Replacing shower

What Kw is this shower, and can I replace it with say a 7.5 Kw upwards with the existing electrical wiring and fuses?
Asked 9 years ago by Anonymous

This is an 8.5kw shower, and as long as the wiring etc is suitable anything up to an 9.5kw should be ok.

Fitting a more powerful shower to the existing wiring.

If your existing shower was installed with 6mm wiring (as it should have been) then fitting another shower (even up to one of the 10kw units) to the existing wiring should be no problem, depending on the length of the run off cable and how the cable is installed.

Here is a table that allows you to work out what you can do with the existing wiring, make sure you fill it in accurately as this can make a large difference to the eventual calculation.

You may also have to change the fuse

Up to 8.5kw  35 Amp fuse

Up to 9.5kw  40 Amp Fuse

Up to 10.5kw 45 Amp Fuse

If you are even in the slightest unsure about any of the above then please contact an electrician.
