I'm thinking about an ensuite for the attic room. Problem is the header tank for the water system is only about 6 ft above the floor level there. I have easy access to hot and cold fed from the tank and mains cold too. So of course an electric shower could be an answer. Trouble is the cable run for that would involve a lot of re-decoration elsewhere. Any thoughts?
I did think about it since I changed the boiler recently but the mains supply here is low pressure and poor flow. And the header tank system works just fine.
Could you run the cable for an electric shower externally. Although I would never allow such a thing at my house. or Get a new water supply. There are standards for the pressure and flow in the street main pipes AFAIK so it is probably your supply pipe that is old/shared with next doors/scaled up that causes the poor pressure and flow in your house.

Don't they? Instant electric heaters involve water passing over the uninsulated heating element. Electrode boilers (seen in industry) involve the electricity passing through the water. All safe enough if installed properly.
A shower pump consists of an electric motor, bolted on to the output shafts on either side of which are pumps. The chances of water and electricity coming into contact in a shower pump, no matter how badly installed, are as close to zero as makes no difference.
shows one and the enlarged image shows how difficult it would be to mix water and electricity in one.
I have seen shower pump installations with an RCD. Whoever installed them was either talking the job up if a "professional" or not very good at assessing risk if an "amateur".
