This sounds like "kettling". This is due to sludge forming a hard crust in the base of the boiler that traps water in pockets. This leads to localised boiling where the flame impinges on the underside of the heat exchanger. The trapped steam forces its way out to other parts of the boiler causing hissing and sometimes knocking as it does so. In extreme cases it sounds like small explosions. The whole system should be properly flushed out with an appropriate chemical treatment and equipment. The system is then refilled with an inhibitor which should prevent further silting up of the system. The sludge can lead to reduced efficiency in the radiators and possibly corrosion and leakage. This treatment should be done by a professional.

I've done it once,
Pick the radiator you think will be the first to heat up and open the pressure release valve (ussually on the right) Note; DON'T REMOVE THE
VALVE. If you do the air will come but at a moments notice you will also
have hot water being pushed out, making it impossible to put back the valve.
Then have someone turn the thermostat up just a few degress just enough
to get the boiler working.Listen to the air being released, when you spot water
shut the valve. If something goes wrong' shout out, SHUT THE BOILLER ! And correct the problem and continue to the next raidiator. You'll do find.

Sounds to me like kettle. Its small pockets of water that are stationary in the boiler and actually boil even tho the system may be well below boiling point It can become apparent after only a few minutes running . Try some Fairy liquid in the system about an egg cup full in a radiator. To do this turn both radiator valves off, If you have radiators with large nuts in the top tapping's then just remove one and crack a joint at a valve connection to drain some water out. . Squirt fairy liquid in and replace the plug. Tighten the valve joint and turn on the valves turn the heating on now listen to the noise disappear.
If no plug at the top then remove vent screw and squirt f/l in vent hole releasing water from valve joint.

It could be that the silencer on the burner is faulty. The main burner of the back boiler has a silencer fitted over the gmain gas jet. the burner is very noisy if there is a fault with it. It is not easy for a DIY job and I suggest that you contact a heating engineer because he will need to remove the back boiler to put it right.

the berbuda is complex and you should call a plumber and get it properly serviced, maybe your insurance will cover this

if you have radiators they may need bleeding, you can get a key from any diy shop.
