From time to time I get a loud throbbing noise coming from a group of 3 radiators. If I turn the thermostatic valve up slightly on one of them, the noise disappears - but usually returns a bit later. Occasionally, turning one of the valves down slightly can also stop it (this only applies to one particular radiator).
My central heating pump has 3 speeds. It's currently set on speed 1 (lowest). If you turn it up to speed 2 then you get the throbbing almost immediately.
Any help/advice gratefully appreciated.
Thanks.
