I had a plumber round the other day who replaced my heat exchanger and said it was full of silt, he suggested that the system is flushed.
I have an Arriston condensing boiler, what is the procedure for flushing the system, do i just buy a bottle of central heating cleaner poor it into a radiator then put the heating on for a bit to let it circulate before draining and re-filling.
Or does the central heating cleaner have to go straight into the boilers cw flow ???
