I'm about to install a new shower. I've got an 80k btu Sime combi
boiler.

Can anyone recommend whether it's best to install a thermostatic
shower connected to the combi boiler, or an electric shower?

Has anyone got direct comparisons - e.g. is a thermostatic shower from
an 80k btu combi definitely more powerful than even a 10kw shower?

Any advice much appreciated.

Thanks
