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 boilers with open combustion chamber 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 and outer wall (PK, PKW), operating under negative pressure. Operation takes place both in dry mode (no condensation) and in wet mode (with condensation).
  • PLAST KONDENSAT chimney system is an air-flue gas system (SPS) intended for boilers with a closed combustion chamber. It is made of an acid-resistant plastic pipe that carries flue gas from the boiler and an air duct (inside the outer wall of the PK, PKW chimney) that supplies air for combustion. 


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.

PLAST KONDENSAT chimney system meets the requirements of EN 14471 T120 H1 W1 O20 LE E U0 confirmed by the Factory Production Control Certificate No. 1020-CPR-030052871. We offer this system with two pipe diameters, depending on the boiler output, Ø60 and Ø80.




Advantages of the DUO chimney system: SKC-CM + PLAST - KONDENSAT: 

  • It is possible to connect the chimney to any type of boiler for solid fuels (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 combined system,
  • Changing the type of energy source, no additional chimney modifications are required,
  • Increased efficiency of condensing boilers,
  • It is possible to connect a condensing boiler at any height,
  • Soot fire resistant G (20),
  • High acid resistance,
  • Fire safety, thanks to excellent fire resistance class (from external to external) EI-90; LA90,
  • Used for all types of open combustion furnaces, including low-temperature boilers with an outlet gas temperatures from 40ºC,
  • Safe discharge 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,
  • Easy to clean and resistant to mechanical loads,
  • Easy 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 chimney outer wall (Mn),
  • Excellent thermal and insulation properties λ = 0.055-0.08 W/(mK)
