Accordingly, what makes a powerful electric shower?

Electric showers are rated in terms of kW, generally coming in between 7kW and 10.5kW. Power is important because the more a shower has at its disposal, the more water can be heated and passed through at a time, resulting in a stronger, more consistent flow.

Subsequently, question is, is a higher kW shower better? Most people associate a higher kW rate with a better shower. The higher power means a consistently greater flow of water at your selected temperature which can give a real luxury experience.

In this regard, which is better Mira or Triton showers?

Mira Electric Showers: In the case of Mira Showers, it isn't as popular as the Triton because it is more expensive, but this electric shower is still more powerful and has a more modern look than the Triton. The showerhead in Mira Showers is larger than a lot of electric shower brands and it has four flow settings.

What is the difference between a 9.5 kw shower and a 10.5 KW shower?

8.5kW, 9.5kW and 10.5kW all exist because of another important aspect of showers, pressure. Higher powered electric showers have been introduced to combat this issue, so a higher power 10.5kW shower will be able to run at higher pressure at higher temperatures than 8.5kW electric showers.

9.5kW is either 39A or 41A depending on the voltage it is rated at. 6mm cable is 47A when installed in the most favourable conditions. So 6mm could be used, depending on how it is installed. However it would be usual to use 10mm which would allow the fitting of a higher rated shower either now or in the future.

The 9.5kW shower draws 41A if you use 230v, but as most supplies are 240v it will draw below 40A. I would go with the 9.5 kW shower, the cable will not be loaded for long periods and it is not a long run. If you are concerned, check the VD with a meter when the shower is running.
