The only advantage that I can see with a smaller kettle is that it may be easier to boil a small amount of water than in a bigger kettle. If one were to put a single cup of water into a big kettle it would probably barely cover the bottom (which probably wouldn't be too good for the element), but the same volume of water might be quite OK in a

Answer. For your parameters (except we will use their 151 liter number) the answer would be: (4186 J/kg°C) (145 kg) (60 °C - 8 °C) = 31.6 million Joules 31.6 million Joules / 3.6 million Joules = 8.8 KW 8.8 KW X .15 = $1.32 The rating of the element in your water heater has nothing to do with the cost.
