Abstract: A method of utilizing the high energy values of fossile fuels in central heating boiler systems. The boiler system comprises a processor which includes an air heat pump (5) which functions to cool the system flue gases by condensation. A first fan (10) generates a first circulation (C.sub.1) of boiler room air, via the air heat pump (5), this circulation of air also passing through a heat exchanger (4) where heat exchange takes place with the flue gases. A second air circulation (C.sub.2) is generated with the aid of a flue-gas fan (7) which removes flue gases from the boiler by suction, thereby generating a subpressure in the boiler room so that fresh air will be drawn in from the ambient surroundings, this air passing through the heat exchanger (4). A lower pressure is maintained on that side of the heat exchanger (4) on which the air/flue gas mixture (C.sub.
