Reading your comment about jug elements reminds me of those porcelain electric jugs with a bakelite lid and a bare coiled coil element on a china former hanging down inside the water that were very common in Australia when I was there some 20 years ago. I was amazed that a country so fussy about who could do electrical work would allow such a potentially lethal device. I saw one in use once with a broken lid such that it was possible to put your hand inside and touch the live water. Do you still see them there?
I brought one home as a souvenir (sad I know, my daughter brought home a cuddly toy platypus but then she's not an engineer), and also a spare element (still in its packaging) just in case.
