We are proud that Wood-Břežany s.r.o. offers the strictest certified wood pellets on the market. Our products undergo rigorous testing by independent bodies that guarantee quality and performance in every bag.

What is ENplus Certification? Definition and Origin

ENplus certification is a globally recognised certification system initiated in 2010 by the European Pellet Council (EPC). It is a third-party certification scheme, meaning that independent and impartial auditing bodies verify compliance with the standards.

The ENplus system is based on the ISO 17225-2 and ISO 9001 standards and focuses on ensuring exceptionally high quality of wood pellets and the implementation of good practices across a range of activities, including pelletisation, storage, bagging, trade, and transportation of wood pellets.

Unlike the industrial sector, where producers and sellers conduct their own laboratory tests, ENplus certification was specifically developed for the household heating sector. It provides consumers with the assurance that their pellets will function optimally in stoves and boilers.

The ENplus scheme was initiated in 2010 and was developed to ensure the quality of wood pellets intended for small-scale use. Today, over 1,100 certified companies worldwide participate in the scheme.

How the ENplus Certification Chain Works

One of the key aspects of ENplus is that it covers the entire supply chain of wood pellets. From production to delivery to your home, the system monitors and verifies quality at every step.

Certification bodies are independent organisations recognised to carry out certification within the ENplus scheme. They are responsible for the entire certification process and for verifying compliance with ENplus requirements. Inspection bodies conduct inspections of facilities, equipment, processes, and the client’s management system, including collecting samples for testing.

The ENplus scheme includes three main modules:

Production – Control of raw materials, production, and storage
Trade – Monitoring of qualitative status during distribution
Service Provision – Bagging, storage, and transportation of the final product

Here at Wood-Břežany, we adhere to these standards at every step of our production and sales process for wood pellets.

Quality Classes: ENplus A1 vs. A2

There is not just one level of ENplus certification. The system has three quality classes, with A1 and A2 intended for domestic heating, while B is intended for industrial applications.

ENplus A1: Premium Quality for Domestic Heating

ENplus-A1 certifies the highest quality grade. Our A1 category wood pellets are made exclusively from hardwood or softwood without chemical treatment.

Here are the key parameters:

Characteristic	ENplus A1	ENplus A2	ENplus B
Ash Content (%)	≤ 0.7 %	≤ 1.5 %	≤ 2.0 %
Moisture Content (%)	≤ 10 %	≤ 10 %	≤ 10 %
Energy Value (kWh/t)	≥ 4,600	≥ 4,600	≥ 4,600
Density (kg/m³)	600-750	600-750	600-750
Mechanical Durability (%)	≥ 97.5 %	≥ 97.5 %	≥ 95 %
Recommended Use	Domestic stoves and boilers	Larger installations	Industrial applications

The ash content for ENplus, a key metric for wood pellets, is ≤0.7% by weight for ENplus-A1 (premium quality used in domestic boilers and stoves) and ≤1.5% by weight for ENplus-A2 (used in larger installations).

Why is lower ash content important? It means that more energy from the pellets is actually used to heat your home, while less energy is lost to cleaning solid waste from your stove.

ENplus A2: Standard Quality for Larger Installations

ENplus-A2 allows for a wider range of raw materials, for example, with an ash content of up to 1.5%. These pellets are ideal for larger installations that can better tolerate more ash.

The ENplus A2 class includes combined raw materials, such as whole trees without roots, by-products, and residues from wood processing without chemical treatment, forest residues, and tree trunks.

Technical Specifications and Standards

For those who want to better understand the technical side of ENplus:

Moisture Content

Moisture content is one of the key quality indicators for wood pellets. In accordance with the European certification for wood pellet quality (DIN51731), the requirement for moisture content for both domestic and industrial use is less than or equal to 10% by weight.

Density and Bulk Density

The bulk density of wood pellets is significantly higher than that of wood chips, which can improve combustion speed. According to the ENplus standard, the result should be between 600-750 kg/m³.

Mechanical Durability of Pellets

Mechanical durability is also a good representative parameter of wood pellet quality. In accordance with the ENplus specification, the quality standard for wood pellets is greater than 97.5%.

Benefits of ENplus Certified Pellets

Why should you choose wood pellets from Wood-Břežany with ENplus certification? The answer is simple: quality, trust, and long-term savings.

1. Guaranteed Quality and Performance

ENplus certification guarantees that your wood pellets meet strict quality standards, ensuring consistent performance. When you buy certified pellets, you have the assurance that they will behave predictably and efficiently.

2. Lower Emissions and Cleaner Heating

Environmentally conscious customers have long known that good pellet quality is convincing not only in terms of calorific value but also emits fewer emissions, which is why they trust well-known certifications to find high-quality products.

3. Less Maintenance and Lower Costs

This is especially important for smaller boilers and stoves used in households, as they have lower tolerances. Quality pellets with lower ash content mean you don’t have to clean and service your stove as often.

4. Market Access and Safety

ENplus certification enhances market access by providing trustworthiness and recognition in domestic and international markets. ENplus certified pellets make up 80% of pellets sold in the European heating sector.

How to Identify Authentic ENplus Certification

One of the most common problems is the purchase of fake or low-quality pellets that incorrectly claim certification. How to protect yourself?

Check the Logo and ID Number

Every certified bag of pellets should have the official ENplus logo with a unique number. This allows you to verify its authenticity in the official ENplus database.

Certification bodies, which are independent organisations recognised to carry out certification within the ENplus scheme, are responsible for the entire certification process and for verifying compliance with ENplus requirements.

Inspect the Packaging Contents

Genuine ENplus pellets should have:

Clear printing of the grade (A1, A2, or B)
Information about the producer and distributor
Initial weight and date of packaging
Data on energy value

At Wood-Břežany, we offer only fully certified products with complete documentation and transparency.

Practical Tips: How to Choose the Right Pellets

For Domestic Stoves and Boilers

If you have a domestic heating system, we recommend ENplus A1. Lower ash content means cleaner combustion and long-term savings on maintenance.

Where to Buy Quality Pellets?

Wood-Břežany s.r.o. offers a complete range:

Storage and Safety

Pellets should be stored in a dry place protected from moisture. If exposed to moisture, their efficiency is drastically reduced.

Frequently Asked Questions about ENplus Certification

1. What is the difference between ENplus and DINplus?

Both are recognised European standards. DINplus was developed based on the German DIN 51731 and Austrian ÖNORM M 7135. The scheme includes the implementation of internal quality management and an annual external audit without prior notification. ENplus, however, is the most widespread globally and covers the entire supply chain.

2. How many pellets do I need for one year of heating?

This depends on the size of your home, how well it is insulated, and the weather in your region. On average, 3-8 tonnes per year are calculated for a medium-sized household. We have a specific calculator in our FAQ section.

3. Are ENplus pellets safer than non-certified ones?

Absolutely. Quality certification protects producers from bad players in the market. By advocating that consumers use only certified pellets, it ensures that the pellets will behave correctly in stoves and boilers, thus protecting the reputation of wood pellets as a quality fuel.

4. What is the energy value of ENplus A1 pellets?

ENplus-certified A1 pellets guarantee that each tonne provides a minimum of 4,600 kWh of energy. In practice, they often provide more due to strict quality control.

5. How long is ENplus certification valid?

ENplus certification is valid for three years. It includes annual supervision inspections and a certification inspection every three years. This means that manufacturers are under constant supervision to maintain standards.
