We know the importance of them, but what exactly is involved in a boiler service? Essentially it is a series of checks and inspections carried out by a qualified boiler techinician to ensure your boiler is operating both safely and efficiently. Possibly the most important check is for the presence of CO (Carbon Monoxide) which will also involve confirming that your boiler installation is vented properly.
The boiler technician will also remove the casing of the boiler and check all the working parts inside, particularly the moving parts which will be more likely to suffer wear and tear. A further check will be to test the ignition and fuel supply, whilst also ensuring that fuel supply is cut off when the boiler isn’t in use. It’s also important that a boiler service isn’t confused with a ‘boiler check’, which is a far less comprehensive testing.
