My brand new 28kw Potterton HE+ combi delivers 14.5 l/min hot water, the new all-systems shower is great, but the bath flow is the only noticable disappointment ;-- basins and sinks and toilet cistern are OK.
Nine radiators are well within its capability.
The water pressure quoted by the plumbers test is 1.95 bar with 5 l/min flow running during the test.
If you DO have lead pipes supplying your house, they will attract a replacement grant thro' your local Council, on health grounds, but often grants are in packages, eg thermal insulation/draught-proofing.
