Burning Efficiency of Liquid Fuel in Heating System with Condensing Boilers

The paper presents the results of a study concerning the efficiency of a heating installation with a condensing boiler using liquid fuel, equipped with an accumulator and burnt gases separator. The given up heat in the gas separator is taken over and accumulated through a heat pump. The energetic efficiency of the primary heating functioning regime was established at 94% after the measurements and at 95.8% through calculus.
