What is the reason why the floor heating outlet pipe is not hot? Is there any good solution?

How to solve the problem that the floor heating outlet pipe is not hot? There are many reasons, but there are corresponding solutions. I suggest you try them all.

In the cold winter, floor heating can be regarded as a timely help to northern families, and the problem of floor heating is undoubtedly worse. Many families have the problem that the outlet pipe is not hot. The fundamental reason why the outlet pipe is not hot is that the hot water circulation in the pipe is not smooth, that is, the hot water flows slowly in the pipe. There are many specific reasons: there are sundries in the pipeline and the filter screen is blocked; There is gas in the pipe; Insufficient pressure; Uneven circulation and so on. The following households will introduce the corresponding solutions to everyone according to these reasons.

First, there are sundries in the pipe and the filter screen is blocked. This is the same reason that the water flow will become smaller after the faucet at home is used for a long time. Water is usually mixed with impurities such as sediment and rust. In the long run, impurities in the pipeline will precipitate, the filter screen will be blocked, and sundries will adhere to the inner wall of the pipeline. If it is not cleaned in time, the inner diameter of the floor heating pipe will gradually narrow, and the water flow will become smaller and smaller, resulting in poor water circulation in the pipe and the phenomenon that the water outlet pipe is not hot. This situation requires cleaning the floor heating, which is relatively simple to solve.

First of all, we need to find the location of the filter, which is generally located near the inlet pipe valve of every household. After finding the filter, close the valves before and after the filter, and remember to close them tightly. Remove the screen with a wrench. At this point, there is still a certain pressure in the pipeline. Be careful to spray dirty water on your face when you remove it. Remove it, rinse it with clear water, and you can install it. After the installation is completed, first open the valve behind the filter screen (the valve in front will not be opened first), and then open the exhaust valve not far away for exhaust treatment, so as to avoid poor hot water circulation caused by air mixed in the pipeline when removing the filter screen. If the outlet pipe is not hot due to pipe blockage, the heating effect will be greatly improved after cleaning.

When floor heating is used, it should be cleaned and maintained regularly, so that the service life will be longer. There are also many professional products for cleaning geothermal pipelines in the market, which can remove sediment, dirt and scale well and solve the problem that the backwater is not hot due to pipeline blockage.

Second, there is gas in the pipeline. There may be some air after the heating pipe has been vacant for a summer. The gas in the pipe will lead to poor hot water circulation, resulting in the outlet pipe not being hot. In this case, we need to open the exhaust valve to exhaust. First of all, we need to find the heating valve, close the backwater valve first, and then open the exhaust valve carefully and slowly. When the gas in the pipe is exhausted and there are no bubbles in the water, we can close the exhaust valve and open the return valve.

Third, the phenomenon that the water outlet pipe is not hot often occurs in households with insufficient pressure whose floors are too high or in the end heating position. This is because the heating effect is not ideal due to insufficient end pressure. Hot water needs a certain pressure to circulate in the pipeline. Without pressure, hot water cannot circulate normally. This situation can be reflected to heating companies and properties, and it can be solved by installing booster pumps or circulating pumps.

Fourth, the circuit is uneven. If the heating effect of other residents in the same community is quite good, and the outlet pipe of their home is not hot, it may be the problem of uneven circuit during construction. In this case, the small valve on the water separator can be adjusted to achieve the effect of uniform water circulation, thus solving the problem that the water outlet pipe is not hot.

5. There is something wrong with the installation of new floor heating. If the above methods can't be solved, it may be that no professionals were found when decorating and laying floor heating, and improper construction led to pipeline realization, blockage and short circuit, which led to the outlet pipe not being hot. This situation is troublesome, and the whole pipeline needs to be inspected.

The above are the reasons why the outlet pipe is not hot and the solutions. If there are any shortcomings, please leave a message to correct them. If the above methods still can't solve your family problems, please comment on them at the bottom of the article and discuss them together.
