Paul, take a look at the ScrewFix site. They are selling a powershower pump + thermostatic control rail, all hoses and the head for less than £200, sp. offer. It needs a hot water feed but as Dave says, far superior than an element heated one. I had one of these in the UK and really miss it! That's if your friend would like to upgrade, of course- depends on the cost of spares or a new Triton unit.
