Softwood vs Hardwood Pellets: Why Softwood Is Best for Your Boiler
When people first research wood pellets, they often ask: are softwood or hardwood pellets better for stoves and boilers?
It’s a fair question. Many assume hardwood must always be superior because it is denser as firewood. However, with wood pellets the story is very different.
In this guide, we’ll explain the key differences between softwood pellets and hardwood pellets, show why softwood offers more efficiency for boilers and stoves, and highlight why SDL Pellets only produces ENplus A1 softwood pellets.
What Are Softwood Pellets?
Softwood pellets are made from coniferous species such as pine, spruce, or fir.
Key features of softwood pellets include:
- Lower density, but packed with energy per kilogram.
- Higher resin content, which helps them ignite quickly.
- Superior calorific value, often higher than hardwood equivalents.
- Low ash output, which means less cleaning and maintenance.
These qualities make softwood pellets an excellent choice for domestic boilers and pellet stoves.
Takeaway: Softwood pellets burn hotter, cleaner, and are highly efficient for heating systems.
What About Hardwood Pellets?
Hardwood pellets are made from deciduous species such as oak, beech, or ash.
While they are denser, that does not necessarily make them better. In fact:
- Hardwood pellets ignite more slowly due to lower resin levels.
- Their calorific value per kilogram is often slightly lower than softwood.
- Ash content can vary and may require more frequent cleaning.
Many people assume hardwood must be “premium” because of the name. But in pellet form, that traditional firewood advantage does not carry over.
Takeaway: Hardwood pellets are not inherently better; in many cases, softwood outperforms them.
Which Pellets Are Better for Boilers and Stoves?
When tested in modern biomass boilers and pellet stoves, softwood pellets consistently deliver stronger results.
Why softwood pellets excel:
- Faster ignition due to higher resin levels.
- Higher energy efficiency, giving more heat per kilogram.
- Lower ash content, keeping boilers running cleanly.
The crucial factor, however, is ENplus A1 certification. This standard ensures pellets meet strict requirements for ash, durability, and moisture. Both hardwood and softwood can meet this mark, but high-quality softwood pellets deliver exceptional performance every time.
Takeaway: For reliable heat and boiler efficiency, ENplus A1 softwood pellets are the superior choice.
Why SDL Pellets Only Produces Softwood
At SDL Pellets, we’ve specialised in ENplus A1 and BSL-accredited softwood pellets since 2018. We focus on softwood because:
- Our testing shows it provides the best heat output for domestic boilers.
- Customers benefit from cleaner burning and reduced maintenance.
- UK softwood resources are sustainable, traceable, and reliable.
By choosing SDL Pellets, you know you’re getting premium UK-made softwood pellets with zero compromise.
Takeaway: We only sell softwood because it gives our customers the best results.

Another key factor is where your pellets come from. Imported pellets often travel thousands of miles, increasing their carbon footprint and risking inconsistent quality.
SDL Pellets are:
- Produced in Gloucestershire, using sustainable UK forestry byproducts.
- Certified under ENplus A1 and BSL for quality and sustainability.
- Delivered directly to households and businesses across the UK through our own fleet of pellet lorries.
This closed-loop approach ensures nothing goes to waste. Every part of the tree is used across our forestry, sawmilling, biomass, and pellet operations.
Takeaway: Locally made pellets reduce carbon impact and guarantee a reliable supply chain.
Delivery Options to Suit Your Home
Whether you heat a rural cottage, a modern home, or a commercial site, we make sure pellets arrive in the way that suits you best:
- Bagged softwood pellets: perfect for stoves and smaller boilers, easy to store and handle.
