<p><P>PROBLEM TO BE SOLVED: To detect leak abnormality of a heat exchanger for heating hot water in a bathtub. <P>SOLUTION: This heat source device includes: a heat source circulating means 31 for circulating hot water to be supplied through a heat source circulating path 4 in the form of supplying hot water to be supplied, which is heated by a heating means 5, to the heat exchanger 7 for heating hot water in the bathtub and then returning the same to the heating means 5; a bath circulating means 49 for circulating bathtub hot water between the heat exchanger 7 for heating hot water in the bathtub and the bathtub 18 through bath circulating passages 19, 20; and an operation control means for controlling the operation. The operation control means discriminates leak abnormality of the heat exchanger 7 for heating hot water in the bathtub based on change information on a detected value of a water level detecting means 50 provided in the bath circulating passages 19, 30 to detect the hot water in the bathtub or the level of hot water in the bath circulating passages 19, 20 in a leak abnormality detecting timing of the heat exchanger 7 for heating hot water in the bathtub. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
