<p>PURPOSE:To reserve hot-water while using water having a given temperature, by a method wherein the supply of water is controlled by the temperature of hot-water in a tank until the amount of water in the tank attains a given amount. CONSTITUTION:The supply of water is controlled by the temperature of hot-water in a tank until the amount of water in the tank attains a given amount (full amount is about 370l). The supply of water until the level of the water attains a full level is effected by constant temperature type water supply system in which the system is operated (water is supplied) when the temperature of hot-water in the tank is 85 deg.C and the operation of the system is stopped when the same is 80 deg.C. The amount of water in the tank is increased stepwise. After the level of the water has arrived at the position of a full level, which is detected by a full water level detecting sensor 73, the level of water is kept while keeping the temperature of the water at 87 deg.C, for example, by controlling the ON/OFF of a heater through a normal thermostat system. A water level switch 81, controlling the starting and stopping of the supply of water and positioned below a temperature switch 80, is put OFF by the full level signal of the full level detecting sensor 73; therefore, the operation of a solenoid valve 95 can net be effected by said temperature switch 80 when the water in the tank is full, whereby the water can not be supplied.</p> |
