<P>PROBLEM TO BE SOLVED: To provide a water heater that can supply an inorganic compound or the like and is compact in size and low in running cost without an electric circuit. <P>SOLUTION: The water heater includes: a hot water supply channel 39 from which hot water is supplied; a melting device 16 which melts the inorganic compound 11 in the hot water; a branch circuit 15 which is formed so that the hot water from the hot water supply channel 39 is diverted; a flow passage resistor 50 which is formed in the hot water supply channel 39 where the melting device 16 is disposed at the branch circuit 15 and the hot water from the branch circuit 15 is returned to a position in a range within a length shorter than a flow path diameter of the hot water supply channel 39 from a downward side end of the flow passage resistor 50. <P>COPYRIGHT: (C)2013,JPO&INPIT |
