boiler repairs rotherham for some purpose appears to get forgotten until a thing occurs, you go to have a shower and locate you have no hot water. Then you get started to panic trying to come across an individual to repair the boiler.

So why is the annual boiler service crucial?

11 years ago the higher efficiency-condensing boiler became compulsory in the United Kingdom.

With the boilers just before condensing it was not as critical to have them serviced as it is now. The purpose is that the boilers then did not have so many components inside as they do in today’s condensing boilers, yes they went wrong but were a lot a lot easier and more affordable to repair, even though it has normally been a recommendation by the boiler makers to have the boiler and any gas appliance serviced annually.


It really is far more important now than ever prior to to have an annual boiler service and the boiler checked over to make positive it is performing as should be, and most vital that it really is Secure.

With an annual boiler service a single of the most crucial checks is the flue pipe, this has to be checked to make certain all joints and seals are not leaking carbon monoxide or items of combustion into the space the boiler is positioned in.

The high efficiency or condensing boilers as they are identified whilst operating make condense, this is an acidic water, since it is acidic, it can commence to corrode the flue-pipe, and really should this happen the flue will begin to leak solutions of combustion (carbon monoxide), which as we all know can be pretty unsafe to life, this is a single of the most critical parts of the service.

All condensing boilers have a condense trap built in, this wants to be cleaned out and checked for leakage it is also element 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 a lot of boilers of right now they work beneath higher pressure and have an expansion vessel connected to the pipe perform, this can be either internally or externally.

The expansion vessel will over time will lose stress and will require to be recharged to preserve the boiler working to it really is complete effectively.

The expansion vessel is a really crucial portion of the annual boiler service that wants to be checked. As soon as the vessel loses the charge it puts pressure on the pump, the internal water parts and the whole O rings inside the boiler.

Have you ever noticed when your boiler is running that the stress gauge either fitted on the boiler or on external pipe starts to rise then when the boiler cools down the pressure drops down to zero. You could even have noticed that the discharge pipe or overflow pipe as some persons call it, is showing indicators of water discharge. If you have then this is typically an indication that the expansion vessel has lost its charge.

Element of the annual boiler service is to verify the boiler combustion price.

This is to make confident the boiler is burning gas as it was developed 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 inside the boilers suggestions then no further action is necessary, but if the readings are out of the suggestions then additional investigations are necessary to obtain the problem.

With the old variety of boiler the burners were removed and the flue-approaches had been cleaned and checked, but with the condensing boiler the flue-gas reading tells us when the burners want to be removed. In fact Vaillant boilers now say the burners may well under no circumstances want to be removed if the boiler is set up and maintained properly, they when suggested that the burners be removed every single five years.

With an annual boiler service these are just a few of the checks that will need to be carried out, and for the reason that quite a few boilers now come with lengthy warranties, to retain the boiler warranty valid you will have to have an annual boiler service. When the service has been carried out, then the engineer requires to date and sign the warranty booklet to preserve the warranty valid.

I have spoken to several customers with extended boiler warranties, and for some reason they seem to feel they do not need to have an annual boiler service due to the fact of the long warranty. This is not so, you must retain up with the annual boiler service otherwise, should really you need to make a claim under the warranty you may well locate you will have a massive repair bill, all simply because you failed to keep up the annual boiler service.
