Water is an essential requirement in everyday life and global demand for clean usablewater is increasing year by year. Therefore, developing and implementing effective water resourcemanagement and conservation strategies is vital. Generally speaking, most individuals (particularlysenior citizens) prefer to use warm water when washing their hands or taking a bath. When hot wateris left standing in the hot water pipe (i.e. the faucet is turned off), it will gradually cool. Consequently,when the faucet is first turned on, the water is generally allowed to run until it becomes sufficientlyhot. Meanwhile, the original cooler water is simply drained away. Clearly, this approach is wastefulof both time and water. Therefore, this paper develops a green storage tank to perform athermo-controlled water supply function. The tank is positioned between the hot water supply and thefaucet and its operation is controlled by an electro-thermal thin-film heater and a thermo-controlledvalve. When the faucet is turned on, the cooler water in the hot water pipe is directed into the tank.Once this water enters the tank, it is mixed with hot water stored inside until it acquires the desiredtemperature. The warmed water is then supplied to the faucet. When the water flowing through thehot pipe to the tank is already sufficiently warm for use, the thermo-controlled water supply functionis automatically overridden, and the warm water is delivered directly to the faucet. The proposedgreen storage tank not only provides effective water and energy resource savings, but also provides amore convenient operation
