Principals of Condensing Boiler System Design
As gas temperatures continue to drop more water is condensed out and the boiler efficiency increases dramatically down to about 80˚F (27˚C) which is the boiler EWT at which the boiler is rated. If the heating water system cannot deliver 80˚F (27˚C) water back to the boiler the boiler will not operate at it s rated efficiency.
