I have an upstaird radiator that makes a constant humming noise, similar to that of a computer with a loud fan. No other radiator in the house (including upstairs) makes the same noise. The radiatore makes the same noise whether it is on or off. I've bled the radiator, making no difference, and the noise even continues when the valve is open.
Please help, as it's driving me daft. If you need more info, please let me know.
Thanks.
