The reason why the radiator is not hot and the solutionDate：2017-05-25 11:21:57 Browse :
1. The first thing you need to do is to find a more professional installer when installing the heater. Give a reasonable heating design according to your own situation, including the number of radiator sets, the diameter and direction of the heating pipe, and the heating pipe with the radiator. The connection of the group, in addition to the air-heating, the other need to connect the radiator group to the upper and lower, or the lower and lower to make the heating and hot water flow smoothly, only the hot water circulation can warm the heat.
2. It may be that the valve flow of the household is too small.
When the heating is supplied to the home, there is usually a valve to control. If the radiator is not hot, it is very likely that the valve is too small. At this time, just open the valve to increase the water flow. After a while, the radiator will change. heat.
3. The radiators and pipes in the home are not hot.
This situation may be caused by the total valve of the heating system. The total valve is generally in the inspection well of the unit stairs. We only need to check the supply and return valves and confirm that it is open.
4, the radiator in the home is not hot, but the pipeline is a bit warm.
This situation may be caused by the home to prevent the radiator from rusting. Before the end of the heating in the previous year, the grouping valves of each group of heating are turned off. This prevents the air from entering the heating and causing the heating to rust and rot. The sub-valve of the heating is opened.
5, half of the radiator is not hot, there is water sound in the heating, or the temperature of the radiator is not as high as other people's home.
This is because there is air in the radiator group, and it is necessary to open the valve to deflate until water flows out. The method of deflation, on the upper side of the radiator, the toilet heating at the top, there is a deflation valve that can be adjusted with a screwdriver, rotates counterclockwise, the air in the heating is released, the heating can be heated, depending on the situation Deflate several times until it is exhausted.

The reason why the radiator is not hot
6. The radiator in the house is very hot, but the temperature in the house is not high.
This situation may be that the power of the heating is too small. Now the renovation of the home has replaced the original design of the radiator group, but the quality of the newly installed heating construction personnel is not uniform, and it is impossible to fully consider the specific situation of your home. There is less installation of your radiator group. At this time, you need to ask the professionals to help, and redesign the number of radiators.
7, the heating temperature of the home is not the same, some are very hot and not hot.
This situation is mainly caused by uneven flow of hot water in each heating or uneven distribution of internal resistance. It is necessary to adjust the inlet valves of each radiator separately. If it is not possible after commissioning, it may be blocked in the non-heating heating. In the case, professionals need to be dredged and repaired.
8. All the heating in the home is close to the heat of the entrance door, and the farther away from the entrance door, the lower the temperature.
Close a group of heating, all the heating is not hot, this is because the radiator group is caused by the series connection, for example, the water temperature of the inlet pipe is 75 degrees, after the first group of heating, it becomes 65 degrees. After entering the second group, the temperature may be lowered to 45 degrees, and then the temperature will be lower, and the radiator will not be hot. This situation should be contacted by professional maintenance personnel as soon as possible.
9. It may be that the foreign object in the radiator is blocked or the pipe is blocked.
The air and dirt in the radiator block the radiator and make the water flow smaller. At this time, as long as it is cleaned, the radiator will become hot after a while. Be sure to clean up foreign objects. The pipeline is blocked due to the non-warm period, and the pipeline is usually in a venting state. Due to the oxidation of the dry and wet alternate environment, rust may be generated to block the pipeline. The treatment method is to unload the joint for inspection.
10. It may be caused by a leak in the pipe.
Carefully inspect the pipelines. If there is any leakage, find a professional to repair it in time to avoid the water flow is reduced and the radiator is not hot. Specifically, you can consult online or refer to the radiator leaking.
11. The heating pipe temperature is not enough, the inlet water temperature is low, and the inlet water temperature is increased. This situation requires a property inspection system.
12. The installation method of the radiator is wrong.
The performance is: the number of pieces of the radiator is hot, or only the heat of the main tube below. For example, the four-opening (also called the upper and lower) radiators are installed into the lower and lower outlets, and the water will flow directly from the lower main pipe. Only the lower main heat is used, and the heat sink is not hot, and the radiator is installed as follows. It’s going up and down, there will be some pieces that are not hot, and so on. Solution: Find a HVAC company that installs the radiator to reinstall or change the radiator.
13. The radiator is returned to the water pipe.
The performance is as follows: in the case that the supervisor is not reversed, the radiator is heated above the top, and the heating effect is worse than normal. Solution: Look for a company that installs the radiator or a professional maintenance person to adjust it.
14. The heating supervisor was reversed.
The performance is as follows: the upper and lower radiators are hot first, and the upper ones are hot, and the temperature of the heat meter is lower than the temperature of the other main pipe. The damage caused by the supervisor is very high. Not only the heating effect of the radiator is poor, but also the heating water flows into the indoor heating system from the return pipe without the filter installed, and the radiator and the pipe are easily blocked by the stolen goods.
Solution: If the water supply is wrong, find the property company to adjust it. If only the household supervisor is reversed, the company looking for the indoor heating system will adjust it.
15. Wear a “coat” for the radiator to affect the heat dissipation.
In order to make the radiator look beautiful, many families put on the "outerwear" - the radiator cover. However, according to professionals, the heating of the decorative cover will first affect the conduction, convection and radiation of heat, thereby reducing the heating effect. According to the statistical results, the room temperature of the enclosed radiator can be different from room temperature by 3 ° C to 5 ° C. In addition, the surface of the radiator should not be stacked with items that hinder heat dissipation.
16. Private heating has destroyed the balance of the heating system.
The indoor heating system is strictly designed, constructed and installed. If the user privately transforms the radiator system or installs the pipeline pump and heat exchanger without authorization, it will destroy the hydraulic balance of the heating system and cause the hydraulic imbalance of the indoor system. Stable and normal operation of the user or the entire heating system. In addition, due to the lack of necessary professional skills in private installations and privately-controlled heating facilities, it is extremely prone to water leakage due to the closure of the heating valve, and even damage to the heating equipment, which affects the heating effect.
17, the house insulation measures are not enough to make the radiator look not hot.
In the winter, users often hear that “the radiator is very hot, but the home is not hot”. In fact, the warmth of the heating room has a great relationship with the quality of the heating. If the house insulation measures are not in place, the indoor temperature will not go up, and window leakage is the most common problem. St. Lawrence said that residents can use some sealing strips for heat preservation; if there are cracks in the outer frame and wall and the cracks are large, it is necessary to first fill the polyurethane foam and then use the glass glue. If the gap is small, you can directly use the glass seal. .
18, the traditional old-fashioned radiator heat dissipation is poor.
Some old-fashioned cast iron radiators are not only ugly in appearance, but their heat dissipation effect is also unsatisfactory. Because the old radiator pipe is thin, the thermal conductivity of iron is lower than other materials. Under normal circumstances, the heating area per piece is about 1.5 square meters, which is much lower than that of the new radiator, and the heat dissipation effect is greatly reduced.
