I don't know about a hole in the device other than the one the hose is connected to, but the reason steam vents to the room is because the pressure in the device is higher than in the room. A ball rolls downhill, and fluid flows down pressure. Of course gravity affects fluid flow too, but the ecat has to push the fluid up first, meaning still higher pressure is needed. > Therefore, the pressure should be 'near' room > pressure. Near, maybe, but higher, definitely. It doesn't need to be very much higher to increase the boiling point a little. It only takes 30 cm of water depth to increase the bp by one degree C. > So perhaps the disagreement on pressure is simply a > communication issue. If Rossi uses a slightly elevated bp as evidence of dry steam, then the issue is more than communication. The fact that the temperature is perfectly flat indicates the steam is at, not above, the boiling point.
