How to choose wood briquettes?

Don’t worry – it’s easier than you think! Our wood briquette guide will help you become a wood fuel expert in no time.

Koka briketes Wood briquettes and heat logs are interchangeable terms. They both describe a product made of wood by-products. These can be sawdust, wood chips or wood flour, using extreme pressure to form a block or log shape.
Different briquettes have different combustion properties, making some more suitable for certain stages in your fire’s life.
Some are great for lighting a fire; others are ideal for a nice hot flame during the day and others are designed to burn slowly at night.

Each stove is different depending on airflow, flue configuration and especially weather conditions. We only learned that there is no such thing as one “best” briquette for everyone. The best option is to try a few and see what suits you. Our sample kits and ready mixed pallets are perfect for this.

Generally speaking, a single good quality compressed log is equivalent to three or four traditional logs.

What makes a good briquette?

Compression: is the briquette dusty or brittle?

Compression refers to the pressure with which the wood is briquetted. High compression is better – these briquettes are denser and less dusty.

Low-quality machines, operating with a low degree of compression, produce cheap and dusty briquettes. We avoid them because they often deter people from smoking briquettes.

High-quality briquettes are manufactured using large, expensive machines working with very high forces to achieve a density of over 1000 kg / m3. The result is briquettes with a high calorific value that keep their shape and burn for a long time.

Caloric value: how much heat can it generate?

We compare the calorific value in terms of kilowatt-hours per ton (kWh / ton) as this allows easy comparison with other heating fuels such as coal, gas and oil.

As a guide, traditional logs have a calorific value of around 4,100 kWh / ton (depending on the humidity and tree species), while good quality briquettes have a calorific value of 4,800 to 5,000 kWh / ton, depending on the density and species of trees. (Note: 5500 kWh / ton is the same as 5.5 kWh / kg.)

The calorific value measures the heat output.

Ash content: How much ash will it produce when burned?

This is how much ash remains in the ash pan when extinguishing the fire. Virgin wood briquettes that have the bark removed produce significantly less ash than traditional logs. Some of our briquettes contain as little as 0.28% ash. For comparison, Bracken briquettes contain 4-7% ash.

However, some of the bark in the mix can increase the caloric value, and a large amount of bark in the briquette can help keep the furnace warm for longer periods, and even overnight. Our pure RUF Bark bricks contain approximately 4% ash and can burn for up to 12 hours. The bark contains more silica than clean wood, which creates ash.

Pure wood-burning ash is an excellent source of potash in your garden, so it can be safely added to the compost bin. Just make sure it’s completely cold first!

Moisture: how much water is in the briquette?

Wood briquettes generally have a water content (moisture content) of less than 10%. Most high-quality briquettes are dried to less than 6%.

By comparison, traditional logs are considered smokable when less than 20% and most winter-bought logs have around 30% moisture content. That’s a lot of water to evaporate and a very expensive way to buy it.

In general, the drier the better. The purpose of combustion is to generate heat, not to remove moisture, before the fuel produces heat. However, dry but poorly compacted briquettes burn too quickly. While they are often cheap, they are of low value compared to densely compacted but necessarily more expensive briquettes.

Extras: what else is in it?

The answer to that should always be “nothing.”

None of our briquettes contains additives (facilitating combustion) or binders (facilitating compaction). All our briquettes are bonded by the natural lignin released from the wood under the influence of intense compaction pressure.

Remember: if the wood content is dry enough, you do not need combustion additives. And if the heat log is tightly compressed, there is no need to add a binder. So a good quality briquette will not have and will not need any additives.

Product Standards: Are there any industry standards I should be looking for?

The highest quality briquettes are produced in accordance with European standards. They inform that the manufacturer complies with European standards for the composition, traceability, environmental sustainability and quality of the product. The standards to look for are ÖNORM M7135 (Austria) or DIN51731 (Germany). The equivalents of the EU and British standards are BS EN 15210-1 2009 and BS EN 15210-2 2010.

However, there are many briquettes of excellent quality that are not certified as the certification process is cumbersome and costly. Responsible manufacturers will always be able to provide the information we describe above, regardless of their certification.

Package size:

While weight is not a foolproof way to purchase traditional logs, the consistency of the briquettes means knowing the price per kilo is really helpful.

