Chris Wilson Posted June 10, 2009 Share Posted June 10, 2009 The shower has packed up, it's an old Triton T200RE, with the heater bit remote, in the loft, and just a control panel in the shower. i can make a brushed stainless panel to mount a different sized control panel in the shower, to save re tiling, but it seems modern showers are 8Kw plus current draw. I draw (pardon the pun...) the line at re wiring the damned thing, can you buy 6Kw digital showers still, or leave part of the heater module disconnected to limit current draw? Thanks.

Todd Posted June 10, 2009 Share Posted June 10, 2009 You not just get a 7.5? Plenty of them on the market Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted June 10, 2009 Share Posted June 10, 2009 Aqualisa Quartz electric 8.5kw showers can run from a 6mm supply cable, which is *probably* what you have. Quote Link to comment Share on other sites More sharing options...
Dave17 Posted June 10, 2009 Share Posted June 10, 2009 Our old 6kw shower packed up in august last year, i just ripped it out and replaced it with an 8kw job, was assured that there would be no issues going up 2 kw, its still running fine...

It depends on the model of shower, and the size of the supply cable. Some are fine, others will not be. (IE some of the higher specc'd Mira showers have a huge draw) Quote Link to comment Share on other sites More sharing options...
supra matt Posted June 10, 2009 Share Posted June 10, 2009 What size is the cable 6 or 10 mm? if its 10mm then you have no worrys with the 8kw Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted June 10, 2009 Author Share Posted June 10, 2009 6 mm T&E off a 32 amp trip. Will a 40 amp trip fit in the same MK consumer unit rail? It doesn't look THAT bad a job to replace the cable, but if a 7.5 Kw digital shower (remote water heating unit) will run on the 6 mm cable I'll probably go for that. What's with these monster current draw showers, I thought we were supposed to saving energy? Thanks for the replies. Quote Link to comment Share on other sites More sharing options...

What's with these monster current draw showers, I thought we were supposed to saving energy? Thanks for the replies. The point of 10.5 kw and upward showers are to allow increased water flow through the showerhead without loss of temperature,everybody wants more whether it's kw or bhp it seems.The max for 6.00mm cable is the 8.5kw though this can be dependant on cable length and if its in a very enclosed area or through insulation,then you have no choice but to fit 10.00mm. If your mk board is fairly recent then the upgraded breaker should fit.I would advise getting a combined rcd/mcb unit. Quote Link to comment Share on other sites More sharing options...
edge Posted June 11, 2009 Share Posted June 11, 2009 Hi chris, I work for triton as an engineer and you will find its probably a 7, 7.5, 8 or 8.5kw unit. Most of the parts for these are now obsolete but can still source heater cans. The closest replacement for the old 200re's are the T300si's. They start from 8.5 and go upto 10.5. They now also make wireless units the same T300si wireless that has no cable between control panel and "box in the loft" http://www.tritonshowers.co.uk/digital-showers/t300si-wireless.aspx They are good units and have been about for 10 years roughly with the introduction of the wireless system introduced in the last couple of years. As mentioned above if you have a fairly short run of 6mm cable you can sometimes get away with 9.5kw but if you dont want to do the maths then play it safe with a 8.5kw.

CarlM Posted June 11, 2009 Share Posted June 11, 2009 10mm Twin & Earth = 53A, Max Load = 12.72kw 6mm Twin & Earth = 40A, Max Load = 9.6kw So the 6mm you've got for the supply will be adequate for the 7.5kw shower Although 7.5kw will require 32.6A so you might have to change your MCB.

snake Posted June 11, 2009 Share Posted June 11, 2009 Does it depend on how long the 6mm cable is from the fuse box to the shower, how big a kw shower you can use. Quote Link to comment Share on other sites More sharing options...
edge Posted June 12, 2009 Share Posted June 12, 2009 Does it depend on how long the 6mm cable is from the fuse box to the shower, how big a kw shower you can use. In most average size houses you dont have to worry so much but yes it does matter about length Its also depends where the cable is run aswel as heat factors have to be taken into consideration etc Quote Link to comment Share on other sites More sharing options...
Guest Link Posted February 7, 2011 Share Posted February 7, 2011 Not long ago I bought a 9.5kw electric showerfrom Gainsborough. Hope that it will be good. Has anybody used it before? Quote Link to comment Share on other sites More sharing options...

Odd first post on a Supra forum, but welcome. The more important question is, after nearly 2 years has Chris gotten around to fitting a new shower yet?

JustGav Posted February 7, 2011 Share Posted February 7, 2011 40A at 240v.... wow and that runs through something into a puddle of water *BOOM* My mig welder doesn't even draw that much..... Quote Link to comment Share on other sites More sharing options...
ozz Posted February 7, 2011 Share Posted February 7, 2011 I was looking at replacement showers and from the people I talked to gainsborough are the budget end (i'm replacing my gainsborough). Ours is a 8k and terrible, but with 9.5kw you should be okay. I just googled the models i was interested in for feedback. Quote Link to comment Share on other sites More sharing options...

Ours is a 8k and terrible, but with 9.5kw you should be okay. I just googled the models i was interested in for feedback. Gainsborough are going. Think Aqualisa are taking them over as the official giansborough sales are in the hundreds compared to ours that are in the millions. I would offer to get you discount but i can buy cheaper online or in a shop even with employee discount If you look at tritons go for a T80z. As a triton engineer it's the electric shower we see the least of and has a swivel water inlet to help with the pipe work but the cable entry is on the left on that but plenty of room to run the cable over. The 9.5kw is the ideal power as anything more you need larger cable and bigger fuse. 9.5kw you will want a 45 amp fuse although it may work through an 40amp trip depending how sensitive it is as with 9500 watts you are pulling 41.3amps at a nom 230volts. If anyone does have a triton that's in guarantee i may be able to send you spares free of charge. I'm not trying to big our company up (alot of issues at the minute regards work/pay) but to help out members as i work on these all day every day and look at about 2000 units a year Quote Link to comment Share on other sites More sharing options...
ozz Posted February 7, 2011 Share Posted February 7, 2011 Good offer Edge, I'm looking at Triton or Mira as favourite - we have 10mm cable already which helps. My dad (electrician/plumber) loves triton but recommends the mira sport. Quote Link to comment Share on other sites More sharing options...
ozz Posted February 17, 2011 Share Posted February 17, 2011 Just wanted to say thanks for advice Edge - bought a Triton T80z on monday, turned up today £91 delivered - cheaper than with my dad's discount at plumbcentre! I'll prob fit this weekend. Quote Link to comment Share on other sites More sharing options...
