Black Steel Chimneys for Stoves and Fireplaces

Thick-walled black steel flue pipes are designed to connect wood-burning stoves, sauna heaters, fireplaces, and solid fuel boilers to the main chimney. These elements are installed indoors and serve as the starting section of the smoke exhaust system. They connect directly to the outlet of the heating appliance and provide a safe connection to a brick, ceramic, or insulated steel shaft.

All products are CE certified and comply with the European standard EN 1856-2. The elements are soot fire resistant (Class G) and designed for operating temperatures up to 600°C (T600 class). Products are constantly available in stock, allowing for the rapid assembly of a system of any configuration.

Our products in this category are divided into two lines: the standard series and the Ferro-Lux interior series.

Is this system right for you?

Before ordering, make sure that black steel chimneys are exactly what you need for your project:

Yes, if you have a solid fuel appliance: You plan to connect a classic wood-burning stove, fireplace insert, sauna heater, or wood/briquette boiler.
Yes, if you need a starting section indoors: The elements will be installed inside a heated room or boiler room (from the heating appliance to the entrance of the main chimney), and you want to use the residual heat to warm the room.
No, if the chimney runs outdoors or passes through a wooden ceiling: For outdoor installation, passing through a cold attic, or combustible structures, insulated sandwich chimneys are required (e.g., our IZOKOMPAKT series). Otherwise, condensation will form, and the intense heat of the black pipe poses a fire hazard.
No, if you have a gas or pellet boiler: Low-temperature boilers with abundant condensation require acid-resistant stainless steel (AISI 316L).

Standard Series: Practical Classic

A system for installation tasks in boiler rooms and technical areas. The design of the elements allows you to assemble the starting section of the chimney for gas exhaust.

Key features:

Welding and connection: Longitudinal TIG weld. Simple "pipe-in-pipe" connection (socket expansion).
Material: Black steel, 2.0 mm wall thickness.
Coating: Heat-resistant black paint.

Ferro-Lux Series (Jeremias): Design and Aesthetics

A special series of elements for interiors where the chimney pipe remains visible and is part of the visual design of the room (e.g., when connecting fireplace inserts in living rooms).

Key features:

Seamless appearance: The use of laser welding and a hidden connection system with narrowing (Plug-and-socket) makes the joints less noticeable.
Coating: Matte black color (heat-resistant Senotherm 702.284 enamel).
Assortment: Includes smooth elbows without doors, adjustable bends, and decorative trim rings for finishing.

Technical Specifications and EN 1856-2 Classification
