Principals of Condensing Boiler System Design

2017-6-16 · ANSI Standard Z21.13 tests and rates condensing boiler performance with an 80˚F (27˚C) boiler entering water temperature (EWT) and a 100˚F (55˚C) temperature rise (delta-T) to produce a boiler leaving water temperature (LWT) of 180˚F (82˚C). Condensing boiler performance is dominated by the boiler EWT. Figure 1 below shows a typical
