I. Is it useful to release water when the heating is not hot?
1. The heating is not hot, do not blindly release water
The heating is not hot The main problem is the accumulation of gas in the pipes, which leads to poor water circulation. When residents put water on the radiator, what is actually released from the radiator is gas, but the amount of water released is very small. Some residents do not understand. Insufficient storage, resulting in the heating not reaching the temperature it should be.
There are many reasons why the radiator does not heat up. Water cannot be released without authorization. If water is released without authorization, it will cause water loss in a certain part of the system, resulting in changes in the pressure of the heating system and a large amount of heat in the pipe network. The water is lost, which in turn causes the radiator to become less and less hot.
In addition, the water in the radiator has high temperature and high pressure, and also contains chemicals that are harmful to the human body. Therefore, it is best not to release the water in the radiator at will.
2. The key is to release air if the heating is not hot.
If the heating in the home is not hot as a whole, it may be because the outdoor water inlet and the return water valve are not open; The local part is not hot, which may be due to the fact that the top layer is not vented; the radiator is half hot and half cool, because the air is collected from the tail. Generally speaking, in the case of ensuring the circulating pressure and temperature, the main reason why the heating is not hot is the air blockage, and the gas accumulation in the discharge pipe is sufficient.
Second, how to properly discharge water on the radiator
The specific method of venting if the radiator is not hot is as follows: each radiator has a manual exhaust valve. The user can gently loosen the manual exhaust valve, and immediately stop twisting the exhaust valve when the exhaust sound is heard. If there is a steady water flow out, the exhaust valve can be gently tightened. After exhausting the air, if the radiator is still not hot, you should ask a professional to find out the reason and help solve the problem, and you must not blindly drain the water.
Generally speaking, don’t let water at will when the heating is not hot, mainly to deflate the radiator. It is understood that the indoor temperature of residents is above 16°C, which is the standard heating temperature. Although the room temperature can be maintained between 18°C and 20°C, there are many residents who are still dissatisfied. I remind all heating users that the higher the heating temperature, the better. Well, under normal circumstances, the indoor temperature is kept at 18°C-24°C, and the humidity is kept at 50%-60% for the most comfortable.
