I have a 9.5kW Triton shower connected to a dedicated CU (50 amp MCB and RCD) with 10 mm twin and earth via a 50 amp isolating switch. The flow was pretty reasonable in the warmer months, but now that water temperatures have dropped, the flow is not as good as I was hoping. Hence, I'm thinking of getting a more powerful unit when time and money allow. 2 questions: Is my circuit adequate for the most powerful electric showers available, and what is the rating of the most powerful shower on the market?
