<p>PROBLEM TO BE SOLVED: To provide a technique capable of efficiently supplying a heating medium at an appropriate temperature to a heating terminal.SOLUTION: A heating device comprises: a heat pump which heats a first heating medium; a heat exchanger which exchanges heat between the first heating medium and a second heating medium; a forward heating passage and a backward heating passage which circulate the second heating medium between the heat exchanger and a heating terminal; a combustion device which heats the second heating medium sent to the heating terminal through the forward heating passage; a bypass route which sends the second heating medium from the backward heating passage to the forward heating passage by bypassing the heat exchanger; a first temperature sensor which measures a temperature of the second heating medium flowing through the forward heating passage at an upstream side of a connection point between the forward heating passage to the bypass route; and a controller. The controller: determines a corrected target temperature by adding a target temperature requested through the heating terminal to a temperature change in the second heating medium flowing through the forward heating passage due to confluence thereof from the bypass route; and controls a heating quantity of the second heating medium with the heat exchanger so that the temperature measured by the first temperature sensor becomes equal to the corrected target temperature.</p> |
