How to solve the problem of non-circulating backwater in heating

The heating solution without circulating backwater is as follows:

1. After the backwater valve is closed, open it. It should be noted that not only the return valve is closed, but also the inlet valve is closed. Moreover, for the good circulation of hot water, the inlet valve and the return valve should not be half open, but fully open.

2. It solves the problem that the backwater is not hot because of the gas in the pipeline, which is also a good problem. Just open the air valve to deflate until columnar water with few bubbles flows out of the air outlet.

3. The pipeline blockage is very troublesome. If the backwater is not hot because the filter has not been cleaned for a long time, just remove the filter and clean it; But if the backwater is still not hot after cleaning the filter, you need to contact a special company to solve it.

4. If the water pressure is insufficient, you can contact the heating company or the property to solve it. If it is not solved, installing a circulating pump to improve the circulation of hot water can generally solve the problem.

Heating cleaning method

I. Cleaning and maintenance of radiator surface

The radiator is fixed on the wall of the house all the year round. Under the action of hot air, the dust in the air will inevitably accumulate in the gaps and dead corners of the radiator. Therefore, in the cooling period in summer, it is necessary to brush off the dust on the surface with a clean towel with detergent and cover it with a cover.

Second, the radiator internal cleaning and maintenance

This step is generally aimed at the radiator at home, which has been used for several years and has never been cleaned. During the shutdown, it is necessary to clean the radiator inner pipe and system pipe at home. Avoid excessive pollution and impurities attached to the internal pipes of the radiator, which will directly hinder the thermal cycle of the radiator after blockage.
