<p>PURPOSE:To obtain a desired temperature of a hot water quickly by controlling a mxing valve and a heater through a temperature controlling means according to the temperature of the hot water at the outlet of the mixing value and that at the outlet of a mixed hot water heater. CONSTITUTION:After a hot water feeding temperature is set by a temperature controlling means 6, when a hot water feeding cock 9 is opened, an outlet temperature 7 of a mixing valve 4 is inputted into the temperature controlling means 6 and compared with the set temperature to adjust the opening of the mixing valve 4. An outlet temperature 8 of a heater 5 is inputted into the temperature controlling means 6 and compared with the set temperature to adjust the heat of the heater 5. Therefore, when the hot water from a heat source section 1 exceeds the set temperature, the heater 5 is stopped and the temperature of the hot water can be adjusted only with the mixing valve 4. With such an arrangement, a hot water can be obtained quickly at a desired temperature.</p> |
