Wood Pellet Quality: Why it Matters

3 minute read

When it comes to heating your home with biomass fuel, wood pellets have emerged as a popular and eco-friendly choice. Made from compressed sawdust, typically a by-product of sawmills, wood pellets offer a sustainable alternative to traditional fossil fuels.

However, not all wood pellets are created equal, and their quality can significantly impact your heating experience. In this blog, we'll explore why wood pellet quality matters and what standards you should look for when purchasing them.

Along with having installed wood pellet boilers for almost 20 years, we also sell wood pellet fuel to our customers, so we are well positioned to give some advice on this subject.


The Anatomy of Wood Pellets

Wood pellets are the result of a meticulous process that involves compressing sawdust into small, cylindrical shapes.

This compression takes place at specialised pellet processing plants, where the innate binding agents within sawdust are skilfully harnessed to craft the desired shape and structural integrity.

The outcome is the creation of compact, highly efficient biomass fuel pellets, which can be employed in an extensive array of heating systems.

This versatility makes wood pellets a sustainable choice, appealing to environmentally conscious homeowners and businesses seeking efficient and eco-friendly heating solutions.


Quality Standards Matter

To ensure that you're getting the most out of your wood pellets, it's crucial to be aware of the quality standards they should meet. In the UK, wood pellets should be accredited to either the ENPlus A1 or A2 Standard.

These standards specify the following criteria:

  • Length - 5-30mm
  • Diameter - 5-6mm
  • Moisture Content - 8-10%
  • Ash Content - ≤ 0.5%

Meeting these standards results in wood pellets with a bulk weight of approximately 650kg/m³, which is an important factor in storage and transportation efficiency.

Wood pellets that meet these stringent standards not only adhere to quality, but also deliver remarkable efficiency, generating an impressive 4.9 kilowatt-hours (kWh) of heat per kilogram, making them a top choice for heating solutions.


Proper Storage and Delivery

To safeguard wood pellet quality, attention to storage and delivery is crucial. High quality wood pellets can lose their edge if not handled correctly.

Store them in dedicated, enclosed units equipped with an inspection hatch to shield against moisture and contaminants.

During delivery, opt for external filler tubes for a smooth and clean transfer, much like oil delivery. This diligent approach ensures consistent pellet quality, reduces combustion issues, and minimizes maintenance costs.


Wood Pellet Quality: The Benefits

Choosing high quality wood pellets for your heating needs is not just a matter of preference; it can significantly impact your overall heating experience and the environment.

Let's delve deeper into the advantages of investing in top-tier wood pellets.



High-quality wood pellets are designed to burn cleanly and efficiently. Their consistent size and low moisture content allow for a controlled and even combustion process.

This means that more of the energy stored in the pellets is converted into heat, maximising the heat output of your heating system. In practical terms, it translates to a warmer and more comfortable environment for you and your family.


Reduced Maintenance Costs

When you opt for high quality wood pellets, you're also investing in the longevity of your heating equipment. Inferior pellets with higher moisture content or impurities can lead to excessive soot and ash build-up in your heating system.

This build-up can reduce the efficiency of your equipment, resulting in higher servicing and maintenance costs over time. By choosing high quality wood pellets, you not only enjoy a more efficient system, but also save on long-term maintenance expenses.


Environmental Impact

Beyond the immediate benefits to your heating system, high quality wood pellets contribute to a cleaner and more sustainable environment.

These pellets burn with lower emissions, releasing fewer harmful pollutants into the atmosphere. The reduction in emissions, such as particulate matter and greenhouse gases, not only ensures better air quality but also contributes to a smaller carbon footprint.

By using cleaner-burning pellets, you actively participate in mitigating climate change and fostering a healthier environment for current and future generations.
