    Assuming that the heating load was calculated taking into account the large wall area, the answer is -- not really. There may be some difficulties in getting even heat without draughts, but there have been several commentaries here and elsewhere on ways to heat churches -- @DanHolohan has written a good deal about it.

    I think you may mean comfort. Depends on how you are heating, in-floor, baseboard, panel radiators, or air handlers.

    Everyone knows that hot air rises is why every politician stands before he delivers his speech.

    The thermal envelope, all the surfaces that separate heated space from unheated space need to be calculated. Basement floors also.
