Boiler System Corrosion

Domestic boilers and their radiators are made out of quite thin metals, so there is a need to take great precautions as to the way they are treated more inside than out. The life expectancy of a boiler can be lessened to just a few years, however there are actions that can be taken. Corrosion can be down to hard-water deposits or even a chemical reaction between the water and the system’s metallic components. Acton Plumbers are tradesmen who know corrosion.Some Examples are below:Black Sludge:Something called magnetite or (black sludge) creates clogging inside the circulating pump and forms and settles in the bottom of radiators. The sludge degrades the output of heat form the radiator quite dramatically.Rusting:This coating is well known throughout most homes as the main product of corrosion. It will corrode its way through steel components, like all radiators. The majority of rusting happens within just a few weeks of filling a central heating system, and also if any air is finding its way in, then, rusting will be quite rapid and comprehensive. If a radiator or radiators need to be bled many times, then that is a strong clue that there is air getting in. An Acton Plumber is trained to find and treat rust.Lime Scale:The build up of lime scale usually occurs in the regions of UK that are known as hard water areas. It only takes a thin layer of lime scale on the inner wall of a boiler’s heater to have a reducing affect on its efficiency and is most times a contributing factor of bangs and knocks that can be heard inside the system. This scale covering can form an insulator in some sections of the heat exchanger in some cases to an extent that it forms ‘hotspots’, which will cause early failure of components.Electrolytic Action.Two metals that are dissimilar, like copper and aluminium are acted upon by what is known as an electrolyte, a name by which water is also known. This reaction creates electron flow from one metal to the other that starts to break them down and rot them, so it is good practice therefore to fit or have fitted an anode that will rot before the metals.
