hopper needs loading only once a week
– this depends on the hopper capacity.
•
Better control of fuel quantity.
The small
size of the pellets allows for precise fuel
feeding. On the other hand, the supply
of air for reaching optimal combustion
efficiency is easier to adjust since the
fuel quantity in the combustion chamber
remains constant and predictable.
•
Fuel efficiency.
High combustion
efficiency is also determined by
consistently low moister content of
pellets (consistently under 10% as
opposed to 20% to 60% moisture content
of the logs). Low moisture content,
controlled fuel portions and precise
air setting means high combustion
efficiency and very low carbon oxides in
the flue gases.

When purchasing pellets, ask
for conformity declaration and
certificate issued by an accredited
laboratory and make sure the
fuel meets the requirements
indicated in the manual. If
you purchase large amount of
pellets (bulk supply for the entire
heating season for example), ask
your supplier to provde accurate
and true information about the
storage conditions.
We recommend to use pellet with size of
6 - 8 mm. Density 600 - 750 kg/m

value 4.7 -5.5 kWh/kg. Ash content – less
than 1% and moisture content up to 8%.,
EN 14961-2:2011.
The optimal density of the pellets which
guarantees their quality is 605 - 700 kg
per cubic meter.
Pellet moisture content must not exceed
10%. Make sure you store your fuel in a
dry and well-ventilated place.
The optimal pellet ash content is ≤ 1%.
This also provides for less frequent
cleaning intervals for the burner.
The table below contains the parameters
which we recommend that you take into
consideration when choosing fuel for your
burner.
