Huimin County: Isn't the heating at home hot? Here comes the hint from the heating company.

Home heating is not hot, Huimin County Thermal Power Company prompts as follows:

Usually in the early stage of heating, it is often reflected that the heating is not hot. Because the whole system and room need a process of heat transfer and heat storage, the temperature is gradually rising. In the meantime, residents should try not to open doors and windows often. The five-step method of rapid heating in the early stage of heating is recommended to everyone, and simple problems can be handled by your own judgment.

Touch: Touch the water separator or radiator gently with your hand to feel whether it is warm or not. At the beginning of heating, the heating water temperature is generally not high because of the high outdoor temperature. As long as you feel the warmth of each water separator or radiator, you can judge that the heating is normal.

The second question: ask the neighbors or the managers and property managers of the heat exchange station to find out whether the heating system in this community is operating normally. In the early stage of heating, due to the maintenance of heat exchange station facilities, water leakage of pipe network and other reasons, sometimes heating can not operate normally, so the maintenance progress can be tracked.

Third inspection: check whether the valve of your indoor heating system has been turned on. Indoor heating valves are mostly ball valves, and the valve stem opens in the same direction as the pipeline and closes vertically. If you need to open the valve, remember not to use tools or use too much force.

Four rows: in the early stage of heating, many users are not hot because there is gas in the system. Open the vent needle in the upper right corner or upper left corner of the radiator to vent. Pay attention to carefully screw the deflation needle when exhausting, stop when you hear the "hissing" deflation sound, and screw it again when there is water flowing out. Generally, when this happens in the early stage of operation, it needs to be operated several times repeatedly until the radiator is completely heated. Note: Be careful in the above operation, and don't force the exhaust valve too hard to fall off.

Five reports: After the above four steps, the heating in your house is still not hot, so you can contact the maintenance personnel to handle it at home.

Working principle of heating

Radiators are mainly made of cast iron, steel, aluminum and copper-aluminum composite. Aluminum and copper-aluminum composite radiators have a small market share and belong to complementary products. Heating can be divided into water heating and air heating. Usually radiator refers to water heating, that is, circulating water is heated by wall-hung boiler or boiler, and then linked to radiator through pipeline. Finally, the appropriate temperature is output through the radiator to form the indoor temperature difference, and finally, the whole indoor temperature is evenly increased through thermal circulation.

Warm air is hot air. As soon as the cold air comes in, it is heated into hot air by the radiator. Hot air rises and forms convection with indoor cold air. Cold air circulates near the heater and is heated into hot air. Hot air circulates in the house and the room is warm.
