My radiators are getting hot but my rooms are not getting hot i have my boiler turned up to max i have changed the pump and my rf stat as i was told this could be the problem the plumber is now saying the system needs flushing but as the rads are hot i dont think this is the case

the system has been working fine for the past 7 years so it is not down to the rad sizes but i have also checked this just in case

bigger radiators i would say. turning the boiler to max will only increase the temp of the rads to so much. the problem is most likely the rad is to small to heat the room. check online for a rad room calculator. and work out the rad size u have to your room size and see what size it should be
