There are mainly two types of wood pellets: resinous pellets and the hardwood pellets. Softwood pellets, made from species such as spruce, pine and fir, are often preferred because of their low ash content, which reduces clinker buildup during combustion. On the other hand, hardwood pellets, from species such as oak, present a calorific value higher, but tend to produce more ash. The choice between these two types depends on the heating and maintenance needs of the device used.
The choice of wood pellets for domestic heating is a decisive step to guarantee optimal efficiency of your pellet stove. Different types of pellets exist on the market, each having their own specificities, advantages and disadvantages. This article aims to explore the different options available to you, going through the essential characteristics to consider to make an informed choice.
The different types of wood for pellets
Wood pellets are mainly produced from two main categories of species: resinous and the hardwood. Each has distinct characteristics influencing heat output and combustion.
Resinous pellets
THE resinous pellets are often made from species such as pine, THE fir tree or thespruce. These types of pellets are generally appreciated for their low ash content, which can be as low as 0.3%. This makes them particularly suitable for regular use in pellet stoves. In addition, they benefit from a good calorific value in relation to their cost, making heating economical.
Hardwood pellets
THE hardwood pellets, for their part, come from trees such as oak or the beech. They have a slower combustion and a higher calorific value, which can be advantageous during periods of extreme cold. However, they often generate more residue (ash), leading to a need for increased stove maintenance over an extended period of time.

The calorific value of pellets
THE calorific value is an essential criterion when choosing pellets. It is often measured in kilowatt hours (kWh) per kilogram. Hardwood pellets, for example, can have a calorific value of 4.8 to 5 kWh/kg, while softwood often hovers around 4.5 kWh/kg.
Comparison between the two types
Although they are more thermally efficient, hardwood pellets may have slightly higher purchasing costs. This initial investment can be offset by increased returns over the long term. On the other hand, even with a slightly lower calorific value, resinous pellets can appeal to users concerned about their budget and the maintenance of their pellet stove.
Quality criteria for wood pellets
The choice of wood pellets should not be limited to their species. Several quality criteria must be taken into account. Here are some key elements:
Humidity rate
THE humidity level pellets directly influence their combustion. An ideal rate is between 8% and 10%. Pellets that are too wet cause incomplete combustion, causing soot and poor energy performance. This explains why high quality pellets must be stored under appropriate conditions to maintain their effectiveness.
The quality standard
Wood pellets can be certified according to different standards such as ENplus A1, DIN+ And NF. Pellets that meet these certifications attest to a high level of performance and compliance with environmental standards. It is therefore wise to favor these products in order to ensure good performance and compliance with safety standards.
Impacts on stove maintenance[/h2>
Investing in high quality pellets also has a focus oninterview of your heating system. Low quality pellets lead to a faster accumulation of residue and ash which affects the performance of the stove.
Maintenance frequency
When using wood pellets, the frequency of maintenance of your appliance may vary. Softwoods will require less frequent maintenance compared to hardwoods, due to their low ash content. Generally, monthly cleaning is suggested to keep the stove in good working order.
Price and availability of pellets
The price of wood pellets fluctuates depending on several factors, including species, quality and origin. In 2024, an observed trend is a slight increase in costs, although some brands continue to offer pellets that are competitive in terms of value for money.
Buy in bulk
Purchasing pellets in large quantities can often result in significant reductions in total cost. Additionally, many online sites and physical stores offer seasonal promotions, making them an attractive option for those looking to save money while maintaining good heating quality.
Biodegradable granules
One trend that has emerged is the use of biodegradable pellets. Made from organic waste such as agricultural residues or wood waste, these pellets present an ecological alternative. Although they have good sustainability potential, their distribution remains limited compared to conventional pellets, which can lead to supply challenges.
Comparison with traditional pellets
Biodegradable pellets have a calorific value equivalent to certain types of conventional pellets, but their effectiveness can vary depending on their composition. A good analysis of the products available on the market is essential to ensure the quality of the fuel to be used.
Regulations and labels to consider
To guarantee the safe and efficient use of wood pellets, several regulations govern their production and sale. Many manufacturers comply with quality standards to ensure optimal performance while respecting the environment.
Emission regulations
Some labels place particular emphasis on particle emission rates, certify that the granules you choose meet the level standards US regarding air quality. These considerations are essential in order to reduce the environmental impact while optimizing your heating installation.
Green label and social commitments
Take into account a green label allows us to support sustainable production methods and engage in ethical practices with respect to workers involved in wood processing. This can also guarantee traceability of the raw materials used.
Conclusion on wood pellets
Everyone is free to weigh the different criteria for choosing wood pellets for their installations. Between *softwood* and *hardwood*, personal expectations regarding performance, price and maintenance must govern. The future of your heating will depend on the decisions you make today. Which granules have you chosen to optimize your thermal comfort? Let’s discuss in the comments below the experiences and choices each of us makes.
