Replacing the heater in the ATLANTIC 50l boiler with a stronger one

Hello!
I need an advice. The heater in the Atlantic 50l boiler burned out (1600w heater). I found one that was used with the same mounting and the same thermostat, but with a power of 2000w, which was installed in a 10l boiler. And here arises my doubt as to whether this heater is a good choice. Will it burn out after a while. Will the assumption of a more powerful heater be more beneficial from the economic point of view? Since the heater will be stronger, the water will heat up faster, will I pay less for electricity or vice versa, the electricity consumption will be greater?

Photos of the heater that has burnt out and the rating plate on the boiler:




Pictures of the heater I am going to buy and the rating plate of the boiler from which the heater comes from.

Higher power of the heater = higher current, but the same amount of water heated faster. It will be similar for payment.

So I can easily set up this heater despite the fact that it previously operated on a smaller tank?

No problem if it physically fits

Thank you for your help. I am closing the thread.
