A Glow-worm boiler can last for approximately 10-15 years with proper maintenance and regular servicing.

It is recommended to have an annual service by a qualified professional to ensure its longevity and proper functioning.

There could be several reasons why your Glow-worm Ultracom-18hxi boiler is not igniting. Some possible causes include:
1. Gas supply issues: Ensure that the gas supply to the boiler is turned on and that the gas valve is open.
2. Pilot light or ignition electrode: Check if the pilot light is lit or if the ignition electrode is functioning properly. If not, it may need cleaning or replacing.
3. Ignition leads: Examine the ignition leads for any signs of damage or corrosion. Faulty leads can prevent the ignition sequence from occurring.
4. Blocked burner or flue: A blocked burner or flue can prevent the boiler from igniting. Check for any blockages and clean them if needed.
5. Low gas pressure: If the gas pressure is too low, the boiler may fail to ignite. Consult with a qualified heating engineer to check and adjust the gas pressure if necessary.
6. Faulty components: There may be an issue with other components such as the ignition PCB, gas valve, or flame sensor. These components may need to be inspected by a professional and replaced if faulty.
It is recommended to consult with a qualified heating engineer or Glow-worm customer support to diagnose and resolve the specific issue with your boiler. They will have the knowledge and expertise to troubleshoot effectively and ensure safe operation.
