Our combi boiler sounds like a fog horn

[stony]

Ever since we moved in it's occasionally done this every few hours or so. This last week has been fucking unbearable, we've even had to turn the heating off at night because it was keeping us and the neighbours up.
We had our yearly gas check and boiler service earlier in the week and we mentioned it the blokes who didn't have a clue and wasn't that fucking interested tbh.
When it goes off, it lasts for anything from a couple of seconds to almost a minute. I'm hope the plumbing and heating gurus on bm can identify the problem, and no, I don't know what make of boiler it is.
It's going off about 3 times an hour. On the plus side, at least when it's foggy we would be safe from passing oil tankers, even if we are about 60 fucking miles inland.

Impossible mate. Curry is banned in my house.

Boiler or pipes making the noise? Or a radiator thermostat valve? Does it do it on higher or lower temperature settings (the control on the boiler not the room stat)?

Maybe it's on the domestic hot water circuit. When it happens try running a hot tap (or cold tap).

At least you might narrow down possible causes.

At some point in this thread the advice will be "brick the windows and set fire to the house and claim on the insurance ".

I deliberately made the thread when I thought @aguero93:20 might be in bed.

We have the heating set on a constant 19 degrees. Running the hot water doesn't make a difference. It we start it up from cold it takes about 30 minutes before it starts making the noise, so the temp doesn't seem to matter.

Get the same sort of noise sometimes when I turn the cold water tap on in the bathroom. I looked it up and it seems it's more common with hot taps but it seems it might be something to do with a valve somewhere.

When they came and serviced the boiler he turned down the temp on the boiler and said it might make a difference. Tbf it has, it's made it worse.
