What are the common faults of heating and their elimination methods?

First, the common faults of heating and their elimination methods?

1, common fault: the heating is not hot as a whole.

Troubleshooting: Open the inlet and outlet valves.

2. Common faults: the heating is not hot (the valve has been opened); The heating is less than half as hot; There is the sound of water in the heating.

Troubleshooting: There may be gas in the heater, which needs to be deflated.

Method 1: first close the water inlet valve, open the air valve to exhaust, and close the air release valve when the water overflows.

Method 2: Close the inlet valve by 3/4, then close the return valve, open the air valve to exhaust, and close the air release valve when the water overflows.

Note: After operation, if the fault cannot be eliminated, notify the maintenance personnel.

3. Common fault: the temperature of the heating pipe is not enough and the room temperature is too low.

Troubleshooting: the inlet water temperature is low, increase the inlet water temperature, and check the system.

4. Common fault: internal leakage of water inlet valve (near the heating direction).

Troubleshooting: Close the inlet and outlet valves before maintenance.

5. Common faults: water leakage outside the inlet valve and the return valve (near the main pipeline)

Elimination method: notify the heating unit and the property to assist in maintenance.

Second, why is there water in the radiator not hot?

The water in the radiator is different from domestic tap water, and it needs to be circulated to keep the indoor temperature. If there is air in the pipe network, it will cause air resistance, and if there is dirt, it will cause scaling and poor circulation. If the water cannot be circulated in time, the water in the radiator will gradually decrease due to the refrigeration temperature, which will lead to the decrease of the room temperature. Therefore, the exhaust valve must be opened in the building or outdoors to exhaust the air in the system. If the effect is not good, the heating pipe network and radiator can be cleaned and descaled, so that after the system circulates smoothly, the radiator temperature will return to normal and the room temperature will also rise.
