I find that the floor heating is getting less and less hot. Is there any way to fix it?

One reason, which is also the most important reason that affects heating, is that the water circulation is not smooth due to the small pressure difference between supply and return water, and the water flow of hot water is too small, which leads to return pipe not being hot. The high temperature of the "water inlet" indicates that the problem is at home, and it is relatively easy to solve it: open the main control valves one by one to see which pipe is blocked, or more than one pipe is blocked. With the passage of the season, when the weather turns warmer and indoor heating system is no longer needed, it should be noted that the shutdown of geothermal system should have a process, and the cooling process of the floor should be gradual and not sudden.

Whether the floor heating is hot or not, we must first confirm whether the property has normal heating. If the heating is normal, the problem is at home. Check whether the floor heating water inlet switch at home is turned on. Someone may have turned off the floor heating water inlet switch because of stopping heating or other reasons. If the effect of floor heating used to be normal, it's just that it's not hot this year. It may be that after living for a long time, the floor heating pipe will produce impurity scale after use. We can't clean it ourselves. We can find a professional floor heating cleaner to help us clean the floor heating coil. Personally, I think floor heating should be thoroughly cleaned after being used for more than five years.

When laying floor heating, the length of each pipeline should be consistent. If it is not consistent, it is necessary to add a regulating valve to ensure a balanced flow of all waterways and prevent some houses from being hot and some houses from being cold. The unreasonable operation and brutal construction of the construction personnel lead to the dead bending and flattening of the pipeline, poor water flow and increased resistance. All the above are the reasons why the floor is warm and not hot. I would also like to remind you that the floor heating will heat up slowly when it is used for the first time, and it needs to be heated step by step.

Generally speaking, the common fault of indoor floor heating is that the cement mortar laid by floor heating is too thick (10 cm or more); The floor heating pipeline is blocked and dirty, which needs to be cleaned and dredged. The opening of the floor heating valve is small, so the floor heating valve should be replaced.
