One for a qualified sparky / plumber I feel...
In the ground floor extension to the side of the family home, I have a shower room, it currently has an electric shower of sorts, it is one that just uses electrickery to push the water out with some urgency, doesn't heat the water, so is reliant on the tank in the upstairs airing cupboard / immersion heater.
It's not the best setup and is better than the non-electric predecessor shower, but it's getting noisy and I think it's the impeller that's going to fail.
Now the shower run's off a domestic cable and not whatever the big juicy cable is that you have to use on a proper power shower. My dad tells me there is no legal way to run such a cable from the fusebox to where the ground floor shower is.
I've drawn a really really crude sketch of the jist of the ground floor layout, is there a way of doing it that would comply with current regs?
