<P>PROBLEM TO BE SOLVED: To provide a combustion device not giving an unpleasant feeling to a user by stabilizing temperature of hot water or a heat medium to be supplied to a heating terminal while saving energy. <P>SOLUTION: In this combustion device 1, a circulation circuit is formed between an external apparatus and the combustion device, and the hot water or heat medium heated by a burner 8 is led to flow into the circulation circuit and supplied to the external apparatus. The temperature of the hot water or heat medium flowing in the circulation circuit is controlled by proportional control and on-off control. When the combustion rate of the burner 8 is controlled by the on-off control, the temperature of the burner 8, switched from on to off, is changed according to a relation between the average value Tv of the temperature of the hot water or heat medium flowing in the circulation circuit and a target temperature Ts. <P>COPYRIGHT: (C)2012,JPO&INPIT |
