Single-wall plastic chimney system

Single-wall plastic chimney system - an innovative solution for modern buildings

The single-wall plastic chimney system is a modern solution for many types of buildings.   It offers numerous advantages over traditional systems. At Onninen, we have extensive experience in this area. Our customers often ask for technical details and applications. That is why we have prepared a comprehensive overview of this technology.

The key elements of the system are chimney pipes and flexible inserts. They are complemented by elbows, supports and plumb clamps. The whole creates a coherent structure that removes exhaust gases. The materials used in production are high-quality plastics. They provide excellent corrosion resistance and low weight of the elements.

Advantages of a single-wall plastic chimney system

In everyday practice, we observe numerous benefits resulting from the use of this technology.   First of all, assembly is much simpler and faster than in the case of traditional solutions. The elements are lightweight and easy to transport. They do not require specialist tools for installation. This translates into lower labor costs.

Another advantage is the high resistance to aggressive exhaust fumes. The plastic does not corrode. Thanks to this, the system remains tight for many years of use. It also does not require frequent inspections and maintenance. This is a significant saving in the long term.

It is also worth emphasizing the excellent insulation properties. The single-wall system does not need additional thermal insulation. This prevents excessive cooling of exhaust gases. This translates into better efficiency of boilers and furnaces.

Types and applications of single-wall plastic chimney systems

Onninen offers various system variants tailored to specific needs.   The basic division includes systems for condensing and traditional boilers. The former are resistant to acidic condensate. They can operate in wet mode. Systems for traditional boilers, on the other hand, are adapted to higher exhaust gas temperatures.

Chimney kits are an important part of the offer. They contain all the necessary elements for the assembly of a complete system. This is a convenient solution for contractors. It eliminates the risk of omitting any of the components. A typical kit includes:

• Chimney pipes of different lengths
• Chimney system elbows
• Knee supports
• Plumbing clamps
• Roof plate
• System Splitter
• Seals

We also offer single elements for expanding or repairing existing systems. Flexible inserts are particularly popular. They allow for quick renovation of old brick chimneys. They do not require breaking down walls or other invasive work.

Our experience shows that the single-wall plastic chimney system works well in a variety of buildings.   It is most often used in single-family homes with gas boilers. It is also increasingly common in multi-family buildings. There, it usually serves collective boiler rooms. It is also found in industrial and service facilities.

Selection and installation of a single-wall plastic chimney system

The right choice of system is key to its efficiency and safety. At Onninen, we help our clients in this process. We take into account a number of factors, such as:

• Type of boiler or furnace
• Power of the heating device
• Flue pipe length
• Number and type of elbows
• Weather conditions at the installation site

Recently, we provided advice on system selection for a project for a large terraced house estate.   The investor initially considered traditional brick chimneys. After analyzing the costs and installation time, he decided on plastic systems. This allowed for significantly faster construction work. Additionally, space was saved inside the buildings.

The assembly of a single-wall plastic chimney system is relatively simple. However, it requires following a few rules. Maintaining the appropriate slopes is crucial. This ensures proper condensate drainage. Proper sealing of the connections between the elements is also important. Special gaskets supplied in sets are used for this purpose.

In the case of penetrations through ceilings and roofs, dedicated rosettes and plates are used. They ensure tightness and stability of the structure. Proper chimney extension above the roof is also important. It must take into account local wind and snow conditions.

In our daily practice, we see that proper installation translates into long-term, failure-free operation of the system.   That is why we always recommend using the services of qualified installers. Many of them have undergone training in our company. They know the specifics of the products we offer.

It is worth mentioning the issue of maintenance of the single-wall plastic chimney system. It is much simpler than in the case of traditional chimneys. The smooth internal surface limits the accumulation of soot. This makes cleaning easier and less necessary. Nevertheless, we recommend regular inspections, at least once a year.

In the Onninen offer you will find single-wall plastic chimney systems from renowned manufacturers. We especially recommend our own brand products: Onnline and Ricom. They are characterized by an excellent quality to price ratio. They were developed with the specific needs of the Polish market in mind.

We encourage you to contact our technical advisors.   They will help you choose the best solution for your specific project. They will also advise you on assembly and operating issues. This will give you the certainty that the system will operate effectively and safely for many years.
