Combi boilers are good for low occupancy but not for high occupancy as won't cope with the water demands of say, a family with teenage daughters all wanting to wash up, bath/shower and maybe using the washing machine at the same time. A conventional system using storage for hot water can cope with peak demands far better.

I'm surprised you say this. I thought the opposite would be true? All my experience of stored hot water is that once its gone its gone. So 1 person can have a bath each night, unless you have an immersion and stick that on and wait an hour or 3 for it to heat up a new tank? and/or its winter and you wait for the tank to heat up again (if the central heating is on).

Have they come on massively in recent times?

I think blackfive meant that conventional hot water storage is better subject to an adequate storage capacity. If one bath drains the tank then it's inadequate. Problem with a combi is the lack of flow if more than one appliance is in use.

Recovery times from empty to full as low as 15 minutes depending on model.

Hot water supplied at mains pressure. Thing of how quickly it will fill the bath and oh those invigorating showers.

Combi? think about that long run off,wasting water,worse if you have a water meter,then the washer kicks in on hot fill and suddenly your shower goes cold...tsk tsk..
