<P>PROBLEM TO BE SOLVED: To provide a water heater that prevents a water-reforming device for adding water-reforming components to supplied hot water from freezing at low temperature. <P>SOLUTION: The water heater includes: a hot water pouring path 11 for pouring hot water; the water-reforming device 17 for adding a function-reforming component to the hot water flowing in the hot water pouring path 11; and a drain device 18 for draining water at least in the water-reforming device 17. The drainage can be carried out with being free from the complication of a water circuit where the water-reforming device 17 is located, and therefore the freeze of a water-reforming circuit is prevented at low temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
