The annual boiler service is an extremely important job that's best done in the warmer months of the year, but did you know around 90% of us do not have the boiler serviced.
The boiler for some reason seems to get forgotten until something happens, you go to have a shower and find you have no hot water. Then you start to panic trying to find you to definitely repair the boiler.
So why is the annual boiler service important?
11 years back the high efficiency-condensing boiler became compulsory in the United Kingdom.
With the boilers before condensing it was not as important to have them serviced as it is now. The reason is that the boilers then did not have so many parts inside as they do in the current condensing boilers, yes they went wrong but were a lot easier and cheaper to correct, although it is definitely a recommendation by the boiler makers to really have the boiler and any gas appliance serviced annually.
It's more important now than previously with an annual boiler service and the boiler checked over to make sure it is performing as ought to be, and most important that it is SAFE.
Having an annual boiler service just about the most important checks is the flue pipe, it has to be checked to make certain all joints and seals aren't leaking carbon monoxide or products of combustion into the room the boiler is situated in.
The high efficiency or condensing boilers because they are known while running produce condense, this is an acidic water, because it is acidic, it can start to rot the flue-pipe, and should this happen the flue will start to leak products of combustion (carbon monoxide), which once we all know can be quite dangerous to life, this is the most important elements of the service.
All condensing boilers have a condense trap built in, this should be washed and checked for leakage it is also area of the boilers flue system.
When the boiler is running the water it produces cleans the combustion chamber of any residue and this ends up in the trap.
With many boilers of today they work under high pressure and also have an expansion vessel connected to the pipe work, this can be either internally or externally.
The expansion vessel will as time passes will lose pressure and will ought to be recharged to help keep the boiler working to it's full efficiently.
The expansion vessel is really a very important part of the annual boiler service that should be checked. After the vessel loses the charge it puts pressure on the pump, the inner water parts and the complete O rings within the boiler.
Have you ever noticed whenever your boiler is running that the pressure gauge either fitted on the boiler or on external pipe starts to go up when the boiler cools down the pressure drops down to zero. You may have noticed that the discharge pipe or overflow pipe as some individuals call it, is showing signs of water discharge. In case you have then this is normally an indication that the expansion vessel has lost its charge.
The main annual boiler service is to check the boiler combustion rate.
This is to make certain the boiler is burning gas as it was designed for, this is carried out using a flue gas analyser which is inserted in to the flue-pipe and a reading is taken, if the readings are within the boilers recommendations then no more action is required, if the readings are from the recommendations then further investigations are needed to obtain the problem.
With https://tsboilerservicing.co.uk/ of boiler the burners were removed and the flue-ways were cleaned and checked, but with the condensing boiler the flue-gas reading tells us once the burners need to be removed. In fact Vaillant boilers now say the burners may will never need to be removed if the boiler is established and maintained properly, they once suggested that the burners be removed every five years.
Having an annual boiler service they are just some of the checks that need to be completed, and because many boilers now include long warranties, to keep the boiler warranty valid you'll want an annual boiler service. After the service has been completed, then the engineer must date and sign the warranty booklet to keep the warranty valid.
I have spoken to many customers with long boiler warranties, and for some reason they appear to think they do not need an annual boiler service due to long warranty. This is not so, you must match the annual boiler service otherwise, in the event you need to make a claim under the warranty you may find you'll have a large repair bill, all as you failed to continue the annual boiler service.
One last thing before we finish, remember that any type of gas work, be it fitting your brand-new cooker, the annual boiler service whatever it could be has to be carried out by a Gas Safe Registered person. If they are not gas safe registered you then will have no warranty on the boiler & most important you can find your home insurance also becomes void should something happen.
