Thinking of optimizing consumer properties of electric water heaters I found some gas hybrid heaters, but no electric.
The Rinnai RH180 http://www.rinnai.us/hybrid-tank-tankless-water-heater/how-it-works
And more interesting Grand Hall's Eternal Hybrid - which uses infrared heating and mixing electric valves

The problem of the common tank electric heaters that water cools down when tank is near to empty: spiral heat all new coming water and usually too weak to heat it all quickly, besides spiral most probably is turning on after some hot water gone from the tank.
The tankless heaters usually can provide only limited flow of water.
My offer is to combine two chambers with electric valves
Controller may actively direct the supply of hot water. From start from heater + tank, when tank is empty there could be some alarm and flow reduction to usual thankless mode (less hot water, but predictable constant proportion. When tap is closed it full in the tank... To keep it hot the extra loop to heater chamber could be added.
Even more add cold water mixture under computer control and precise temperature will be in outflow (the flow - not temperature will decrease when tank is empty).
Instead of traditional electric spiral heating element (which rust and decrease efficiency) the modified magnetron could be used (like in microwave oven).
