Floor heating has now become the new fashion for winter heating. However, as the service life of the pipeline increases, the problem that the floor heating gradually becomes less hot also troubles some users.
Geothermal pipelines need to pass through water as a medium, and water contains many substances. It can be roughly divided into two categories: one is minerals, calcium, magnesium ions, etc.; the other is microorganisms. Because the geothermal system will produce a large amount of calcium and magnesium ion scale, biological sludge, rust and sediment on the outer pipe network after a period of use; the chemicals used by heating enterprises to prevent water theft also adhere to the inner wall of the geothermal pipe, causing the geothermal pipe Blackened or blocked, loss of heating function.
It is very important to choose a good heating pipeline before heating installation, but also pay full attention to the regular maintenance and cleaning of the heating pipeline during use, which is an important measure to maintain and improve the thermal efficiency of the heating system.
Under normal circumstances, the geothermal pipeline will deposit {{0}}.5mm of scale and slime after a heating period, and correspondingly reduce the indoor temperature by 3-6 degree , which is more serious in areas with poor water quality. The thermal conductivity of the scale is poor. During the heat exchange process, the scale increases from 0mm to 0.3mm, and the heat exchange rate will decrease to 79 percent . Moreover, the heat exchange rate will decrease sharply with the increase of scale thickness, which is why people feel that the floor is not hot or not.
Therefore, in order for the floor heating to maintain a good heating effect and have a longer service life, users should pay attention to the protection and maintenance of the floor heating. The most important thing is to clean the floor heating pipes. The time of floor heating cleaning can be before heating, during heating or after heating. Cleaning before heating can remove all impurities such as biological slime in the pipeline, so that the heating effect can reach the best state; cleaning during heating can obviously feel the change of temperature rise; cleaning after heating is relatively better , It can clean impurities and prevent algae bacteria from multiplying in the floor heating pipeline. Under normal circumstances, floor heating should be cleaned once after 2-3 years of use.
