1. The radiator temperature control valve is not opened
If the temperature control valve cannot get hot when the radiator is not opened, the solution is to open the temperature control valve, which is usually closed clockwise and opened counterclockwise.
2. "Gas blockage" phenomenon
To solve the "gas blockage" problem, we can handle it by ourselves, and the handling steps are as follows:
① Turn off the heating valve at home
② Find the radiator vent valve, generally in the upper left or right end of the radiator
③ The basin ready to receive water can be held by oneself or placed under the vent valve
④ Use a matching screwdriver to gently loosen the vent valve, and stop twisting after hearing the sound of gas discharge
⑤ After the gas is discharged for a period of time, there will be water flowing out. When the water flow is stable, close the vent valve. If the heating can not be heated once, you can put more water, and the heating will be heated slowly.
3. Blocked by debris
If the first two cases are ruled out, then the radiator may be blocked. At this time, we need to find professional maintenance personnel to handle the sundries. Don't screw the heating valve or bolt without understanding, otherwise serious water spray may occur.
4. The resistance of each heater is not uniform (one group is not hot)
At this time, we need to adjust the water inlet valve of each radiator, turn down the valve of the first group of radiator, and turn up the valve of the later radiator.
