PROBLEM TO BE SOLVED: To provide a bath water filling device capable of improving energy saving by suppressing the operation of water filling heating means as much as possible.SOLUTION: Control means H, upon receiving a water filling instruction, in the case where the temperature of hot water retained in a heat storage tank T is lower than the set target temperature, when it determines that a reheating amount is equal to the set allowable amount or less on the assumption that hot water retained in the heat storage tank T is filled into a bath tub 3 at a set target water filling amount, and then hot water in the bath tub 3 is heated to a set target temperature by reheating means F, fills the hot water retained in heat storage tank T into the bath tub 3 water at the set target water filling amount in a stop state of filling heating means 18, and then executes a heating stop water filling process for heating the hot water in the bath tub 3 to the set target temperature by the reheating means F. |
