<p>PURPOSE:To save charge for electricity and improve the durability of a bath device by a method wherein additional heating is stopped and hot-water outputted from a hot-water reserving tank is poured directly into a bathtub through a hot-water pouring opening and closing valve to achieve a set temperature when a temperature setting in the bathtub is set so as to be higher than a hot-water temperature in the bathtub by a given value or more, in the operation of the bath device, utilizing a hot-water reserving type water heater, for obtaining the set temperature in the bathtub. CONSTITUTION:When a temperature in a bathtub 7 is set so as to be higher than a temperature in the bathtub, which is detected by a temperature detector 14, by 3 deg.C or more, a hot-water supply regulating valve 19 is fully opened and a feed water regulating valve 20 is fully closed by the signal of a controller 21 while a hot-water pouring opening and closing valve 16 is opened to pour high-temperature hot-water from a hot-water reserving tank 1 into the bathtub 7 directly. In this case, a circulation pump 10 is operated and only when a temperature detected by the temperature detector 14 has arrived at the set hot-water temperature in the bathtub 7, the hot-water pouring opening and closing valve 16 is closed and the operation of the circulation pump 10 is also stopped by the signal of the controller 21.</p> |
