A few places have this at £49 at the moment, although there is a voucher code for an Extra 15% off - MAY17
Not the most powerful, but it's a good price for this model and reviews look pretty good as well. If you're not looking to spend a fortune, then it's worth considering.
Info This Triton Riba is perfect for a quick and easy replacement of an existing electric shower. The multiple cable and pipe entry points ensures this can be installed with ease. Extremely easy to operate with a simple start, stop, control and temperature control with an optional power setting feature provides efficiency and is eco-friendly.
Well said "othen". You can't just say 6mm cable can take 47 amps and is fine for an 8.5 kW shower. There are more factors to take into account such as where and how the cable is routed to the shower unit. Seek advice before you burn your house down or kill yourself! There is also no way this would work on a lighting circuit and I'm sure it was a joke!

The current carrying capacity of 6mm^2 is 39A (see Table 4F1A), which means a B32 MCB, which would not be sufficient for a 8.5kW appliance (37A) - that is the regulation, but saying that would a 6mm cable and a 32A MCB work? Almost certainly, but the main factors would probably be a. Voltage drop (lower potential difference at the shower means higher current in the wire, and hence a bigger heating effect) b. Thermal insulation (the figures in the book are for direct clipped cable in air - if it is running through 10m of insulation the situation will be very different).
I'd rather that electric showers were not available to the public at all because they look so easy to fit or change, and most DiYers have no idea about voltage drop/current carrying capacity/over current protection/fault protection - and as a consequence I see a shocker (sorry for the pun) every now and then. The biggest danger is where someone fits a more powerful (particularly 10.5 kW - drawing 46A, or more if there is significant voltage drop) to replace a 7kW appliance connected to a 6mm^2 cable (I've even seen 4mm^2 cable). Sometimes the MCB has been changed for a larger one because it kept tripping (for what reason I wonder?) without the DiYer realising the cable then had no over current protection. I know it always says on the packet that the shower should be fitted by an electrician, and that new installations are notifiable, but that does not stop people doing the above to save a hundred pounds or so (and risking a fire).

Yeah definitely not safe, standard lighting cable normally 1.5mm cores and main supply cable 2.5mm cores. Hope just a joke if not I'd suggest taking it out now.

i moved house last year where i had a mixer shower and the new house had an electric shower which was 8.5kw. initially i hatred the electric shower since the flow rate was so bad. i contacted several plumbers and got quotes to install a mixer shower. i then watched a YouTube video where someone suggested changing the shower head. i had the Mira mixer head from the old place so i switched it and ever since the flow rate it's been amazing. my wife complained she couldn't wash her hair properly with the cheap head that comes with these electric showers but now she loves it. try changing the head before anything else.

Cold 8.5kw is not enough to give a decent flow rate of warm water in the cold winter. I would get 10.5kw min

Seems cheap, though we've had issues with triton.

Installed extremely easy and wired up to my existing lights.

Not sure if you are being serious or not ? But chances are the cables supplying your lights are no way big enough to supply this safely.
