explanation of boiler efficiency curves examples in EP

Apologies for what is almost certainly a very dumb question but I'm struggling to understand what the boiler efficiency curves in the EP example files actually represent. Looking at InputOutput reference for the formula and plotting the biquadratic condensing boiler efficiency curve data given in the boilers.idf file gives Eff = 112% at 0.1 part load and Twater = 50oC for example.

Pressure Drop Corrections for Glycol in HVAC Systems (Part 1)

Sep 20, 2010· What correction factor do we use for the glycol solution? Table 3 below is a typical published table. The problem with correction factors is they not only change with the fluid and the temperature, but they also change based on velocity. In general, the greater the velocity, the smaller the correction factor. Lets look at an example.
