The annual boiler service is a very important job that is best done in the warmer months of the entire year, but do you realize around 90% folks do not have the boiler serviced.

The boiler for reasons uknown appears to get forgotten until something happens, you go to have a shower and discover you have no warm water. Then you begin to panic trying to find you to definitely repair the boiler.

So why is https://srboilerservicing.co.uk/ ?

11 years ago the high efficiency-condensing boiler became compulsory in britain.

With the boilers before condensing it was not as important to have them serviced as it is now. Associated with 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 easier and cheaper to repair, 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 ever before with an annual boiler service and the boiler checked over to make sure it really is performing as should be, and most important that it is SAFE.

With an annual boiler service the most important checks may be the flue pipe, this has to be checked to be sure all joints and seals aren't leaking carbon monoxide or products of combustion in to the room the boiler is located in.

The high efficiency or condensing boilers as they are known while running produce condense, this is an acidic water, because it is acidic, it could start to corrode the flue-pipe, and should this happen the flue will start to leak products of combustion (carbon monoxide), which as we all know can be quite dangerous to life, this is one of the important parts 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 area of the boilers flue system.

When 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 high pressure and also have an expansion vessel linked to the pipe work, this is often either internally or externally.

The expansion vessel will over time will lose pressure and can must be recharged to keep the boiler attempting 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 strain on the pump, the internal water parts and the complete O rings within the boiler.

Perhaps you have noticed when your boiler is running that the pressure gauge either fitted on the boiler or on external pipe starts to go up then when the boiler cools down the pressure drops down to zero. You may have pointed out that the discharge pipe or overflow pipe as some people call it, is showing signs of water discharge. Should you have then this is normally a sign that the expansion vessel has lost its charge.

Part of the annual boiler service would be to check the boiler combustion rate.

This is to make sure the boiler is burning gas since it was designed for, that is carried out utilizing a flue gas analyser that is inserted into the flue-pipe and a reading is taken, if the readings are within the boilers recommendations then no further action is required, but if the readings are out of the recommendations then further investigations are needed to find the problem.

With the old type 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 have to be removed. In fact Vaillant boilers now say the burners may never need to be removed if the boiler is set up 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 completed, and because many boilers now include long warranties, to help keep the boiler warranty valid you must have an annual boiler service. Once the service has been carried out, then the engineer must date and sign the warranty booklet to keep the warranty valid.

I have spoken to numerous customers with long boiler warranties, and for reasons uknown they seem to think they don't need an annual boiler service as a result of long warranty. This is simply not so, you must match the annual boiler service otherwise, should you need to make a claim beneath the warranty you might find you will have a large repair bill, all as you failed to keep up the annual boiler service.

One very 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 completed by way of a Gas Safe Registered person. If they are not gas safe registered you then could have no warranty on the boiler & most important you will find your house insurance also becomes void should something happen.
