The replacement of old boilers and the replacement of collective chimneys: sooner or later, each owners association will have to take care of this. Many homeowners associations fear high costs and major nuisances for affected residents. In addition to the inconvenience and congestion of demolition work, residents sometimes suffer days without hot water or heating.
There must be a better way! We install a flue gas evacuation system which can be introduced from the roof by lowering sections of pipe through the existing chimney, gas flue or ventilation duct.
A multi-story apartment building typically has several shared flues or chimneys. The renovation is carried out one duct at a time.
In general, all municipal chimney systems (cCs) from before 2005 need to be replaced.There are 2 reasons for this. A first and very important reason is that systems prior to 2005 do not have the sealing technology (silicone gasket) in the flue gas vent pipe necessary to convert anunderpressure system to an overpressure system CSC.The other reason is that before 1992, SCC systems, regardless of their manufacture, arenot CE certified and therefore these SCC systems also need to be replaced.
