Floor heating pipeline scaling impact heating, teach you to solve!

Geothermal pipelines need to pass through the medium of water, water contains a lot of substances. Generally can be divided into two categories: one is minerals, calcium, magnesium ions, etc.; The other group is microbes. Due to the geothermal system after a period of use will produce a lot of calcium and magnesium ion scale, biological mud, external pipe network rust, sediment; Chemicals used by heating enterprises to prevent water theft also attach to the inner wall of the geothermal pipe, causing the heat pipe to become black or blocked, and the heating function to be lost.

It is very important to choose a good heating pipeline before heating installation, but we should also pay full attention to the regular maintenance and cleaning of the heating pipeline in the process of 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 1 ~ 1.5mm scale and mud after a heating period, and correspondingly reduce the indoor temperature by 3 ~ 6℃, and the area with poor water quality is more serious. However, the thermal conductivity of scale is poor. In the process of heat exchange, when the scale increases from 0mm to 0.3mm, the heat exchange rate will decrease to 79%. In addition, the heat exchange rate will decrease sharply with the increase of scale thickness, which is why people feel the ground is not hot.

So in order to make the floor heating can maintain a good heating effect, can have a longer service life, users should pay attention to the implementation of protection and recuperation of the floor heating. The main thing is to clean the heating pipeline. The cleaning time of the floor heating is before, during or after the heating. Cleaning before heating can clean all the impurities such as biological slime in the pipeline, so as to achieve the best heating effect; Cleaning in heating can obviously feel the change of temperature rise; It is relatively better to clean after heating, which can clean impurities and prevent algae and bacteria from multiplying in the heating pipeline. In general, the floor heating should be cleaned once after 2-3 years of use.
