Heating pipe scaling affects heating, teach you to solve this!

Geothermal pipes need to pass through as a medium of water, water contains a lot of material. Generally can be divided into two categories: one is minerals, calcium, magnesium ions, etc.; The other is microbes. Due to the geothermal system after a period of use will produce a large amount of calcium and magnesium ion scale, biological mud, rust outside the pipe network, sediment; The chemical agents used by heating enterprises to prevent water theft are also attached to the inner wall of the heat pipe, causing the heat pipe to become black or blocked, and losing the heating function.

It is very important to choose a good heating pipeline before heating installation, but also to pay full attention to the regular maintenance and cleaning of heating pipeline in the process of use, which is an important measure to maintain and improve the thermal efficiency of heating system.

Under normal circumstances, geothermal pipeline in the operation of a heating period will deposit 1 ~ 1.5mm scale, clay, and corresponding indoor temperature is reduced by 3 ~ 6℃, the water quality is more serious. The thermal conductivity of scale is poor. In the process of heat exchange, the scale increases from 0mm to 0.3mm, and the heat exchange rate will be reduced to 79%. In addition, the heat exchange rate will decrease sharply with the increase of scale thickness, which is why people feel that the floor is not hot.

So in order to make the floor heating can maintain good heating effect, can have a longer service life, users should pay attention to the implementation of protection and recuperation of floor heating. The main thing is to clean the floor heating pipeline. 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 as to make the heating effect reach the best state; Cleaning in heating, you can obviously feel the change of temperature rise; And cleaning after heating is relatively better, can clean impurities, prevent algae in the heating pipeline propagation. In general, the floor heating should be cleaned once after 2-3 years of use.
