The value is methodological: define a benchmark, measure actual performance, and diagnose the gap. Do not adopt workbook constants without checking. Fresh full-page audit: PDF90 Fahrenheit temperature reduction is not percentage heat loss; p98 Table112 energy conversion is wrong. Fitted heat capacity and assumed losses are not independently measured efficiency.
Energy calculations and operating observations.
The manual compares theoretical and observed heating duties, fuel or electrical inputs, losses, and run-time data to show that efficiency must be measured rather than assumed.
