Centrotherm Collective Chimney Flue Gas Systems

When renovating high rise buildings many principles choose for individual condensing (combi) boilers. One of the main issues is to solve the problem that existing chimneys don't withstand the relative cold and wet flue gases from the condensing boiler. In many cases the installer chooses for an individual flue gas system for appartment, e.g. the Centrotherm flexible pipe with diameter DN50/58. Also another option is to install a collective flue gas system, with connections to the boilers on every floor, the so called CLV or 1/2-CLV systems.

Centrotherm has an easy to install product with excellent performance, a modular PP-based system in diameter DN110. This product is sold in many European countries during the last years. Many installers, principles and advisers gave very positive feedback.