Most packages weigh around 10 kg, but some packages are 5 kg, 12 kg, 15 kg, and others 20 kg. Of course, this should be taken into account when comparing prices between products. That is why we always mention “price per kilo” to facilitate comparison.

It may seem obvious, but don’t assume that more is better (I often have to comment “Ah, but there are four in this package and five in this package”); four briquettes in a 10 kg pack or twelve briquettes in a 10 kg pack; it’s the same energy, just four 2.5 kg each should last more than ten 1 kg each.

Pallet Size:

Again, while most pallets weigh 1 ton, some weigh more and others less. Take this into account when comparing prices and look for information on our “price per kg”.

Frequently Asked Questions

How much do the pellets cost?

You can always find the current prices for pellets on our online store at

Is the pellet price inclusive of VAT?

The pellet price displayed before adding the item to the cart is excluding VAT. There are three VAT rates applicable for pellet purchases:

  • 0% – for legal entities that are VAT payers;
  • 12% – for private individuals;
  • 21% – for legal entities that are not VAT payers.

The appropriate VAT rate will be applied in the shopping cart when the customer specifies their status.

    Are the pellets available?

    If there is an option to purchase pellets on our online store and no notification indicating that the pellets are sold out, then they are available, and you can safely place your order.

    How long does pellet delivery take?

    The delivery time for pellets is variable and depends on demand and the season. In spring and summer, delivery takes 5 to 10 business days, while in autumn and winter, it may take up to 15 business days.But mostly our logistics company deliver it on those 5-10 days.

    What is the cost of delivery?

    Delivery costs will be visible in the shopping cart and are calculated automatically based on the desired quantity of pallets and inputting the precise delivery address (postal code is mandatory).

    How many pallets can be delivered with one truck?

    Within a single delivery, it's possible to transport from 1 to 10 pallets. If there are more than 10 pallets in an order, two trucks will be provided for delivery.

    What type of truck facilitates the delivery?

    The truck arriving at the delivery location is approximately 12 tons in weight, 9 meters long, 2.45 meters wide, and 4 meters high. The vehicle is equipped with a lift for unloading pallets from the truck and pallet wheels to move them from the lift. Please note that the driver will only move the pallet within a 5-meter radius of the truck's location.

    What must be ensured at the delivery address for successful delivery?

    If it is not possible to deliver the cargo due to the recipient's fault, costs for returning the goods to the nearest Schenker terminal will be incurred.
    There should be no weight-restrictive signs on the road. Standard delivery is carried out with vehicles whose gross weight exceeds 10 tons.
    If the customer has restrictions on the width or height of the access road, there is an option for:

    • Delivery to be split and carried out with a vehicle with a gross weight of 5 tons, which can provide a 2-ton delivery at a time. The customer will incur additional delivery costs (50% of the total delivery costs for each additional trip).
    • Delivery by a bus that can provide a 2-ton delivery at a time with reloading at the terminal and palletizing. The customer may opt for manual loading, as the weight of a single unit must not exceed 500kg.

    It is crucial that, when making deliveries to private residential areas, the driver has the option to exit from the delivery site. This means either executing a safe turning maneuver or exiting on the opposite side (without using reverse gear).
    The cargo recipient must respond to the driver's calls.
    Deliveries are not provided with a manipulator.
    The access road and gate width should be at least 4 meters wide. The road surface must be stable and firm to safely accommodate the cargo vehicle, which has a gross weight exceeding 10 tons.
    Please verify that low-hanging branches do not obstruct the truck's access. In winter, the access road should be cleared.
    When making deliveries to private residential areas, make sure there is a sufficiently large, open area for the cargo vehicle to maneuver.
    For unloading pallets from the truck, a solid ground surface is necessary for using pallet wheels to lower the pallet. If the unloading area has grass, gravel, or sand, please prepare a sturdy material (boards, metal/wooden sheets, etc.) on which the pallets can be placed.

    Will the driver bring the pellets indoors?

    The delivery service does not include bringing the pellets indoors, and this service cannot be arranged.

    How will I be notified of the expected delivery of my order?

    On the day your order is handed over to the courier, you will receive an SMS from DB Schenker to the phone number provided in the order. By opening the web link sent in the message, you can confirm the offered delivery date or choose a more convenient one. On the day of delivery, the driver will call 1 hour prior to arrival. And in that day you need to wait the courrier.
