Ta to all the repliers so far.
Regarding the Electric shower, I find the 10.8Kwatt one very commendable,
I'm worried about putting a second one in when the main consumer unit is
rated at 100A.
So, were I to go the "pumped" route, I wouldn't want it to be a fitted
just to mimic the flow I get on the downstairs gravity shower.
What kind of pump then? Where's the best place to buy it? What's all this
about "3 bar"
