Final Report and Recommendations: After completing the checks, the engineer will provide a detailed boiler service report. This report outlines what was inspected, any issues found, and any recommended repairs or maintenance. You may also receive a boiler service certificate, confirming that your boiler has been serviced and is safe to use.
By understanding what to expect from a boiler service, you can ensure your central heating system remains in top condition, providing reliable and efficient heating for your home. Regular servicing by a Gas Safe-registered engineer not only keeps your boiler running smoothly but also helps prevent costly repairs and ensures your boiler warranty remains valid.
What Does a Boiler Service Include?
A full boiler service involves several key checks and maintenance tasks to ensure the system operates safely and efficiently. Boiler services include inspecting the heat exchanger, checking the flue and combustion, and ensuring all components are functioning correctly. Let’s break down what’s included in the service:
1. Visual Inspection
The engineer starts with a visual inspection of the boiler and central heating system, which is a crucial part of regular boiler services. This step helps detect signs of corrosion, gas leaks, or any visible issues with the boiler’s casing, pipework, or flue terminals.
- Checking the Control Panel: Ensuring the boiler functions are operating correctly.
- Inspecting the Pipework: The engineer looks for loose joints or signs of water or gas leaks in the pipe fittings.
- Verifying Gas Appliances: If there are other gas appliances connected to the heating system, these may be inspected for potential issues.
2. Boiler Casing Removal and Internal Checks
After the visual inspection, the engineer removes the boiler casing to inspect internal components.
- Heat Exchanger Inspection: The heat exchanger is checked for cracks, corrosion, and buildup of debris that could affect performance.
- Burner and Pilot Light Inspection: The engineer ensures that the pilot light is functioning correctly, with a healthy blue flame instead of a yellow flame (a sign of carbon monoxide risk).
- Safety Devices Check: The safety devices are tested to ensure they can detect malfunctions and shut down the boiler if needed.
3. Gas Pressure Check
The engineer uses a flue gas analyser to measure the gas pressure and ensure it is at the correct gas pressure for efficient operation. If the gas pressure is too high or too low, it can lead to boiler breakdowns or poor performance.
