How can you say this Davy jones !
I think electric showers are fantastic. Very energy efficient, you only heat up the water you actually use.
And the best bit, the water temperature doesn't change during the shower, you can have a 30 minute shower if you want.
And you don't have to wait for a cylinder of water to get hot.
And you don't have to beat your brother up because he used all the hot water 10 minutes before your shower.
OK, if you like a power shower, you wont be happy with an electric shower, but a power shower might get cold half way during the shower, just as you are rinceing the shampoo from your head, how miserable
