The present invention provides a heating device to supply a heat medium at a proper temperature to a heating terminal with an excellent efficiency. The heating device comprises: a heat pump; a heat exchanger; a heating reciprocal path; a heating double path; a combustion device; a bypass path; a first temperature sensor; and a controller. The heat pump heats a first heat medium. The heat exchanger performs heat exchange between the first heat medium and a second heat medium. The heating reciprocal path and the heating double path circulate the second heat medium between the heat exchanger and the heating terminal. The combustion device heats the second heat medium transferred to the heating terminal through the heating reciprocal path. The bypass path bypasses the heat exchanger from the heating double path and the heating reciprocal path to transfer the second heat medium. The first temperature sensor measures the temperature of the second heat medium flowing on the upside of the heat reciprocal path, which is above the connection position between the heating reciprocal path and the bypass path. The controller determines a correction target temperature by adding a temperature change, which is generated in the second heat medium joined from the bypass path to flow in the heat reciprocal path, to a target temperature required by the heating terminal. The heated amount of the second heat medium in the heat exchanger is controlled to allow a measured temperature by the first temperature sensor to be the correction target temperature. |
