from what I understand this is on the same principle as the small water tank heater like you have under a sink
you have a pot of hot water, that pot is constantly cooling down and you need to keep reheating it, which wastes a lot of energy
it's better than microwave, which mostly heats up the magnetron

1kWh of electricity will give you 1kWh of heat
problem is, that heat is not being perfectly delivered to the water you want to boil, but rather the device itself, then the room and then it leaves through the windows
The most efficient is one of these, you only heat the water flowing through the pipe and nothing else.
there are fancy taps that have a button to dispense boiling hot water
