Never heard of a shower like that. Here's a little tip that I have learned
about showers, chose a make of a manufacturer that has their own service
organisation because when it goes wrong (they all will) you will be able to
get it repaired. Triton service is good. Most plumbers and most electricians
can't fix showers.
You could fit a conventional shower and an immersion heater for use when the
fires out or at the end of the day.
