Personally I think local instantaneous heating not only saves electrickery=

as a sport) and where constant high usage hot water is required.

Reasons for assertion:

Only heating the water that you actually use - so as kW's are charged in=20

a large tank. =20

Less than 500ml (3/4 pint) of water is 'wasted' between being cold and hot.=

Sadly they don't seem to be legal in OZ, especially now that it is mandated=
