If you go tank cylinder then use a Fortic type of tank/cylinder combination
unit (this is all one insulated unit and can go in the loft) with an
integral quick recovery coil. Have a combi (Worcester Junior is having good
reports of late; and simple) heat the cylinder as per usual, but with a
priority system of DHW. have the shower only through the water section of
the combi giving high pressure showers and all other hot outlets from the
tank/cylinder. You only did high pressure at the shower, all the rest need
volume not pressure.

How do you get a combi boiler to heat a cylinder?
