ELI5: why are water boilers much faster at boiling water than a pot on the stove?
gpt
The heating element is in  much better contact with the water than in a pot on the stove.  The pot sits on a rack suspended above a burner, or touching part of the heating coil.  That's much less efficient than having the water directly in contact with the source of heat.
