A flexible tube (80 mm) introduced through the chimney of the building. Depending on the configuration of your home, if the suction cup is not suitable, the combustion gases will be evacuated via a flexible tube 80 mm in diameter introduced into the chimney of the building (diagram attached). Price of the tubing: 10 meters of PP tubing, including accessories, an additional €800 including 6% VAT. Important to know: If you replace an old atmospheric boiler connected to a chimney, with a condensing boiler, you must surely pipe the chimney. In this case, the supplement of 800 € is required.
