There is a reason why you can't drink water in the shower.
Also, is incredibly inefficient because you lose a lot of heat in the pipes from your tank to your shower and a water tank + pipes cost hundreds of times more than what an electric shower head cost.
The British also realize it, but are still afraid to mount the resistance directly at the end of the water to maximize efficiency.
