Leaking Boiler

Do you've got a leaking boiler?

Assuming you have a boiler that you may think is leaking, but cannot see any form of leak, what do you do?

First we must establish what sort 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're sometimes are pressurised, or work under low pressure.

With all boilers that are pressurised you will have a pressure gauge suited to either the front of the boiler or near by on the pipe work.

A leaking boiler isn't always a leaking boiler, I understand that may sound strange, but it's true. All these boilers working under high pressure should have an expansion vessel fitted either internally or externally, this is normally the reason for a leaking boiler.

Just how do we resolve the leaking boiler problem?

First you should have your boiler serviced each year without fail, in the event that you decide never to have your boiler serviced then at sometime in the foreseeable future you will have a pricey repair bill and even the cost of a fresh boiler.

So why is it important to have your boiler serviced?

The times of not bothering to service your boiler have long gone, these boilers were very basic rather than much went wrong using them, the most typical problem was that the thermal coupling had to be changed. These boilers were not 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 has been very important to possess them serviced every year. These boilers are designed to give the very best performance and most of all save you on your own energy bill.

When a boiler service is carried out we are looking first to make certain everything is still safe, that there are no combustion or gas leaks, checking on the flue making sure the product of combustion are exiting to the outside as they should.

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

Next we arrived at the most frequent problem with one of these boilers.

The expansion vessel, The expansion vessel is a very important section of your boiler and heat, if this isn't working properly then you will have problems. https://www.ljbheatingandplumbing.co.uk/ is definitely the loss of system pressure, a lot of people describe this as a leaking boiler.

In fact it's not a leaking boiler, it's an expansion vessel problem. The vessel needs to be checked each year and reset for the boiler to give its best performance, when the vessel it not checked, as time passes it will stop working.

The Boiler Service

When you contact your neighborhood 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 that time period but around 80% of that time period. When you read 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 ultimate way to describe the expansion vessel is, its such as a car tyre, over time it will eventually go flat. The vessel is the same, it really is pumped up with an automobile pump to a Pressure that is 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 begin to think they may have a leaking boiler.

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