A heating apparatus (100) comprising a condensing boiler (20) and a heat pump (50), wherein the primary- circuit water (30) passes through the condenser (62) of the heat pump (50) and is then warmed by the combustion products generated in the condensing boiler (20). The apparatus (100) comprises some devices in which the following heat exchanges occur: a first heat exchange in a heat exchange device (68; 67, 61) between the exhaust gases coming from the condensing boiler (20), on the one hand, and the refrigerant fluid of the heat pump (50), on the other hand; and a second heat exchange, at higher temperature and inside the condenser (62), between the refrigerant fluid, on the one hand, and the water flowing in the primary circuit (30), on the other hand, in order to raise the temperature of the water flowing in the primary circuit (30). |
