The paper shows a method of the assessment of the energy efficiency of a modernised steam boiler house in which the thermal energy is recovered due to cooling of the flue gas below dew point. In addition to the energy recovery the modernisation also consists of a wet flue gas treatment that ensures a reduction in emissions of particulates and acidic gas. The publication presents the correct and simple indicator for the assessment of improvement of energy efficiency. Additionally some recommendations based on the example of settlement of savings made in hard coal heating plant, equipped with three steam boilers, fire-tube type, with a capacity of 3x3.0 t/h, operating with quasi-constant output during the year are shown.
