So how can a resistive element be more efficient than another resistive element when fed with the same amount of energy?

What may not be disclosed here, is that an intelligent device is connected to the geyser, which then uses an algorithm to calculate when power is applied to the element. This then will give you the types of electrical savings as claimed, but simply changing an element of the same value to another of the same value WILL NOT SAVE YOU ENERGY. Adding a geyser blanket and cladding pipe work is another means of reducing standing losses.

I think that the whole story is not being published.
Unless current geyser element are really very inefficient, and this version has improved on the design?
