This graph assumes the fluid is at the temperature indicate by the x axis already before adding the additional heat. So in the process you must include the energy needed to get to that temperature.
Also, 650 K is 377C or 710F; way higher than 210F for sea level boiling.
There are no free lunches in physics.
I have a BS in chemistry. This is first semester chemistry stuff. It’s not even college chemistry. Water evaporates, even ocean water.
Why don’t you answer my question instead of posting a phase diagram that you obviously don’t even understand?
