FWIW - 4 bed house, 2 bathrooms + ensuite, just had a Alpha CD50 fitted,
bath filling is on a par with the old cylinder system, its wall mounting
and stuck in the loft on the gable wall - worth a look

You must have had a very poor 'cylinder system'. A correctly designed one
should have given twice the flow at double the temperature of an Alpha
CD50 thus filling a bath to the wanted temperature in a quarter of the
time.

Only if the cylinder is on the wall the other side of the bath taps, the
bath taps are wide bore, high flow, low pressure taps, The cold water tank
is directly above the cylinder and the cold feed is 28mm. Most are not like
that and just one 22mm elbow can reduce the flow quite a bit. Have the
cylinder and tanks away from each other and the bathroom down the hall and
the flow is greatly reduced to that about the same as the Alpha CD50.
