Wood Pellet Quality: The Good, The Bad and The Ugly!

Wood Pellet Quality: The Good, The Bad and The Ugly!

19 September 2016

When it comes to heating your home with wood pellets, wood pellet quality is everything. But can you really tell the quality of wood pellets just by looking at them? The short answer is: perhaps! While appearances can give you some clues, there’s more to it than meets the eye. In this guide, we’ll explore how to identify high-quality wood pellets, what to avoid, and why Woodlets pellets stand out as a premium choice for your heating needs.

How to Identify High-Quality Wood Pellets

1. Uniform Size and Shape

One of the first things to check is whether the pellets are all the same size. High-quality wood pellets should be uniform in length and width, with minimal broken pieces. Why does this matter? Your boiler is designed to handle a consistent volume of pellets. Irregular sizes can disrupt the flow, leading to inefficient burning, fluctuating heat output, and even damage to your boiler.

When you pick up a bag of Woodlets pellets, you’ll notice they are precision-engineered to meet the ENplus A1 standard, ensuring every pellet is the perfect size for optimal performance.

2. Minimal Dust and Fines

Dust and fines (tiny broken bits of pellets) are the nemesis of wood pellet boilers. Excessive dust can clog conveyors, reduce burn efficiency, and even increase maintenance costs. When inspecting a bag of pellets, there should be virtually no dust—just clean, smooth pellets.

At Woodlets, we take pride in producing pellets with less than 30g of dust and fines in a 10kg bag. This commitment to wood pellet quality ensures a cleaner burn and a longer lifespan for your boiler.

3. No Clumps or Moisture

Moisture is the enemy of wood pellets. If you notice clumps in the bag, it’s a sign that moisture has seeped in, causing the pellets to degrade. Wet pellets can block augers, disrupt the flow to your boiler, and reduce heating efficiency.

Woodlets pellets are manufactured and stored under strict conditions to prevent moisture absorption. Our large volume pelleting process ensures that every bag is dry, clump-free, and ready to burn.

4. Consistent Colour

While variations in colour can occur due to differences in raw materials, consistent colouration is a good indicator of a uniform manufacturing process. Inconsistent colour might suggest changes in wood types or additives, which could affect burn quality.

Woodlets pellets are made from 100% sustainable, locally sourced timber, ensuring a consistent product every time.

What You Can’t See: Calorific Value and Ash Content

While appearance is important, some critical factors are invisible to the naked eye. These include the calorific value (CV) and ash content, both of which have a significant impact on your boiler’s efficiency and running costs.

1. Calorific Value (CV)

The CV measures how much energy a tonne of pellets contains. The higher the CV, the more heat your pellets will produce. The ENplus A1 standard requires a minimum CV of 4,600 KWh/t, but Woodlets pellets go above and beyond, guaranteeing a minimum of 4,800 KWh/t.

This higher energy output means you’ll burn fewer pellets to achieve the same level of heat, saving you money in the long run.

2. Ash Content

Ash content refers to the amount of residue left after burning. The ENplus A1 standard allows for up to 0.7% ash per kilogram of pellets burnt. However, Woodlets pellets have an average ash content of less than 0.2%, meaning less cleaning and maintenance for you.

For every 5 tonnes of Woodlets pellets burned, a typical household generates just 35kg of ash—far less than many other brands.

How to Tell If Wood Pellets Are Bad

If you’re wondering how to tell if wood pellets are bad, here are some red flags to watch out for:

  • Excessive dust and fines
  • Irregular pellet sizes
  • Clumps or signs of moisture
  • Lack of ENplus A1 certification

Always ask your supplier for test results on calorific value and ash content to ensure you’re getting the best value for your money.
