Do https://tsboilerservicing.co.uk/ got a leaking boiler?
Assuming you have a boiler that you may think is leaking, but cannot see any type of leak, what now ??
First we need to 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 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 isn't always a leaking boiler, I know that might sound strange, but it's true. All these boilers working under ruthless must have an expansion vessel fitted either internally or externally, that is normally the cause of a leaking boiler.
Just how do we resolve the leaking boiler problem?
First you should 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 as well as the cost of a fresh boiler.
So why could it be important to have your boiler serviced?
The days of not bothering to service your boiler have long gone, these boilers were very basic and not much went wrong using them, the most common problem was that the thermal coupling had to be changed. These boilers were not very efficient around 40% of your fuel bill went 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 all save you on your energy bill.
When a boiler service is carried out we are looking first to be sure everything is still safe, there are no combustion or gas leaks, checking over 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 be sure the boiler when running is within the boiler makers parameters, if the reading are not correct then we perform further investigation to discover why, then reset.
Next we come to the most typical problem with these boilers.
The expansion vessel, The expansion vessel is really a very important part of your boiler and heating system, if this is not working properly then you will have problems. The most frequent problem could be the loss 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. The vessel has to be checked each year and reset for your boiler to give its best performance, once the vessel it not checked, as time passes it will stop working.
The Boiler Service
When you contact your local gas safe registered boiler service engineer to service your boiler, ask him to ensure the expansion vessel is checked over and reset if needed. For some reason when a boiler service is completed, the expansion vessel is apparently left out and not checked, not all of the time but around 80% of that time period. When you read the boiler makers instructions on boiler service they state that the expansion should be checked and reset if needed.
Just what exactly happens to the expansion vessel?
The easiest way to describe the expansion vessel is, its such as a car tyre, as time passes it will eventually go flat. The vessel is the same, it really is pumped up with a car pump to a Pressure that is compatible to the type of heating system you have.
If the vessel loses its pressure then it will start to fill with water internally, once this starts to occur most people start to think they could have a leaking boiler.
The expansion vessel functions by taking on the expansion of the water as it heats up within you're heating system. If the vessel has no internal pressure then it will fill with water, once full, your boiler will then begin to discharge water through the pressure relief valve, release a the pressure to avoid pipes bursting.
