It's flowing water, not a kettle. So the input power can only heat it so much. Power in = mass-flow-rate * specific heat * temperature difference So, temperature difference = 300W / (1.73 g/s * 4.2 J/K g) = 41 K If the input temperature is 20C, then the maximum output is 61C. If you accept the numbers as given. It's not like a kettle. The reason the graph shows a gradual increase in the temperature when the power is first applied, is that the reactor has to heat up first, and that absorbs some of the power. When it reaches equilibrium temperature, all the power goes in to heating the water.
