Cooling and Heating - Performance and Efficiency Terminology

The combustion efficiency is calculated by determining the fuel gas losses as a percent of fuel burned. [E c = 1 - flue gas losses] Thermal Efficiency (n t or E t) This efficiency term is generally defined as the ratio of the heat absorbed by the water (or the water and steam) to the heat value of the energy consumed.
