In this discussion, it took Hustedt a while to figure out that the condensed water from the primary loop is being flushed down the drain rather than recycled back into the cell. The original plan called for it to be recycled back into the cell. In his latest comment he notes correctly that heat lost with the warm condensate going down the drain from the primary loop would only add to the performance of the eCat. ". . . Excess heat wasted out of the condensate side will be additional heat output from the e cat not included above, ie it will only make the ecat look better when this is included."

"18:57 Measured outflow of primary circuit in heat exchanger, supposedly condensed steam, to be 328 g in 360 seconds, giving a flow of 0.91 g/s. Temperature 23.8 °C."
There is a serious problem with the output temperature recorded for manual measurement of the "condensed steam". It was repeated. Perhaps that was a repeated recording error. The "condensed steam" is measured leaving the heat exchanger at a temperature lower than room temperature by at least 5°C, and lower than the Tin of the exchanger by 1°C. This is not possible. However, if even close to true, the efficiency of the heat exchanger is very high. Since it is a commercially built model that can be expected.
