I have a Baxi Bermuda S gas boiler and just recently it has started making a rumbling noise when the gas burner is on. It sounds similar to the noise you get from a blow torch when it’s just been lit and isn’t burning smoothly. The noise happens ONLY when the burner is lit. It also doesn’t happen the whole time, it’s intermittent, happening only a couple of times each evening. Any suggestions?
Many thanks for any useful info.
Kind regards

- Combi boiler pressure drops below 0 overnight and rises over 3 when on?
I’ve got a pretty new Heatline Vizo Condensing Combi Boiler. Everything was fine for the first couple of months and pressure held steady at 1.5 when cold, and rose to around 2 when the heating was on. Over the past few weeks, the water pressure drops below 0 turning the boiler off regularly. I can refill to 1.5 before going to bed, and it will be back below 0 in the morning. When I refill to 1.5 and have the heating on, the boiler pressure now rises to the maximum of 3. When the heating turns off, the pressure will drop again, eventually to below 0 within the space of maybe 8 or 9 hours. Whats going on? I cant find any obvious leaks (although the plumbing is underfloor), and there is no air in any of the rads. Ive drained and refilled the entire system a couple of times, but this has made no difference.… Read the rest...

Air in it somewhere – bleed all the radiators and it will stop
get a certified professional in

good luck
Sounds as if the burner needs cleaning, get in a qualified gas engineer to service the boiler. It is prudent to do this annually anyway.
In the UK only corgi registered gas fitters / plumbers can do this legally. I you do it yourself and the thing does go bang your insurance won’t cover any damage.
could be gas pressure to boiler, gas valve sticking, or overheat stat. In any of the above cases, call a corgi registered engineer to have a look and diagnose the problem
check with a corgi registered fitter.
Get it serviced sounds like its back lighting on the burner.
