How are wood briquettes different from ordinary firewood?
If you have a fireplace, wood stove or all-burner have, sooner or later you are faced with the choice: do you use wood briquettes or ordinary firewood? Both fuels are widely used for heating, but there are significant differences in composition, performance, durability and cost. In this article, you will discover the main differences between these two forms of wood fuel so that you can make an informed choice.
What are wood briquettes?
Wood briquettes, also known as compressed wood waste named, are cylindrical or block-shaped pieces of compressed sawdust and wood chips. They are produced without chemical additives, making them an eco-friendly alternative to traditional firewood.
Characteristics of wood briquettes:
- High efficiency: Due to their low moisture content (less than 10%), they burn more efficiently than ordinary wood.
- Long burn time: Some types of briquettes can glow for up to 4 hours.
- Sustainably produced: Often made from leftover material from the wood industry.
- Less storage space needed: Compact shape ensures efficient storage.
What is just firewood?
Firewood, also known as firewood or open firewood, consists of split logs or branches of deciduous or coniferous trees. It is the traditional fuel for fireplaces and stoves and is often produced locally.
Characteristics of ordinary firewood:
- Natural look: Gives an authentic atmosphere with crackling fire.
- Different types available: Oak, beech, ash and birch are popular choices.
- Less processed than briquettes: Is usually only cleaved and dried.
- Lower efficiency with wet wood: Freshly cut wood contains a lot of moisture (up to 50%) and needs to dry first.
The main differences between wood briquettes and ordinary firewood
| Feature | Wood briquettes | Ordinary Firewood |
|---|---|---|
| Energy content per kg | 4.5 - 5.0 kWh/kg | 3.0 - 4.0 kWh/kg (depending on humidity) |
| Moisture | <10% | Between 15% (dried) and 50% (fresh) |
| Sustainability | Highly durable (residual product) | Sustainable if derived from responsible forest management |
| Space-saving storage | Very compact; little space required | Less compact; more storage space required |
| Beauty of the fire view | Less flame, more glow | Beautiful flames and crackling fire |
| Creation rate | Slightly slower to light without firelighters | Quick to light with dry wood and kindling |
| Cost per unit of consumption* | Lower due to higher yield per kg | Slightly higher due to lower yield per kg (especially with wet wood) |
| *Depending on local prices and availability. | ||
Sustainability: which type is more environmentally friendly?
Both briquettes and firewood can be sustainable, but there are nuances:
- Wood briquettes: Often made from sawdust that would otherwise be thrown away. No trees have to be cut down for production.
- Sustainable firewood : If it comes from FSC- or PEFC-certified forests, this too is a responsible choice. Pay attention to provenance!
- Milieu Centraal : advises to always burn dry wood and limit smoke production for less particulate emissions.
- *Please note*: Wet or untreated wood can emit harmful substances during combustion.
Cost comparison: which is more advantageous?
Looking at the price per kilo, ordinary firewood often seems cheaper. But when you include the yield in the calculation, it turns out buy wood briquettes often more advantageous in the long run.
Cost factors to consider:
- Purchase price per kg or cubic metre;
- Energy yield per kg;
- Storage costs and space (especially with wet wood);
- Time required for wet wood to dry (minimum 1 year);
- Cleaning costs due to soot formation when wet wood is used.
Cleaning & Maintenance of your stove or fireplace
Chimney maintenance is essential with both briquettes and firewood. However, briquettes cause less soot formation thanks to their low moisture content. This means less risk of chimney fire as well as lower maintenance costs over time.
When do you choose which fuel?
Opt for wood briquettes if you...
- Have less storage space;
- Want to generate heat quickly with little smoke;
- Want to fire sustainably with high efficiency;
- Want less cleaning work on your stove or chimney;
- Precise control over combustion time desired (e.g. overnight annealing briquettes).
Opt for just firewood if you...
- Really enjoy an atmospheric fire with flames;
- Locally harvested dry firewood you can obtain;
- Self enjoys chopping, cleaving and drying;
- Have time to stock up;
- Natural materials preferred without processing.
Frequently asked questions on the difference between briquettes and firewood (FAQ)
Which is better: briquettes or regular firewood?
It depends on your situation. Briquettes provide more heat per kilo and are more sustainable if they are made from residual materials. Firewood, on the other hand, offers an authentic fire with crackling flames. The choice depends on preferences such as ambience, storage space and durability.
Are briquettes more expensive than regular wood?
No, despite the fact that the price per kilo may sometimes seem higher, briquettes yield more energy per kilo, making them often more economical to use than ordinary firewood.
Do briquettes make more mess than regular wood?
Definitely not! Briquettes actually produce less ash and soot than wet or untreated firewood. This will keep your stove cleaner and you will have to clean it less often.
Are all types of briquettes the same?
No. There are different types such as RUF briquettes, Pini Kay briquettes and night briquettes. Each type has unique characteristics in terms of shape, burning time and heat output.
