3-Wall Solid Chimney Kit

NIKO Uni Ceramic Chimney: a chimney for solid fuels, gas, and oil

The solid ceramic chimney, developed by NIKO, a renowned manufacturer in chimney construction, represents state-of-the-art technology and the highest quality standards. The NIKO UNI ceramic chimney is universally applicable and suitable for all common fuels, including wood, coal, gas, and oil. Thus, it offers the necessary flexibility for a wide variety of heating systems in both private and commercial applications.

Thanks to first-class workmanship and the use of high-quality materials, the NIKO UNI is extremely resistant to temperature and corrosion. Even acidic condensate from the flue gas does not impair its functionality. The system's high safety factor is underscored by its soot fire resistance and the maintenance of fire resistance class F90 (90 minutes), ensuring maximum safety even in the event of a fire.

Special design elements ensure that simple installation is possible both indoors and outdoors without any problems. The comparatively low weight of the precision elements allows for easy handling as well as quick and efficient assembly. The system includes robust cladding blocks, durable ceramic pipes, and high-quality thermal insulation panels. These components ensure optimal operation of modern fireplaces with low flue gas temperatures and high efficiency.

The factory-prefabricated components make the chimney kit particularly user-friendly. This allows the chimney to be erected independently in just a few steps. The tested and certified components ensure the highest construction stability and functionality with maximum flexibility, for example through various assembly and connection options.

The NIKO UNI chimney is available as a single, double, or triple-flue version with an integrated ventilation shaft, thus adapting to the requirements of a wide variety of buildings.

Multi-flue versions as well as additional connections and inspection openings are available upon request.
