Replacing a Mira sport max 10.8kw with a 9.8kw

Hi, we currently have a mira sport max 10.8kw installed, but it keeps tripping the mains, it's the second one we've had in 6 years, so we're getting about 3 years out of them, which does not seem to be very much. I was wondering if from a plumbing point of view it would be easy to change to the 9.8kw one? They look similar from the outside and as I can't do it myself I need pretty much a like for like replacement, but I'm fed up with purchasing top of the range really expensive showers to only get 3 years out of them. Many thanks for your help, Fiona

The new Mira Sport is a direct replacement for the old, except for the bottom fixing hole.

As for the tripping of the mains,

it may be a faulty elementin the heating tank (there are two, three in most 10kw showers) you can checkthem with a multi meter you should have a reading of around 12>18 ohms.

If you have power to theelements and no heat it's probably the elements, no power to the elements thenit's probably a micro switch.

If you don’t have amultimeter we sell them at £10 each with a guide on how to use them forchecking and testing the various parts of your shower.

Apart from helping to fixyour shower, they are really useful for checking you have a power supply toappliances, for checking fuses, letting you know much power you have left inbatteries

(so you know if they are dud ornot) and lots of other jobs, in short they are well worth the £10.

These are cheaper to replace than a new shower.
