As shown in Fig, for the home water supply system installed with the intelligent temperature control valve of H-type water return system, in order to effectuate the use of hot water in the remotest main washroom, the user should turn on the faucet for 2-6 seconds and then turn it off, so that the water flow switch could sense the flow state of water in the pipeline, transform the flow state into an starting signal, and transmit the signal to the temperature control cycle control box, which will start the circulating pump. However, what is different from the existing ordinary home hot water circulating system is that: When the temperature of the residual water in the hot water pipe in the remote main washroom is lower than the opening temperature of the valve, the valve opens, and the residual low-temperature water in the hot water pipe will be pumped back through the intelligent temperature control valve of H-type water return system, and the main cold water pipe connected with it, to the water heater to be reheated. Meanwhile, the hot water in the water heater also flows timely to the remotest main washroom. When the hot water flows through the intelligent temperature control valve of H-type water return system, as the temperature of hot water is higher than the closing temperature of the valve of H-type water return system, so the valve is closed at the moment and the hot water flows directly into the hot water pipe in the remotest main washroom, enabling the user to enjoy warm or hot water in time.
