PROBLEM TO BE SOLVED: To improve the efficiency of a device to heat supply hot water by eliminating a difference between the upper and lower temperatures of bath tube water when operation is effected, in a heat pump bath hot water supplying apparatus to utilize bath tub water for heating of supply hot water. SOLUTION: By a flow of bathtub water blowing toward a bathtub water surface through a discharge opening part 7a of a bath adapter 5 and bathtub water blowing toward a bathtub bottom through a discharge opening part 7b, bath tube water in a bathtub 1 is agitated with high efficiency. When heating operation of supply hot water is effected by utilizing the heat of arm water in the bathtub 1, temperature distribution that the temperature of the bottom of the bathtub 1 is low and a bathtub water surface layer temperature is high is not formed. Thus, a high efficient heat pump bath ho water supplying apparatus can be provided to perform heating operation of supply hot water utilizing the heat of warm water in the bathtub 1 to a maximum limit. |
