Pluming, and condensing boiler efficiency.

Is it related? I feel that a condensing boiler that plumes a lot may be less efficient than a condensing boiler that hardly plumes at all. Is this statement true? If a proportion of the water vapour condenses outside the boiler then surely you are losing some energy? I'm not sure, what do others think?Don
