As I have pointed out in the past, flushing a system without removing and flushing each radiator both ways is not always going to achieve a clean system. Even with a clever power flush pump, its a waste of time for little result and the sediment will still be there. Acid flush such as DS1 will not dissolve all sediments found in central heating systems. Its fine for cleaning a new system when it is first completed but an old system requires some physical effort.
A complete new system installed with plastic pipe and fittings, new clean boiler and good quality clean radiators will only require a flush to remove any "bits" and oils, as there will be no flux or sealing compounds.
