PP concentric chimney fittings

Concentric PP chimney fittings - the key to effective exhaust systems

PP concentric chimney fittings are an essential element of modern heating systems.   They are a key component in the discharge of flue gases from condensing boilers. In our offer you will find a wide selection of these products. We supply them from renowned manufacturers, including our own brands.

We often come across questions about the specifics of PP concentric fittings. They are made of polypropylene, a corrosion-resistant material. They discharge exhaust gases through an internal duct. At the same time, they supply combustion air through an external duct. This design ensures high system efficiency.

Types of PP concentric chimney fittings in our offer

The Onninen range includes a variety of PP concentric fittings. We offer, among others:

• Concentric elbows for chimney systems PP-AL 45°
• Concentric elbows for chimney systems PP-AL 87°
• Concentric elbows for chimney systems PP-PP 87°
• PP-AL reductions
• Reduced elbows PP-AL

Each of these elements plays an important role in the exhaust system.   Elbows allow you to change the direction of the flue pipe. Reductions allow you to connect pipes of different diameters. Thanks to this, the system can be adapted to individual needs.

In everyday practice, we see how important it is to select the right fittings. Recently, in a project for a large housing estate, we used PP-AL 87° elbows. This allowed for the effective routing of chimney flues in a limited space.

Criteria for selecting PP concentric chimney fittings

Selecting the right PP concentric fittings requires taking into account several factors. These include:

• Condensing boiler type
• Power of the heating device
• Length and course of the chimney system
• Installation conditions (inside or outside the building)
• Energy efficiency requirements

Our experience shows that the correct selection of fittings is crucial.   It affects the efficiency of the entire heating system. That is why we always advise consulting our specialists before purchasing.

In the case of modernization of older heating installations, we often recommend using PP-AL reductions. They enable the connection of a new condensing boiler to the existing chimney system. This solution is economical and effective.

Brands of PP concentric chimney fittings available at Onninen

In our offer you will find PP concentric fittings from renowned manufacturers. We pay special attention to products of the Onnline and Ricom brands.   Onnline is our own brand, guaranteeing high quality at an affordable price.   The products of this brand enjoy great trust of our customers.

Many customers ask us about the differences between the brands. From our perspective, both Onnline and Ricom offer high-quality products. They differ slightly in their application profile and technical specifications. Onnline works great in standard home installations. Ricom, on the other hand, is often chosen for more demanding industrial projects.

In our daily practice, we see a growing interest in PP concentric fittings. This is due to the growing popularity of condensing boilers. They are more energy efficient than traditional boilers. However, they require a special exhaust system.

PP concentric chimney fittings are not only a technical element.   It is also a way to increase the safety of the heating system. Thanks to their design, they minimize the risk of exhaust gases entering the room. This is particularly important in the case of boilers installed inside buildings.

Onninen recommends using complete chimney systems from one manufacturer. This ensures full compatibility of the elements and optimal operation of the whole. In our offer you will find full sets of PP concentric fittings. They enable the creation of an effective exhaust system.

Our experience shows that investing in high-quality PP concentric fittings pays off. It translates into long-term and failure-free operation of the heating system. It also reduces operating costs by increasing the efficiency of the boiler.

In case of doubts regarding the selection of PP concentric fittings, we are always here to help. Our specialists will be happy to advise and help you choose the optimal solution. We invite you to contact us and take advantage of our knowledge and experience in the field of heating systems.
