does ceiling height matter in radiant heat calculations.

great room has a 23ft high ceiling will that effect heating load

    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.

    No distance does not matter . Mass heats the cooler mass .

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