Many, many years ago was there not a Tomorrow's World item on an electric
water heater in which it was implied (or maybe even stated) that the
electricity *did* go directly through the water?

That would be an electrode heater which are widely used for bulk water
heating in industry etc but not AFAIK used domestically.

Certainly not in the UK; but in Australia ....?

I recall my shock (=astonishment) on first encountering an electric kettle
in Australia, opening the lid on
the plastic kettle to fill it, I saw two plates separated by an inch (or so)
which formed the 'heater'!

The kettle worked .... (what more can one say?).


Wonder how the impurities in the water affected the "time to boil".....
