"Bought this to replace identical model which had failed after 3 years. Good price for this product. easy to install. higher killowatt the better if you want to have a forcefull shower at a decent temperature. 8.5 killowatt is the minimum in my oppinion 9.5 and 10 killowatt are better. Bare in mind though you may need to upgrade the supply cable and RCD if you install this in place of a less powerfull shower. If you are unsure how to wire this product to current regulations then contact a qualified electrician or plumber to undertake the instalation for you! well assembled quality product from a reputable brand at a hard to beat price. This shower must be fitted to a mains water supply."
