Leaking heat exchangers required fresh water to be added to the boiler water to make up for that lost, carrying along with it oxygen and chlorine. Both will accelerate corrosion, so the water treatment process needs to remove air (with its oxygen) and chlorine, from the fresh water makeup in returning condensate before it enters the boiler.
