I've had a problem with my boiler kettling, so its been switched off and i'm using the immersion. Had some pipes altered and the plumber back filled the system as the cold feed was blocked. I'm guessing then not much inhibitor got in the sytem causing scale to build up? Anyway I have cleaned out the tank, so its free of sludge and flushed the cold feed with a hose pipe. Seems to be ok now.
My question is do I add X100 + X200 togther in the tank? as I need to clear the scale. Or is it best to clear the sludge/scale, drain the system and refill with X100?
