Why is it not hot to change the floor heating on the sixth floor of the water heating room?

What is the reason why the floor heating is not hot? Additional solution

Now many families use floor heating in winter. The floor heating temperature is high and uniform, so it is very comfortable to stay at home in winter. However, what is the reason why the floor heating is not hot? What if the floor heating temperature is not enough?

Insufficient pipeline pressure

Phenomenon: Some residents' floors are too high or the heating in the residential area is not completed, and the pipeline pressure is not enough, which leads to unsatisfactory heating.

Solution: the circulating power of the floor heating heat source is insufficient, and the return water of the floor heating may not be hot, because the water needs a certain pressure to circulate in the floor heating pipeline. If the pressure is not enough, the backwater will not be hot. This situation needs to be solved by a heating company or property. If it cannot be solved, it is suggested to install a circulating pump to improve the circulation of hot water and achieve ideal heating effect.

There is gas in the pipeline.

Phenomenon: the main pole of floor heating is hot, and the return pole is not hot. It is because there is gas in the pipeline that hot water cannot enter the loop for circulation.

Solution: First close the backwater valve, and then manually open the exhaust valve for floor heating. Each valve on the inlet water should be closed first, and then all the exhaust gas should be opened. There may be water overflowing during the exhaust process. You can find a small basin to catch water, wait for half an hour after the air in the floor heating pipe is completely exhausted and heated. Many times, return pipe is not hot, which is also related to the exhaust.

Uneven coil

Phenomenon: other users in the same community have good heating effect, but their own effect is not good, and the floor heating construction loop is uneven.

Solution: Use the small valve on the floor heating water separator to adjust the circulation of each loop to make it circulate evenly and achieve the ideal heating effect.

The valve is not open.

There is hot water in the water inlet pipe of floor heating, which is hot, but not hot in return pipe. This situation is probably caused by the main valve not being opened. Solution ~ I suggest you check the main valve on the floor heating main pipe and the distribution manifold in turn to see if there are any valves in the closed state. If yes, opening them can solve the problem that the floor heating is not hot in return pipe.

At the end of the heating period, not all the water is discharged.

After the annual heating period, floor heating users should discharge all the boiler pipe water in the geothermal pipe network. Because the boiler tube water contains many tiny particles such as mucus, impurities and rust slag, the water quality is turbid and the inner diameter of the floor heating pipe network is very thin. For example, when the boiler stops gas and the water pump stops running, the original sewage impurities will stay in the pipe network for 7 months, and the precipitation of calcium, magnesium, salt and other substances contained in the water will generate hard scale hanging on the inner wall of the floor heating pipe network, which is more bent, even if there is pressure water flow, it will not be washed away. If the scale is not removed for a long time, the flow rate will be reduced, the running water will be blocked, the thermal radiation value will be reduced, and the pipe network will be blocked and cannot be cleaned, and the whole geothermal pipe network will be scrapped.

Geothermal construction problem

Construction personnel with low quality, without professional training, brutally constructed pipelines, resulting in dead bending and flattening, resulting in poor water flow and increased resistance. Row spacing does not meet the design requirements. Before the installation of the floor heating pipe, the sundries in the pipe were not carefully cleaned and kept clean, which led to the blockage of the pipe.
