    Yes but hot water continues to flow in.

    And it doesn’t need to stay very hot. It just needs to be warmer than the outside air temperature in order for vapor to form.

    The ground and continuous hot water input keeps everything insulated.

      But cold water is also continuously flowing in. And as someone said, it perhaps cools down quickly. Is that all and all enough for such a dense vapor cloud to appear as in pic?
