The concentrated area with high stress works as anode and diluted area works as cathode. At anode, sodium hydroxide attacks the surrounding material and then dissolves the iron of the boiler as sodium ferrate forming rust. This causes embrittlement of boiler parts like rivets, bends and joints, which are under stress.
One advantage of a boiler is that the furnace can provide hot water for bathing and washing dishes, rather than requiring a separate water heater.
