Looking to replace an electric shower with a 12kw multi-flow instantaneous water heater from Heatstore. I've removed the old electric shower and all the wiring (cable far too small - needs 10mm2) and MCB from the consumer unit and was looking to procure all the parts required for the Heatstore.
The consumer unit I have is a MEM unit from the 80s and seems to only accept MCBs with a max rating of 45Amps (if I were to buy a second hand one from ebay as you cant get new ones to fit).
So I figure that the best thing to do would be to install one of these separate shower consumer units with built in RCD and a MCB rated to 50Amp (as per the MCB rating specified in the Heatstore installation manual). All of the 50Amp MCBs seem to be rated to 11Kw (MK units) or 11.5Kw (Wylex Units) max rating though, and I need 12kw.
Can anyone recommend a good brand of unit that will suit? or will this make much difference?
There is a crabtree unit in screwfix (starbreaker shower kit) but the spec they give you on their website is pretty basic and crabtrees own website is dung also. Looks not too bad for £41?
