What happens during a boiler service in London

Boiler Servicing? I’d rather let them do their thing! If you have been thinking this way you would want to read on. You can Thank me later

To schedule your periodic boiler servicing could slip your mind since enough importance is often not given to this. An annual boiler service session is highly vital to keep your boilers running smoothly and efficiently and preventing internal parts from rusting off.

As much as an annual boiler service is required, you should also be aware of the servicing procedure. You may think it is not something you need to know or that it might be all technical procedures that you will probably not understand. It would help you understand how a regular maintenance should be done while using boilers if you have an idea on the steps involved in a boiler servicing session. It would also help prevent any hazardous events such as carbon monoxide poisoning from occurring, if you know to detect a possible leakage. In addition to this, it would help those who have been ignoring the annual servicing sessions, from understanding how efficient a serviced boiler works and how much they are saving in the long run!! Now you wouldn’t say No to that! Would you?

Let us look at some of the main procedures involved in boiler service in London:

1. Initial Inspection


During the initial inspection, Gas Safety Engineers thoroughly analyse the gas boilers and check for any possible leakage or corrosion in the internal parts. They spend enough time observing the internal set up carefully because this step is vital in detecting what needs a replacement and what parts need a refurbishment during the servicing. Not only this, they also check for any faulty switches or button lights on the exterior of the boiler. They note down the damages and at this point they would inform you of any additional costs that may be involved due to a need for replacement of any parts.


2. Radiator, Pressure and Safety Check

This is a crucial step and should not be missed. This is why choosing a gas safety certified engineer to check your equipment is very important. They work as per certain guidelines and also offer you a service report at the end. During this step the radiators are checked for proper functioning. The pressure is then checked and refilled if required. Then all safety components are checked if functioning as per the model’s catalogue and the general gas safety certificate checklist.

3. Flue Test

A flue test would ensure if any poisonous emissions such as carbon monoxide leakages are present or possible in the future. Readings are taken to note that the flue joints are operating safely.


4. Controls. Burners and Leak Sealing

All controls or switches are checked and oiled if needed. Then the burners would be fixed to produce the optimal flame/heat emission. If ignition components are damaged they are replaced with new ones. A leak check is done at this point to ensure all outlets are sealed completely and no future leakages could occur. This step is done twice to ensure surety. All fan belts are checked and belt tension is adjusted.


5. Final Boiler Service Report

When your boiler is completely serviced and all parts including the case is fixed back on and sealed completely, the gas safety engineer would hand over a Service report that should ideally outline all the steps they have carried out and replacements and additional cost for the same if any. You should have a fair idea of what goes on in a typical boiler servicing session for you to ensure that your boiler has been in good hands and is in perfect condition post the servicing. At this point you can ask any queries from the engineers if you may have any doubts. Our engineers are always ready to clear your doubts and give you tips on proper maintenance of the boilers for a long and safe usage until they meet you again the following year.
