<p>PURPOSE:To permit to supply hot-water having uniform temperature without enlarging the volume of hot-water reserving tank by a method wherein a means to flow hole of hot-water in the hot-water reserving tank and a means to flow the hot-water under whirling are provided in the device. CONSTITUTION:The device is constituted so that a part of hot-water in the upper part of the hot-water reserving tank 1 is upplied to a delivery port 7A through a regulating valve 8, a pump 9 and a rotor meter 10 to flow whole of the hot-water located in the upper and lower parts of the hot-water reserving tank 1 in order to mix them while a part of the hot-water, located at the lower part of a heater 2, is extracted through the regulating valve 11, pump 12 and the rotor meter 13 to release the extracted hot-water into the lower side of the heater 2 and effect forced flow of whirling flow system. The ratio of the whole flow and the whirling flow is changed by controlling the regulating valves 8, 11 in accordance with a temperature distribution in the tank 1, which is detected by temperature detectors 5a-5e, whereby the temperature distribution of the hot-water in the hot-water reserving tank 1 may be uniformed.</p> |
