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.

Maybe the Scots like to save money.

Don't believe that.

You don't believe the Scots are skinflints? We're famous for it.

That was a joke, Joyce.

There's a saying that goes something like a Scotsman is in practise to
become a Jew.

By hacking the end off their dick with a claymore eh ? Yeah, right.

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

Trivial to insulate fully.

No insulation is anywhere near perfect.

Doesn't need to be.

Does, or the boiler keeps coming on when you're not having a shower.

Only a fool uses a boiler to heat the water in a storage hot water cylinder.

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
:-(
