Sunflower husk pellet is a biomass fuel made from 100% sunflower seed husks. No added binders or additives are used during production; the pellets are produced solely by high-pressure compression.

Sunflower husk pellets have a calorific value of 18–20 MJ/kg (approx. 5 kWh/kg). This means that the energy content of approximately 2 kg of pellets is equivalent to that of 1 m³ of natural gas.

The main differences are ash content and price. Wood pellets typically have an ash content below 1.5%, while sunflower husk pellets contain around 2–3%. However, sunflower husk pellets are generally more affordable, making them a more economical heating solution in many cases.

Sunflower husks naturally contain more minerals than wood, which results in more ash remaining after combustion. This is not a defect but a natural characteristic of the raw material.

Pellets provide more even and controlled combustion, resulting in a steadier flame. Firewood produces a more natural-looking flame, but its intensity can fluctuate more depending on the wood’s moisture content and size.

Yes. Most pellet boilers require different combustion settings for different types of pellets. When switching from wood pellets to sunflower husk pellets, recalibrating or properly adjusting the boiler is recommended.

Pellets should always be stored in a dry, covered place protected from moisture. Once opened, the packaging should also be kept in a dry environment, as pellets readily absorb moisture, which can reduce their quality and heating performance.

A pellet boiler can supply an entire central heating system and is therefore suitable for heating a whole house. A pellet stove is primarily designed to heat one or several rooms, while also providing the visual comfort of a visible flame.

Poor-quality pellets may produce more ash, cause more frequent blockages in the heating system, reduce heating efficiency and result in uneven combustion. Using pellets of consistent quality from a reliable source helps prevent these problems.

Sunflower husk pellets generally have a higher ash content than premium wood pellets, so the boiler may require slightly more frequent cleaning. However, the actual cleaning frequency depends largely on the type of boiler and how intensively it is used.

Like pellets, briquettes are a natural fuel made from renewable raw materials compressed under high pressure. The pressing process creates a dense structure, allowing the briquettes to burn more slowly, provide heat for longer and offer an economical heating solution.

Briquettes are larger and designed for manual feeding, while pellets are suitable for automatic feeding systems.

They can be used in fireplaces, tiled stoves, solid-fuel boilers and stoves.

Sunflower husk briquettes burn evenly, provide high heat output and, thanks to their dense structure, remain glowing for longer than conventional firewood. With sufficient air supply, they provide clean combustion, although they may produce slightly more ash than wood briquettes.

The calorific values of the two products are very similar, as they are made from the same raw material. The main difference lies not in their energy content but in how they are used: pellets are designed for automatic pellet boilers, while briquettes are primarily used in traditional fireplaces, tiled stoves and solid-fuel boilers.

No. Due to their size and shape, sunflower husk briquettes are not suitable for use in automatic pellet boilers or pellet stoves. These appliances are designed specifically for pellet fuel.

For best results, start the fire with dry kindling, then place the briquettes onto the glowing embers.

The amount required depends on the size and insulation of the building, weather conditions and the type of heating appliance used. There is no universal daily amount, but thanks to their high energy content and long burn time, briquettes generally require less frequent refuelling than many conventional fuels.

Thanks to their low moisture content and dense structure, sunflower husk briquettes burn more evenly, have a higher energy density and require less storage space than conventional firewood. They are also cleaner to handle and, when stored properly, retain their quality for longer.

Sunflower husk briquettes typically have an ash content of around 3%. This means that relatively little ash remains after combustion and, with proper maintenance, it does not interfere with the efficient operation of the heating appliance.
