    Put it in jerry cans and leave it in the car park of your apartment complex. When you have enough full jerry cans empty them into your washing machine.

    • Wonder if any jerry cans go missing.

    • Only useful for laundering wetsuits

    Ive got a 10m^3 hot water bottle water storage tank built under my front garden. Put it in there and get it pumped twice a year.

    I give mine to children in Africa as clean, boiled drinking water.

    • Everything's relative I guess.

  • Empty it into washing machine or put it in a bucket and save for watering plants/washing

        Hotels in Amsterdam (travel advice) vs 'Water bottle contents' is the DUMBEST comparison ever.

          well i was concerned that there could be a health issue drinking or reusing the water, as a homeowner i pay for water, so i'm always looking to save a few extra bucks here and there.

          travel advice, maybe a travel forum like tripadvisor. just saying.

          just because something isn't important to you doesn't mean it's not important to someone else……………….

          how would you feel if i posted dumbest thread ever on one of your posts?

          maybe next time you'll be a little more considerate to other forums users before making such targeted comments.

        • @myusername:

          I'm sorry but if you are contemplating drinking that water then I'm not sure how else I could frame it. The 'funny' responses on here should give you some indication of what others think about the question - perhaps not as blunt as I am .

          Great to see you want to save water BUT the amount you're potentially saving is less than $1/year. I'm sure you are wasting a lot more by turning the tap on/off 2ms slower than your max potential.

          You can always use a wheat bag and save a lot more on water and power.

    Tip it down the drain

    Use it as the flush for your first wee of the day.

      And when the toilet is cleaned and bottle is empty… guess you can wee into the bottle and snuggle with its warmness.

      • +1

        Then you can use that to flush your next wee…

        wait!

    I had a good chuckle in this thread.

    Pour it on windscreen in the morning to defrost before you drive.

  • Use it to wash my car

  • If you get yourself a spare dedicated kettle, you can reboil the water

      Did some rough calculations
      Price of water $2.6097 per kilolitre
      Volume of hot water bottle 1/3 of a litre
      Price of kettle $10
      Used once a day, every day of the year

      It will take approximately 11495 days, a bit over 31 years, to pay off the price of a kettle in water savings

      • assumes the kettle will last 31 years
      • Also assuming you pay for water.

      • The maths can change a bit if,

        You use 1 litre instead of a 1/3. I use closer to one litre right now.

        Price of water has gone up in the past, no reason to assume it would do anything but.

        And you could pick up a gumtree kettle for less I reckon.

        Could change the maths to around 5 years.

          Now we need a physicist to tell us how many times you can reboil 1 litre before its all lost to evaporation

    Refill my Bong.

  • Reheat it and put back into hot water bottle.

    Pour it down the sink, lol
    2L * 100 = 200L
    This equates to something like $0.50/year (assuming 100 days of use a year).

    If you're that worried about water usage, install a rainwater tank…

      I do it because I worry about waste wastage. I erk at all waste in general. In vic, we paid some stupid billions of dollars to build a thing to create clean water, and we waste a lot down our toilet. So I find other water sources to put down mine.

      My place doesn't have enough space for rain water tank, or else I would install one too.

  • top up fish tank

    • will it harm the fishies?
