No, we used to have those things in the UK. Then we got electric
showers
for more pressure.

I've never understood why people have electric showers if they have a
hot
water system at mains pressure

Me neither, abortion of a system, particularly now its so
cheap to insulate the tank so it doesn't lose much heat.

Because a lot of folk only switch on the tank when they know they're
going
to need it, which means planning your shower.

I don't believe that a lot are actually that stupid.

Most are like that in fact.

Don't believe it.

Probably because the tank doesn't stay hot and wastes fuel.

Trivial to insulate fully.

But with a combi boiler there's no reason for an electric shower.

(as opposed to a header tank in the loft).

Even then, that worked fine in the last flat I rented before I built
the house. And the flat was on the top floor with the tank in the
roof space just above the shower room/laundry. Worked fine.

Surely hot water at mains pressure heated in a tank or on demand in a
combi boiler is just the same pressure and possibly better flow rate
than
an electric shower which heats the same cold water as a combi but
electrically rather than by gas or oil.

Yep.

Our old house had a fantastic oil-fired combi boiler which could
supply
hot bath water for ages, and yet the shower was electric and had a
piddly
flow rate because the wiring to it was only rated for an 8 kW shower.
If
you turned the temp up a bit, you could see the flow rate reduce :-(
