What is Boiler Service


A boiler service is an in-depth inspection and test of your boiler to ensure it is functioning both correctly and efficiently. These have to be carried out yearly throughout the life span of the boiler to maintain any warranty you may have. A boiler service should only be carried out by a Gas Safe engineer. Upon completion, you will receive a service certificate.



What to expect when your boiler is serviced?

Here are some key things that should take place during a boiler service, initially there will be a visual inspection, during which the engineer will check the boilers flame is on and look for any signs of corrosion or leaks amongst other things.

Following a visual inspection of the outside of the boiler, the engineer will then remove the casing of the boiler to gain a better idea of the condition inside the unit. At this point the main components of the boiler such as the heat exchanger, main injector and burner will be tested to ensure they are working correctly.

During service, the Engineer will also carry out various checks on the flue to make sure there are no blockages, and the flue is fitted correctly. They will also check the flue for any dangerous emissions that may be coming from the boiler.

In addition to the previously mentioned checks, a Gas Pressure check will be carried out to ensure gas is reaching the boiler at optimum pressure allowing everything to function as it should.

Finally, the boiler should be checked to ensure it is firing up correctly, pushing heat and hot water round the system.

If during any of these checks the boiler is found to be unsafe, the engineer is within their rights to shut the boiler down until the problems are rectified.


How often Should a boiler be Serviced?

As previously mentioned, boiler services should be carried out annually, like a health check for your heating system as this will allow you to catch problems early and extend the lifespan of your boiler. After all, in most cases, repairing is cheaper than replacing. So be sure to book yours in.
