Why you should Have an Annual Boiler Service

The annual Boiler Service is a very important job that is best done in the warmer months of the year, but did you know around 90% of us do not have the Boiler Service d.

The combi boiler for reasons uknown generally seems to get forgotten until something boiler service near me happens, you go to have a shower and discover you have no domestic hot water. Then you start to panic trying to find you to definitely repair the combi boiler.

So just why is the annual Boiler Service important?

11 years ago the high efficiency-condensing combi boiler became mandatory in the united kingdom.

With the boilers before condensing it was less important to ask them to serviced as it is now. This is because 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 repair, although it has always been a recommendation by the combi boiler makers to have combi boiler and any gas appliance serviced annually.

It's more important now than previously to have an annual Boiler Service and the combi boiler checked over to make sure it is performing as should be, and most important that it's SAFE.

With an annual Boiler Service one of the most important checks is the flue tube, this has to be checked to make sure all joints and elephant seals are not leaking carbon dioxide monoxide or products of combustion into the room the combi boiler is situated 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 can start to corrode the flue-pipe, and may this happen the flue will begin to trickle products of combustion (carbon monoxide), which as we all know can be very dangerous our health, this is one of the most important parts of the service.

All condensing boilers have a condense trap built in, this needs to be cleansed and checked for loss it's also organ of the boilers flue system.

When the combi boiler is running the water it produces clears the combustion chamber of any remains and this results in the trap.

With many boilers of today they work under questionable and have an expansion vessel linked to the tube work, this can be either internally or outside the body.

The expansion vessel will over time will lose pressure and will need to be energized to keep the combi boiler attempting to it's full efficiently.

The expansion vessel is a very important organ of the annual Boiler Service that needs to be checked. Once the vessel seems to lose the charge it puts pressure on the pump, the inner water parts and the entire A rings within the combi boiler.

Have you ever noticed when your combi boiler is running that the pressure gauge either fitted on the combi boiler or on external tube starts to rise finding the combi boiler cools down the pressure droplets down to zero. You may even have pointed out that the discharge tube or overflow tube as some people call it, is showing signs of water discharge. If you have then this is normally an indication that the expansion vessel has lost its charge.

Organ of the annual Boiler Service is to check the combi boiler combustion rate.

This is to make sure the combi 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 parts are within the boilers recommendations then no further action is required, if the parts are out of the recommendations then further investigations are expected to find the problem.

With the old type of combi boiler the burners were removed and the flue-ways were cleaned and checked, but with the condensing combi boiler the flue-gas reading tells us when the burners need to be removed. In fact Vaillant boilers now say the burners may never need to be removed if the combi boiler is defined up and maintained properly, they once suggested that the burners be removed every five years.

With an annual Boiler Service these are are just some of the checks that need to be carried out, and because many boilers now come with long extended warranties, to keep the combi boiler warranty valid you must have an annual Boiler Service. Once the service has been carried out, then the manufacture needs to date and sign the warranty book to keep the warranty valid.

I have spoke to many customers with long combi boiler extended warranties, and for reasons uknown they find a way to think they just do not need an annual Boiler Service because of the long warranty. This is not so, you must maintain the annual Boiler Service otherwise, should you need to make a claim under the warranty you may find you will have a large repair bill, all because you failed to maintain the annual Boiler Service.

One final thing before we finish, bear in mind that any form of gas work, be it fitting your new pot, the annual Boiler Service whatever it may be has to be carried out by a Gas Safe Registered person. If they are not gas safe registered then you will have no warranty on the combi boiler and most important you will find your home insurance also becomes void should something happen.
