Telling us the answer would enable us to tell you what Kwatt shower you can fit.What amperage is the MCB ,or fuse that protects the shower circuit ?
As has been said, it doesn't really matter what is the power rating of your present shower - as has been said, if you tell us the rating of the MCB supplying the shower (and, ideally, also the cable size if you knew it - but hopefully that will be consistent with the MCB rating) we can then tell you what power of replacement shower you would be able to install.Thanks for your help. All I know it is a Triton Opal Chrome, but unsure of the model or KW. It meant to be underneath but it isnt and on the inside, which clearly it isnt either. So bit stuck, as need to replace it because of a fault with it leaking from the stabiliser valve I think.
If, as seems to be the case, it is the OP's wish/intention to replace the shower, rather than attempt to replace it then, as I've written the power of the current one is irrelevant.You could measure the resistance of the shower and calculate the power rating.
Providing the resistive parts haven’t failedYou could measure the resistance of the shower and calculate the power rating.
