It is a combination of two chimney systems thanks to a common outer wall of PK (chimney hollow block), PKW (chimney and ventilation hollow block) which meets the highest requirements of the applicable European standards. The system includes:

  • SKC-CM UNIWERSAL ceramic chimney system is designed for open combustion chamber boilers fired with solid, liquid and gaseous fuels where the temperature of flue gas does not exceed 600°C (T600). It is a three-layer system, which is a combination of a ceramic pipe, mineral wool insulation and outer wall (PK, PKW), operating under negative pressure. Operation is carried out both in dry mode (no condensation) and in wet mode (with condensation).  
  • SKC-T KONDENSAT ceramic chimney system is intended for closed combustion chamber boilers fired with liquid and gaseous fuels. It is a concentric system in which the inside of the chimney outer wall is used to supply air for combustion, and the ceramic pipe located in it is used to remove flue gas from the heating device. The combustion air flows in the opposite direction to the flue gas and thereby is heated, which increases the efficiency of the boiler.


SKC-CM chimney system meets the requirements of PN-EN 13063-1 T600 N1 D 3 G20 and PN-EN 13063-2 T400 N1 W 3 O20, respectively confirmed by Factory Production Control Certificates No. 1020-CPR-030040624 and No. 1020-CPR-030040625. We offer it in sections: Ø140, Ø160, Ø180, Ø200, Ø250.

SKC-T KONDENSAT chimney system meets the requirements of EN 13063-3 T200 P1 W 3 O20 confirmed by the Factory Production Control Certificate No. 1020-CPD-030040777 and we offer it in six sections: Ø100, Ø140, Ø160, Ø180, Ø200, Ø250.



Advantages of the DUO - SKC-CM + SKC-T:

  • It is possible to connect the chimney to any type of solid fuel boiler (coal, wood, eco peas, briquette, peat), liquid fuels (fuel oil, kerosene) and gas fuels (natural gas, propane butane),
  • It is possible to connect several boilers to a common system,
  • Changing the type of energy source, no additional chimney modifications are required,
  • Soot fire resistant G (20),
  • High acid resistance,
  • Fire safety, thanks to the excellent fire resistance class (external to external) EI-90; LA90,
  • Used for all types of open combustion furnaces, including low-temperature boilers with flue gas outlet temperatures from 40ºC,
  • Safe removal of liquefied aggressive combustion residues,
  • The highest class of WA vapor permeability,
  • Smooth walls of ceramic liners minimize friction during movement and ensure better draught,
  • Simple and quick installation thanks to the use of modern, lightweight LECA hollow blocks and thin-layer adhesive mortar,
  • High thermal resistance,
  • Very good ventilation of the insulation,
  • Low weight, high strength, high thermal resistance and versatile use of the outer wall of the chimney (Mn),
  • Excellent thermal and insulation properties λ = 0.055-0.08 W/(m·K).
