• Question: why does hot water from the tap have lots of tiny bubbles (which make the water cloudy until the bubbles have eventually disappeared) while cold water doesn't?

      Hmm interesting question… “Colder water enables more air to dissolve into it naturally. As water becomes warmer, less air can remain dissolved and it comes out of the water as tiny white bubbles”

      I should admit that isn’t my answer, I was interested so went off looking … http://www.anglianwater.co.uk/household/water-quality/facts/cloudy/

      From the link Rob put down, it might just be that the hot water doesn’t get used as often as the cold water, which means you get more cloudiness when you do use it. Oddly enough, in my house it’s the cold water that has the bubbles most, so it’s probably more to do with the particular arrangement of pipes in a place.

      It’s the hot water thats cloudy for me. I think it probably is a down to which water stays settled the most.
