Should I fill the wall-hung boiler with water in summer? How to fill the wall-hung boiler with water?

The domestic hot water heat exchanger of wall-hung boiler is different from the heat exchanger of heating system. The domestic hot water heat exchanger is heated by the main heat exchanger of heating system through water circulation. You can refer to the operation of the wall-hung boiler. Don't stop adding water as soon as the red light goes out. Always observe the water pressure gauge, and close it when the water pressure reaches 1.5- 1.7 to avoid frequent water addition.

You don't have to turn off the water when the wall-hung boiler is filled with water. We only need to open the water replenishing valve to replenish water, and then stop replenishing water when the pressure reaches 1.5 bar. When the wall-hung boiler is not working, the water pressure is 1. 1~ 1.5Kg. After working, the hot water makes the pressure rise, and the water pressure reaches 2.5Kg. If the pressure gauge value exceeds 3 or even reaches 4, it means that the air bag is short of air, and it is necessary to inform the technicians to replenish air. Plug in the power plug of the wall-hung boiler; Adjust the working mode to summer mode (hot water mode); Check whether all pipeline valves are open.

If a circulating pump is installed in the wall-hung boiler, it can automatically add water. As long as the water pipe is connected with the water pipe of the circulating pump, the water can be replenished automatically. Turn off the main switch at home first, and then find out the water inlet valve of the bottom wall-hung boiler. Then turn it in the "open" direction, the main purpose is to open the water valve. Finally, you should pay attention to the pointer deviation of the water pressure gauge, and wait until the pointer stops at a suitable water level, because we need to turn off the power supply of the wall-hung boiler before adding water. However, if there is no electricity in the wall-hung boiler, it means that it has some faults and should be inspected and repaired after water is supplied.

If a circulating pump is installed in the wall-hung boiler, it can automatically add water. As long as the water pipe is connected with the water pipe of the circulating pump, the water can be replenished automatically. If you want to fill the wall-hung boiler with water, you should first open the water supply valve of tap water to the wall-hung boiler, and then open the water inlet valve of tap water on the wall-hung boiler.
