What causes the low geothermal backwater pressure?

The floor where you live is high, and geothermal energy can appear at the heating end of the community. The pipeline pressure in the return pipe is not enough, which leads to unsatisfactory heating. The solution of geothermal return pipe is not hot: if so, you can only find a heating company or property to solve it; If it can't be solved, a circulating pump can be installed to improve the circulation of hot water and achieve the ideal heating effect.

2. There is gas in the pipeline

Generally, when there is gas in the geothermal backwater pipeline, the main geothermal rod is hot and the backwater rod is not hot, resulting in hot water not only entering the loop, but also not circulating. Solution to the problem that the geothermal return pipe is not hot: If there is air in the pipe and the geothermal return pipe is not hot, you can open the exhaust valve on the water separator to release air until the water comes out.

3、? Uneven coil

In the same community, other residents have good heating effect, but their own heating effect is not good. This phenomenon is generally caused by the uneven geothermal return pipe loop. The solution of geothermal return pipe is not hot: If the construction loops are uneven, then the small valve on the water separator can be used to adjust the circulation quantity of each loop, with the return pipe "cross" as off and "one" as on, so that the circulation can be uniform and the ideal heating effect can be achieved.

Precautions for floor heating:

1. When installing floor heating, the installation should be safe and planned. The installation of floor heating is not without layout. On the contrary, the layout of floor heating installation needs to be careful. It is necessary to consider the layout of floor heating according to the use area and the insulation effect of the room, design the reasonable direction and spacing of floor heating pipes, and provide the most suitable heat dissipation for the room according to the radiation principle.

2. Floor heating is realized by plastic pipes or heating cables hidden under the floor, so the quality of heat medium transmission materials and insulation materials such as pipes hidden under the floor is the main reason that affects the service life of the floor.
