If you need to have maximum capacity of the boiler, which means maximum heat, and–most of all–you want to reduce operational costs, choose automatically fired up Pellets Fuzzy Logic 2 boilers by Kostrzewa, which set a new direction in the design of solid fuel boilers in Poland.


The Pellets Fuzzy Logic 2 boilers are a perfect choice for:

       single-family houses

       multi-family houses

       small farms

       large farms

       industrial and commercial buildings


The Pellets Fuzzy Logic 2 boilers are the best choice for a number of ADVANTAGES:

  • The very good and durable steel exchanger of the boiler designed according to the 3T definition (  (time, turbulator, temperature).
  • The burner ready for combustion of pellets, oats and pea coal (three burner nozzles in the standard equipment of the boiler)
  • Fuzzy Logic 2 used to increase comfort of operation and reduce volume of fuel used
  • The volume of air  necessary for combustion  determined with the lambda probe (automatically dosed air is optional).
  • Rich standard equipment


Fuel types

Sawdust granulate, industrial pellets, sunflower pellets, oats, fruit stones, nut shells, pea coal and even wood.


Paliwo w postaci granulatu jest zasypywane do zbiornika o bardzo dużej pojemności. Wypełnienie takiego zbiornika w zależności od zapotrzebowania na  energię budynku pozwoli  na bezobsługową pracę urządzenia od 7 do 30 dni.

Granulate fuel is charged into a very high capacity container. Filling in this container depending on demand for energy in the building will allow unattended operation of the unit for 7 to 30 days.



  • Pellets Fuzzy Logic 2 ensures gradual and smart batching of fuel and air
  • The lambda probe is used for measuring residues of oxygen in flue gases


The Fuzzy Logic retort burner ensures:

  • very smooth and accurate feeding
  • the possibility of pellets combustion with high efficiency
  • automatic firing up of pellets


The tri-duct, steel boiler exchanger made of P265GH 4-6 mm boiler steel.


Savings and ecology

It is only possible with the Pellets Fuzzy Logic 2 boilers to make up to 20% savings.

Elimination of condensation of steam in the boiler reduces emission of carbon monoxide.
