A boiler is the heart of any home’s heating system, keeping you warm and ensuring you have hot water throughout the year. However, to keep it running efficiently and safely, regular servicing is essential. But what exactly does a boiler service involve? If you’ve ever wondered what happens during a professional inspection, this guide will walk you through the process.
Why Is a Boiler Service Important?
Regular boiler servicing helps to:
- Ensure Safety – A faulty boiler can pose serious risks, including carbon monoxide leaks. A service checks for potential hazards.
- Improve Efficiency – A well-maintained boiler runs more efficiently, reducing energy consumption and keeping your bills in check.
- Prevent Breakdowns – Routine servicing helps identify and fix minor issues before they turn into costly repairs.
- Maintain Warranty – Many manufacturers require annual servicing to keep the warranty valid.
Now, let’s look at what a boiler service includes.
What Happens During a Boiler Service?
A professional heating engineer will carry out a thorough inspection and maintenance check of your boiler, following industry standards and manufacturer guidelines. Here’s what you can expect:
1. Visual Inspection
The engineer will begin with a visual assessment of the boiler and its surroundings. They will check for any obvious signs of leaks, corrosion, or damage. They’ll also inspect the pipework and flue to ensure everything is correctly installed and in good condition.
2. Boiler Casing Removal and Internal Checks
Next, the casing of the boiler is removed to access the internal components. The engineer will examine key parts, including:
- Heat exchanger – Checked for signs of wear, blockages, or cracks.
- Burner – Inspected and cleaned to ensure efficient combustion.
- Ignition system – Tested to confirm the boiler lights safely and reliably.
- Seals and joints – Assessed for leaks that could cause dangerous gas emissions.
3. Flue and Ventilation Inspection
The flue is a critical part of a boiler system as it removes harmful gases safely. The engineer will check for blockages, damage, or improper installation. They will also assess ventilation to ensure the boiler has sufficient airflow to operate correctly.
4. Gas Pressure and Flow Testing
To ensure your boiler is working efficiently, the engineer will test the gas pressure and flow rate. If the pressure is too low or too high, it can affect performance and safety. Any necessary adjustments will be made.
5. Combustion Analysis
Using a flue gas analyser, the engineer will measure the levels of carbon monoxide and other gases produced during combustion. This test confirms that the boiler is burning fuel efficiently and safely.
6. Cleaning of Key Components
Over time, boilers can accumulate dirt, debris, and limescale, which can affect performance. During the service, the engineer may clean the burner, heat exchanger, and other components to improve efficiency.
7. Safety Device Checks
Modern boilers have several built-in safety mechanisms, such as pressure relief valves and thermostats. The engineer will test these to ensure they are functioning correctly.
8. System Pressure and Water Flow Checks
The heating engineer will check the overall system pressure and ensure the water flow is operating as expected. If necessary, they will repressurise the system.
9. Final Testing and Boiler Restart
Once all checks and maintenance tasks are complete, the boiler will be reassembled, restarted, and tested to ensure it is functioning correctly. The engineer will also provide a report detailing their findings and any recommendations for repairs or improvements.
How Often Should You Service Your Boiler?
It’s recommended that you service your boiler annually to maintain efficiency, prevent unexpected breakdowns, and ensure safety. This is especially important as winter approaches when your heating system will be in constant use.
