Why is the heating not hot? Various reasons and solutions.

The heating system is not hot, and there is air blockage in the heating pipe.

1, the cause of the heating system

To check whether the heating system is blocked, you can touch the pipe connecting the heating first. If the pipe is not hot, the heating system may be blocked. The blockage may be due to the fact that the heating pipeline has not been maintained for many years, and a large amount of scale and sediment accumulation lead to scaling on the inner wall, increased thermal resistance and poor water flow; The central heating area may be caused by closing the valve of the main pipeline by mistake.

There is an air plug in the heating pipe.

Check whether the system flow is too low or whether the air content of circulating water in the system is too high. Touching the heater by hand is cold, which may be caused by the failure of the drain valve of the heater, which leads to the accumulation of a large amount of air in the heater and makes the heater not hot; There is water in the heater, or there may be gas in the radiator that can't be discharged.

Precautions for using heating:

1. Adjust the appropriate temperature: When using floor heating in winter, many people like to adjust the temperature higher, but it is unwise to do so. Although warm, it is easy to cause dryness, which in turn affects health. The suitable temperature for heating in winter is generally around 20℃, which can ensure warmth and health at the same time.

2. Pay attention to air circulation: being in a closed environment for a long time has a negative impact on people's health. When using floor heating or radiator in winter, we should pay attention to opening the window regularly for ventilation, and at the same time, don't always stay indoors, go out for a walk properly, and better adjust our body and mind.
