What are the common problems and solutions of radiator not being hot?

Briefly summarize the common problems and solutions of radiator not being hot. You can judge according to your actual situation and find the corresponding solution.

1. The radiator is blocked by air, mainly because there is air inside.

Problem performance: the radiator is half hot and half not hot, mainly because the residual air in the radiator pipeline blocks the pipeline, which affects the water circulation of the pipeline and leads to uneven heat dissipation.

Solution: Open the air outlet of radiator and exhaust it for many times to ensure the air in the pipeline is emptied.

Tip:

1), turn off the heating valve at home first;

2), find the radiator exhaust valve, generally in the upper left or upper right of the radiator;

3) After drinking water, find a mineral water bottle, and punch holes on both sides, one as big as a warm air valve and the other as big as a screwdriver.

4) Fix the drilled mineral water bottle and the hole with the same size as the radiator valve on the radiator valve, and gently loosen the bleeder valve on the other side with a matching screwdriver, and stop twisting when you hear the sound of deflation;

5) After the gas is discharged for a period of time, water will flow out. When the water flow is stable, close the bleeder valve. If the heating can't be heated up at one time, you can put more water and the heating will heat up slowly.

2. The temperature control valve is not fully opened.

Fault manifestations: Some rooms have hot radiators, while others don't. For example, the radiator in the living room at home is not hot, and the radiator in the bedroom is hot.

Solution: Check the temperature control valve and water inlet valve on the water separator to ensure that each temperature control valve and water inlet valve is open.

3. The radiator is blocked by sundries

Fault performance: the heating effect of radiator is getting worse year by year. If the general fault is eliminated, it is likely that the radiator or heating pipe is blocked.

Solution: don't disassemble it at will, you need to find a plumber to deal with it.

04. The installation position of radiator is unreasonable or it is installed backwards in return pipe.

Fault performance: All radiators in the house supply heat normally, but the room temperature always fails to meet the requirements. The main manifestations are: the lower part of the radiator is hotter than the upper part, the heating effect is worse than normal, some parts of the radiator are hot, or only the main pipe below is hot.

Solution: Find a reliable plumber and redesign the radiator.

05, radiator quality problems

Fault: Everything else in the house is normal, and the radiator is installed in a reasonable position, but the radiator is not hot. Then it may be that the radiator itself cannot dissipate heat.

Solution: Before buying a radiator, you should know the heat dissipation area of the radiator. If you are worried that the radiator's heat dissipation capacity will be lost in the middle, it is suggested to calculate according to the radiator's heat dissipation area *0.8, which will be more stable. For example, the area of your bedroom is 10 square meter, and the heat dissipation area of an 80m radiator is 1 square meter. If you simply calculate the heat dissipation area, you only need to buy 10 column, but it is better to consider the actual heat dissipation power consumption, and it is better to buy 12 column or 13 column, which is better.
