One thing that really, annoys me is when a tradesmen comes out and just says “your electric shower has stopped working, no problem we’ll have that replaced in no time”. They might as well say “we’ll see you next year”, as walk out the door! A good tradesmen knows electric showers are particularly susceptible to limescale and he will inform customers about the choices they have! Why do electric showers stop working so often? It’s all down to the calcium in the hard water. This will deposit readily onto hot surfaces, and the hotter the surface the more readily they deposit. As the shower starts to scale up they slowly become more and more inefficient, it takes longer for the heat to get through the limescale. After a while they over heat, and a repair/replacement is needed.
Some Aquabion customers report that they have to turn the temperature down of their showers, because their water is now so much hotter. This is simply because the limescale layer (which insulates) has now been removed. It is this insultive effect of the limescale that will eventually destroy the shower, if there is no adequate protection.
So the next time you say “why has my electric shower has stopped working again?” you know where to turn to.
