When I was an apprentice we used to boil a cup of tea by placing two metal
plates in either side of a large pint mug and connecting the plates to the
mains. It works but don't try this at home children cos if you plug in too
many it blows the mains fuse. :-).

eeeek! That can't be right, can it? It sounds as if you're saying the
live element is immersed in the water?

What do you think would be the problem?

Some heaters (not showers) work by passing electricity through the
liquid to be heated.
