Assume a large metal tank of water is placed on top of a house to
provide hot water for the kithen sink and the bathroom sink and tub. 

Assume sundown is at 6.  What color should the tank be?

AIUI, white will not absord the heat as well, but it will keep the heat
it does absorb longer, so there will be hot water until 7,8,9 PM

But black will absorb the heat faster, will be able to absorb more heat
on grey days, and will have hot water ready by noon instead of 2PM.
However it will cool off sooner and the tank will be losing heat even
maybe before sundown and very likely the water will be almost cold by 7.


Which of my statements, clauses, adjectives, are incorrect?

What color should the tank be for best hot water?   The most hot water? 


Ignore the possibility of sometimes using a supplemental electric
heater, except that the solar heater is to be designed to make that as
little necessary as possible..
