The job

Three boilers, one old chimney.

Three new condensing boilers into one common header, out through the existing brick chimney.

The bore was too tight to work inside and the school stayed open.

We lined the chimney from a boom MEWP and laid the header to a fall back to a drain.

Smoke tested and signed off on site.
