i guess there a number of variable involved. what temp is the water when you start, what type of elect. heating are you using, is the container the water in conductive of heat or insulated,etc... good luck

I Coulomb of electricity will decompose 18 g water (1gram equivalent). Therefore, 1liter (1000g) of water will need 1/18 x 1000 =55.56 Coulombs

for the reaction, its 2 electrons required per molecule of water. one kilo of water per liter. 55.55 moles of water per kilo. 111.11 moles of electrons per liter of water. 96500 Coulombs per mole of electrons. 10.72 million Coulombs per kilo of water.
multiply this by the voltage you wish to apply to power this process to obtain the energy required for the process, in Joules. its a hell of alot of energy.
