The job
A cascade flue for three school boilers.
A replacement boiler flue at Harefield Infant School in Uxbridge, west London.
Three condensing gas boilers each connect through a drain length and an adaptor into their own Ø130 primary flue. The primaries join a common Ø200 header that falls at 3 degrees to a drain.
The Ø200 riser goes up through the existing roof opening to an open terminal with mesh, 1m above the roof. We finished and smoke tested the system on 8 October 2026 and handed over an O&M pack.
