WebAug 1, 2006 · Figure 1 depicts a typical efficiency curve for a condensing boiler relative to return-water temperature. Two main points can be gleaned from Figure 1. First, operating a boiler with a return-water temperature above 140 F yields a peak thermal efficiency of roughly 88 percent. That means it basically is performing like a non- condensing boiler. Webair temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air …
WebTypical combination boiler annual efficiency is routinely much lower than AFUE or combustion efficiency, especially for cast iron boilers or boilers with high “mass” and less than 2” of insulation, and for boilers that finish above 120°F when the thermostat is satisfied (AFUE rates boilers with a 120°F return temperature, but they ... Webair temperature of 400°F. From the table, the boiler combustion efficiency is 78.2% (E1). Tuning the boiler reduces the excess air to 9.5% with a flue gas minus combustion air temperature of 300°F. The boiler combustion efficiency increases to 83.1% (E2). Assuming a fuel cost of $8.00/MMBtu, the annual savings are:
