Web1. Higher Heating Value vs. Lower Heating Value A critical value used in applying the thermal efficiency standard is the “total energy input” for the year for which thermal efficiency is being calculated. One of the first steps in determining the total energy input for a unit is identifying the unit’s fuel mix and the heat content or heating WebThere are two kinds of enthalpy of combustion, called high (er) and low (er) heat (ing) value, depending on how much the products are allowed to cool and whether compounds like H. 2O are allowed to condense. The high heat values are conventionally measured with a bomb calorimeter. Low heat values are calculated from high heat value test data.
