Your existing combi boiler would probably cope with 3 wash basins, you'd only need a seperate boiler if trying to run 3 baths or showers off it.
It's not very likely all 3 wash basins would be running at the same time, or it it did happen, you'd only loose the water pressure to them, shopuld still get hot water, more than enough for a wash basin.
