The cold winter is the time when it is most needed, so families with warm homes will be able to use it. Because the floor heating can bring good enjoyment to our life, but some families will encounter the problem that the geothermal return pipe is not hot during the use of floor heating. So, what is the reason why the warm water return pipe is not hot? How should we solve it? The following will be answered by Xiaobian.
1, the pipeline pressure is not enough
Phenomenon: Some households have high floors, or the pressure of the district heating pipes is not enough, so it is easy to lead to unsatisfactory heating.
Warm water return pipe is not hot Solution : In case of this kind of situation, you need to find a heating company or find a property to solve it. If it cannot be solved, it is recommended to install a circulating pump to increase the circulation of hot water to achieve the desired heating effect.
2, gas in the pipeline
Phenomenon: The warmth of the main bar heat, and the back bar is not hot, there is a gas in the pipe top, leading to hot water can not enter the loop, so that the warm water return pipe is not hot.
Warm water return pipe is not hot Solution : Close the water return valve first, then open the floor heating valve to exhaust. After the air in the floor heating pipe is completely drained and the heat is applied, the effect is observed. In many cases, the return pipe is not hot and is related to the exhaust gas.
3, filter clogging
Phenomenon: The main bar of the water supply is not hot, and it may be that the hot water supply is too dirty, causing the filter to clog and preventing it from functioning properly.
To warm the return pipe is not hot Solution : Open the filter with a live spanner, then clean the filter inside, clean it and reinstall it; if you are in trouble, you can also find a professional to clean it.
4, to warm long-term cleaning
Phenomenon: The long-term contamination on the inner wall of the pipeline will gradually narrow the inner diameter of the floor heating pipe, the water flow will become smaller and smaller, the temperature of the floor heating system will decrease, and even the pipeline of the floor heating will be emboldened.
Warm water return pipe is not hot Solution : In general, the floor heating pipe should be cleaned once in 3-5 years. Of course, it is best to find a professional floor heating company to perform the maintenance and maintenance of the floor heating equipment before the annual heating.
5, loop uneven
Phenomenon: The heating effect of other users in the same community is good, but the effect of home is not good, there may be uneven heating circuit construction.
Warm water return pipe is not hot Solution : Use a small valve on the floor warm water separator to adjust the circulation of each circuit so that it can be evenly cycled to achieve an ideal heating effect.
Xiao Bian concludes: The above is the reason why the warm water return pipe is not hot and the warm water return pipe is not hot solution method . Hope that the above content can help the needy friends, can help everyone solve this trouble, and then let Everyone can spend a comfortable, warm winter.
