PURPOSE:To prepare effectively for a temporary use of larger amount of water, by heating forced circulation by means of temperature adjusting device. CONSTITUTION:When a larger amount of water is used, the supplied waters are flowed through a tank 1 by a partition plate mounted to a water intake 2, and forwarded to a heater 10 through a circulation hole 4 as the circulation waters. Before the heater 10 a portion of the circulation waters are sent to a temperature room 26 to take the temperature thereof. When they are found to be of lower temperature, the heat media increases by means of the heat media adjusting device 14 instructed by a temperature setting device 25 to heat the low-temperatured circulation waters flowed to the heater 10. Thus while the water supply is made and the returned waters are flowed, the flowed low-temperatured waters can be heated without lowering the temperature of the tank 1 and the heating can be kept upto the set temperature, because the heat media are supplied to the heater 10 as needed on the detection of the temperature of the circulation before these low-temperatured waters are supplied to the heater 10. Thus the temperature difference in the tank 1 can be prevented. |
