A bathroom radiator is quite rusty underneath and I think needs replacing. Also, our living room radiator needs bleeding fairly regularly, so I assume there is some corrosion inside and that might need replacing too.
If two radiators (or maybe more!) are to be replaced, I assume that the system would need to be drained as well, so a flush might be best left until that's done. I hope I'm right!
Hope you're keeping well, by the way.
Thanks JBR, however, I cannot take the credit for the write-up. It was written by a friend of mine from the 'dark side
) If you are having to bleed the living room rad frequently, it
could indicate a system fault. If you have an open-vented system, check the small expansion tank in the loft. How dirty is the water? Does it have a lid on the tank? (it should have to stop the ingress of debris - therefore, not getting into your system) I would suggest if you are replacing all of the radiators, then drain and flush the system. Then, you can add a flushing agent according to the manufacturers instructions.
We are both well mate and might be able to take a trip oop North later in the year
