What Water Boy said abut the efficiency rating is extremely important. The boundaries of the system makes all the difference if you lose energy when you get outside the boundaries. Your "precise energy input calculation" is fine, but the key is in the efficiency and the definition of their efficiency rating. If they are only including it up to the heating coil, then they aren't telling the whole story.

I've been doing a little research this morning to confirm what he said, but haven't found anything yet.

I agree with your theory to certain extents...Now let's look at this backward then. You need certain heat energy to bring water from one temp to another temp. That is empirical per the heat specific coefficient 4.2 joule/gram of water per degree C, right? That is entirely accurate give or take for how much heat you need to boil the water. I do not think Wanderport contributes anything on that aspect.

Then our task is to transfer that whatever joules needed from the heat exchanger to the mass of flowing water. Also, another task is to convert electricity to heat at the heat exchanger. You see that it take a bit of transfer and conversion between electricity to actually raise water temperature. It is probably true that 99% watt gets convert into heat, but does all that heat goes to the flowing water....? How could we keep up with that heat transfer? This is a dynamic environment, not a static one like boiling water on a stove, so the heat transfer and heat exchanger play a big role on how to possibly boil flowing water.

And that is where the improvement is.
