Sometimes when you get a 'buzzing noise' coming from the breaker, it could be an indication that the breaker may be overloaded slightly.

What breaker is the storage heater on, and what is the power rating??

Ive had it on a lighting circuit(6 amp mcb) -loud vibrating/buzz. Im going to swap it out as i can only see a vibration as a cause of heat in future. The mcb was under hardly any load. Its a new fault to me so cant explain why....

The breaker is a B6. It only switches the timer on. I have two storage heaters. One is 2.5kw, the other is 3.5kw. Thanks for help by the way.
