  • Boilers and rainwater

    Hi there CSs!

    I own a sylvia and use tank (rain) water in it... we dont have the luxury of a reticulated water supply down here.
    Any thoughts on how often descaling is necessary (if at all) when using rainwater?

    Cheers,

    Miguel.

    Re: Boilers and rainwater

    Interesting one. Rainwater should be free of calcium and lime deposits which come from groundwater. There are contaminants in the atmosphere which rain dissolves as it falls through them (industrial pollution in the cities).

    That should not be an issue in the clean country air.

    Do you need to de-scale? If you have an electric jug which has been fed rain water only, look at the bottom of it and the element. If you see a rusty deposit, the answer is yes, you do have to descale.

    But it would seem to be unlikely.

      Hi Farmer Joe

      I have a Faema Family and a rain-water tank. Its a pretty rough tank and Im not all that conscientious about removing dead leaves etc from the filter-plate, yet I certainly dont have the problems people have in cities. Nonetheless I feel I still get a certain amount of mineral build-up judging from the old electric kettle. Its black residue and only comes away easily with acid (straight lime juice), so Im guessing its mineral rather than vegetable. Robustos idea of monitoring your kettle is pretty spot-on.

        Yes I too go with monitoring the electric jug in terms of wondering whether to descale or not.

        That said, I know from personal experience how much (ordinary) crap comes through from my home water tank.

        I have a large filter on the outlet line from the water pump at the tank,
        and then at the kitchen sink I have 2 charcoal filters down to 1 micron "absolute", and the UV light thingamie....

        This is what I put in the coffee machine & electric jug (and in my gut).

        When I change the filters (annually) it never fails to surprise how much green slime is caught up in the filter cartridges.... If you take a look on your roof....youll see what ends up in the tank.

        But by gee, the water tastes good...must be the flavour of all the contaminants. Come to think of it, the resulting coffee & tea taste good too!

        Regardz,

          I AGREE WITH PREVIOUS POSTONG, IF YOUR ELECTRIC JUG IS O.K. THEN IT IS MORE THAN LIKELY YOUR MACHINE WILL BE FINE

              Perhaps he was up on the roof checking his green stuff level and wanted to be sure and be heard. ;D :
