To conventionally explain the boilingpoint of 100.5 degrC the backpressure in the Ecat must have been 30mbar (for a boilingpoint of 99.6degC) and 20mbar for a boilingpoint of 99.9degC. This compares to resp 30.6 cm and 20.4cm water and this is about the hight of the chimney. The difference in temperature of the steam can ofcourse only be explained if the chimney of the ecat is almost completely filled with water. This is ofcourse the big question.
That's brilliant, actually. Add to this head of water, a little bit of steam back-pressure, it's quite easy. In other words, if the E-cat is filling with water, to overflowing, we would expect the temperature, when the thing starts to boil, to exceed 100 degrees, even if there is flowing water, and, in fact, *especially* if there is overflowing water, the chimney is full to the level of the hose. Exact placment of the thermometer may be important.
