Not only is it not necessary to regulate the temperature when boiling water, it is impossible. The temperature will be exactly the boiling point of water at that altitude, if slightly lower it will not be boiling, and it is not possible to get hotter until the water is gone.

As far as other solvents vaporizing at any certain temperature, each will have their own vapor pressure. The higher the vapor pressure, the more will be in the steam, the lower, the less in the stream. When distilling water any compounds that vaporize will be in the steam.

The better distillers will have very precise temperature controls. The boiling point of water changes with changes in altitude. So if you know what temperature your water boils, you want the temperature of the water to be confined to the narrowest tolerance possible. This will ensure that H2O will be evaporated.

    Hi Chaps,

    My thoughts have been that anything that will vapourise at temps
    lower than the boiling point of water will also rise, cool and
    condense thereby polluting the end product.

    My solution to this is to let the water boil for a good 15 mins
    first to allow the contaminants to release into the air, and then
    I place the condenser unit on top and start collecting. *please do
    that carefully*.

    Even then needless to say.... double distill in this manner for
    excellent results.

    Emphasis on the double distill.......

    Peace and love to all,

    Asif.

    Hi Melly...the many different designs  of  water distillationunits
    that are available will all  produce clean safe water.
    I  doubt that any of the pollution will  carry over in the water
    vapour (steam) that is cooled to reform the distilledproduct.
    Please could anyoone corrector  confirm that?
    thanks
    Tara

        Olukashola,



        How can rainwater nowadays be clean, with depleted uranium in the
        atmosphere
        hovering perpetually and comes down on us when it rains?

        Our atmosphere is also full of Fukushima radiation which also
        comes down in
        the water.  We have to be realistic, our water, land and air
        is slowly

        poisoning us.  Do our present available filters remove DU and
        radiation?
        Please anyone know if filters work on above pollutants?
