Dolphin shower installed in 2000.

A photo from a plumber of a twenty one year old Dolphin shower he is replacing, he wants to know what the black wire is for. 

My first thought was it's for a waste pump, but he cannot see one and a watering can full of water ran away down the waste. 

There's no sign of an extractor fan either, so I said terminated it and leave it in the enclosure. 

Anyone aware of something we have missed?

    @mapj1 is on the same wave length, I trained as an electrician around the time this shower was installed twenty one years ago and have never actually installed one of these myself as they were becoming obsolete at that time.

     

    I think it is an uninsulated water heater, but presumably it has been okay for over twenty years and has not killed anyone.

     

    Apparently this is the only circuit and appliance in the house that is not RCD protected and is supplied from a one way fuse board next to the consumer unit.
