    Last few batches I've made with water direct from my solar hot water because it comes out at around 65 so I use less gas to heat to mash temp. I've just suddenly thought to myself, is this a good idea?

    A quick Google produces information that hot water heaters produce nitrate which is linked to oxidation and stomach cancer. Also metcury, lead, all the good stuff. Great.. just mashing my latest pilsner in it..

    I do have an esky to catch the overflow relief valve when it gets too hot and the sides are stained a light blue from the water. It used to run into our new tiles and they're stained white

    What are your thoughts on this?

    Don't eat spinach when drinking the beer, you'll be OK.

    Hot water nitrate levels are in the ug / l range (parts per billion) where spinach can have nitrate at 3 g / kg.

    1 gram of spinach can contain as much nitrate as 1000 litres of hot water.

    I stopped using hot water after reading about issues due to old pipes (lead in the solder, hot water causes it to leach out faster than cold water) so I only use cold water now. I think it depends on both the equipment your using, and the piping. One day, I'd like to have the right kit to make that work.

    Sorry for dragging this OT.

    So these results are saying I need to eat more spinach to help control my high Blood Pressure, cholesterol and low iron levels?

    I used it when I lived on Bribie Island. Made perfectly ok beer. Some award winning actually. As for heavy metals etc I probably picked up masses of them in my decades before catalytic converters, unleaded petrol etc.

    Sacrificial Anode Pilsner.

    Sounds bad but probably harmless, I mean the HWS water should be fit for human consumption, shouldn't it? Then again, I'm no doctor either...

    We drink, shower and live on rain water. Have a hot-water system too.
    Could be bird, possum, frog and who knows what poo in there.
