the jacket losses of the boiler. Based on ANSI Z21.13. For boilers 300,000 to 12.5 million Btu. • A.F.U.E. – The measure of annual efficiency of a boiler that takes into account the cyclic onoff operation and associated losses as it responds to changes in load. For boilers under 300,000 Btu

Essentially the boiler model provides a first order approximation of performance for fuel oil, gas, and electric boilers. Boiler performance is based on theoretical boiler efficiency and a single quadratic fuel use-part load ratio curve represented in the equation above.

• ### Principals of Condensing Boiler System Design

Figure 1 Typical Condensing Boiler Efficiency Curves The boiler starts to condense water out of the combustion gasses when the dewpoint of the combustion gasses is reached; which, at sea level, is about 130˚F (54˚C). 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 …

The coefficient values there give a very different curve for a condensing boiler, ie. Eff = 96% at 0.1 cartload and Twater = 50oC. My overall aim is just to model a non-domestic condensing boiler that is available in the UK but unfortunately have very little data on efficiency: Boiler efficiency Part load 30% at 50/30°C (gross) 97.4 %
