Moreover, the heat loss of piping varies depending on the climate, so it has the disadvantage that it cannot be determined unconditionally. Furthermore, the temperature rise at the hot water faucet at the start of hot water supply is significantly delayed, as shown by the solid line in FIG. This is because the heat capacity of the piping is larger than the heat capacity of the water heater, and the amount of heat generated is controlled by the temperature of the hot water outlet of the water heater. In other words, even if the temperature of the hot water at the outlet of the water heater has reached the set value, the temperature of the hot water at the hot water faucet has not yet reached the set value, but the amount of heat generated is suppressed.

With this configuration, the heating amount of the water heater is controlled by the average temperature over the entire length of the piping, so hot water is supplied to the usable temperature at the hot water faucet, and the water heater heats the water in consideration of the heat capacity of the piping. In order to be
The time required for the tap water temperature to reach the usable temperature is short, and hot water can be heated quickly.

Next, the state in which hot water is supplied by the hot water supply system with the above configuration will be explained using FIG. Either the hot water temperature rises rapidly, or the hot water temperature from the hot water tap 6 gradually rises with a delay due to the heat capacity of the piping, and even if the hot water temperature at the water heater outlet 2 reaches the set usage temperature, it will be much higher than the set value. is seperated. As shown by the solid line in the figure, in the conventional system, the amount of heat generated is throttled from this point on, so the rate of rise in the temperature of the hot water at the hot water tap 6 is suppressed, but in the system of the present invention, as shown by the broken line in the figure, Since the control valve 4 is operated at the average temperature of the piping, the temperature at the water heater outlet 2 rises until this average temperature reaches the set value, and the water temperature at the hot water tap 6 reaches the set value in a short time. Once the temperature is reached, the temperature can be set to the temperature that will actually be used.
