PROBLEM TO BE SOLVED: To obtain bath water heating equipment which has a high energy efficiency and, moreover, can heat bath water stably without being affected by an outdoor air temperature and which enables simultaneous execution of heating of the bath water and dehumidification inside of a bathroom and can keep an environment in the bathroom comfortable. SOLUTION: By driving a heat pump circuit 8 equipped with a compressor 1, a condenser 2, an expansion valve 3 and an evaporator 4, thermal energy is absorbed from the air in a bathroom by the evaporator 4, while this thermal energy is released in the condenser 2 provided in a heat exchanger 15 for heating bath water, so as to heat bath water 19 in a bathtub 18 which is circulated by a bath water circulating pump 16. At the same time, the air in the bathroom sucked into an air duct 10 by a blower fan 9 is cooled to a dew-point temperature or below to be dehumidified. |
