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 never have the boiler serviced
 
 The boiler for reasons uknown appears to get forgotten until something happens, you head to have a shower and discover you have no warm water Then you start to panic trying to find someone to repair the boiler
 
 So why may be the annual boiler service important
 
 11 years ago the high efficiency-condensing boiler became compulsory in the United Kingdom
 
 With the boilers before condensing it had been not as important to have them serviced since it is now  https//wwwscsplumbingandheatingcouk/  is that the boilers then didn't have so many parts inside as they do in the current condensing boilers, yes they went wrong but were easier and cheaper to correct, although it has always been a recommendation by the boiler makers to have the boiler and any gas appliance serviced annually
 
 It's more important now than previously to have an annual boiler service and the boiler checked over to make sure it is performing as should be, and most important that it's SAFE
 
 Having an annual boiler service one of the most important checks may be the flue pipe, it has to be checked to be sure all joints and seals are not leaking carbon monoxide or products of combustion in to the room the boiler is situated in
 
 The high efficiency or condensing boilers because they are known while running produce condense, that is an acidic water, because it is acidic, it can start to corrode the flue-pipe, and should this happen the flue will begin to leak products of combustion carbon monoxide, which once we all know can be extremely dangerous to life, that is probably the most important elements of the service
 
 All condensing boilers have a condense trap built in, this needs to be cleaned out and checked for leakage it is also the main boilers flue system

 Once the boiler is running the water it produces cleans the combustion chamber of any residue which ends up in the trap
 
 With many boilers of today they work under ruthless 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 can must be recharged to 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 internal water parts and the complete O rings within the boiler
 
 Maybe you have noticed when your boiler is running that the pressure gauge either fitted on the boiler or on external pipe starts to rise when the boiler cools down the pressure drops down to zero You may even have pointed out that the discharge pipe or overflow pipe as some individuals call it, is showing signs of water discharge Should 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 ensure the boiler is burning gas as it was designed for, this is carried out using a flue gas analyser which is inserted into the flue-pipe and a reading is taken, if the readings are within the boilers recommendations then no more action is required, but if the readings are out from the recommendations then further investigations are essential to obtain the problem
 
 With the old kind 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 when the burners ought 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
 
 With an annual boiler service they are just some of the checks that need to be carried out, and because many boilers now come with 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 help keep the warranty valid
 
 I have spoken to numerous customers with long boiler warranties, and for some reason they seem to think they do not need an annual boiler service because of the long warranty This is simply not so, you must keep up with the annual boiler service otherwise, should you need to make a claim under the warranty you might find you will have a large repair bill, all as you failed to continue the annual boiler service
 
 One very last thing before we finish, don't forget that any type of gas work, be it fitting your brand-new cooker, the annual boiler service whatever it can be has to be carried out by a Gas Safe Registered person If they're not gas safe registered you then will have no warranty on the boiler amp; most important you can find your home insurance also becomes void should something happen
