We have a Gas Boiler that was installed about 3 years ago when we had an extension to our house. The central heating system for the whole house was redesigned at that time by a CORGI approved engineer.
It has been regularly serviced since and is currently covered by a British Gas servicing contract.
Since we've switched the central heating on for the winter it has worked perfectly as far as heating the house is concerned, but despite bleeding the raidiators (when it's switched off) it is making a horrendous noise while it heats up the water. It sounds like the noise a young boy makes when pretending to be firing a gun (a sort of "peeyung, peeyung" sound). It's very loud - wakes us up in the morning. The sound continues for a short while if I switch off the heating.
Before we have the BG man in, I'd like an idea of what it's likely to be that is causing the problem. Just so that we don't get conned into buying a new system when it may be something simple.
TIA
Neil

It is usually a calcium deposit that slightly hardens at the bottom of the boiler and when you turn on the heat the water boils the water trapped under the deposit causing it to make a "burping" sound... Every year you should drain water out of the boiler to prevent this from happening...

It looks as though theres a bit of localised boiling, on a "hot spot" in the boiler, caused by a bit of muck or limescale. Get the engineer in - you probably pay about £240 a year, so you may as well get some value out of it!
In the meantime, set the timer so the boiler fires at getting-up time, and forget about setting the alarm clock.

It could be that you need to equalise the pressure in the boiler. My boiler has a tap which you can turn to let some water through and a gauge which shows you the pressure. The manual for the boiler said to keep it at 1.5bar, so i turned the tap till it went to that.

as i've said so many times before on this site don't listen to all the arseholes who think they knpw it all by reading up on some website or other, your answer is just like bigal says, ie, sentinel x200 pured into your c/h header tank should do the trick for kettling in your boiler , more so in hard water parts of the country.
go for it.

Drain water out of the boiler every year???? Good sales pitch mate,I bet your house is HUGE!! In 34 years of working for BG thats a new one on me as a cure for limescale.Try a treatment called Sentinel X200,instructions on the bottle,self-neutralising so no draining reqd,unfortunately for matey-boy no fee reqd

lime deposits could be moving inside the boiler hitting the sides,
