With a back boiler, what causes lots of noise? The back boiler is between 10 - 12 years old.
From your description, it sounds as though you have air in the central heating system which is causing the "water whooshing" noises as the pump circulates water (and air) round the radiators. You can remove air in the system by "bleeding" the radiators using a special "key" (you should have one but if not B&Q or other DIY places sell them) to open the small air bleed valve at the top of each radiator (best done with the heating off and radiators cold (or cool).
There is a handy guide to this procedure on the British gas website at http://britishgas.home-maintenance.info/heating/radiator-bleeding/ - better than me describing it again!
If this fails to improve the situation you should contact a registered gas installer to inspect the system and advise as there may be a leak which is letting air in, or the noises may be due to another problem.
