<P>PROBLEM TO BE SOLVED: To provide a hot water filling device capable of bringing a hot water temperature in a bathtub at the time of finishing hot water supply close to a hot water filling temperature set by the user even when an outside air temperature at the time of performing hot water filling is different from the outside air temperature of the last hot water filling. <P>SOLUTION: The hot water filling device 10 specifies an outside air correction temperature based on the outside air temperature at the time of performing a hot water filling treatment (S10). Moreover, water supply is started at a hot water supply starting temperature obtained by adding the outside air correction temperature and the last temperature difference read out from the memory to the setting temperature set by the user (S12-S16). When hot water is supplied to a half of a setting hot water amount at the hot water supply starting temperature, a hot water temperature in the bathtub is measured, a hot water temperature correction temperature is specified based on the hot water temperature, hot water supply is re-started at a hot water supply re-starting temperature obtained by adding the hot water temperature correction temperature to the hot water supply starting temperature, and the hot water supply is performed to a remaining half to the setting hot water amount (S20-S26). <P>COPYRIGHT: (C)2012,JPO&INPIT |
