Hi there. My radiator seems to make a noise like it is letting the hot water in, but when the radiator thermostat temperature is exceeded the noise of the water entering, still continues. I thought the water would stop when it reached the preset temperature. Other radiators with the same make of thermostat seem a lot quieter. Anyone know what causes this noise. As I said, it's just like water rushing into the radiator. No water leaking.
