Anonymous users2024-01-23It's too general to ask, it's not easy to analyze, you have to check the power supply, switches, settings, and all aspects.
I can't understand this picture up and down, the position of the knob to see the picture is the position of the exhaust valve, which may be caused by air blockage, and the shape of the nut on the exhaust valve does not need to be tightened, and the tightening cannot be automatically exhausted. If the water leaks can be tightened, the air should be exhausted every few days, the radiator is not hot, the pipe above is hot, and the pipe below is not hot, because there is air in the radiator, if there is no air, the water circulation is slow, and the water pump must be used.
Hello, it may be that the pipes have been rusting for a long time and the water flow is not smooth, which should be this problem.
Is it hot in the other rooms? If the other rooms are normal, then check that the valve is open, and that there is a release valve to release it, and try it.
1. The valve is not opened.
If you encounter a radiator situation at home, you should first check whether the radiator valve is open. The radiator valve is generally a spherical valve, the valve has generally been adjusted before leaving the factory, generally only two directions, the handle is open when it follows the pipe, and the rotation is 90 degrees to close. >>>More
It should be caused by a blockage in the pipe, it is recommended to find a property or heating department to overhaul it!
