Leaking Boiler

Do  https://www.ljbheatingandplumbing.co.uk/  got a leaking boiler?

In case you have a boiler that you might think is leaking, but cannot see any form of leak, what do you do?

First we have to establish what type of boiler you have, could it be a mix boiler, system boiler or heat only boiler.

With combination and system boilers they work under ruthless, with heat only boilers they are sometimes are pressurised, or work under low pressure.

With all boilers which are pressurised you will see a pressure gauge suited to either leading of the boiler or near by on the pipe work.

A leaking boiler is not always a leaking boiler, I understand that may sound strange, but it's true. Each one of these boilers working under ruthless must have an expansion vessel fitted either internally or externally, this is normally the reason for a leaking boiler.

So how do we resolve the leaking boiler problem?

First you ought to have your boiler serviced each and every year without fail, in the event that you decide not to have your boiler serviced then at sometime in the foreseeable future you will have an expensive repair bill or even the cost of a new boiler.

So why could it be important to have your boiler serviced?

The times of not bothering to service your boiler have over, these boilers were very basic and not much went wrong with them, the most common problem was that the thermal coupling had to be changed. These boilers weren't very efficient around 40% of your fuel bill went out of the flue and the other 60% into you're heating system.

Because the introduction of the high efficiency condensing boilers it's been very important to possess them serviced every year. These boilers are designed to give the very best performance and most of most save you on your energy bill.

Whenever a boiler service is completed we are looking first to make sure everything is still safe, there are no combustion or gas leaks, checking on the flue making sure the merchandise of combustion are exiting to the exterior as they should.

We have a combustion reading with a combustion analyser and check that the boiler when running is within the boiler makers parameters, if the reading are not correct then we perform further investigation to find out why, then reset.

Next we arrived at the most typical problem with these boilers.

The expansion vessel, The expansion vessel is a very important section of your boiler and heat, if this is not working properly then you will have problems. The most frequent problem will be the lack of system pressure, most people describe this as a leaking boiler.

In fact it's not a leaking boiler, it's an expansion vessel problem. The vessel has to be checked every year and reset for your boiler to provide its best performance, when the vessel it not checked, as time passes it will go wrong.

The Boiler Service

When you call in your local gas safe registered boiler service engineer to service your boiler, ask him to make sure the expansion vessel is checked over and reset if needed. For some reason whenever a boiler service is carried out, the expansion vessel appears to be left out rather than checked, not all of the time but around 80% of that time period. When you browse the boiler makers instructions on boiler service they say that the expansion ought to be checked and reset if needed.

So what happens to the expansion vessel?

The best way to describe the expansion vessel is, its such as a car tyre, over time it is going to go flat. The vessel is the same, it really is pumped up with an automobile pump to a Pressure that's compatible to the sort of heat you have.

If the vessel loses its pressure then it will begin to fill with water internally, once this starts to happen most people start to think they may have a leaking boiler.

The expansion vessel works by taking up the expansion of the water since it heats up within you're heating system. If the vessel does not have any internal pressure then it will fill with water, once full, your boiler will begin to discharge water through the pressure relief valve, to release the pressure to stop pipes bursting.
