Chimney & Flues | Commercial Gas and Boiler Services

The new condensing gas boilers work on a different principle as the flue gas temperature is very low it has little lift and relies on a positive pressure supplied by the boiler fan to remove the flue gasses. This means that the flue must be sealed and to ensure the flue can deal with the acidic condensate made of 316-grade stainless steel.
