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 "individual" 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, the bathroom down the hall
and a mixer tap and the flow is greatly reduced to that about the same as
the Alpha CD50.
