Having installed a combi boiler recently we no longer have the backup of the
immersion heater in the cylinder. So we are thinking about installing an
electric shower so that at least that will continue to work should the
boiler not be working for any reason.

However since we are having to modify the bathroom to take the new shower I
would like to make regular use of it, not just in emergencies, it would
probably be best in that case for the shower to be able to run off the hot
water supplied by the boiler.. but should hot water not be available it
should be able to generate its own.

Is there such as thing as an electric shower which can use a hot water input
when it's available?

Cheers

I may be wrong but the simplest way would be to install a normal
thermostatic mixer over the bath or in a cubicle.

The cost of an electric shower is nearly all in the supply installation.

I would install the backup electric shower near the 'normal' one but
remove the outlet hose. When needed you move the hose from the mixer to
the electric unit until the boiler is fixed, keeping the same shower head
and riser rail.
