    This might be a daft question ...

    Let's say you extend an area and it now requires 12,000 BTUs, but your existing radiators only give out 9,000. Your boiler has settings 1 - 6 and in the old space you usually ran your boiler on setting 1 as a general rule during winter and that was comfortable. Can you get away with the rads you have by just upping the setting a bit, say to 2? Is it as simple as that?
    Cheers

    Quick answer: No.

    Turning up the boiler will certainly increase the amount of heat given off by the radiator, but it's not that simple. You couldn't achieve an extra 33% as in your example. The Btus that a radiator produces are based on a differential between the radiator and the air in the room. To achieve that kind of increase you'd probably have to be feeding the rad with steam.
