I think you meant NOT believe or at least have a question mark at the end. Either way, I did not know that his water flow is not metered and would agree that that is a problem. A big one.
I don't think this is a problem. Again, the input water jug was open for all to see, and a 7 L/hour fall in the level would be easy to verify, either by marking or weighing.
Here is a video of the calculations:

What's interesting is, that the input is computed to be ~770 wh/h, and the output is
4300 wh/h from vaporization
600 wh/h from heating up 7L/hr water from 25 to 100 degrees C.
If the output water were to be at 100 C with NO steam, then there would be no net generation of energy, whereas if the water coming out were completely vaporized, the output is 4300 + 600 = 4900 wh/h, or 4900/770 = 6.36 mor than input.
For this reason, the assumption regarding what percent of the output water was turned to steam is critical. When Rossi pulled out the hose, no significant amount of water came out, but I suppose a skeptic might say that he shook out the condensed water, etc.
But even if half of the water input were converted to steam, the output would be 2150+600 = 2750 wh/h, or 2750/770 = 3.6 times the input value.
Calcs from the video:
--------------------------------
615.6 watt_hour per kg
615.6 * 7 = 4309.2 watt_hours/hour
100.1 - 25.3 = 74.8 kcal/hour
specific heat of water = 1
1 kcal = 1.14 watt_hour
85.2 watt hour x 7 = 596.9 watt hours.
4309.2 + 596.9 = 4906.1 = produced
3.5 amperes x 220 V = 770 (if 200 V) or 805 (if 230 V) wh/h
4906.1/770 = 6.37
I suppose an easy test would be to increase the pumping rate from 7 kg/hr to 56 kg/hr (or about 1L/min). Not sure that the resistances would allow this. Then if the ecat were producing the same amount of energy, it should take a input water flow at 56 kg/hr and put it out at close to 100 degrees celsius (8 x 615.6 = 4924.8 wh/h). And then the steam issue would go away. I do believe that some of the earlier tests were done with a water flow that did not reach vaporization energies. I also suspect that running too much water through the cooling jacket might lower the temperature in the reactor vessel to below the optimum level. For this reason, it may not be trivial to change the experiment in this fashion.
