Get used to it.
To say this you need to know exactly how much water E-Cat can contain in liquid form. If you cannot answer that then your argument does not have any relevance, because you lack crucial details of the experiment. You can make tea pots with water pump, but you need to know what is the volume of the teapot. So what is the exact volume of E-Cat? It is important that tea pot does not overflow, because it messes up calculations, because steam is not dry anymore. Therefore E-Cat's inner volume has to be big enough to account power fluctuations because peak power can surge over 120 kW. On the other hand if all the water boils away, core temperature may rise too high.
