Wood pellets are the primary pellet fuel used in pellet stoves and boilers. Wood pellet energy has many advantages over other forms of wood fuel, leading to its success as the fastest mounting form of biomass heating. So why is combustion biomass pellets so much more popular than simply incineration logs for instance. One of the reasons, is with pellets you can be assured that you are buying fuel as well as not water. This may seem like a strange comment to produce, yet it is true in many cases where biomass logs and wood chips are sold for fuel. To be fuel biomass logs in addition to chips are dried naturally or seasoned down to around 30% moisture. Well, this is what should happen, however some log and chip suppliers sell fuel by a much higher moisture content. Therefore the consumer is actually paying by way of weight for water plus not energy. A high moisture content in energy has many negative effectives in terms of a lower heat value, as well as more ash in addition to creosote generated during combustion. Meaning and less temperature the energy also required more maintenance to clean and maintain the stove.

Biomass pellets on the other hand have a moisture content on average around 5% up to 10%. This moisture level is much lower than even the seasoned dry biomass logs or biomass chips. Therefore pellets may always be more expensive by way of weight than logs or biomass chips, though they are also always guaranteed to have a low moisture content, as it is simply not probable to form a pellet by a high moisture percentage. The uniform shape along with size of the pellet method they are ideal for automated pellet heating.

There are a range of different grades of pellet fuels. The most costly in addition to pricey pellet fuel are premium wood pellets. Premium wood pellets are made from specially selected biomass residues, mainly pine, spruce plus oak. The residue is sourced from timber processing operations, however the biomass used must not contain bark, as this will raise the ash content generated by means of the pellets. The ash created from premium pellets is amazingly low at around 0.5%, no other biomass energy produces so little ash. Yet this ultra low maintenance fuel does come at a price. As the resources to create premium biomass pellets also relies on the waste from other industries the prices of premium biomass pellets are the most unstable of the pellet fuels. There are cheaper biomass pellets which manufacture somewhat more ash in addition to more stable prices. On the other hand it cannot be presumed that your pellet stove can burn any other standard of pellet other than premium pellet fuel. The reason for this is because most pellet stove manufactures design the stove to burn premium pellets, as well as only premium pellets as it is much cheaper to do so. This way on the other hand the owner is very limited in their choice of fuel, along with tied in the charge changes as well as high price of premium pellet fuels. It therefore makes sense to do your research along with purchase the most fuel flexible pellet stoves in addition to boilers you can afford to save on the fee of pellet energy.
