Condensing boilers achieve high efficiencies by recovering the latent heat (approx. 10 – 12% available) from the combustion process. Based on the observations from the effects of excess air on the dew point temperature, closing the window of condensing (condensing mode) would mean eliminating the opportunity to achieve the highest efficiency possible.
