    Came across this word in the Hymer manual about care of the Truma boiler..

    what exactly does the following sentence mean ?


    The boiler is protected against calcination if it is only used in maximum temperature position when a lot of warm water is used ..


    Does it mean that using at a high temperature protects against calcium deposits .. i.e. scale forming ?


    I think it's a translation glitch and it should read "calcium" .. not calcination..


    Calcination definition in Wiki :-

    Calcination

    Authorities differ on the meaning of calcination (also referred to as calcining). The IUPAC defines it as 'Heating to high temperatures in air or oxygen'.[1] However calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature processing (550-1150 °C, or 1000-2100 °F) within a controlled atmosphere.[2]

    I think it means you will get less lime scale if you have the hot water temperature set low, that is "warm". It is heating water to higher temperatures which cause the calcium to come out of the water. This is the process I think they call calcination, or in our language, lime scale forming.

    It makes sense at one level, don't have hot water and you won't get timescale. Not much use for a shower I think.

    It is possible what they say is correct, in that if there is timescale flushing a lot of water through the system when the system is set to warm only might dissolve the timescale. I've not heard of that but it might work I guess. Carefully using a descaler would be easier.
