At home, the water in the water inlet pipe of floor heating is hot, and the water in the water outlet pipe is cold. What happened?

The floor heating stopped heating after a period of use. This happens, that is, the water in the water inlet pipe of floor heating is hot, but the water in the water outlet pipe is cold. How did this happen? What shall we do? Let's take a look at how to deal with it!

We don't have to worry when the hot water inlet pipe and hot water outlet pipe of the floor heating at home are not hot. Let's go to the neighbor's house first to see if your floor is like this. I'll also help you drain the water after confirmation to see if it's a main pipe problem. If it is the main pipeline problem, please ask the property management company to help you or the floor heating company to deal with it. If the problem of floor supervisor is ruled out, what other problems will cause the hot water inlet pipe and hot water outlet pipe of home floor heating not to be hot? How to solve it?

First, we have to deflate. Maybe there is too much gas in the floor heating pipe.

We can try to deflate the floor heating pipeline, and deflate each pipeline, because if there is a lot of air in the floor heating pipeline, it will hinder the heat transfer in the floor heating pipeline, resulting in the water in the outlet pipe not being hot, so the first thing we have to do is deflate. Solution: First, we close the main backwater valve of the floor heating water separator, then close all the branch valves of all the water separators, and then we can open the main water supply valve of the floor heating. Finally, we open the branch valves in groups, so that the air in the water pipe is discharged by pressure impact again and again.

The floor heating filter is often cleaned, and the blockage of the floor heating management filter is also one of many reasons.

If you don't know what the floor heating filter is, you only need to look at the main valve of the floor heating. Y-type filter is generally used for floor heating filtration, which is installed at the water separator of the water inlet pipe of the floor heating pipeline. If it is blocked here, it will directly cause a small amount of hot water to enter the water pipe, so the water inlet pipe will be hot and the water outlet pipe will not be hot. Solution: First turn off the main water inlet valve, remove our Y-shaped filter screen, take out the filter screen, take out the garbage in the filter screen, then wash the filter screen with tap water, brush it with a brush, or put on a new filter screen and clean it, and then we can put the filter screen back.

Cleaning the floor heating and blocking the floor heating pipeline are often the reasons that cause the outlet pipe not to be hot.

Floor heating has been used for a long time, and it is not cleaned regularly. Sewage or scale in the floor heating pipe will block the low-level heating pipe, slow down the water circulation of the floor heating pipe, and cause hot water to turn into cold water before going out, so we should clean the floor heating every 2~3 years.

Solution: First, we remove the exhaust valve, connect a water pipe to the installation port of the exhaust valve of the water separator, then close the main return valve, then open the main inlet valve, close the small valves of each branch, and finally open the sewage one by one until the clean water is discharged. This method can only discharge sewage, but it can't play a cleaning role. I suggest inviting professional floor heating cleaning personnel to help us clean the floor heating water pipes, which can effectively solve the problem of blocking the floor heating hot water pipes.

Install booster pump, the floor is too high and the heating water pressure is not enough.

Now it's all central heating, and often the heating at the bottom is particularly hot, but it's not hot above. All these may be because the property opens the heating valve too small, and the hot water is too hot when it reaches the top, so there will also be insufficient pressure. The hot water in the floor heating pipe cannot be circulated in a short time, so the water in the floor heating outlet pipe is not hot.

Solution: Installing a booster pump for household floor heating can effectively increase the hot water pressure and shorten the hot water circulation time of floor heating, thus solving the problem that the water outlet pipe is not hot.

The above is the reason why the hot water inlet pipe and hot water outlet pipe at home are not hot and the treatment methods!
