Reply to comment by bacon_cake in Is my power shower positioned too low on the wall? by sudzikle

No it's not, it's an electric shower unit that can only be used with high pressure water. There is no pump inside, just a constant rated water heater (normally 7.5 - 10.5kW) where the temperature is increased by slowing the water flow through the heater. That's why they normally need pressure at least 1 bar which normally means mains water pressure or a tank 10m above.

Most people here get mixed up between plain electric showers (which this is) and actual power showers (which have pumps / mixers / controllers hidden away and therefore no visible equipment on the wall except taps and shower head).

Oh I love the concept of being in a tiny wet room with a 10kW heating element.

They are quite common here and I never heard of anyone getting zapped.

Mine is 10.5kW and on its own wiring run with a dedicated 45A breaker. A pumped power shower would still likely have an electric pump on a 30A breaker if it's on the wiring ring used for regular sockets. Both types must be used with an RCD. I think in both cases we're a damaged seal away from potentially similar dangers.

So basically, a point of use water heater?

Yeah that's it, basically the same concept. Actually a lot of the smaller wall mounted ones look just like those showers but with a metal spout and obviously lower flow rate. I don't think the water heaters are that popular here, but the showers are.
