A heat-pump type heating apparatus, having: a heat-pump refrigerant circuit, within which are connected a compressor (11), a heat-exchanger (14) for conducting heat-exchange between a refrigerant compressed within the compressor (11) and a fluid, a decompressing apparatus (17) for decompressing the refrigerant conducted with the heat-exchange, an evaporator (20) for conducting heat-exchange between the refrigerant decompressed and an air, through refrigerant conduits, provided therebetween; a heating circuit (3), within which are connected a circulation pump (41) for sending the fluid to the heat-exchanger (14), an heating terminal (48) , having a fluid inlet, into which the fluid heated within the water-refrigerant heat exchanger (14), and a fluid outlet, from which that fluid flows out, for radiating heat of that fluid,through conduitsprovided therebetween;an operation controller means (5) for operating and controlling equipment of the heat-pump refrigerant circuit and the heating circuits (3) ; and a circulation flow-rate controlling means for controlling the circulation pump (41) upon basis of fluid inlet temperature and fluid outlet temperature of the heating terminal (48), or in addition thereto a room temperature of a room where the heating terminal (48) is installed; thereby providing the heat-pump type heating apparatus enabling to obtain high efficiency of the equipment. |
