The heating is connected in series, which makes each room colder and colder.

There are two kinds of blockage here, one is that the top floor residents close or partially close the pipeline valves, and the other is that the heating system has not been maintained for many years, and a large amount of scale and sediment accumulate in the pipeline, which leads to pipeline blockage. At this time, the solution can only be solved by property management personnel.

There is gas in the radiator.

If the hand touches the heater, it is cold. It may be that the drain valve of the heater is out of order, resulting in a large amount of air accumulated in the heater, which makes the heater not hot. At this time, the solution is to gently loosen the screw above the heater until water is sprayed out, and then tighten the screw.

Precautions for radiator:

1. After a heating season, there will be impurities such as rust in the central heating pipeline. The heating unit will use the intermittent period after stopping heating to pressurize the heating pipeline. If residents forget to close the exhaust valve, there may be water leakage at home.

After the heating is stopped, residents should not let the radiator and the water in the pipeline run away. Most radiators need full water maintenance, so it is very important to close the inlet and outlet valves of radiators when stopping heating, which is very important to prolong the service life of radiators.
