A hot water system includes cold water pipes, hot water pipes, a water heater, a pump, a pump control unit and a connection valve unit. The pump is used to increase the pressure of the hot water pipes to a preset higher level than the pressure in the cold water pipes. When hot water is needed, the connection valve unit at the user side is opened to connect the cold water pipes and the hot water pipes, and when the cold water pipes and the hot water pipes are connected, the water pressure difference between them will become smaller. When the pressure difference change is detected, the pump control unit will activate the pump to pump the water in the hot water pipes into the cold water pipes, so the water in the pipes starts to circulate, and the water will flow through the water heater and will be heated. When the heated hot water reaches the user, the pump is stopped. After the hot water is being served or when the water temperature drops down, the pump is again put into normal operation.
