Thanks for help. The Expansion vessel had no pressure. However having corrected this the problem did not go away. The reason being A BLOCKED FLEXI PIPE TO EXPANSION VESSEL!!.

Thanks for advice everyone. I will try suggestions today and report back.

Help, The pressure gauge on my Britony combi rises from 0.5 bar to 3 bar in under 30 minutes when the central heating is on, at this point the pressure relief valve kicks in. Is the expansion vessel faulty, or maybe need repressurising. Can I do this myself and if so How? Thanks for any help...

I have cleansed the system and the boiler is now quiet. Thanks for the advice. :P

Thanks for the advice. I ran the hot water as suggested and the noise started up as per usual, I then shut off the gas and the noise stopped instantly. From what you suggested it must be the heat exchanger. How much for a new one? Any other remedy? Thanks. :P

Thanks for the advice, I will report back!. :P

Thanks for all the bits of advice, I will try it out and report back. :P

The problem started a couple of months ago and has steadily got worse. The noise happens on all hot water taps and gets worse if you slow the flow down to get hotter water. :P

Yes the water is hot but the boiler is extremely noisy, it sounds just like a hammer drill.

I have a problem with a 3 year old Britony Combi. It works fine in Central Heating Mode but in Hot water mode the boiler sounds like a hammer drill going off, it is extremely noisy. I have tried adding chemicals to silence the boiler but this does not work. Any ideas please :P
