。By the way, generally speaking, when considering hot water supply on rainy or cloudy days, as shown in Figure 1, auxiliary heat is connected to the hot water supply pipe 6: Ij4 & O.
Gas instantaneous water heaters that do not take into account connection with solar heat storage devices cannot be connected due to the following problems: If the temperature of fluid A is high, connecting it to the gas water heater may cause the risk of boiling, and due to the heat resistance of the drawing material of the gas water heater, it may cause malfunction or shorten the service life. Ta. Additionally, gas instantaneous water heaters that take heat resistance into consideration and have temperature control (equipment) will solve the above problems, but even if reheating is not required, gas hot water cannot be passed through. At that time, the high-temperature water radiated heat in the heat exchange section of the gas water heater, resulting in wasted energy.

When the temperature of fluid A is lower than Tc, it flows into one inlet d of temperature mixing valve Nsv via a-1) of temperature switching valve CV. Although the mixing valve MV requires reheating, it is an auxiliary heat source device 23.
If the inlet water temperature is high, the low temperature water stored in the water supply tank 11 is appropriately mixed to adjust the temperature to a predetermined temperature. At this time, the opening operation of the other inlet port e of the mixing valve MV is sensed by the pump control means F'SI such as a pressure switch, and the water supply pump PMI is operated. In addition, the temperature of fluid A or the set temperature T
If it is lower than M, the inlet port (e) is closed, d-4 is opened, the pump PMI is stopped, and the fluid A flows directly into the auxiliary heat source device 23 without being mixed, where it is reheated and then supplied to the hot water faucet. Supply to 18.
