    I have a Worcester 25i combi boiler and would appreciate any advice... issue - my hot water isn't hot..
    This last week, its started running luke warm...
    I gave the heating a blast this evening & hoped that it might do something helpful, but no, radiators were indeed red hot... water still only luke warm.

    First thing to try would be a reset.

    I was told - with the heating off, run the hot water and hold onto the heating flow pipe - I think its the thicker left one.
    If that pipe gets hot, one thing it may point to is your diverter valve being faulty.
    A new flap for this is about a tenner and its a doddle to change.
