In terms of energy efficiency, why is it beneficial for boilers to operate at higher efficiencies?

Boilers that operate at higher efficiencies utilize fuel more effectively, translating directly into lower fuel consumption. When a boiler operates efficiently, it means that a greater portion of the energy in the fuel is converted into useful work—such as heating water or air—rather than being lost as waste heat. This results in significant reductions in energy costs, as less fuel is required to achieve the same heating output.

Moreover, operating at higher efficiencies not only saves money on fuel but also contributes to environmental sustainability by decreasing the overall demand for fuel resources and reducing greenhouse gas emissions. Therefore, the operation of boilers at higher efficiencies is advantageous both economically and environmentally, making this choice the most appropriate in the context of energy efficiency benefits.
