But if you don't even know the relationship between volts, amps and kW then no way should you be installing a shower yourself - you should get an electrician.
It might, but probably won't.
Almost certainly the cable won't.
And it does all need uprating, as 7.2kW will be a feeble shower.
Changing fuse/MCB ratings and installing new cables is also an electrician's job.
In England & Wales, all of this work is notifiable too....

You can have up to a 7 kW shower on that fuse. But what determines the max load is actually the cable. You probably have a cable rated for 30A at least. If your cable is big enough, you could have a bigger shower. You also have to take into consideration how the cable is routed to the shower.
As a guide, you could consider looking at 7kW showers, but you really need to have the circuit looked at by an electrcian to know how high you can go.

It will give a hot shower at a very pitiful flow rate.
This time of year, at a reasonable flow rate it'll give a tepid shower.
At no time of year will it ever give a hot shower at a good flow rate.
You need to be looking at around 10.5kW.

Which would mean upgrades to the cable and changes in the consumer unit.
thanks somthing i must do then (change the board) thanks anyway
but if your water supply is low pressure then 7kw will be fine. At my old house the water pressure was not the best but the 7 kw shower was to hot on full power!
However in my new house i have over 2 bar at the tap. Fitted a 10.5 kw shower and it could not heat the water fast enough. I ended up putting a good combi boiler in and using that instead. But this time of year i have to reduce the supply pressure to get the thing to heat fast enough.
