99% conduction from the element in the water. 1% convection from the small vapor bubbles emitted at the surface of the element from surface irregularities not heating the water uniformly and the growth of some small vapor bubbles at the element.
Convection transfers heat at 1/100 th the effciency of the direct conduction route. (Think of it like this...blow some 50 degree air across your skin versus throwing a glass of 50 degree water across the same skin. Water cooling -conduction- is immediate and intense. Convection of 50 degree air across skin is not uncomfortable at all|||Electrical energy heats the wire.
Conduction and film boiling (convection) occurs, vaporizing the water.|||Well!!!
Conduction as well as convection
