Would a high flow system like Bosch 440 cope with 14 radiators and 2 shower or do i need an unvented system?

Alright, yer i think the worchester 44 would be ok but i carnt realy fault unvented systems only for there price but i think i system tht big and u have the money id get an unvented as the water pressure for ur hot is the same pressure as ur cold and they do belting showers, and the advantages are greater than the disadvantages.
Thanks tosh....i was thinking of a veismann 333f as that has a 120 litre built in.....i am confused
Dont suppose yo work over the water do you?

The 440 will cope with two shower no problem and do 14 rads. There are other high flow combis around:
Alpha cd50 (wall)
Vaillant 837 (wall)
Vaillant 937 (wall but huge)
Ethos 54 kW (wall and highest flowrate for a instant combi)
Broag 39C (wall)
W-B 42kW (wall)
W-b 440 (wall)
Viessmann 333 (floor)
Glow Worm ultrapower (floor)
Or simply two cheaper combis. See:

What didn't you understand?
If money is no object go for the unvented scenario. Always the best bet.
Whatever you decide on you will need the same good flow and pressure on your cold mains supply ie at least 20 l/min and hopefully at least 3 Bar pressure.
