Leaking Boiler

Do you've got a leaking boiler?

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

First we have to establish which kind of boiler you have, could it be a combination 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 there will be 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 know that may sound strange, but it's true. Each one of these boilers working under ruthless should 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 should have your boiler serviced each year without fail, if you decide not to have your boiler serviced then at sometime in the future you will have a pricey repair bill or even the cost of a new boiler.

So why could it be vital that you have your boiler serviced?

The times of not bothering to service your boiler have long gone, these boilers were very basic and not 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 one's fuel bill went of the flue and another 60% into you're heat.

Since 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 best performance and most of all save you on your energy bill.

Whenever a boiler service is carried out we have been 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 exterior as they should.

We take a combustion reading with a combustion analyser and be sure the boiler when running is at the boiler makers parameters, if the reading are not correct then we carry out further investigation to determine why, then reset.

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

The expansion vessel, The expansion vessel is really a very important section of your boiler and heat, if this isn't working properly you then 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 isn't a leaking boiler, it's an expansion vessel problem. https://www.scsplumbingandheating.co.uk/ needs 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 stop working.

The Boiler Service

When you call in your neighborhood gas safe registered boiler service engineer to service your boiler, ask him to be sure the expansion vessel is checked over and reset if needed. For reasons uknown whenever a boiler service is completed, the expansion vessel appears to be left out and not checked, not all of that time period but around 80% of that time period. When you browse the boiler makers instructions on boiler service they state that the expansion should be checked and reset if needed.

So what happens to the expansion vessel?

The simplest way to describe the expansion vessel is, its like a car tyre, as time passes it will eventually go flat. The vessel may be the same, it is pumped up with an automobile pump to a Pressure that is compatible to the sort of heating system you have.

If the vessel loses its pressure then it'll start 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 as it gets hotter within you're heat. If the vessel does not have any internal pressure then it will fill with water, once full, your boiler will then start to discharge water through the pressure relief valve, to release the pressure to stop pipes bursting.
