Do I need to close the valve after stopping heating?

For central heating system, it needs to be shut down.

1, to prevent the water in the pipeline from decreasing, which is not conducive to the system anticorrosion and temperature guarantee in the heating season. Generally, the set temperature of central heating is about 18 degrees, so there is a great temperature difference between the water in the heating pipeline and the water in the natural environment, and the volume of heating water will expand under the action of thermal expansion and cold contraction. When heating is stopped, the water pressure of the whole heating pipeline system will drop, and the heating pipeline in the user's home will also drop.

2. Prevent the pipeline from entering too much air after the heating is restored. When the pipes in the user's home are in a state of water shortage, when heating is resumed in the second year, the heating supervisor will inject more water into the heating channel, and new air will enter the heating channel at the same time. Because the heating channel is in a circulating state, some air will gather at the corner of the heating channel and some low points, which will easily cause airflow blockage, affect the heating and heat dissipation of the heating, and cause the temperature of the heating to rise abnormally and at the same time.
