We are market leader in plastic gas flue systems for condensing boiler technology. This is the result of continuous innovation and development, e.g., our new revision element reduces the flow resistance of the inspection elbow by up to 50 %, thus improving effiency while substantially simplifying the task of performing regular technical inspections.

In addition to systems, which have been specially developed for condensing boiler technology, we also offer systems for all conventional fireplaces with flue gas temperatures of up to 120 °C. For high gas flue temperatures of up to 250 °C, we also supply metallic gas flue systems made of aluminium, sheet steel or stainless steel.

In multi-occupancy houses and larger buildings there are usually several boilers operating in parallel, connected to a single gas flue shaft. For such situations, CENTROTEC supplies installation concepts for cascade and multi-boiler systems. Gas flue pipes made from polypropylene and system components make these systems easy to install.

High quality standards are required whenever chimneys are being renovated. The chimney renovation system has been developed specifically for retrofitting in chimneys; it leaves the roof and the chimney walls intact. The system is made from either aluminium or polypropylene and is available in a variety of diameters.
