Keywords: how to solve the radiator is not hot
First, the radiator impurities are blocked or the modification is not hot.
After the radiator is modified privately, the installation details are not in compliance, so the temperature of the radiator will naturally be affected. In some cases, the pipeline may be blocked by impurities, resulting in blocked system circulation and poor heat dissipation.
Solution: Please ask professional HVAC maintenance personnel to make on-site inspection, clean up the silting part or redesign the installation.
Second, the radiator is blocked.
Some household radiators are not hot because a large amount of air has accumulated in the heating system, commonly known as "air blockage". After the gas blockage, it is difficult to circulate hot water, which leads to the heat dissipation of the radiator being affected and extremely slow.
Solution: Exhaust the excess air in the radiator cavity. At the top of the radiator, there is an exhaust valve. Turn the valve counterclockwise, and be careful not to let the water in the cavity flow out in large quantities. It needs to be deflated several times until it is exhausted.
Third, whether the radiator valve is opened normally.
At the beginning of heating, users should conduct a comprehensive inspection of the whole radiator heating system. Make sure that the valve of the radiator opens normally. Generally speaking, the radiator valve is adjusted before leaving the factory, and there are basically only two directions. When the handle is parallel to the pipeline, it is open, and when it is rotated 90 vertically, it is closed. If the valve is not fully opened, the heating effect of the radiator will be greatly affected.
Solution: The valve handle can be tightened parallel to the branch pipe.
Four, radiator water pipe temperature is low, hydraulic imbalance.
Water pressure imbalance often occurs in single-cycle installation system. If the radiator is turned off, the radiator that is not hot becomes hot, which is caused by indoor hydraulic imbalance. In addition, there are many heating families in many central heating areas. At this time, if the terminal heating temperature is not raised, the radiator will not heat up no matter how good it is.
Solution: When opening the radiator, pay attention to opening the radiator that is not hot first, and then open other radiators after the temperature of the radiator rises gradually to ensure normal work. If it is the pipe temperature problem of the whole community, you need to contact the heating company to adjust the temperature.
In addition to the above common problems, the radiator at home is not hot, which is related to the quality and material of the radiator itself. A set of high-quality radiators is also one of the keys to ensure heating comfort. Therefore, when you buy radiators, you can choose radiators of reliable brands, and the relative quality of radiators of big brands is guaranteed after sale ~
