Remember that instant electric showers involve the water people

Nope. They're just glorified electric kettles.

Incorrect. Such heaters merit a special section of the Wiring
Regulations, at least they did in the 16th Edition. There are a
number of requirements to install them safely. I have no intention
of regurgitating them.

It is a good idea for you to get someone else to design and fit the
installation. That is the best advice you will receive here.

It's not rocket science though, is it? If you don't know,

I do know, so your point is moot.

The *rules* may be a little complex (and I admit to not
knowing them myself)

Ah.

I have explained why such heaters can be dangerous. Such heaters can
be safely installed by DIYers, but those who do not understand
earthing are best advised to practice their electrical skills on
other projects first. What is likely to be the highest rated
appliance in the house and one which involves standing naked,
perhaps in a metal bath, in a stream of water which has passed over
an uninsulated heating element, is not a good project to practice
on.

but I'm sure anyone with a bit more eloquence and
patience than you could explain them simply enough.

Excellent, a personal attack. Do keep it up.
