What Our Engineer Found
While carrying out routine checks, our engineer noticed visible corrosion and moisture around the flue system. On closer inspection, the problem became clear:
- A flue seal had perished, allowing condensation vapour to escape into the space between the inner and outer flue.
- Over time, this vapour caused severe rusting to the outer flue section.
- The corrosion had advanced to the point where the flue had split, allowing carbon monoxide fumes to spill into the room.
To the customer, the boiler appeared to be working perfectly well. However, this hidden fault was creating a very real risk of carbon monoxide exposure.
Why This Fault Was So Dangerous
A damaged or split flue is one of the most serious faults that can occur on a gas boiler system.
Here’s why this situation was so concerning:
- Carbon monoxide is odourless and invisible, meaning it can build up unnoticed.
- Condensing boilers naturally produce more moisture, making seals and joints even more critical.
- Once a flue seal fails, acidic condensate vapour accelerates corrosion, weakening the pipework.
- When the flue rusts and splits, combustion gases leak into the property rather than safely venting outside.
In this case, the issue had developed slowly, but by the time it was found, the flue was completely compromised.
How Afterglow Made the Boiler Safe
Our Gas Safe engineer immediately made the appliance unsafe to use and carried out a full system assessment.
The steps taken included:
- Removal of the damaged flue sections
- Installation of new flue pipework and seals to manufacturer standards
- Full flue gas analysis to verify safe combustion and emissions
- Comprehensive boiler service and safety certification
After the repair and safety checks, the boiler was restored to full, safe operation.
The Importance of Regular Boiler Servicing
