At what temperature does flue gas condensate?

Furthermore, at what temperature does a boiler condensate? Condensing boilers require entering water temperature (EWT) in the 100˚F (55˚C) range to actually condense water out of the exiting flue gas. The onset of condensing is with an EWT of about 130˚F (54˚C), but maximum efficiency occurs at an EWT of 80˚F (27˚C) or lower.
