The working process is that the backwater circulating pump 13 is started, water in a section of pipeline from the cold water pipe to the one-way valve can enter the heat storage water tank, the one-way valve is opened, and water in the hot water pipe can enter the cold water pipe and be recycled into the heat storage water tank together. Therefore, before the water is used, the water which dissipates heat in the hot water pipe can be recovered, and the hot water in the heat storage water tank can be supplemented into the hot water pipe in time, so that the water heater is convenient for users to use.

In order to realize automatic control, a backwater temperature sensing probe can be arranged at the position where the one-way valve is connected with the hot water branch pipe, and the backwater mode can carry out two operations of periodically returning water and instantly returning water according to habits of users.

Time-phased and timed water return: a user sets a backwater temperature and a function opening time period according to own water use habits, and a backwater circulating pump is opened when the temperature detected by a backwater temperature sensing probe is lower than a set temperature in the opening time period, so that a backwater function is realized;

instant water return: when a user uses hot water, the return water circulating pump is opened, and is closed when the detected temperature reaches the set temperature, and the return water circulating pump is closed, so that the user can use the hot water immediately.

Example 2
