The output check valve operates by opening further as the pressure increases across it. It will not open any additional amount unless there is a finite pressure applied. There are several reasons for the ECAT internal pressure to rise. First the temperature of the water within the ECAT can increase. The temperature and pressure are connected by the saturation tables. The second effect is more subtle and is seen by the slight rise is T2 that is detected near the end of the run. This also will cause the pressure to rise and I suspect is because we are starting to force liquid water through the output valve along with the vapor. The water clogs up the valve and restricts vapor flow.
The pressure at the input end of the heat exchanger will be slightly above atmospheric due to the fact that this specific pressure must push the water from the exchanger toward the sink. The magnitude of the input pressure increase will be proportional to the amount of water forced through the heat exchanger and pipes, etc. The effect is similar to the voltage drop that occurs due to current flow through a resistive element. The value of the internal pressure of the ECAT will have to compensate upward as this pressure on the far side of the valve increases. All of the above effects are present within the ECAT device and contribute to the temperature reading at T2. A wealth of data is hidden within this function, T2 versus Time, that I have mined on several occasions. More ECAT operational details are still visibly acting upon T2 and remain for someone to decode.

The pressure did not change, so the steam temperature did not change. When heat increased, more steam was generated, but the temperature of that steam did not rise. When more steam entered the heat exchanger, the temperature of the cooling water rose. - Jed
