Along the flowing direction of water, the water flow sensor 30 is disposed far away from the bathroom water inlet 4211 relative to the water replenishing valve core 60. When the bathroom water inlet 4211 supplies water to the heating channel, water directly enters the heating channel from the bathroom water inlet 4211, and cannot pass through the water flow sensor 30, so that misjudgment of the water flow sensor 30 cannot be caused. It can be understood that, if water passes through the water flow sensor 30 during water replenishment along the flowing direction of water, the water flow sensor 30 may mistakenly assume the water flow when the water enters the flow passage 4213 from the bathroom water inlet 4211, then flows into the bathroom channel, and flows out from the bathroom water outlet 14.

In one embodiment, the water flow sensor 30 is disposed within the outlet passage 15, i.e., the water flow sensor 30 is disposed within the first valve 101.

One end of the water replenishing valve core 60 extends into the water replenishing valve body 422 and can move in the water replenishing valve body 422, so that the flow passage 4213 is communicated with or separated from the water replenishing passage 4221, and the flow passage 4213 can replenish water to the water inlet passage 4212 through the water replenishing passage 4221. Through setting up moisturizing valve body 422 and moisturizing case 60 on second valve 401, then need not to set up moisturizing valve body 422 and moisturizing case 60 again on the first valve 101, simplify the structure of first valve 101 for first valve 101 has sufficient space and sets up power interface 13.

When the water replenishing valve core 60 blocks the water replenishing hole 4222, the flow passage 4213 is communicated with the water replenishing channel 4221 through the water replenishing hole 4222, and when water replenishing is not needed, the water replenishing valve core 60 moves to block the water replenishing hole 4222, so that the flow passage 4213 is separated from the water replenishing channel 4221 and is separated from the water inlet channel 4212.

A portion of the valve body 421 extends toward a side away from the third heat exchange port 44, and the water replenishing valve body 422 is connected to a side of the valve body 421 away from the third heat exchange port 44, that is, the water replenishing valve body 422 is located on a front side of the second valve 401, so that the width of the second valve 401 as a whole is reduced.

First intercommunicating pore 4114 has been seted up to the wall in heating chamber 4113, has seted up second intercommunicating pore 4115 on the wall in second chamber 4112, and second valve body 40 still includes bypass valve body 47, has bypass runner 471 runner 4213 in the bypass valve body 47, and bypass runner 471 runner 4213 communicates with heating chamber 4113 through first intercommunicating pore 4114, and communicates with second chamber 4112 through second intercommunicating pore 4115 to communicate with inhalant canal 4212. When the water pressure in the inlet port 43 is high, the three-way valve element 50 cannot move down due to high pressure, the driving mechanism 70 will work all the time, and the driving mechanism 70 is damaged, and the bypass flow channel 471 flow channel 4213 can increase the pressure in the second chamber 4112, so that the three-way valve element 50 cannot move down due to high pressure can be avoided, and when the water in the heat exchanger 201 is lack of water and is burnt, the water is supplemented to the water outlet flow channel 4213 through the bypass flow channel 471 flow channel 4213, so that the water is supplemented to the heat exchanger 201.

The bypass valve body 47 is arranged on one side, far away from the second valve body 40, of the three-way valve body 41, so that the maintenance is convenient, and the whole three-way valve body 41 is not required to be detached during the maintenance.

The axis of the bypass valve body 47 is arranged obliquely with respect to the axis of the three-way valve body 41, so that the bypass valve body 47 abuts against the three-way valve body 41, reducing the width of the second valve 401, making it compact.

Preferably, a check valve 472 is disposed in the flow passage 4213 of the bypass flow passage 471, so that not only a water replenishing function is realized, but also water can be prevented from flowing back into the heating chamber 4113 from the second chamber 4112.

The wall-mounted boiler system 100 further includes a heating module 901 and a radiator 902, the heating module 901 is located at one end of the heat exchanger 201 close to the power element 80 and is connected to the inlet of the power element 80, one end of the radiator 902 is connected to the heating outlet water, and the other end is connected to the inlet of the power element 80.
