It is a combination of two chimney systems thanks to a common, modern outer wall from the ENERGO group meeting the highest requirements of the applicable European standards. The system includes:

ENERGO KERAMIC 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 two-layer system, which is a combination of a ceramic pipe and an outer wall - the ENERGO chimney hollow block, operating under negative pressure. The operation takes place both in dry mode (no condensation) and in wet mode (with condensation).

PLAST KONDENSAT chimney system is an air/combustion system (SPS) designed for closed combustion chamber boilers. It consists of an acid-resistant pipe made of plastic, which removes flue gas from the boiler and an air duct (inside the outer wall of the chimney) which removes air for combustion.


ENERGO KERAMIC chimney system meets the requirements of EN 13063-1 T 600 N1 D 3 G20 and EN 13063-2 T400 N1 W 2 O20 respectively confirmed by Factory Production Control Certificates No. 1020-CPR-030040624 and No. 1020-CPR-030040625 and we offer it in sections: Ø140, Ø160, Ø180, Ø200.

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 ENERGO DUO system:

  • 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 flue gases temperatures from 40°C,
  • 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,
  • 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).
