This idea was mentioned in another thread. In principle, if one put an
electric shower on the oputput of a combi, you'd egt even more heat
input to the water, and thus get even more flow rate to give a nice
luxurious shower. And of course, with 2 heating systems in series,
either one can break down and the shower still works.

Is this ever done?
Is it workable?
Why isnt this a common arragement? I realise todays lec showers arent
designed for this, but with a suitable model it looks like a sound idea
at first whatnot.
