Resonating radiator

I was sitting at my desk and suddenly the radiator sprang into life. Took me some time to locate the source of the buzz but definitely the radiator. Strange since we don't use the radiators anymore. Not since we got the heat pump.

I recorded the buzz with my iphone.

So, why was it buzzing?

I recorded this from the other side of the house
