On older boilers, typically those more than 12 years old you should be able to check to see the pilot light and main burner flame.
There will normally be a see-through window or spy hole that
allows you to see the pilot flame and main burner.
Your boiler is working properly the flame of the pilot and the burner should be a nice crisp blue.
If it is burning a yellow colour, you’ll need to call out your local gas safe engineer.
To carry out a full service and check why the flame is not burning as it should.
The pilot light goes out, check the boilers manual to find out how to turn it back on again.
may have lost your copy, go online and do a search on google for your make of boiler,
you should be able to download a fresh copy.
On some of the later boilers, the pilot was automatic.
So if the boiler does not light, it means there is a problem and it will need to be investigated.
Once the flame reappears, you’ll most likely need to keep your finger on the gas
valve button pushed down for at least 30 seconds before releasing it.
Don’t to try and dismantle your boiler yourself,
all gas appliances have to be worked on by a Gas Safe Registered engineer.
Do not work on it and something goes wrong you will find that your home insurance will most likely be void.
also breaking the law.
On an open-vented system, if the pilot flame is lit, but you don’t have any heat or hot water,
may find the ball valve is stuck in the feed and expansion tank.
Typical symptoms include upstairs radiators being cold, and no air or water coming out of them if you try to bleed them.
The circulation pump may also be particularly noisy.
Go to the feed and expansion tank (normally next to your cold water tank) and find it is empty.
Try moving the ball valve up and down.
The valve should start working again, and the feed and expansion tank should start to fill up.
Still don’t get any air or water from them, you will need to call in your local gas safe engineer.
What happens is a common fault on the open vented system,
the cold feed and vent pipe get blocked with sludge.
This needs to be cut out and replaced.
Once that has been done it’s a good idea to have your system cleaned
out and an inhibitor added to prevent it from happening again.
Inhibitor within the system should be checked every year,
as with an open vented system, the water over time evaporates up the open vent pipe.
Older, open-vented non-condensing boilers take air in from inside your home.
Whereas newer, sealed condensing systems take air directly from outside.
This means that a newer sealed condensing boiler
will normally take in cleaner air and be better at retaining energy.
A new sealed condensing boiler will be at least 30% more efficient than an older non-condensing type.
find that your water and heating will heat up a lot quicker than before.
When your engineer arrives ask to see his gas safe card and check the back of it as well, if he is going to be working on your boiler make sure he has boilers on the card.
Only has cookers on the card then he cannot work on boilers.
