    A friend has just bought a flat which has two radiators out of four that are hot at top and cold at the bottom. They look fairly old and show signs of rust on the outside which has been painted over.

    Rather than get them flushed through would it be better just to replace them?

    sounds like they may be sludged up. i would replace if were you, not worth messing about with flushing them if already rusting

    If two rads are in a bad state the chances are they all will be pretty ropey. As radiators (unless really large or ornate!) don't cost that mush I'd replace the whole lot and drain and refill the system with a good quality inhibitor added.

    Thanks for the responses. The radiators will be replaced, etc.
