summer, split it (or ask for it ready-split) and store it correctly for the following season or even for two years ahead. Bought off-season, wood is easier to find, delivery is more relaxed, and you have full control over the drying.

In practice, many well-organized households work exactly this way: this winter they burn the wood bought last year, while the wood bought now dries quietly in the stack. How to arrange it so it dries well — what you lift it off the ground with, what you cover it with, where you place it in the yard — we've detailed in our storage guide.

The problem only arises when green wood is sold as ready-to-burn wood, at the price of dry wood. That's why it's worth knowing the signs above and asking the right questions beforehand.

What to ask before you order

So that there are no surprises at delivery, clarify by phone or message:

• What species is the wood (beech, oak, hornbeam, mixed)?
• Is it freshly cut or prepared for burning?
• What size is it cut and split to — does it fit your firebox?
• How is the quantity measured: in solid cubic meters or in ster? The difference is far from small — we've explained it here.
• Does the price include delivery? Up to where?
• Do you receive an invoice and origin documents for the transport?

A serious supplier answers all of these directly, without dodging. If you get vague answers to simple questions, that's a signal.
